The words of afeique

Aboard the USS Reliant – Incursion

Lieutenant Commander Mark Davis braced himself against the chart table as a sudden jolt ran through the USS Reliant. The nuclear submarine lurched in the dark ocean depths, sending coffee sloshing out of mugs and crewmen stumbling. A klaxon began blaring an ear-splitting alarm. WHOOOP! WHOOOP! Red emergency lights blinked on, bathing the cramped control room in a blood-colored haze. Mark’s heart pounded. One moment they’d been on a routine deep-sea patrol, the next the boat shuddered as if something massive had collided with the hull.

“What the hell was that?” someone shouted over the siren. Mark steadied himself and scanned the console readouts. The ballast pressure in one of the forward tanks was spiking off the charts. Internal breach? That made no sense. There was no impact from outside on sonar. Yet the gauges told another story: Ballast Tank 4 was flooding uncontrollably, far beyond normal intake.

“Seal ballast four and report!” Mark barked into the comm, fighting to keep his voice level. He was the executive officer, and the crew needed calm leadership now. Static hissed back – internal communications were crackling with interference. Mark exchanged a tense glance with the Reliant’s captain across the dim control room. The captain nodded sharply, silently urging Mark to take charge of the emergency. Mark snatched a handheld radio and toggled to the engineering frequency.

“Engineering, report status!” he ordered. For a second, only distortion answered. The lights flickered, consoles on the bridge sputtering as power fluctuated. Mark’s skin prickled with a sudden dread – a high-pitched whine seemed to resonate through the hull, just at the edge of hearing. It set his teeth on edge, like the keening of some underwater siren. Several crewmen clapped hands to their ears in discomfort. Mark’s vision swam; for an instant he thought he saw the control room walls ripple, as if the submarine itself were breathing. He blinked hard and the illusion was gone, but his unease deepened. Something was very wrong, in ways he couldn’t yet quantify.

Through the haze of alarm sirens and that strange whine, a voice finally crackled from the radio: “Engineering to Bridge – we’ve got a…” The transmission dissolved into static. Mark smacked the radio. “Say again, Engineering!”

A burst of panic cut through the static: “…breach in the engine room! Flooding in compartment six—” The line went dead with a screech of feedback. Mark didn’t hesitate. He grabbed a flashlight from the wall. “XO to Damage Control teams: meet me at Engine Room access, deck 3. Move!”

He sprinted down the narrow passageway, using the bulkhead railings for balance as the deck still quivered beneath his boots. Two sailors followed close behind: Petty Officer Nguyen with a fire axe in hand, and Ensign Jonah Yates, wide-eyed but determined, clutching an emergency toolkit. Boom! Another impact – or explosion – rumbled from below, nearly knocking them off their feet. The lights guttered out for a moment, plunging the corridor into blackness. In that instant of darkness, Mark thought he heard a whisper right behind him, a wet hiss that almost formed his name: “Daaaavis…” He whirled, shining his flashlight, but there was only Nguyen and Yates, faces pale in the beam. Neither had spoken. Mark’s pulse thudded. Hallucination? He forced himself to breathe. Stay focused.

They reached the heavy hatch leading to the engineering section. Water was seeping out from under the door – far too much water. Something had definitely burst. Mark spun the wheel and heaved the hatch open. A wave of cold seawater poured out around their ankles, carrying with it a slick of strange blue fluid.

“God!” Yates exclaimed, stepping back as the blue slime oozed past his boots. Mark’s nostrils flared at the smell – an acrid reek like ozone and rotten eggs. In the beam of his flashlight, the liquid looked alien, an iridescent acidic-blue that swirled in the seawater. Nguyen gingerly touched the blue puddle with the blade of his fire axe. Sssss… The metal sizzled on contact, and Nguyen yelped, dropping the axe. The portion of the steel head that touched the fluid was corroding, a bubbling hiss eating a hole right into it.

Mark’s stomach tightened. What is this stuff? His mind raced. Some kind of chemical leak? Coolant? But nothing onboard was that color or corrosive to solid steel. And how would a chemical leak coincide with a ballast breach? None of it made sense.

“Careful,” Mark warned, ushering his men forward through the half-flooded compartment. The engineering section was chaos. Overhead pipes hung ruptured and sparking. The deck was slick with seawater frothing around their shins. Mark’s flashlight danced across the compartment, revealing contorted shadows of machinery. The main engine turbines were partly submerged, and a shower of sparks rained from a torn electrical conduit, casting erratic light. Amid the clutter, Mark spotted two figures: engineering crewmen, Thompson and Lee, struggling to lift a fallen support beam off a third man who lay motionless.

Nguyen splashed over to help them while Mark and Yates stepped around a cluster of broken pipes. As Mark moved, his flashlight caught something else on the deck – a trail of glistening blue slime, smeared as if something had slithered through. It led away from the gushing ballast valve that was now jammed open, flooding the compartment with seawater. The valve hatch itself was torn clean off, crumpled like foil. Mark’s heart pounded harder. An unaccounted breach indeed – something had forced its way in from the ballast tank.

“Lieutenant, over here!” Nguyen called. With his help, Thompson and Lee dragged the injured crewman out from under the metal beam. It was the chief engineer, Senior Chief Ortiz. His leg was twisted and he was barely conscious. “We’ve got to get him out—” Thompson began, but then paused, sniffing. “Do you smell that?”

A waft of pungent, chemical sweetness drifted through the air, cutting through the scents of oil and burnt wiring. It was sickly sweet and briny. Yates coughed, suddenly swaying on his feet. “I feel… dizzy, sir,” he mumbled. Mark realized he too felt light-headed; the edges of his vision flickered. The air itself seemed to shimmer with faint blue vapor. Some airborne toxin? He yanked a breather mask from a nearby emergency kit and strapped it over Yates’s mouth. “Put this on. All of you, masks now!” he ordered.

As the sailors fumbled for their emergency breathing masks, Mark heard a clatter somewhere behind the machinery. His flashlight beam swung toward the sound. Beyond a tangle of sparking cables, the darkness pooled deeper. The red emergency lights barely penetrated there, but something was moving. Drip… drip… A thick blue droplet fell from above, sizzling on the wet deck. Mark aimed his light upward, past the catwalk.

High in the corner of the compartment, an overhead ventilation duct grille hung askew, as if it had been forced open. The metal around its edges was corroded, melted by the same blue acid that now spotted the floors. A chill ran through Mark. Through the ventilation… he realized, goosebumps prickling his spine. The sudden breach hadn’t been an explosion at all. It was an intrusion. Something had crawled in through the vents.

Nguyen followed Mark’s gaze and sucked in a breath. “Sir… up there…” he whispered. They could just make out scratch marks scoring the metal bulkhead near the open duct. And around the vent’s opening, glistening in the flashlight beam, were the sucker-like imprints of tentacles.

Mark’s throat went dry. He motioned everyone to back away slowly. The group huddled together in the waist-deep water, half-supporting the semi-conscious Ortiz. “Easy now,” Mark murmured, barely above a breath. His eyes never left that gaping vent. The sweet stench in the air was stronger, making his head swim even through the mask. An overwhelming sense of presence pressed on him, raising gooseflesh on the back of his neck. It felt as if an unseen predator’s gaze had fixed on them.

Yates let out a panicked little laugh. “This isn’t real… I must be dreaming,” he babbled softly. Mark placed a firm hand on the young ensign’s shoulder to steady him. “Stay calm, keep your guard up,” Mark whispered. But his own heart hammered against his ribs. In the suffocating closeness of the flooded compartment, the air felt suddenly alive with menace.

For a long moment, the only sounds were the crackle of electricity and the labored breathing of the crew. Then came a new noise – a wet slithering followed by a gentle plop, as if something dropped into the water on the far side of the engine room. Mark swung his light toward the sound. The beam illuminated ripples spreading through the oily water… but the source was hidden behind a bank of humming generators.

Mark motioned to Nguyen and crept forward, leaving Thompson and Lee cradling Ortiz a few steps back. Yates followed on Mark’s heels, wrench in hand, breathing fast and shallow through his mask. They inched around the generator. The shadows here were dense, cluttered with pipes and cables overhead like grasping arms. Mark’s boots bumped against a floating object – a hard hat from one of the engineers, bobbing aimlessly. He nudged it aside, teeth gritted.

Just as he edged past the generator, a blur of movement exploded from the darkness. SPLASH—a surge of water and a flash of something pale and serpentine hurtling straight at them. “Look out!” Mark roared, shoving Yates aside.

A thick, muscled tentacle whipped through the space where Yates had just stood, cracking into Mark’s shoulder and knocking him against the bulkhead. He cried out as pain lanced down his arm. In the chaotic flashlight beam, Mark finally saw it – the intruder – and a spike of pure horror nailed him in place.

It was like an octopus the size of a man, yet wrong, hideously wrong. A knot of rubbery flesh bristling with spines reared up from the water. Multiple arms unfurled, suckers the size of fists clamping onto the pipes and ceiling struts to propel it forward. Its skin pulsed with shifting color, camouflaging one moment into the dark steel background, then flashing a stripe of bioluminescent blue along its side. In the strobing emergency light, the creature looked phantom-like, there one second and nearly invisible the next.

But its face – dear God – its face was the stuff of nightmares. Mark caught a glimpse of a bulbous head with ridges like some deep-sea devilfish. One enormous eye swiveled toward him, reflecting the flashlight in a ghastly reddish gleam. Below the eye, cartilage plates parted to reveal a circular maw lined with needle-sharp teeth, surrounding a hard, black beak-like mouth. The maw emitted a chittering hiss that resonated in Mark’s skull like nails on glass.

