Chapter 1: The Blade's First Cut
The hallway stretched in either direction, a prison of sterile white. The floors were seamless, polished to a high gloss that reflected the cold, recessed lights in the ceiling like stars trapped in ice. Smith stood perfectly still, a rigid statue in a cheap navy blazer and skirt. Her clipboard was a shield pressed against her chest.
The smell was wrong today. Beneath the usual bleach and disinfectant hung a coppery tang, like old blood left in a petri dish. It made her want to scrub her sinuses.
“This is unacceptable,” she said, her voice cutting the silence. It wasn’t raised. It didn’t need to be. “Running in the halls is expressly prohibited. The signed agreement is very clear.”
The two liminal girls shifted, their forms flickering at the edges in the mirrored walls. One had the faint, translucent outline of moth wings. “We weren’t running,” Moth-Girl muttered. “We were… flowing with heightened momentum.”
“Semantics.” Ms. Smith’s pen tapped the violation log. “It’s a safety issue. You will report to the reflection chamber for a calibrating hour. Both of you.”
A skittering sound echoed from the far end of the corridor. Tiny, like insect legs on glass.
All three of them turned. Smith’s knuckles went white around the clipboard. “What was that? Is one of your… familiars loose again?”
The girls shook their heads, their wide eyes genuine. The skittering came closer, a rapid tik-tik-tik-tik that seemed to come from everywhere and nowhere, reflected and multiplied by the mirrors.
“Return to your quarters. Now,” Ms. Smith commanded, her tone leaving no room for debate. The girls didn’t need telling twice. They melted away down a side passage, their forms blurring.
She was alone. The tik-tik-tik stopped.
The silence was worse. It was a thick, listening silence. Smith straightened her blazer, took a steadying breath. She was being ridiculous. It was a vent, or a faulty light ballast. This place was always making noises. She took a step forward, her sensible heels clicking sharply.
A shadow detached itself from a seam in the wall where no seam should be.
It was small, the size of a cat, but built of angles and hard, chitinous plates. It had too many legs, moving in a frantic, scissoring gait. In front of it, held in a barbed appendage, was a sliver of light so thin it was almost invisible. A blade. It hummed with a faint, painful frequency.
Her brain refused it. This was not in the handbook. This was not part of the exchange program guidelines.
She froze.
It moved faster than anything that small should. It was a dart of polished darkness under the lights. It didn’t run at her; it simply appeared at her feet, and then it was ascending, a nightmare spider up the ladder of her body. She felt the prick of its legs through her stockings, a cold touch on her thigh, her hip.
She gasped, tried to bat it away.
It reached her waist. The blade, that humming sliver, touched the fabric of her skirt just above her hip. There was no pressure. No resistance.
A line of perfect cold drew itself across her abdomen.
She looked down. A faint white line appeared on her blazer, her shirt, her skirt. It didn’t look like much. A thread of frost. Then the cold turned to fire.
She screamed. A short, sharp sound of utter shock.
The world did not go dark. It split.
There was a sound like tearing silk, but it came from inside her. A visceral, wet parting. Her vision doubled. She saw the hallway, the mirrors, but she saw it from two sets of eyes, side-by-side, the perspectives overlapping and swimming.
Her clipboard clattered to the floor.
She fell. But she was two.
Two torsos, two heads, four arms—all connected, horribly, seamlessly, to a single pair of legs that were now buckling. They toppled sideways, a tangled, naked heap of pale limbs on the cold, reflective floor.
The creature dropped, its task complete, and skittered back into the wall seam, gone. Smith panted. They panted. The air was freezing on skin that had not felt open air in twenty years. She felt her own bare shoulder against the floor. She felt another shoulder, identical in every slope and mole, pressed against her back. The intimacy was violent, suffocating.
She tried to push up. They tried to push up. Four arms flailed, working at cross-purposes. One hand slapped her own face. Another clutched at the arm attached to the torso behind her.
“Stop,” a voice said. It was her voice. But it came from behind her left ear.
“You stop,” her own mouth said back, the words a ragged breath.
They managed to get onto their shared knees, one pair of legs wobbling beneath the unnatural balance of two upper bodies. In the mirrored wall, the reflection stared back.
Two women. Identical. Sharp, hawkish faces pale with shock, graying hair fraying from identical tight buns. Naked from the waist up, their torsos joined at the flank in a smooth, impossible curve of flesh and spine that descended into one shared waist, one pair of hips, one set of legs. They were conjoined. A perfect, terrible symmetry.
