Chapter 2: Blood Warning
The hiss of the automatic doors sliding open was obscenely loud in the suffocating silence. It sounded like the building taking a breath. Stale, chilled air, thick with the clinging antiseptic reek of a long-dead laboratory and the coppery undercurrent of old blood, washed over McCall and Reyes. The lobby stretched before them, cavernous and sterile under the flickering, faltering glow of emergency lighting strips running along the high ceiling. Polished white tile floors reflected the sickly light, disappearing into shadowed corridors. Empty security stations. Abandoned chairs. Dust motes danced in the failing beams like agitated insects.
McCall entered low and fast, rifle sweeping left to right, finger resting alongside the trigger guard. His boots made sticky, tacky sounds on the tiles. Reyes mirrored him, backing in, their sniper rifle covering their six, scanning the still-open entrance and the desolate landscape beyond. The storm clouds outside bruised the sky, deepening the gloom within.
“Clear left,” McCall murmured, his voice swallowed by the echoing space.
“Rear clear,” Reyes responded, their voice tight. The tremor was back, vibrating the barrel of their rifle minutely. “For now.”
McCall advanced deeper, the unnatural silence pressing in. No generator hum. No distant chatter. Just the oppressive weight of abandonment and the frantic thud of his own pulse in his ears. His eyes scanned the walls, the corners, the doorways leading off the lobby. Standard corporate research aesthetic – cold, functional, soulless. Or it had been.
“Look,” Reyes breathed, the word barely audible.
McCall followed their gaze. Against the far wall of the lobby, near a sealed doorway marked ‘SECURITY ACCESS - LEVEL 1 CLEARANCE REQUIRED’, something was deeply wrong. The smooth white wall surface buckled and warped, as if the interior structure had melted and flowed before solidifying into a grotesque sculpture. Embedded within that warped, tumor-like protrusion was a figure.
Dr. Aris Thorne.
Or what remained of him.
The tall, lanky frame was fused seamlessly into the wall material from the waist down. His torso leaned forward at an impossible angle, arms outstretched and rigid, fingers splayed against the wall above his head like he’d been frozen mid-fall. His bald head was tilted back, thick-rimmed glasses askew on his nose, revealing eyes wide open, clouded with a horror that transcended death. His mouth was stretched wide in a silent, eternal scream, lips pulled back taut over his teeth. Environment suit? Gone. He wore only shredded remnants of a lab coat fused into the mottled grey substance that had consumed the lower half of his body. The substance wasn't concrete or plaster; it looked organic, fibrous, glistening faintly in the dim light like wet muscle tissue.
Beneath Thorne’s outstretched, claw-like hand, scrawled in dried, flaking brown blood directly onto the wall surface, were three words:
IT WATCHES THROUGH US
McCall felt the blood drain from his face. His gut clenched, a fist of ice tightening in his stomach. The coppery smell intensified, mixed with a new, nauseating sweetness – decay mingled with ozone and something sharp, chemical. Reyes made a choked sound beside him, a mix of horror and visceral recognition.
“Phase Three…” Reyes whispered, the words catching in their throat. Their rifle wavered. “It… it used him. Like the transmission said. Absorbed.”
McCall forced himself forward, rifle trained not on Thorne, but on the darkened corridors radiating out from the lobby. His boots stuck to a tacky patch on the floor near the gruesome tableau. Blood. Old, congealed. Lots of it. Spray patterns marred the pristine white tiles.
“Thorne,” McCall stated, his voice rough but steady. He scanned the scientist’s fixed, terrified eyes, the twisted posture. “Where’s the main lab? Where’s the data core? Where are the others?”
It was a futile question to a corpse, but the act of asking grounded him. Procedure. Mission. Get the data. Survive. He tore his gaze from Thorne’s face to the blood message. IT WATCHES THROUGH US. A chill that had nothing to do with the air conditioning crawled up his spine.
“Main lab should be sub-level two,” Reyes said, their voice regaining a shred of control, though their eyes remained locked on Thorne. “Access elevator… probably back that way.” They gestured vaguely towards a corridor marked with faded directional signs: 'LABORATORIES', 'ADMIN', 'SUB-LEVEL ACCESS'.
As McCall turned to scan the indicated corridor, the emergency lights flickered violently. Not just a power surge. They pulsed. Once. Twice. A stuttering rhythm.
Thud-thud… Thud-thud…
It matched the frantic pounding in McCall’s own chest.
He froze. Reyes sucked in a sharp breath.
The flickering slowed, steadied into a deep, rhythmic pulse. Thud-thud… Thud-thud… Synchronized perfectly now.
With their heartbeats.