For a heartbeat, man and monster were frozen staring at one another. The c’thalhai – for what else could this abomination be? – clung halfway up the wall, suspended by three tentacles, while the remaining arms lashed and coiled with eerie intelligence. Water streamed off its pale gray hide, and Mark realized in a sick daze that it was smiling at him – or so it seemed, the way that beak hung open as if in vile glee.

“Open fire!” someone screamed – Nguyen. In his terror, the petty officer had drawn his sidearm. Muzzle flash lit the cramped space as Nguyen emptied three wild shots at the creature. The gunshots were deafening in the confined compartment. The first bullet sparked off a pipe; the second punched into the thing’s mass with a wet thwack. The c’thalhai shrieked, an ear-splitting, alien cry that reverberated through the hull. In a blur, it launched itself at Nguyen.

Before Mark could react, a muscular appendage slammed Nguyen against the ceiling with bone-crushing force. There was a loud crack – Nguyen’s cry cut off instantly as his body went limp, the pistol spinning away into the water. The creature’s tentacle coiled around the unconscious man, snatching him up. “No!” Mark shouted. He lunged forward, swinging his flashlight like a club, smashing it into the abomination’s flank. Another crewman – Thompson – rushed from behind and drove a crowbar at the creature’s mass.

With astonishing speed, the c’thalhai recoiled from Mark’s blow and lashed out at Thompson. A barbed, spined tentacle tip struck the sailor’s abdomen and punctured straight through. Thompson gasped, blood spraying from his lips as the tentacle lifted him off his feet like a skewered fish. The monster yanked Thompson backward into the shadows. Both man and creature vanished behind the machinery with a splash, leaving only ripples of bloody water. Thompson’s agonized scream gurgled, then fell silent.

Pandemonium consumed the engine room. “Fall back! FALL BACK!” Mark bellowed, choking down terror. Yates had been knocked down in the chaos and now pulled himself up, grabbing Mark’s arm. Mark hauled him bodily toward the exit. Lee and another sailor were already dragging Senior Chief Ortiz out the hatch, struggling through the rising water. The creature’s shrieks echoed, disorienting, seeming to come from every direction at once. The lights flickered erratically, plunging the compartment in and out of strobing darkness. In the flickers, Mark caught glimpses of the beast slithering through the rafters, Nguyen’s lifeless form still wrapped in its tentacle.

Mark and Yates stumbled into the corridor where Lee waited with Ortiz. “Seal it! Seal the door!” Mark ordered. Yates hesitated, eyes darting behind Mark at something. Over Yates’s shoulder, through the dim, Mark saw why – Thompson’s body had been discarded, floating face-down in the compartment, and above it the creature loomed, half-submerged and racing toward them in a surge of foam. Its many arms propelled it forward with terrifying speed.

Mark slammed the heavy hatch shut himself and spun the locking wheel with all his strength. BOOM! The hatch buckled outward as the creature slammed against the other side. The wheel spun under Mark’s hands, nearly wrenching free. He and Yates threw their weight against it, locking it down just as another tremendous thud dented the steel. The c’thalhai was ramming the door, trying to force its bulk through. Mark’s mind raced in panic – could it squeeze through the narrow hatch window or the cracks? He peered through the small round glass porthole set in the hatch. On the other side, lit by the submerged emergency lights, a mass of tentacles writhed, suckers suctioning hungrily against the glass. A single lidless eye peered through at him, unblinking and full of alien hatred. Mark felt a jolt of primal fear at that gaze.

“Get back!” he yelled, pulling Yates away from the door just as a hissing spray of fluid jetted through the hatch’s edges. The creature had spat at them – a mist of its acidic blue blood, weaponized. Tiny droplets landed on Yates’s forearm and face. “Ahh!” Yates screamed, slapping at his cheek as smoking burn marks appeared on his skin. He stumbled back down the corridor, wiping frantically at the sizzling blue slime eating into his flesh. Mark grabbed him, dragging the ensign away from the door as more acid dribbled through the now-pitted metal. A wisp of that fluid hit Mark’s sleeve, instantly burning a hole through the fabric and searing the skin beneath. He grit his teeth against the burn, desperate to put distance between them and the relentless pounding on the hatch.

“We have to contain it,” Mark gasped, half to himself. He slammed an emergency bulkhead switch on the wall. Thick steel shutters began sliding down, sectioning off the passageway leading to engineering. Through the small hatch window, Mark saw the creature flail, realizing its prey was escaping. It batted its heavy body against the hatch once more with a thunderous crash that reverberated through the deck – but then the bulkhead shutter clanged shut in front of the hatch, cutting off the creature’s advance. For now, the monster was trapped in the engine compartment.

Panting, Mark allowed himself a single shaky breath. Water still trickled under the sealed door, but at least the immediate threat was contained behind reinforced plating. In the relative quiet that followed, Mark became aware of groans of pain. Yates had collapsed against the corridor wall, mask hanging askew around his neck. Lee was further down the hall, tending to Ortiz and shouting for a medic through his radio. The submarine itself groaned too – metal creaking under stress. They could all hear the thing on the other side of the bulkhead, a faint scraping of tentacles against steel and an intermittent thump as it tested the barriers, each hit weaker than the last. Perhaps it was hurt, or retreating. Or maybe, Mark thought grimly, it was toying with them, waiting for another opportunity.

He knelt next to Ensign Yates. The young man’s arm was mottled with nasty burns where the blue acid had splashed. Yates was breathing in short, sharp gasps, eyes unfocused. Mark put a hand on his shoulder. “Yates… Jonah, look at me.” Yates’s eyes flickered to meet Mark’s. The chemical stench still hung thick; Mark’s own head buzzed with each breath despite the mask. “You’re okay, son. We made it out. It’s sealed in there,” Mark said, injecting confidence he did not feel.

Yates nodded weakly. “Th-that thing… sir, it killed them… it killed them all.” His voice was breaking, hysteria threatening to erupt. Mark gripped him by both shoulders. “Ensign, listen. We’re not done. We need to get to the control room, regroup with whoever’s left. We have to keep this sub afloat and get help. Do you understand?”

Yates blinked rapidly. His face was ashen, beaded with sweat. “Yes… yes, sir.” He swallowed hard, seeming to master himself. Mark managed a tight semblance of a reassuring smile and stood, helping Yates to his feet. Lee had splinted Ortiz’s mangled leg with a pipe and duct tape, and now together they lifted the injured chief engineer. “We’ll carry him topside,” Lee said, voice shaking but resolute.

Mark nodded. “Go. Get Ortiz to the infirmary and find the captain or the OOD. Tell them we have an intruder on board, contained for now in engineering. And have someone prepare the torpedo room as a fallback shelter.” Lee hefted Ortiz with the other sailor’s help and hurried down the passage, boots splashing in the thin layer of water.

Mark turned back to Yates to urge him along, but the ensign hadn’t moved. He was leaning against the bulkhead, one hand pressed to his forehead. “Jonah? You all right?” Mark asked, moving closer. In the dim red light, Yates’s skin looked strange – slick with perspiration, yes, but there was also a faint bluish tinge creeping up his neck from beneath his collar.

Yates lifted his face and met Mark’s eyes. Mark’s stomach did a flip. Yates’s pupils were dilated, and spider-webbed through the whites of his eyes were blue-tinged veins. “I… I don’t feel so good, sir,” Yates whispered. His voice had a wet, gurgling quality. He clutched his burned arm, and Mark saw with horror that the flesh around the acid burn was blistering with bizarre speed – dark blue streaks spreading outward under his skin from the wound site.

“Dear God,” Mark breathed, realization dawning. The c’thalhai’s blood – it wasn’t just acid; it was poison. Yates must have absorbed it through the burns. Mark had heard of certain octopuses whose venom caused paralysis or hallucinations. Whatever cocktail ran in that creature’s veins was now pumping through poor Yates.

“Stay with me, Jonah,” Mark said urgently. “We’ll get you to medical.” He hooked an arm under Yates to support him, but the ensign cried out in pain. “It’s in my head…” Yates groaned. “Burns… everywhere… I can hear… I can hear it in my head…” He pawed at his temples, fingers leaving smears of blue-tinted blood – his ears were bleeding.

Yates suddenly convulsed, nearly knocking Mark over. Mark eased him to the deck as gently as he could while the young man’s back arched and a froth of saliva bubbled from his lips. “No, no, no…” Mark muttered, panic rising. This was beyond any medical help he knew. Yates spasmed, his heels drumming the metal deck. Mark struggled to keep him from hurting himself. The veins under Yates’s skin stood out in stark relief, tracing bluish-black lines all along his neck and jaw. His eyelids fluttered and when they opened again, the eyes were murky blue, as if flooded with ink.

“Sir…” Yates gasped out between clenched teeth. His voice warbled, a strange double-tone to it. He seized Mark’s sleeve. “Kill me,” he begged hoarsely. “It’s inside me… changing me.” His fingernails had turned an unnerving shade of purple and dug into Mark’s arm with unnatural strength. Mark felt his throat tighten, anguish threatening to overwhelm him.

“I’m getting you out of here,” Mark insisted, looping an arm under Yates to drag him. He refused to leave another man behind. But Yates began to scream, thrashing wildly. His screams were inhuman, gurgling on the edge of speech as if another voice echoed from within. “It’s in my blood! Get it out!” he howled. He slammed his head back against the bulkhead with a sickening thud, trying perhaps to knock himself unconscious.