The Ms. Smith on the left looked at the Ms. Smith on the right. They did it at the same time. Same wide, horrified eyes. Same parted lips.
“What,” they said in unison. The synchronicity was worse than the silence.
The right one—she was the right one now, she had to be something—clutched her own arms over her chest. She felt the other’s ribcage expand with a breath against her back. She felt the frantic drumbeat of two hearts, out of sync, thudding in a shared cavity.
“This is… this is a breach of protocol,” the left one whispered, her voice trembling. The professional jargon was a lifeline, rote and useless. “An… an incident.”
“An incident?” the right one hissed, her head turning to try and see more of their shared body. “Look at us! We’re… we’re fused.” The word was a sob.
Memories flooded them, unowned and shared. The sting of her father’s belt. The dusty smell of the teacher’s lounge. The long, empty nights in her apartment with only the TV’s blue glow for company. The deep, buried loneliness she tended like a secret garden. It was all there, reflected and known by the other. There was no hiding. No armor. The blazer, the skirt, the clipboard—all were gone. All that was left was this raw, doubled flesh and the shocking vulnerability of being truly, completely seen.
They shuddered as one.
A low, wet sound bubbled up from their joint core. A grotesque, shared stomachache. The right Ms. Smith groaned. The left one pressed a hand to her own identical, cramping abdomen.
“What’s happening?” the left one pleaded, her stern demeanor shattered.
Before the right one could form a lie, a tremor ran through the floor. Down the endless white hallway, the lights began to flicker, and the tik-tik-tik-tik started again, softer now, a chorus.
It was coming from both directions.
The sound was a wave, building, a cascade of clicking chitin that filled the sterile air until it was the only thing that existed. It wasn’t just from the ends of the hallway anymore. It came from the walls themselves, from the seams in the floor, from the vibrating panels of the ceiling. The light above them buzzed and died, plunging their section of the corridor into a twilight broken only by the eerie glow of the emergency strips along the floor.
“Move,” the left Smith gasped. It was an order, the last shred of command.
“How?” the right Smith screamed back, their shared legs trembling under them. Every impulse was a argument. The left side tried to lurch forward, the right side tried to brace. They swayed, a grotesque metronome, and almost fell again. The humiliation was acid in their shared throat.
They had to move. The tik-tik-tik was inside their skulls.
The left one closed her eyes, shutting out the mirrored proof of their condition. “Right leg. Now. With me. On three.”
“Don’t you dare count—”
“One. Two. THREE.”
They pushed. It was a staggering, stumbling thing, more of a controlled fall than a step. Their four arms windmilled, grabbing at each other for balance, fingers digging into identical forearms. The touch was a shock—her own skin, but not. The familiar feel of her own slight muscle, the dry texture of her own elbow, but charged now with a foreign will. It was like holding a stranger who knew everything.
Another step. Then another. They were moving, a clumsy, two-headed crab scuttling down the hall. Their shared center of gravity was a foreign country, its laws unknown.
A shadow dropped from the ceiling ahead. Another of the angular creatures, its blade-humming at a different, dizzying pitch. It landed on the floor between them and the turn they were desperately trying to reach.
They froze.
The creature didn’t charge. It observed, its multifaceted eyes catching the low light. It tilted its head, the movement utterly alien.
“Back up,” the right Smith whispered, her voice tight.
“There’s more behind us,” the left Smith breathed. She could feel the vibrations in the floor through the soles of their shared feet. She was right. A glance over their shoulder showed another three of the things emerging from a vent, their blades sketching thin lines of reflected red light in the gloom.
They were surrounded. Naked. Split. The protocol for this was not in any binder.
A harsh, digital crackle split the air, making them both flinch. A speaker grille they’d never noticed hissed to life above them. The voice that came out was flat, synthesized, and utterly calm.
“CEREA NEXT. Phase one assimilation nominal. Specimen S-22 bifurcated. Neural synchronization in progress. Containment breach alert. Initiating clean-up protocol.”
The words meant nothing and everything. Assimilation. Bifurcated. Clean-up. The creatures took a step forward, in unison.
The calm voice came again. “CEREA NEXT. All non-essential biological material will be recycled.”
The left Smith looked at the right Smith. In two sets of identical eyes, the same realization dawned. The deep, buried loneliness, the rigid discipline, the years of being essential—it was all gone. They were non-essential biological material. Now.