McCall looked down. The shadows pooling at the base of the walls, lurking in doorways, stretching long and thin from overturned furniture… they weren't still. They pulsed. Subtly, almost imperceptibly, swelling and receding in time with the lights, in time with the hammering of blood in their ears. The lobby itself seemed to breathe.
Thud-thud…
The warped material around Thorne’s fused legs seemed to glisten wetly for a second. The clouded eyes in the scientist’s frozen face… did they just twitch? Focus?
McCall’s finger slid onto the trigger. “Reyes! Eyes front!”
Reyes snapped their rifle back towards the corridors, breathing ragged. “What… what is it doing?”
“Learning,” McCall grated out, the word tasting like ash. “Learning us. Our fear. Our rhythms.” He kept his rifle scanning the pulsing shadows. “We don’t split up. We don’t stop. Main lab. Now. Cover that corridor.” He started moving sideways towards the 'SUB-LEVEL ACCESS' passage, keeping Thorne's wall in his peripheral vision, the pulsing shadows, the blood message.
Thud-thud… Thud-thud…
The lights pulsed. The shadows breathed.
As McCall passed directly in front of Thorne’s grotesque monument, the clouded eyes snapped open wider. Not a trick of the light. The head tilted forward with a faint, wet crack. The silently screaming mouth seemed to gape impossibly wider. And from the wall beneath the blood-scrawled warning, fresh, dark liquid welled up, impossibly black, oozing over the letters 'US'.
It began to flow downwards, tracing new lines. Not random. Forming letters.
Thud-thud… Thud-thud…
The pulsing intensified. The shadows deepened, stretching tendrils of darkness across the floor towards their boots. The fresh, black fluid on the wall finished its gruesome inscription, dripping thickly beneath the original words:
IT WATCHES THROUGH US
AND IT HUNGERS
The emergency lights died. The lobby plunged into absolute, suffocating darkness. The only sound was their own ragged breathing, synchronized with the pulsing void.
Total blackness clamped down, thicker than any night McCall had known. His own breath rasped in his ears, loud as a scream, perfectly timed with the slow, heavy thud-thud vibrating up through the soles of his boots. Reyes’ choked gasp beside him synced perfectly. The air tasted metallic, charged, pressing in like wet clay. It stank of decay, ozone, and something unsettlingly sweet.
"Light!" McCall barked, the word sharp, slicing the suffocating quiet. "Now!"
Reyes fumbled, equipment rustling harshly against their tactical vest. A click. The beam of Reyes’ rifle-mounted light speared the darkness, cutting a stark, trembling cone through the void. It landed first on the wall where Thorne was entombed.
The fresh, black fluid still oozed sluggishly beneath the words 'AND IT HUNGERS'. The fibrous, glistening material encasing Thorne’s lower half seemed to undulate gently, almost breathing. Thorne’s twisted head hadn’t moved again, but the light caught the unnatural sheen on his wide, clouded eyes. McCall swept his own light on, the twin beams converging, then separating.
"Jesus," Reyes whispered, the light trembling over the blood-sprayed tiles leading towards the 'SUB-LEVEL ACCESS' corridor McCall had indicated. The path wasn't clear. Where pristine white tile should be, thick, dark tendrils of what looked like congealed chaos pulsed rhythmically, spreading like spilled ink from under closed doors and along the baseboards. They seemed to throb in time with the pervasive thud-thud.
"Move!" McCall ordered, his voice low and hard, stepping forward onto the corrupted tile. His boot sank slightly into the fibrous muck with a sickening squelch. "Keep those lights moving. Cover angles." He advanced, rifle stock tight against his shoulder, forcing his breathing to slow, fighting the instinct to bolt. The pulsing in the floor vibrated through his legs, syncing with the frantic hammering in his temple.
Reyes followed half a step behind and to the right, their light darting nervously down intersecting hallways. "Clear... clear... God, this stuff is everywhere." They kicked a discarded chair aside; it scraped across the pulsating muck, leaving a temporary trail before the darkness flowed back. "Sub-level access should be... left here."
They rounded a corner. McCall’s light illuminated a heavy, reinforced door, its electronic access panel dark and dead. More of the fibrous corruption crawled over its surface and pooled thickly at its base. A faded sign read 'ELEVATOR TO SUB-LEVELS 1-3'. This was the choke point. McCall scanned the ceiling, the walls flanking the door – nothing visibly moved except the slow, rhythmic pulse within the glistening slime. The thud-thud felt faster now, tighter, matching his own escalating pulse.
"Cover me," McCall said, slinging his rifle and pulling a compact pry bar from his pack. He jammed the flat end into the narrow gap between the heavy door and its frame, near the manual release. "Getting this open’s gonna be loud. Be ready."