Mark grappled with him, terrified. In the dim light Yates’s face was warping, cheeks bulging oddly as if something writhed beneath the skin. His left arm – the one that had been burned – jerked and spasmed, and to Mark’s horror the limb snapped at the elbow with a loud crack. Yates didn’t even seem to feel it; his whole body was contorting. Mark saw the flesh of the broken arm begin to… move. The skin rippled as though alive with its own will. Something slick and rope-like squirmed just under the surface, stretching, lengthening the arm obscenely. The outline of sucker-like discs pushed up beneath Yates’s skin, as if a tentacle was growing out from within his arm.

Mark’s courage finally faltered – this was a nightmare beyond anything he’d ever trained for. “Jonah…?” he whispered, voice trembling. But Yates was beyond hearing. With a final convulsive jerk, Yates lurched forward and bit at Mark, teeth snapping inches from Mark’s face. Mark recoiled in shock, losing his grip. Yates – or the thing Yates was becoming – scuttled on hands and knees with disturbing agility, then collapsed again, twitching. His body was remolding itself like clay, bones cracking. A wet, burbling moan rose from his throat, no longer sounding human.

Tears of rage and revulsion stung Mark’s eyes. He staggered upright. There was no time to think – the man in front of him was already lost, transformed into something monstrous by the creature’s foul blood. Mark drew the service pistol from the holster on his hip – he hadn’t even remembered grabbing it from Nguyen, but there it was, heavy and cold in his hand. Yates’s head jerked up at the movement, his eyes now fully glazed over in milky blue. With a guttural hiss, the thing that had been Jonah Yates flung itself toward Mark one last time, lunging.

Bang! Mark fired. The crack of the gunshot was deafening in the corridor. The bullet caught Yates squarely in the chest. The ensign froze in place, a look of almost relief passing over his ruined face. Then he slumped backwards and went still, half-submerged in the puddle of seawater and blood on the deck. The echoes of the gunshot faded into ringing silence.

Mark stood there trembling, gun smoking in hand, staring at Yates’s corpse. My God… I just… I just shot… He couldn’t even finish the thought. But it had not been Jonah anymore – Mark told himself that firmly, clinging to sanity. He had spared the young man from a fate worse than death. Still, the horror of it carved a ragged hole in Mark’s chest. In less than fifteen minutes, his submarine had become a charnel house. So many of his crew – friends, colleagues – dead or transformed into nightmares. How could this be happening?

A heavy boom reverberated from the direction of engineering, as if to punctuate the thought. The creature was still battering at the barriers somewhere behind Mark, reminding him the fight wasn’t over. Mark wiped a sleeve across his face, realized he was drenched in sweat – or maybe tears – and forced himself to move. He retrieved the fallen radio from Yates’s belt with numb fingers and switched it to the emergency frequency.

“This is Lt. Commander Davis of the Reliant,” he spoke hoarsely, pressing the transmit button. “Mayday, mayday. We have an intruder… hostile entity on board… They’re inside. Repeat: hostile inside.” Only static answered. Mark cursed under his breath. The earlier power surges or that EMP-like whine must have knocked out communications.

In the distance, a new sound started to rise over the dying echoes of the last impact. It was the groan of twisting metal – the Reliant’s hull protesting against increasing water pressure. Mark’s gut lurched. Was the sub sinking? Perhaps with the engine room flooded and controls offline, they were drifting downward into the depths. If they went too deep…

Mark banished that thought. One catastrophe at a time. He still had crew left alive in other sections, and a monster loose behind him. He had to get to the control room, see if the captain or anyone could still steer the boat or call for help. Holstering the pistol in a death grip, Mark turned and ran down the corridor, boots splashing through blood-tinged water. The red emergency lights flickered overhead as he went, casting a hellish strobe along the narrow passage. The submarine felt eerily quiet now aside from the distant hull noises – the alarm klaxons had shorted out, and in their absence a heavy, claustrophobic hush fell.

Mark’s own ragged breathing and footfalls were his only companions as he navigated the tight passageway. Pipes overhead dripped. Once, he nearly slipped on something slick – a smear of blood from another fallen crewman who had been dragged out of sight. Mark stepped over the outstretched arm of a corpse half-submerged in the corridor; he forced himself not to look too closely at the face. Keep moving.

He reached a hatch leading toward the central control. It was partially jammed, and he had to shoulder it open. As he did, a wave of dizziness washed over him. The edges of his vision danced again with those impossible shapes – the walls seemed to elongate, the floor tilting oddly. Mark paused, pressing a hand to his temple. He felt a slight tremor in his skull, almost like a distant whisper of static deep in his brain. The creature’s telepathic presence? Or just the neurotoxin still burning on his sleeve affecting him? He shook it off and pressed forward.

The control room was just ahead—he could see its doorway—but as Mark stepped into the junction, a sudden power fluctuation rolled through the submarine. The lights blinked out entirely, plunging everything into absolute black. Mark froze in place. In the darkness, the silence was total. He could hear his own heartbeat thudding in his ears. Then, faintly, a sound reached him.

It came from somewhere behind, muffled by layers of steel: the screech of twisting metal and a splash, as if a sealed hatch had finally given way. Mark’s blood turned to ice. The creature… perhaps it had found another route, or broken through into an adjacent compartment. Either way, the implication was clear – the c’thalhai was no longer contained. It was on the move again inside the sub. And now Mark was enveloped in darkness with it.

His hand fumbled for the flashlight on his belt before remembering he’d lost it. Swearing under his breath, Mark unlatched a chem light from a wall socket – one of those glowsticks for emergency lighting – and cracked it. A dim green glow illuminated the passage just enough to see a few feet. The emergency power struggled back to life a moment later; the red lights flickered on to a low, barely functioning level. It was scant illumination, but it gave the dripping corridor an even more hellish hue.

Mark advanced slowly now, every sense straining. He was close to central control, but he didn’t dare rush and stumble blindly into the creature if it had circled around. The hair on his neck prickled; he could feel something in the stale air, a predatory aura closing in. He crept along, one hand trailing the wall. The passage was littered with debris – a fallen pipe here, a dropped clipboard there. The Reliant was wounded, systems failing one by one. A low thrumming sound began to build – perhaps the emergency pumps finally kicking in to slow the flooding, or the distant hum of the reactor with unstable voltage. Every noise set Mark’s teeth on edge.

He turned a corner into the last corridor leading to the control room and stopped short. The sight before him was pure nightmare. The hallway was slick with blood and seawater, the mixture sloshing around his boots. Dark handprints smeared the walls where crew had fought or been dragged. A lone fluorescent bulb dangled from the ceiling, sparking and casting wild flashes of light and shadow. Bodies lay strewn along the passage – two, three, Mark couldn’t tell in the poor light. One figure in a navy uniform slumped against the bulkhead, head lolled at an impossible angle. Another half-floated in a pool of water, a trail of intestines unspooling from a gash in his belly. Mark had to choke back bile. He stepped forward gingerly, heart in his throat. He recognized one of the fallen – the radio operator who had been on duty, now lifeless eyes staring up in horror. There was no sign of what killed them; the creature must have passed through here during the chaos, leaving devastation in its wake.

The corridor ahead ended at a thick bulkhead door leading into central control. The door was ajar, its reinforced glass window cracked. Beyond it, Mark could see the faint glow of instrumentation. Perhaps some of the bridge crew were still there, barricaded inside. Mark felt a surge of desperate hope. He started forward, wading through the carnage. His hand was outstretched to push open the door when a shadow moved in his peripheral vision.

Mark froze and instinctively flattened against the wall, extinguishing his chem light under one hand. Several yards back down the corridor, past the blinking bulb and the heap of corpses, something slithered across the intersection. It was just at the edge of sight – a sinuous, gliding form slipping from one side of the hallway to the other, visible only for a heartbeat in the stuttering light. In that brief flash, Mark saw a long, rubbery limb pull silently through the blood-slick water, leaving ripples that made the crimson puddles dance. Then it was gone, vanished into an adjoining compartment or crawlspace.

Mark’s breath caught in his chest. It was here, only meters away. The creature had doubled back to stalk him, or perhaps to guard its trapped prey. He remained absolutely still, pressed to the wall, unwilling to even blink. His eyes locked on the broken glass window in the bulkhead door ahead. It was reflective enough to faintly show the corridor behind him. He watched that reflection now, his own dim silhouette outlined in red… and behind it, just beyond the doorway he’d come through, he saw another shape.

Slowly, almost casually, a tangle of appendages entered the corridor, one after another, dragging a bulbous bulk behind them. The c’thalhai’s form unfurled in the flicker of the lone bulb. It moved with eerie silence, liquid grace despite its size. Mark could hear nothing but the throb of his own pulse, but in the mirror-like glass he saw the creature pause, as if tasting the air. Was it aware of him? Or was it following some primal patrol of its newly claimed territory?

Mark’s finger crept to the trigger of his holstered pistol. The weight of the three remaining bullets felt feeble compared to the enormity of the threat. If it sensed him now, he’d have to make a final stand. He drew the weapon as quietly as he could, keeping it low.

In the reflection, the c’thalhai resumed its glide forward. As it passed one body, a tentacle darted out to idly probe the open wound, scooping up a chunk of bloody tissue. Mark’s stomach churned as the arm delivered the morsel to the creature’s beaked maw. It was feeding. Consuming his crew like a buffet. Hot anger momentarily eclipsed his fear – but he forced himself not to move. Not yet. If he fired now, in close quarters, and failed to kill it, he’d only give away his exact position. And then there would be no saving anyone.