It forged a truce. Desperate and immediate.
“The door,” the left one said, nodding her head toward a service hatch barely visible in the wall to their left. It was marked with a faded yellow triangle.
“It’s twenty feet. Through them,” the right one replied, her voice shaking.
“Then we go through them.”
They didn’t count this time. They just moved. A shared, screaming lurch toward the hatch. The creature directly ahead skittered to meet them, its blade rising.
Instinct took over. The right Smith swung a wild, open-handed slap at the thing. It was a useless, human gesture. The left Smith, following the momentum, brought their shared knee up in a brutal, jerking arc. It wasn’t coordinated. It was chaos.
The knee connected with the creature’s body just as the blade swept out. A line of fire opened across their right thigh—a shallow, stinging cut. The creature was knocked sideways with a sound like breaking ceramic.
They didn’t stop. They fell against the hatch, four hands scrabbling at the release lever. It was stiff. The creatures behind them were closing, a skittering tide of polished darkness and humming light.
“Together!” one of them shrieked—they didn’t know who. They both threw their weight against the lever.
With a metallic shriek, it gave.
The hatch swung inwards into impenetrable
With a metallic shriek, it gave.
The hatch swung inwards into impenetrable black. They fell through, a tangle of their own limbs, and landed hard on a grated metal floor. The hatch slammed shut behind them, cutting off the ticking, the hum, the sterile light. Darkness swallowed them whole.
For a moment, there was only the sound of their four lungs hauling in air, the twin heartbeats pounding a frantic, uneven rhythm in their chest. The air here was different. It was warm, humid, and carried the greasy scent of machine oil and ozone.
“Are you hurt?” the left one whispered. Her voice was raw.
“My leg. The cut.” The right one shifted, and a jolt of pain shot through their shared nervous system. They both hissed. “Our leg.”
“We need to stop saying ‘our’ everything. It’s… it’s making it worse.”
“What would you prefer? My half of the leg? Your attached torso? This is anatomically definitive, Helen.” Using her own first name felt like a violation. It was a weapon.
The left Helen—no, the Smith on the left—flinched. “Don’t. Just don’t.”
A faint, pulsing glow began to permeate the darkness. It came from below. They were on a walkway, a catwalk. Slowly, clutching each other for balance and grimacing at the necessity, they got to their feet. They looked over the railing.
The room below was vast. It wasn’t a maintenance closet. It was a laboratory, but one designed by a fever dream. Organic-looking conduits pulsed with violet light along the walls. In the center of the room, suspended in a column of liquid amber light, was a figure.
It was a young woman, or something shaped like one. Her skin had a pearlescent, almost ceramic quality. Long, hair-like filaments floated around her head in the energy field. She was unconscious, her face serene. Tubes and wires connected her to the machinery below.
“God,” one of them breathed.
Scattered around the chamber floor were glass cylinders. Each contained a figure in a state of… modification. One had multiple arms, fused at the shoulders. Another seemed to be halfway merged with a shimmering, geometric crystal. They were still, suspended in clear fluid.
“This is the cultural exchange,” the right Smith said, her voice hollow with disbelief. “This is CEREA NEXT.”
A console near them flickered to life, screens scrolling with lines of biological data and shifting fractal patterns. A live feed showed another hallway, empty and white. A label read: SECTOR 7 - INTAKE.
A door in that faraway hallway slid open. A girl walked in. She was young, maybe nineteen, dressed in the standard issue gray tunic of a new arrival. She had a name tag: CEREA. She looked nervous, hopeful, clutching a small digital tablet to her chest. She was looking for the orientation room.
From a ceiling panel directly above her, the angular creature dropped. It landed on her shoulders. She didn’t even have time to scream.
The blade, that humming sliver of light, flashed. It didn’t cut across her waist. It cut down, vertically, from the crown of her head, straight through her body.
Cerea didn’t bleed. She fissured. A crack of brilliant white light split her from head to groin. For a second, she was a statue of a girl, perfectly cleaved. Then, with a sound like shattering quartz, the two halves fell apart. They didn’t collapse into meat and bone. They melted, reforming as they hit the floor, into two smaller, identical, perfect copies of the original girl. Both naked. Both staring at each other with the same stunned expression before a hidden panel opened and robotic arms swiftly collected them, carrying the two new, weeping Cereas away.