"Heard," Reyes confirmed, their voice tight but steady now, adopting a wider stance, rifle light sweeping the corridor behind them. Their beam caught the glint of movement in the distant lobby shadows – just a flicker, like something large shifting position. "Movement back there, Skipper. Distant."
"Noted." McCall braced himself, took a breath, and heaved. Metal shrieked in protest. The corruption coating the door bulged and stretched. He strained, tendons standing out on his neck. Another heave. A loud crack echoed as the locking mechanism sheared. The door groaned open about six inches, revealing only darkness beyond. Cold air, smelling of damp concrete and stagnant chemicals, sighed out. The thud-thud pulsed harder against his boots.
"Shove!" Reyes urged, glancing back towards the lobby. Their light beam jerked erratically. "Faster, Derek!"
McCall dropped the pry bar, grabbed the door edge with both gloved hands, and threw his weight against it. It scraped open another foot. He squeezed through the gap sideways, rifle first, light probing. Reyes followed instantly, turning to cover the corridor they’d just left as McCall pulled the heavy door mostly shut behind them. It wouldn't latch.
They stood in a small, square elevator lobby. No elevator. Just an open shaft yawning before them, cables hanging like dead vines in the gloom. A skeletal metal maintenance ladder ran down one side. McCall’s light swept down; the shaft plunged into utter blackness. His beam caught the top of the elevator car itself, maybe fifteen feet below, its roof hatch slightly ajar. The thud-thud vibration was muted here, dampened by the concrete shaft, but still present. A deeper, slower echo seemed to resonate from the depths.
"Ladder," McCall stated, already swinging a leg over the shaft’s edge, boot finding the first rung. "Fast and quiet. Reyes, down. I'll cover top." He braced, rifle pointed back towards the gap in the heavy door they’d just forced. The darkness beyond that gap felt intensely watchful.
Reyes didn't hesitate, slinging their rifle and clambering onto the ladder, descending quickly. Their light beam danced erratically below. "Ladder's wet. Slimy. Careful." Their voice echoed slightly in the confined space.
McCall kept his light fixed on the door gap. Nothing moved through it. Yet. The rhythmic pulse throbbed in his jaw. He heard Reyes land with a soft thud on the elevator roof below. "Clear down here. Hatch is open."
McCall took one last look at the dark rectangle of the doorway above. Stillness. An unnerving, waiting stillness. He turned and started down the ladder. The rungs were indeed slick with the same glistening residue. Halfway down, a sound froze him. Not a pulse. A wet, sliding scrape. From inside the elevator shaft, below him, near Reyes.
Reyes’ light snapped upwards, wide-eyed terror visible even in the harsh beam. "Something's moving!" they hissed. "Inside the shaft! Below the car!"
McCall dropped the last few feet, landing beside Reyes on the roof. He shone his light down into the narrow gap between the elevator car and the shaft wall. Darkness. Then, a thick, segmented shape, glistening black like oil-slicked obsidian, slid sinuously past the beam. It vanished into the depths. The rhythmic thud-thud surged, vibrating the ladder, the cables, the metal roof beneath their boots. Synchronized. Hungry.
"Go! Now!" McCall rasped, shoving Reyes towards the open hatch. Reyes dropped through instantly. McCall followed, landing hard inside the elevator car just as a heavy, wet impact slammed against the roof above them. Dust shook loose. A deep, resonant scraping sound, like stone on stone, echoed down the shaft. The pulsing intensified, shaking the car, a frantic drumbeat syncing perfectly with McCall’s own racing heart as he slammed the roof hatch shut. The scraping immediately intensified into frenzied pounding.
"Main lab level! Now!" McCall yelled, scanning the elevator's control panel. Reyes stabbed the button for Sub-Level 2. Nothing. Dead. Reyes cursed, ripping off a panel below the buttons, fingers flying across wires. Sparks spat. The elevator lights flickered, then glowed a sickly yellow. The car shuddered violently as another heavy impact dented the roof. Reyes jammed wires together. The doors began to slide shut with agonizing slowness. Through the narrowing gap, McCall saw thick, black pseudopods, dripping with the same fibrous slime, slithering down the ladder towards them from above. Synchronized with the pulsing. With the pounding on the roof. With his own terror. The doors closed with a final, echoing clunk. The car lurched downwards.
The elevator groaned as it descended, cables shrieking in protest overhead. Each jolt vibrated through McCall’s bones, echoing the frantic pounding still denting the roof. Reyes braced against the wall, breathing hard, their light jerking between the shuddering ceiling hatch and the control panel. "Wiring’s fried deeper," they panted. "This is as smooth as it gets."