Slowly, the creature slunk nearer, making its way past each corpse, inspecting, searching. It was coming his way. Mark’s grip tightened on the pistol. Sweat trickled down his brow. The creature’s hide glistened with a mixture of seawater and gore, patches of its skin flashing camouflaged colors that matched the dank surrounding – one second it blended nearly invisible against the dark wall, the next a ripple of blue bioluminescence coursed along its mantle, as if excited by the feast. Each pulse of that ghostly blue glow illuminated the corridor, giving Mark stroboscopic glimpses of the horror creeping toward him.

At last, the c’thalhai neared the bulkhead door where Mark hid. Only the partial cover of the doorframe and shadow kept him from its direct line of sight. Mark swallowed, finger on the trigger, preparing to shoot the eye when it rounded the corner…

Without warning, a shrill clang echoed from deeper inside the control room – some piece of equipment shorting out. The creature halted, tentacles coiling, and snapped its head around toward the sound. In that split second, Mark acted on impulse. He lunged the final step to the bulkhead door and slipped through it into central control, pulling it shut behind him. He spun the lock wheel quietly until it clicked. Now only a few inches of steel separated him from the monster.

Mark stumbled backward into the control room, which was eerily empty save for the corpse of one officer sprawled over a console. The instruments flickered with low power, casting a faint glow. He realized with a mix of relief and despair that the bridge crew must have evacuated – perhaps to the torpedo room or escape pods. He was alone here. Alone except for…

A heavy thud rattled the bulkhead door. Mark’s eyes snapped to the small reinforced window set in it. Screeeeech… A slimy tentacle slid across the glass from outside, smearing it with viscous blue slime. Mark’s breath hitched. Slowly, he edged toward the door, drawn by grim fascination and dread. Through the gore-smeared pane he could just barely make out the corridor, lit by the erratic flash of that single dying bulb. A dark shape loomed there – the c’thalhai’s massive body blocking most of the view.

It was right on the other side. Mark held his gun at the ready, aimed at the window, but the creature didn’t immediately try to break through. Instead, something small bumped against the glass from outside. Mark squinted. It was the tip of one of its appendages, nudging at the window almost playfully. The end of the tentacle peeled open, revealing a ridged pad of suckers that suctioned onto the glass with a wet pop. The glass creaked under the strain as the tentacle slowly dragged across it, the suckers making a hideous schlorp sound as they detached and reattached, inch by inch.

Mark fought down a surge of nausea. The bulkhead door was one of the sturdiest on the boat – reinforced to protect the command center – but after everything he’d seen, he wasn’t confident it could truly keep this thing out. He took another step back, gaze locked on that window.

Then, suddenly, the creature’s eye slid into view, pressed almost gently against the pane. Mark’s heart jolted. It was the size of a softball, iris a nightmarish swirl of black and deep-sea blue. It rolled its pupil around, scanning the control room through the glass. Mark realized it could likely see him standing just a few feet away. He stood transfixed, pistol shaking in his hand but momentarily forgotten. On the other side of that two-inch window, an ancient, inhuman intellect was studying him like a specimen. Mark felt a cold wave of helplessness; in that unblinking stare he sensed not just hunger, but an alien curiosity. As if the creature were deciding what to do with him.

A low rumble emanated from beyond the door – a series of clicking pulses. The eye withdrew, and a second later the tentacle unlatched from the window with a wet smack. Mark exhaled, not realizing he’d been holding his breath. The silhouette of the c’thalhai drifted back a pace, its form indistinct through the slimed glass.

All at once, the creature’s arm whipped across the window. CRACK! The reinforced glass shattered into a spiderweb of fractures but held. Mark staggered back, raising his gun again. Another blow came – BAM! – denting the metal and sending a web of cracks through the porthole’s center. One more like that and it might break through. Mark braced himself, finger on the trigger, ready to unload every remaining round when it tried.

But then, just as quickly, the assault stopped. The silhouette moved away from the door. Mark heard a scraping sound, a splash, then silence. He crept a step forward, straining to see through the crazed glass. Red light from the corridor filtered in faintly. Nothing moved out there. The creature was gone.

Mark stood in the flickering emptiness of the control room, bloodied, burnt, half-deafened, entirely exhausted. The only sound was the labored thrum of the auxiliary generator and his own ragged breath. Had it truly left? Or was this another trap, the calm before the killing stroke? He checked the pistol – three bullets – and licked his dry lips.

Slowly, he leaned closer to the cracked bulkhead window, peering out one fractured segment that wasn’t fully opaque. The corridor beyond stretched away in a red blur. No sign of the creature. Perhaps it had retreated to lick its wounds or find another ingress. Mark’s shoulders sagged in spite of himself. It was only then he realized he was quietly sobbing – tears of frustration, rage and grief mingling on his grime-streaked face. He swiped them away angrily. Not dead yet. Get it together.

As he pressed his forehead to the cool glass, something moved in his peripheral vision. Down the hall, near the far junction, a portion of shadow detached and slithered across the floor. Mark’s breath caught. In the gloom he saw it: the c’thalhai, now crawling along the corridor outside the control room. It was partially up on the wall, its body elongated and stretching into the adjacent compartment doorway like a giant hellish squid creeping through a reef. In the flicker of failing light, Mark glimpsed one of its eyes peering back toward him, shining with that malevolent intelligence. A shudder passed through him.

The creature paused by the pile of corpses it had made… and then, almost mockingly, it raised one gruesome arm – still coiled around Nguyen’s lifeless body – and dragged its prize leisurely down the hall, away from Mark’s view. It was leaving, slipping back into the bowels of the Reliant with the remains of its victims, as a spider might retreat to savor a catch. Mark watched in cold dread as the last tip of a tentacle disappeared around the distant corner. Only a smeared trail of blood and the intermittent flicker of lights proved it had ever been there at all.

For a long moment, Mark remained rooted to the spot, eyes fixed on the empty corridor through the fractured glass. His legs trembled under him, adrenaline fading to be replaced by pure horror at the memory of what he’d just witnessed. In the silence, the submarine’s structure groaned again – a haunting wail as if the ship’s very soul cried out. Lights continued to dim and systems died one by one, but Mark barely noticed. All he could see in his mind was that inhuman silhouette slithering away, somewhere still inside his ship.

He was alive, yes. But the nightmare was far from over. Somewhere in the blood-slick corridors beyond, something inhuman was still lurking, and he had no idea when it might return. Mark drew a shuddering breath and tightened his grip on the pistol. In the battered reflection of the control room glass, lit by faltering red light, he looked like a ghost – a gaunt, wide-eyed specter drenched in blood and seawater.

Jaw clenched, Lt. Cmdr. Mark Davis steadied himself and began limping toward the rear hatch of the control room, determined to find any survivors and rally a last stand. The taste of coppery blood and acid lingered in the air. Behind him, through the cracked window of the bulkhead, the corridor lights flickered and went dark, as if the Reliant herself was closing her eyes against the unspeakable horror that slithered in her veins.

New Liscannor Deep-Sea Research Outpost – Signals in the Deep

Dr. Priya Das flipped the page of the printout with trembling fingers, her dark eyes darting over lines of indecipherable data. A single desk lamp lit her cramped lab station in the New Liscannor Deep-Sea Research Outpost, casting her face in a soft amber glow against the predawn gloom. Outside the reinforced viewport to her left, the Atlantic waves pounded the rocky coast relentlessly, but inside the outpost’s concrete walls all was hushed – an uneasy quiet broken only by the hum of machines and the scribble of Priya’s pen.

She ran a hand through her thick black hair, trying to ignore the knot of anxiety twisting in her stomach. Spread across the desk were maps of the North Atlantic trench system, reams of seismic readouts, and spectrograms of audio recordings. For the third time that night, Priya found herself double-checking the figures from the oceanic buoys. This can’t be right, she thought for the hundredth time. Yet there it was in plain ink: a pattern, subtle but undeniable, emerging from what should have been random background noise.

Priya chewed her lower lip, a childhood habit that often surfaced when she was deep in thought. She had grown up chasing patterns. As a girl in Mumbai, she’d sit on the balcony during monsoon storms, mapping out the rhythm of raindrops, convinced there was hidden meaning in their patter. That inquisitiveness – some would say obsession – had carried her from the Indian Institute of Technology to a doctorate in marine biology and acoustic ecology. Eventually it led her across the world to this remote Atlantic research outpost on the Irish coast, far from home but closer than ever to the ocean’s mysteries. New Liscannor was small – just a handful of scientists and technicians – but it boasted advanced sensors monitoring the depths. Priya had jumped at the chance to work here, to listen to the whispers of the abyssal deep. She never imagined those whispers would turn into screams.

Tonight, the ocean was speaking in a code she’d never encountered. It had begun two days ago. One of the outpost’s sonar buoys picked up an anomalous sound: a series of low-frequency pulses reverberating up from the abyssal trench off the continental shelf. The pattern was faint but regular – almost like a heartbeat echoing up through miles of water. At first, Priya suspected a faulty hydrophone or perhaps a whale’s call distorted by unusual currents. But then a second buoy, fifty kilometers north, registered the same pattern half an hour later. A third buoy to the south chimed in after another interval. It was as if something massive was moving along the ocean floor, triggering sensors in a deliberate sequence.

“Priya? You still at it?” a gentle voice cut through the quiet. She startled slightly and looked up to see Luis Alvarez, the outpost’s systems engineer, standing at the lab doorway. He offered a tired smile. “It’s nearly four in the morning. Even you need some rest.”

Priya managed a distracted smile back. Luis was in his early fifties, with kind eyes and a perpetual scent of coffee about him. He had become a sort of surrogate older brother to Priya during her tenure here, often gently reminding her to eat or sleep when she got too absorbed in work. “I know, I know,” she sighed, rubbing her eyes beneath her glasses. “But this data… it’s just not adding up to anything natural.” She tapped the printout. “I can’t shake the feeling we’re looking at something intelligently organized.”