The screen blinked. PROCESS: BIFURCATION. STATUS: SUCCESS. SPECIMENS C-1 & C-2 STABLE. TRANSFERRING TO COALESENCE BAY.
On the catwalk, the two Ms. Smiths watched, their four hands gripping the railing. The shared nausea was a physical wave. This wasn’t an accident. This was the program. The cultural exchange was a feedstock. They were just… material.
“They’re splitting everyone,” the left one whispered, horror drying her mouth.
“They split us,” the right one corrected, the truth cold and absolute. “We’re not coordinators. We’re specimens. S-22.”
A new alert flashed on the console. A red icon pulsed over a camera view of the hatch they’d just come through. It showed the creatures gathering, their blades beginning to spin, aimed at the hatch’s seams. A drilling sound, high-pitched and vicious, started to echo through the metal.
“They’re coming through,” the left Smith said, panic tightening her voice.
“We can’t go back.” The right Smith looked down at the lab floor, at the silent, monstrous machinery. There was another door on the far side. “We have to go down. Through that.”
“Are you insane? That’s the processing floor!”
“And that’s a cleaning crew!” She jerked a thumb back at the shuddering hatch. “Pick the nightmare that doesn’t involve being ‘recycled’ by bug-robots!”
The logic was terrible and inescapable. They began a shuffling, agonizingly slow journey along the catwalk, searching for a ladder, a staircase, anything. Every step was a negotiation, a fight against their own conflicting balance. The drilling grew louder. A tiny, focused point of light appeared in the center of the hatch door.
They found a ladder. It was narrow, barely wide enough for one person. They stared at it, then at their conjoined form.
“This is impossible,” the left Smith moaned.
“It’s a ladder. We go down. We just… do it together.” The right Smith reached out, gripped a cold rung. “You have to mirror me. Exactly. Left hand, I go. Right hand, you go. Understand?”
It was a slow, terrifying descent into the glowing heart of the lab. They moved like a single, wounded animal, each rung a victory of shuddering cooperation. The pain in their leg was a bright, sharp thread. The smell of ozone grew stronger, mixing with a sweet, cloying scent that might have been antiseptic or something biological.
They reached the bottom just as, high above, the hatch exploded inwards in a shower of sparks. Angular shapes poured through the opening, skittering onto the catwalk.
They didn’t look back. They staggered across the lab floor, passing the silent, fluid-filled cylinders. The pearlescent woman hung in her beam of light, oblivious. The door was there, a simple push-bar emergency exit. Hope, thin and desperate, flickered.
They slammed into the bar. It didn’t budge.
“It’s locked! Of course it’s locked!” The left Smith beat a fist against it.
A smooth, synthetic voice filled the chamber, emanating from nowhere and everywhere. “Specimen S-22. Bifurcation anomaly detected. Neural synchronization incomplete. You are non-compliant. Return to your designated containment bay for recalibration.”
On the catwalk, the creatures reached the ladder. They began descending, not one by one, but flowing over it like a single, many-legged entity.
The right Smith looked around wildly. Her eyes fell on the main console near the suspension chamber. A physical key—a thick, brass-colored thing—was inserted in a slot. A label glowed beside it: MANUAL OVERRIDE - MAINTENANCE ONLY.
“There!” She pointed.
It was twenty feet across open floor. The creatures were halfway down the ladder.
They ran. Or they tried to. It was a lurching, sideways scramble, a dizzying mess of conflicting motor signals. They fell, twice, skinning the palms of four hands on the rough floor. They could hear the delicate tik-tik-tik of the creatures hitting the ground behind them.
They reached the console. The left Smith grabbed the key. The right Smith shoved at the override switch. Nothing.
“The key has to turn first, you idiot!” the left Smith yelled, fumbling.
“We’re the same idiot! Turn it!”
She turned it. A heavy clunk reverberated through the floor. The right Smith slammed the switch upwards.
Every light in the chamber flared a blinding white. The column holding the pearlescent woman flickered and died. She dropped, limp, into the receiving apparatus below with a soft thud. All the cylinders hissed, their seals breaking open with gusts of cold vapor.
And the door ahead of them clicked.
The creatures were there. Three of them. Six feet away. Their blades were raised, humming chords of deadly light.
The two Smiths looked at each other. In that shared, frantic glance, an agreement passed. No words. Just necessity.
They turned and hurled themselves at the door, a single, desperate mass of shared fear.
CEREA GETS SPLIT