Darkness swallowed them whole between the sporadic flickers of the emergency light. The metallic taste of blood filled McCall’s mouth – he’d bitten his tongue. The air reeked of burnt insulation, ozone, and that underlying, nauseating sweetness mixed with damp concrete. The heavy scraping sounds from above lessened, but didn’t stop. Something large shifted, settling its weight. Waiting.
"Sub-Level Two," Reyes announced, their voice strained as the car ground to a halt. The doors hissed, then jerked open about a foot with a sound like tearing metal. Stale, frigid air, thick with decay and that sharp chemical stench, washed in. Beyond the gap, utter blackness pulsed.
McCall slammed his shoulder into the reluctant door, forcing it wider. His rifle light cut a path into the corridor. Reyes’s beam joined it, revealing a scene ripped from a fever dream. The sterile research facility was gone. The walls, floor, and ceiling were encased in thick, undulating layers of the same glistening black material they’d seen upstairs. It pulsed rhythmically, a slow, deep thud-thud that resonated in their chests. Veins of sickly greenish light pulsed beneath its surface like corrupted blood through arteries. Emergency lights flickered weakly, their light seemingly absorbed by the living darkness coating everything.
"Like… like walking inside something," Reyes breathed, revulsion twisting their features. They stepped out cautiously. Their boot sank into the fibrous muck with a wet squelch. The stuff yielded like rotten meat, then closed hungrily around their ankle for a second before they pulled free. McCall scanned the corridor. Doors were warped shut, fused by the growth. Debris – overturned gurneys, shattered monitors – lay half-submerged. Silence pressed in, broken only by the wet pulse of the walls and their own ragged breathing.
"Lab’s gotta be this way," McCall said, his voice low and tight. He pointed the rifle light down the left branch of the T-junction ahead. The beam barely penetrated the oppressive gloom, swallowed by the light-absorbing growth. "Stay sharp. That shit upstairs could be anywhere."
Reyes nodded, falling in step slightly behind McCall, covering their six. Their light swept the pulsating ceiling, the fused doorways. Each step was an effort, pulling free from the sucking muck. The thud-thud vibration traveled up their legs. McCall focused on the mission: Find the main lab. Secure the data core. Get out. The words felt flimsy against the visceral wrongness pressing in. Thorne’s silent scream flashed in his mind. IT WATCHES THROUGH US.
They reached the T-junction. McCall paused, listening. Only the pulse. The breathing walls. He gestured left again. Reyes took point for the brief crossing, their light scanning the right-hand corridor. Nothing moved in the thick shadows. McCall moved left.
Thump.
McCall froze mid-step. Reyes stopped instantly behind him.
Silence. Just the liquid pulse of the walls.
McCall strained his ears. Had it been a settling noise? A piece of debris finally succumbing? He took another cautious step forward, his boot pulling free with a soft, sucking schlup.
Thump.
It came from directly behind him. Clear. Distinct. A footstep. Landing perfectly in the split-second pause after his own.
Reyes whirled, rifle snapping up, light blindingly bright in the confined space. The corridor behind them was empty. Just the pulsating black walls, the submerged debris, stretching back into darkness. Their beam shook violently. "Derek..." they whispered, pure terror stripping their voice bare.
"Hold position," McCall ordered, his own voice a gravelly rasp. He didn’t turn. Turning felt like an invitation. His finger was welded to the trigger. Sweat stung his eyes. The corridor ahead was just as dark, just as empty. The pulsing thud-thud hammered against his skull. He forced himself to take another deliberate step.
Thump.
The sound echoed his movement perfectly. A fraction of a second after his boot landed. It came from behind again, but closer now. Right where Reyes was covering. McCall saw Reyes flinch as if struck. Their rifle barrel dipped for a split second before snapping back.
"Nothing!" Reyes choked out, panic rising. "There's nothing fucking there!"
McCall knew. He understood the sheer, sanity-bending terror coiling in Reyes’s gut because it was twisting his own. This wasn't an enemy you could shoot. It wasn't hiding. It was mimicking. Learning their rhythm. Using the very air, the structure, against them. IT WATCHES THROUGH US. The thought wasn't his own. It felt inserted. Cold. He took a slow, deliberate breath, trying to break the rhythm. To be unpredictable.
Thump.
It wasn't behind him this time.
The sound came from ahead. Down the corridor he was facing. A single, heavy footstep landing in the thick muck. Exactly where his next step would have fallen if he hadn’t paused. McCall’s blood turned to ice. Reyes gasped.
Before McCall could react, a new sound cut through the oppressive pulse.
Thump-thump-thump.
Rapid. Purposeful. Coming down the corridor towards them.