Luis raised a graying eyebrow and stepped in, cradling a steaming mug. “Organized? You mean like… artificial?” He handed her the mug. It was chai – her favorite. Priya accepted it gratefully, inhaling the cardamom-scented steam as a small comfort. She gestured to the map pinned on the corkboard. Red circles marked the buoy locations that had recorded the anomalies. “It’s like a lattice,” she explained. “If you plot the timing and location of each event, they form a lattice-like grid pattern across the trench region.” She drew an invisible grid over the map with her finger. “Perfectly spaced, almost like… like an array of signals or movements coordinating with each other.”

Luis frowned, leaning in to peer at the map. “Could it be some kind of geological survey equipment malfunction? Maybe the array is glitching?”

Priya shook her head. “These buoys are independent of each other. There’s no central computer that could glitch in that way. And look—” She shuffled through the papers and pulled out a black-and-white sonar image with several plotted curves. “This is from earlier today when we sent the rover drone down to collect samples after the third anomaly.”

The image showed the dark contour of the trench and, near the bottom, multiple heat signatures in a clustered formation. “We thought it might be volcanic vents flaring up,” Priya said. “But the thermal pattern wasn’t diffuse like an eruption. It was focused, circular pockets of heat. Five of them. Arranged almost… symmetrically.”

Luis’s eyes widened as he took in the formation. “It does look symmetric. Like five points on a huge circle or something.”

“Exactly.” Priya sipped her chai, wishing it could wash away the dread gathering in her throat. “Nature can produce symmetry, sure – like crystalline structures, radiolaria patterns, etc. But five identical heat blooms spaced so evenly? And the seismic pulses traveling in a neat sequence corresponding to their positions? It’s too much of a coincidence.”

Luis ran a hand through his salt-and-pepper hair. “So you’re suggesting what? That someone – or something – is down there, moving in a coordinated way? In the trench? That trench is seven miles deep at least… nothing human could be operating at that depth. Not for this long, not in such a wide area.”

Priya didn’t answer immediately. She set the mug down and turned to a refrigerated case against the wall. Inside was a small vial of seawater sample collected by the rover drone. “If not human, then… biological,” she said softly. She retrieved the vial and held it up. Under the fluorescent lab light, the water inside had a faint bluish tinge. At the bottom, settled silt and tiny particles glittered. “This is what the drone found near one of those heat spots. At first glance, just ordinary deep-sea sediment. But it’s not.”

She slid the vial under a digital microscope and beckoned Luis over to the monitor. Grainy magnified shapes came into focus – minute particles suspended in water, many irregular specks of sediment… but also something else. A few filamentous strands floated among the debris, thin and translucent blue.

Luis squinted. “Fibers? Or some kind of plankton?”

Priya clicked to enhance the contrast. The strands had an almost organic structure, like fine cilia or perhaps fungal mycelium. “Not sure. They’re not any plankton I recognize. I ran a quick assay – it showed traces of complex proteins, maybe even nucleotides, but nothing conclusive. Could be some deep-sea organism we haven’t catalogued.”

“Blue fibers… and blue water,” Luis mused, tapping the vial. “Could tie to that blue algae bloom we had on the shoreline last week.”

Priya nodded slowly. Last week, local fishermen had reported unusual blue-tinged water and dead fish washing up near the outpost’s cove. Priya had analyzed some of those fish – they’d shown signs of corrosive burns, as if exposed to acid, and trace amounts of an unknown toxin. At the time, she thought it might be illegal dumping of chemicals or perhaps a weird algal toxin. But now… could it be related? Blue-tinted, corrosive, biological. She made a mental note to cross-reference the toxin in those fish with these new samples.

Before she could share that thought, the overhead lights flickered. The computer monitor dipped to black, then came back. Across the lab, an array of instruments blinked red as power fluctuated. Luis cursed under his breath. “Not again… The generator’s been acting up all week.”

Priya’s stomach clenched. This was the third power blip tonight. “Check the mains, I’ll save everything here,” she said, already moving to hit the save command on her data logs. Luis hurried out toward the control hub down the hall, keys jangling at his belt.

The lights dimmed once more, then stabilized. Priya exhaled, tension thrumming in her veins. A moment later Luis’s voice came via intercom: “Priya, the grid’s fine. That looked like an external surge – maybe an electromagnetic pulse? We might’ve had a lightning strike nearby.”

She frowned and glanced at the weather readout on her console. Clear skies, no storms. And an EMP-like surge… this remote outpost wasn’t near any powerful transmitters, nor were there military exercises scheduled. A creeping unease settled over her. First anomalous signals, now mysterious surges disabling equipment. It’s almost like someone’s jamming us, she thought. But who would jam a scientific outpost?

Her musings were cut short by a soft beeping from one of the acoustic receivers. It was a proximity alert – one of the deep-sea buoys had detected a strong signal nearby. Priya’s head snapped to the display. A live spectrogram tracing across the screen showed an intense low-frequency rumble, far louder than anything previous. It was as if the ocean floor itself were roaring.

She rushed to put on a pair of headphones and tuned into the hydrophone feed. At first all she heard was static and the normal background noise of the sea – distant whale song, the crackle of shrimp. Then it came: a deep, resonant thrumming, like the tolling of a gigantic underwater bell. It pulsed rhythmically, and layered atop that sound was another noise that made Priya’s skin crawl – a series of clicking chirps, rapid and complex, almost like a code. It was language, she realized with astonishment. No natural geological process produced patterned clicks. This sounded more like communication. Intelligence.

She ripped the headphones off and sprinted to the outpost’s central ops room where Luis was already scanning the panels. A couple of other team members, bleary-eyed from sleep, had joined him, alarmed by the power flicker. Jae, the communications specialist, was fiddling with the radar. Marisol, the intern who handled data entry, stood clutching a notepad, looking nervous.

“Luis, are you seeing this?” Priya blurted, pushing past to the main console and pulling up the live buoy feed. The others crowded around as the graph spiked into red. “Buoy 7 just logged a massive reading—”

Before she could finish, the whole facility shuddered. It was subtle, but unmistakable – a vibration running through the floor as if a minor earthquake had struck offshore. A low rumble followed, and one of the hanging LED lamps swung gently. Marisol yelped, grabbing onto a filing cabinet for balance.

“That felt like a shockwave,” Jae said, eyes wide. He adjusted his headset, trying to hail their sister station down the coast. “I’m checking if they felt that too.”

Priya’s mind raced. A shockwave now, of all times? Could something have happened in the trench? An underwater landslide? But the patterns, the signals… it felt more directed than mere coincidence. She keyed into the seismic feed. Sure enough, local seismographs were spiking. Not a natural quake signature though – it was too brief, too sharp. An explosion? Her gut told her otherwise: something down there had moved. Perhaps something big.

Luis was at the generator control, muttering about input overloads. “We’re getting another surge! What on earth…?” he exclaimed. Priya looked over his shoulder. The incoming power readings were fluctuating wildly, as if bombarded by a strong electromagnetic field. The lights began to flicker erratically in tandem. One of the computer monitors popped with a shower of sparks, making Marisol scream.

“Shut the systems down, now!” Priya shouted. If it was an EMP or similar phenomenon, they needed to safeguard what they could. Luis hit the emergency cutoff. The main lights died, and the outpost was plunged into semi-darkness, lit only by the red glow of battery-powered emergency strips along the floor. The lab equipment powered off, and the constant background hum of ventilation quieted, leaving an eerie silence.

Everyone held their breath, listening. Priya’s ears rang in the sudden quiet. Far off, carried through the rock and water, she could faintly hear that deep thrumming sound continue… or was she imagining it? It almost resonated in her chest, a physical vibration.

“Backup generator will kick in soon,” Luis whispered. In the dim red glow, Priya saw sweat on his brow. “We need to see what’s happening out there.”

Jae tapped a portable tablet he’d grabbed. “I’ve got the buoy telemetry here on backup battery. Holy…” He tilted the screen toward Priya. The temperature readings in the trench were spiking dramatically, as if a vast upwelling of warmer water were rising. And the depth gauge on buoy 7 – which sat at 3000 meters – was showing a rapidly decreasing number. 2950… 2900… 2800… “Is the buoy rising?” Jae said in confusion.

Priya realized what it meant and her mouth went dry. “No,” she said, voice barely above a whisper. “The buoy’s static. It’s anchored. Something is coming up from below it.” She traced the numbers with a trembling finger. In just the past minute, something had ascended a full two hundred meters. And accelerating.

Luis swore softly in Spanish, crossing himself. Marisol had begun quietly crying, fear evident on her face. Priya’s mind swirled. Could it be an undersea vehicle? Some kind of experiment from another nation? But nothing human moves like that, not at those depths and speeds. And that wouldn’t explain the code-like clicks, the EMP bursts…

Unless… unless the signals themselves had been creatures. Hyper-intelligent creatures coordinating movement, using low-frequency sound or electromagnetic pulses to communicate. Her earlier wild theory about an intelligent presence in the trench no longer seemed far-fetched – it was the only explanation left standing. The c’thalhai – the old fisherman tales, the half-joking references to sea monsters – came crashing into her mind. This was their domain, after all, the deep ocean. Had humanity been arrogant to assume nothing down there could challenge us?

Her heart thundered against her ribs. “We need to alert the mainland,” Priya said urgently, grabbing Jae by the arm. “The naval base, coastal emergency services – everyone.”

Jae nodded and pulled out the satellite phone – their failsafe for communication when internet and radio failed. He punched in the line to Fort Armitage base command, but shook his head. “No signal… The EMP might’ve fried the antenna, or something’s jamming even sat comms.”

A feeling of isolation wrapped around them. No help was coming right now. It was just the handful of them in this outpost, perched on the edge of a sea that suddenly felt crushingly malevolent. Priya realized her hands were shaking. She’d dedicated her life to studying marine life, seeking understanding. But at this moment, feeling the rumble of something giant and alive ascending through the dark waters, she was simply afraid.

“I’m going outside,” Luis announced, snapping Priya out of her thoughts. He crossed to the heavy steel door that led to the external observation deck. Through its porthole window, predawn darkness loomed. “Maybe we can see anything with the high-beam.”

Priya hurried after him. “Careful, the winds—”

But Luis had already cracked the door, and a gust of cold, salty air whooshed in, carrying the sound of crashing waves. The observation deck jutted from the cliffside, giving a panoramic view of the Atlantic expanse. Priya followed him out, squinting. The sky was still starless black on the western horizon, with a faint glow hinting at dawn to the east. The ocean spread out like an endless void, subtle whitecaps glinting when the waves hit the rocks below.

Luis flipped on the deck’s high-beam searchlight, sweeping it over the water. The beam cut a brilliant arc across the darkness, illuminating the froth of the surf far below and scanning outward over the churning sea. At first, there was nothing to see – just the restless Atlantic, deep and inscrutable. But then Priya’s eyes caught a glimpse of something out beyond the surf, perhaps a hundred meters from shore. The water’s surface looked… different. Disturbed. The beam passed over it too quickly to tell, so she grabbed Luis’s arm. “Go back,” she urged, pointing.

He panned back, and there – the beam reflected off a patch of ocean that swirled in a bizarre concentric circle, as if a whirlpool was forming from below. The center of the patch bulged slightly, water cresting upward into a mound. Priya’s breath hitched. No, not possible… It was as if something was displacing an enormous volume of water from beneath, rising toward the surface.

“Marisol, get the camera!” Priya yelled back into the door. Marisol, who had followed a few steps out, rushed back inside for the digital camera gear. Jae stepped out onto the deck in awe, phone in hand now recording video shakily.

The rumbling was definitely audible out here – a deep bass thrumming that Priya could feel in her bones. The water bulge grew, swirling faster. The ocean around it heaved unnaturally. And then, with shocking speed, the mound rose higher – a dome of water maybe ten or fifteen meters across, pushed up from below as though by the snout of a surfacing whale… except no whale was that large or made the ocean boil like this. Foam churned at the edges of the upwelling.

“There’s something coming up!” Luis shouted, competing with the roar of waves.

Priya clutched the metal railing, knuckles white. Half in a trance, she realized she was mumbling a prayer in Hindi – an old habit from childhood she hadn’t done in years. Her instincts understood before her brain fully did: this was not just an anomaly, it was a surfacing. The anomalies had converged, and now whatever intelligence lurked in the trench was announcing itself.

Suddenly, an intense blue light glowed from beneath the swell. It pulsated once, twice – enormous and otherworldly, casting rippling azure beams through the water. Priya’s eyes widened. Bioluminescence? The glow was far too large and bright to be a single organism like a jellyfish. It had to be many working in unison, or one unimaginably huge entity. The lattice… the coordinated signals… They weren’t just moving together, they were converging into one formation. Perhaps into one colossal being, or an army surfacing as one.

With a final violent surge, the ocean surface broke. What erupted forth defied comprehension at first. Through the cascade of water and foam, Priya glimpsed towering appendages – massive, glistening tentacles unfurling into the cool night air, water streaming from them in waterfalls. More blue lights ignited along those limbs in pulsing stripes. A shape – vaguely cylindrical and the size of a building – began to emerge beneath the thrashing arms, covered in black, chitinous plating and glowing runic patterns of phosphorescence. The sound that came with it was a bone-rattling bellow, a deep roar interlaced with a high-frequency shriek that made every hair on Priya’s body stand on end. Even from this distance, the sheer volume of the cry was staggering; the metal platform vibrated with it.

Marisol had returned with the camera just in time to see this sight. She dropped it with a clatter, gawking and letting out a strangled sob of terror. Jae’s phone was still raised, but he was cursing loudly, backing away toward the door. “What the hell is that?!” he screamed.

Priya couldn’t answer. Words failed. Her rational mind reeled, cataloguing impossible details: one of the colossal tentacles had to be at least twenty meters long, ending in a claw-like structure that crackled with bluish sparks – perhaps organelles generating electromagnetic fields. Portions of the creature’s rising body were studded with glowing, lidless eyes bigger than dinner plates, each casting an eerie gaze in all directions. The water around it frothed with smaller shapes as well – countless smaller tentacled creatures swarming around the leviathan, like spawn answering a mother’s call.

In a flash of absurd clarity, Priya thought of the mythical Kraken… and felt a chill as she realized that human myth barely scratched the truth of what lay beneath the waves. This was not a mere giant squid or octopus. This was C’thalhai – it had to be, the ancient enemy stirring from the trench. And it wasn’t alone. It was rising with an army.

The creature let out another reverberating call, and as if in response, the outpost was struck by a blast of energy. The entire deck shuddered; sparks exploded from the high-beam light, plunging the scene into semi-darkness again. Priya stumbled as all around them electronics blew out in a cascade of popping lights. The mysterious EMP surge had returned at full force, likely triggered by the rising behemoth’s presence. The emergency strip lights burst, and the outpost fell dark save for the ghastly blue glow emanating from the nightmare in the sea.

“Inside! Get inside now!” Luis roared, grabbing Marisol who was paralyzed in fear. He dragged her bodily through the door as a gale of wind and salt spray burst over the deck. Jae had already fled in, and Priya was last, unable to tear her eyes from the monstrous sight in the water even as tears of dread ran down her face. The thing was fully surfaced now up to maybe a third of its bulk, bobbing amidst the waves like an island of flesh and wrath. She could see dozens of smaller shapes – perhaps still huge in their own right – writhing around it, some crawling onto its main body, others diving back under. The impossible reality of it threatened to overwhelm her sanity.

With a final effort of will, Priya forced herself back into motion and stumbled inside, slamming the heavy steel door shut behind her. She threw the deadbolt and stumbled back, chest heaving. The others were gathered in the darkness of the ops room, faces lit occasionally by the flicker of dying monitors. Marisol was praying under her breath in Spanish, clinging to Luis. Jae sank into a chair, the glow of his phone on his face showing utter shock.

Priya joined them, and they huddled together in the pitch-black control center. Outside, through the thick concrete, they could still hear the distant roars of the rising horror and the crash of now-turbulent waves. The outpost lights were gone, communications cut – they were blind and mute, perched on the precipice of an unfolding cataclysm.

In the dark, Luis’s voice trembled as he asked, “Priya… what do we do?”

Priya inhaled shakily, wiping rain and tears from her face. Her mind raced. They had a satellite uplink backup in a Faraday cage for extreme emergencies. If it still worked, maybe they could send a short distress burst. Or they could try to reach the mainland by driving – but the only road was a cliffside path which the creature could easily flood or block if it came closer. There was an emergency bunker built into the rock… but would that even help if the ocean itself rose?

Before she could answer, another faint tremor shook the floor. Priya realized the monstrous calls had ceased. An eerie silence fell outside now, more frightening than the noise. Perhaps the creature had submerged again or was moving away from the immediate coast. But where would it go?

She recalled the lattice of signals. They’d been moving… and converging. Maybe this was just one point of emergence. What if others were rising along the Atlantic? The thought made her blood run cold. It wasn’t an isolated incident; it was an invasion already in motion.

“First,” Priya finally whispered, voice shaking but resolute, “we warn everyone we can. Even if it’s just one message out… we have to try.” She fumbled her way to the emergency comms locker, Luis following with a penlight. They began unsealing the case containing the backup beacon. Priya’s fingers were steadier now that she had a purpose. “Then… then we pray and prepare. We gather whatever provisions and data we can and get to higher ground. If this outpost is compromised, we might have to evacuate inland.”

Jae nodded, regaining some composure. “I got a few seconds of video. It uploaded to cloud just before everything died, I think,” he said. “People will see that… they’ll have to believe it.”

Priya hoped he was right. She keyed the beacon to life; a tiny red LED blinked, searching for a satellite link. For a tense half minute it struggled, then went green. A connection. With hurried breaths, Priya tapped out a brief coded SOS message to any nearby station: “Deep-sea entities rising from trench. Coastal attack imminent. Notify military.” She hit send. The beacon flashed, transmitting into the void.

Whether anyone would heed it in time, she had no idea. But at least she’d sent out a warning cry of her own. Her duty, as a scientist and as a human being, compelled her to share what she’d seen, as terrifying as it was.

As the team quietly mobilized – gathering hard drives, a first aid kit, emergency flares – Priya stood for a moment by the dark window. She could no longer see the ocean from here, only her own faint reflection. She was trembling head to toe, reality crashing in: They’re real. The c’thalhai are real, and awake, and moving. A part of her refused to accept it, but the scientist in her coldly catalogued the evidence. The pattern, the signals, the mutated samples, and now the visceral sight of a leviathan rising. The pieces fit an awful puzzle.

She thought of her family back home, of all the coastal cities and towns sleeping unaware this night. If these creatures meant to wage war, humanity was woefully unprepared. Massive… coordinated… intelligent. The words from her notes echoed in her mind. She felt a surge of both dread and determination. She would find a way to help stop this – to understand them, find a weakness, something. It was what she had trained her whole life for, in a way, though never in her wildest nightmares had she imagined such an enemy.

Behind her, Luis gently touched her shoulder, snapping her back. “Priya, we’re set. Let’s move.” In the faint red glow of a battery lantern, she saw fear in all their eyes… but also trust in her leadership. She gave a firm nod, swallowing her own fear.

As they made their way to the exit that led up the hill behind the outpost, Priya cast one last glance at the lab equipment, the charts, the data she was leaving behind. A single thought flared in her mind with stark clarity: Something massive is rising from the trench, and the world is about to change forever.

She only wished with all her heart that humanity would survive the revelation.

Back on the USS Reliant – Blood in the Water

A strobe of emergency light flickered through the smoke-choked corridor of the crippled Reliant, painting the walls in alternating hues of crimson and shadow. Lt. Cmdr. Mark Davis limped forward, one hand braced against the slick bulkhead to keep from collapsing. The taste of blood and salt was thick on his tongue. Around him, the submarine was eerily quiet now, save for the distant trickle of water seeping through unseen cracks and the sputter of sparking wires dangling from the ceiling.

Mark’s path was illuminated sporadically by the dying lights, revealing a scene from hell. The once-clean steel corridors were streaked with gore. Dark red blood – human blood – mingled with patches of glowing blue slime that ate into the metal wherever it pooled. The acidic fluid had dripped from the creature’s wounds and now etched grotesque patterns into the deck and walls, as if the ship itself were suffering chemical burns.

Stepping over the torn remnants of a bulkhead panel, Mark nearly lost his footing. He glanced down and felt his stomach lurch. The deck was slick with a film of blood. A severed boot – foot still inside – floated in a shallow puddle against the wall. The nametag on the torn fragment of uniform next to it read “Nguyen.” Mark closed his eyes, fighting a wave of nausea and grief. He forced himself to move on. He couldn’t help anyone back there anymore. All he could do was survive and pray some of his crew had made it to the forward compartments alive.

Gun in hand, he edged along, senses straining for any sign of the intruder. The corridors were cramped to begin with, but now with debris and partially closed hatches cluttering the way, Mark felt as though the walls were closing in on him. Every few feet he had to sidestep jagged chunks of metal or collapsed pipes. Once, he had to climb over the fallen body of an officer – the man’s face mercifully unrecognizable beneath a coating of corrosive blue. Mark didn’t stop to check for a pulse; the way the body’s flesh had dissolved told him enough.

As he neared an intersection, a faint light flickered at his feet. Looking down, he saw a small penlight lying in the gore, amazingly still functioning. He picked it up and clicked it off – its steady beam was a liability, announcing his presence. Better to rely on the intermittent emergency lights, as unnerving as their on-and-off rhythm was.

Mark’s ears caught a subtle sound and he froze. It was a wet scraping noise, coming from somewhere ahead – maybe around the next bend. He held his breath, finger tight on the pistol’s trigger. The sound stopped. In the silence, Mark’s own heartbeat thundered in his ears. It could be anywhere… he thought, skin crawling at the memory of how easily the creature had slipped away earlier.

The corridor ahead remained still, bathed in half-darkness. Mark carefully inched forward and peered around the corner. His breath caught. There, about ten yards down the passage, the heavy pressure door leading to the torpedo room was sealed shut – and smeared across its small circular window was a handprint in blood. On the floor below the window, a crimson puddle had collected, as if someone had bled out right against the door. The sight was gut-wrenching, but also potentially hopeful: if the door was sealed, perhaps someone was alive inside, having locked it. Maybe they had wounded, explaining the blood. Mark had to know.

He crept toward the torpedo room door, each step deliberate and soft. Every nerve in his body screamed caution; this area was drenched in blood, meaning the creature had certainly been here. But now it seemed absent – no sign of slithering limbs or movement in the gloom. Perhaps it had retreated after making its carnage, or gone back down to the flooded sections below.

When Mark reached the door, he pressed his cheek against the cool metal and tried to peer through the glass. The other side was dark. He tapped the window lightly with the barrel of his gun. “Hello?” he whispered, voice barely audible. “Anyone in there?”

For a moment, nothing. Then – movement. A shifting shadow and a weak beam of a flashlight from within. Mark felt a surge of relief as a face appeared on the other side of the blood-smeared glass. It was Sub-Lieutenant Harris, one of the weapons officers. His eyes went wide at seeing Mark, and he immediately spun the wheel to unseal the door. With a creak, it opened a crack, and Harris’s trembling hand beckoned Mark in.

Mark slipped through, quickly spinning the wheel to dog the hatch tight again. Inside the torpedo compartment, it was hot and stank of copper and sweat. The red emergency lighting was barely functioning here, too. Huddled behind an overturned torpedo loading trolley were three other survivors – two sailors from navigation and, to Mark’s surprise, Captain Reinhardt himself. The captain sat propped against the bulkhead, one hand pressed to a blood-soaked bandage on his thigh. He looked pale but alive.

“Mark,” Captain Reinhardt breathed in visible relief. “Thank God. I thought…” He trailed off, taking in the XO’s disheveled and blood-spattered state.

Mark knelt beside him, hardly believing he was seeing his CO alive. “Captain, are you injured badly?”

“Took a piece of shrapnel or something when… when that attacked,” the captain replied through grit teeth. “I managed to limp here. Harris got this door sealed just in time.” He nodded to the young lieutenant who stood guard nervously with a wrench in hand.

The two sailors, Parker and Singh, gave Mark wan smiles. They were both bruised and shell-shocked, but seemed stable. Mark quickly recounted what had happened in engineering and how he’d contained the creature temporarily, and the horror with Yates. He tried to keep his voice clinical, but it shook when he mentioned the infections. Parker visibly blanched.

“It dragged some of the crew out,” Harris added quietly, gesturing to the bloody handprint on the door. “Chief Franklin was closing the door from the outside, buying us time… it… it grabbed him at the last second.” Harris’s voice hitched. “Pulled him away. We heard his scream cut off and…” He pointed to the gore on the threshold with a helpless look. Mark squeezed the young man’s shoulder, jaw clenched. Franklin had been a good man. There was no time to mourn now, but later, Mark promised himself, he would remember every fallen comrade.

Captain Reinhardt inhaled sharply, regaining command of himself. “Davis, status of the sub?”

Mark shook his head grimly. “Engines down. We have flooding in at least two compartments. Comms are out – I tried to radio a mayday but I don’t think it broadcasted. We might be dead in the water.”

The captain nodded, eyes heavy with the weight of their dire situation. “Reactor scrammed automatically. We’re running on batteries, but not for long.” He winced, shifting his leg. “Do we know what that thing is?”

“A nightmare,” one of the sailors mumbled, wiping sweat off his face.

Mark hesitated. In the back of his mind, a realization had been creeping in, connecting what they’d encountered with rumors and briefings of unexplained events – the dead fish in the Atlantic, bizarre sonar contacts. He thought of Priya Das at Fort Armitage, always going on about unusual deep-sea finds… Mark had dismissed most of it as above his pay grade. But now— “I think… it’s some kind of cephalopod, sir,” he finally said softly. “An octopus or squid, but far beyond normal size or intelligence. Maybe the kind of thing those eggheads at the lab were talking about.”

Reinhardt’s expression darkened, as if he too recalled warnings unheeded. But there was no time to dwell. The hull groaned loudly, and all of them looked up instinctively. The sub was settled at an angle; Mark only now noticed that the floor here had a slight tilt, indicating they’d likely come to rest on the seabed or a shelf. If that was the case, rescue would have to come from above. If it came at all.

Before anyone could speak again, a muffled clang echoed from down the corridor outside the torpedo room. Everyone tensed. Harris raised his wrench, and Mark re-gripped his pistol, checking the chamber: three bullets remained, which he’d intended for himself if it came to it. Now they might serve a different purpose.

Another clang, closer. A scraping. Mark motioned them all to kill their flashlights. Darkness cloaked the compartment. In the silence, they could hear water dripping… and something else. A skittering sound, like nails dragging lightly on a chalkboard, traveled along the outer hull. It passed by the torpedo room, then halted. Mark’s heart thudded in his chest. The others were rigid, barely daring to breathe.

In the faint emergency glow, Mark saw Captain Reinhardt quietly reach for the emergency torpedo launch lever. For a wild moment, Mark thought the captain meant to fire one of the warheads at the creature point blank, but no – Reinhardt instead flipped open a cover next to the lever, revealing the self-destruct priming switch. Mark realized with a mix of admiration and horror that the captain was prepared to scuttle the sub and everything in it to prevent this creature from reaching civilization – and perhaps to grant them all a mercifully quick end.

Mark shook his head slowly, putting a hand on Reinhardt’s arm. Not yet. They still had a chance, slim as it was, to escape and report this attack topside. The captain met his eyes, then reluctantly closed the cover, leaving the scuttle unprimed.

A sudden thud against the torpedo room door made Parker stifle a scream. The metal rang from the impact, but held. Mark aimed his pistol at the door, finger on trigger, though he knew if the creature breached it would take more than bullets to stop it. Everyone waited, tense seconds stretching like hours. The thumping did not repeat.

Instead, a new sound sent ice through Mark’s veins: a slow, heavy slithering just outside, accompanied by the subtle suck and release of suction cups on steel. The creature was here, just beyond the door, moving leisurely. Mark realized with dawning dread that it knew exactly where they were. It was toying with them, perhaps savoring their terror. Through the door’s small window, now mostly smeared with dried blood, a moving shadow passed, blocking the faint light from the corridor.

Harris made a soft whimpering sound. The captain closed his eyes as if in prayer. Mark braced himself. In the chaos earlier, they’d been reacting on instinct. But now, sealed in this compartment, they were like foxes cornered in a cave by a serpent. Mark felt a surge of anger through the fear. If he was going to die here, he’d at least look that monster in the eye and fight to his last breath.

On cue, as if sensing his resolve, the c’thalhai struck. The thick steel door dented inward with a single tremendous blow. Bolts popped, clattering to the floor. Parker yelped and scrambled back. Another impact – the dent deepened, a shriek of metal sounding as the hatch hinges tore.

“Move, move!” Mark yelled, shoving the others toward the back of the compartment behind stacks of munitions crates. The door wouldn’t hold; he needed a backup plan. His eyes darted around frantically and fell on the torpedo tubes. The inner tube doors were dogged shut, but those led directly out of the sub… if someone could crawl in and eject manually, they might escape to the surface. It was a desperate thought – who knew if anyone could survive the ascent or the ocean pressure. But it was a chance.

“Captain,” Mark hissed, “we can flood the torpedo tubes and ride them out to the surface with emergency vests.”

Reinhardt grimaced in pain, but nodded. “Do it. Get them out.” He clearly didn’t count himself among those escaping.

Mark beckoned Harris and Parker. “Help me prep tube one!” Singh, the other sailor, fearfully kept his eyes on the door, pistol in a shaking hand pointed at the bulge forming there.

They spun the manual wheels to open the inner torpedo loading hatch. Cold seawater trickled out – the outer doors were still closed, but the tube had slight leakage. There was enough space for maybe two people to squeeze in at a time if they were nearly on top of each other.

CRASH! The torpedo room door flew off its hinges with an ear-splitting screech, crashing to the deck. In the doorway writhed a mass of pale tentacles, illuminated by the emergency light reflecting off the puddles of water. The c’thalhai’s bulk blocked the exit entirely. It paused there, a hulking silhouette, as if relishing the tableau of panicked humans before it. Mark caught a glimpse of its hellish form once more – the conical head brushing the top of the doorway, its many limbs coiling with lethal grace. Two eyes now stared in at them, one fixed on Mark and the others, the second roving around independently. In the dim light, those eyes gleamed with what could only be described as malicious delight.

“Fire!!” Captain Reinhardt roared, raising a flare gun he’d pulled from an emergency kit. He squeezed the trigger. With a whoosh, the flare shot out, a comet of white-hot magnesium, and struck the creature’s upper body. Fwoosh! The compartment lit up like daylight as the flare stuck and sputtered against the c’thalhai’s slimy hide. The creature shrieked – a warbling, piercing scream – as smoke curled from the point of impact. The intense heat seared its flesh; chunks of charred, blackened skin sizzled, giving off a nauseating burnt-octopus stench.

At the same time, Singh opened fire with his pistol, emptying the entire magazine wildly into the mass of tentacles. Mark added his own remaining shots, aiming for one of the creature’s huge eyes in the glare of the flare’s light. One bullet hit the mark – the eye burst in a spray of viscous dark fluid. The c’thalhai’s scream escalated into a frenzied, mind-shattering keen that made everyone clamp hands over their ears.

The monster convulsed, slamming its injured body against the door frame in agony or rage. The entire sub shook with the impact. Parker was thrown off his feet; Mark clung to a railing to stay upright. The creature thrashed, tentacles flailing into the room now without coordination. One crashed into Singh, sending him sprawling lifelessly against the bulkhead with a snapped neck. Another coiled around Captain Reinhardt’s legs and yanked – the captain was dragged towards the door before anyone could grab him. “Captain!” Harris shouted, reaching out, but too late. Reinhardt gave Mark one final look, a strangely calm expression of acceptance, before he was pulled into the writhing mass. His scream was cut off as a serrated arm wrapped around his throat and squeezed.

Mark felt something break inside him at the sight of his captain’s body being whipped about like a ragdoll amidst the tentacles. But the flare was still burning, lodged near what might be the creature’s maw, spewing molten sparks. The c’thalhai was partially in retreat, rearing back slightly from the painful heat. Now or never.

“Get in the tube!” Mark bellowed to Harris, who stood frozen between fight and flight. Mark practically hurled the young officer toward the open torpedo tube. Harris snapped out of it and scrambled into the narrow cylinder feet-first, making room. Parker was already at the tube’s mouth, hyperventilating in panic. Mark shoved him in after Harris. It’d be a tight fit but he had no choice. “Go! Hold on to each other and hit the buoyancy vest once you’re out!” Mark slammed the inner hatch closed on them, giving Parker a last encouraging nod through the small glass – the sailor’s face was white with terror but he nodded back.

Another slimy tendril lashed toward Mark, nearly catching his arm. He spun the torpedo tube lock wheel. The mechanism groaned; for a heart-stopping second it jammed, but then clicked – sealed. He slapped the manual launch lever. There was a heavy thunk from within as the outer torpedo doors blew open and seawater flooded the tube, ejecting its living cargo out into the ocean. Godspeed, Mark thought, praying they’d make it to the surface alive.

A piercing, keening wail snapped Mark back to present danger. The c’thalhai, engulfed in smoke from its own smoldering flesh, lunged fully into the compartment now, incandescent fury in its remaining eye. Mark dove behind the torpedo loading console as a barbed arm spearheaded through the air where he’d stood. It slammed into the bulkhead, punching clean through several inches of steel with horrifying ease. Sparks showered as it withdrew, leaving a gaping hole.

Mark crawled, adrenaline on override, trying to put anything between him and the creature. His hand brushed something solid and he realized with a mix of despair and grim resolve that it was the captain’s scuttling device – a detonator for the sub’s self-destruct charges, torn from Reinhardt’s belt when he was taken. In that moment Mark knew: the Reliant was lost, and so was any hope of completely escaping this monster. But maybe he could ensure it died with the ship. Perhaps that would give the men he’d launched a chance if they were picked up. And maybe it would serve as a warning to whatever rescue or search teams eventually came – a beacon of destruction to announce what lurked below.

He snatched the detonator and backed against the far wall. The c’thalhai was advancing, half its bulk now in the room, crawling over crates and machinery, its arms coiling along walls and ceiling. The flare had gone out, leaving charred, smoking wounds, but it only seemed to have enraged the thing further. It moved with a predatory slowness, knowing Mark had nowhere to run.

A slim tentacle whipped out and seized Mark by the ankle. He gasped as it yanked him off his feet, dangling him upside down. The pistol fell from his grasp, clattering to the floor. In seconds, another thicker appendage snaked around his torso, pinning his arms to his sides. The creature hauled him up like a prize catch until Mark was dangling face-to-face with its grotesque visage.

He found himself staring into a ring of razor-sharp teeth mere inches away – the beak-like maw opened and a gurgling hiss poured forth, splattering Mark with foul drool. Behind that, the great unblinking eye bore into him, reflecting his own terrified expression. The scent of decay and acid was overpowering.

Mark clenched the detonator tight. The c’thalhai seemed almost to notice the small device. A tendril with curious, delicate feelers crept toward Mark’s hand, as if to inspect or pluck the object away. Summoning every remaining ounce of strength and resolve, Mark gripped the trigger.

He mustered a ferocious glare at the abomination that had doomed his ship and slaughtered his crew. In that instant, suspended between life and death, Mark Davis felt oddly calm. If you’re taking me, I’m taking you with me.

He pressed the detonator. BOOM—

An ear-splitting explosion ripped through the Reliant. In a microsecond, the torpedo warheads and scuttling charges detonated in a chain reaction. The torpedo room was obliterated in a blinding fireball. Metal bulkheads peeled apart like paper. The last image Mark saw as the flames engulfed everything was the c’thalhai’s eye widening in what looked unmistakably like shock. Then came a searing flash and merciful oblivion.

Far above, on the moonlit surface of the Atlantic, the calm was shattered as the ocean bulged and foamed. With a thunderous roar, a column of water erupted upward, lit from beneath by a brief orange glow. Debris – twisted shards of steel hull, shards of metal, and unidentifiable chunks – burst forth amid the spray. For a moment, the silhouette of a submarine’s aft section breached, only to sink back under, disappearing into the dark depths from which it came.

Moments later, two figures in inflatable life vests bobbed up amidst the churning waves, coughing and gasping: Harris and Parker, flung free from the shockwave, but miraculously alive. They clung to one another, eyes wide at the carnage. Flaming oil slicks dotted the surface as fragments of the Reliant’s death rose to meet the night air.

As the sea settled and dawn’s first light stretched tendrils of gray across the horizon, the two survivors stared in stunned silence. The waters around them were turning a sickly shade of blue, and in that cool morning light they watched as something inhuman slithered just below the surface nearby – a massive, charred tentacle, twitching weakly as it floated past. Its once-glowing patterns were dark. With a final shudder, the appendage sank beneath the waves, leaving only oily ripples.

In the distance, faint but growing louder, the thump of helicopter blades could be heard, and the wail of sirens from a responding ship. Help was coming. But for Lt. Cmdr. Mark Davis and the brave crew of the USS Reliant, the fight was over.

On the rescue helicopter’s approach, a medic with binoculars surveyed the scene and felt his blood run cold. Amidst the wreckage and foam, the flicker of emergency flares cast eerie shadows, and for one surreal moment he thought he saw a colossal shape moving under the water, illuminated by the rising sun – as if some dark leviathan were sinking back into the abyss. He blinked and it was gone, leaving only an ominous calm and a slick of blood on the surface.

Whatever had happened here was only the beginning, he suspected. The ocean had given up a terrifying secret this dawn – one written in blood and fire on the waves – and the world above would never be the same.
