[University Science Building, Basement Storage Level, Day 3 Post-Skyfall, Morning]
The Science Building smelled different from every other space Ren had moved through since the sky went purple.
Clean. Not clean like it had been cleaned recently, but clean the way sealed spaces stay clean when nothing living has been inside them, antiseptic and chalk-dry, the residual ghost of industrial disinfectant baked into the tile grout over years of use. Formaldehyde underneath that, sharp and synthetic, bleeding from the lab doors on either side of the hall. The fluorescent tubes overhead were dark but the emergency strip lighting at floor level was still running on battery, casting thin red lines down the center of the corridor like runway markers.
No blood. No drag marks. No broken doors.
'Nothing's been in here yet,' Ren thought.
He stood still and let the Tremor Sense read the building.
It was the newest thing in his collection and he was still learning to translate it. It didn't give him images. It gave him vibrations, travelling up through the soles of his feet from the floor and the walls, a physical language of weight and movement. The zombies he had sensed from the stairwell were three floors below, in the basement corridor, roughly six of them based on the rhythm of the footfalls, slow and heavy, clustered near the eastern end.
The heartbeat was further in than that.
Past the corridor. Past whatever doors separated the general basement from the sublevel. It pulsed through the concrete at a frequency that bore no relationship to human biology, too slow, too large, each pulse pushing a tremor through the floor that Ren felt in his teeth.
'Not a person,' he thought. 'But not nothing either.'
"The sublevel," he said. "Is it separated from the main basement?"
Chloe was standing two feet behind him, arms crossed over her chest, pressing her hands against the spider bites on her forearms. Eight small red marks, three on the left arm, five on the right, none of them swelling the way they would have if the venom had gotten proper purchase. Her chestnut hair had come fully loose now, hanging in knots past her collarbones. She had a smear of green spider blood across her left cheekbone that she hadn't noticed.
'He's feeling the floor. He's standing there with his eyes half closed feeling the floor like it's talking to him, and the worst part is I believe that it is.'
"There's a pressure door," she said. "The kind you need a keycard to enter from the corridor side. The chemicals they keep down there are controlled. Nobody goes in without signing the log."
"How many ways in?"
"The keycard door from the corridor. A ventilation access panel on the east wall of the sublevel itself, but it's a forty centimeter square crawlspace. Nothing gets through it."
Ren nodded. He looked at the stairwell door at the end of the hall.
"Stay behind me," he said. "If I tell you to run, you run. You don't ask where."
She nodded.
They went through the door.
The basement corridor had its own ecosystem.
Six of them, as the Tremor Sense had counted. The emergency lighting was out down here, pure dark, and his Night Vision resolved them in grey against grey, slow-moving shapes distributed down the forty-meter length of the corridor between the stairwell door and the heavy pressure door at the far end.
[Mutated Student (Lvl 2)] x4
[Mutated Faculty (Lvl 3)] x2
The faculty ones were bigger. The mutation always seemed to have more to work with in older bodies, more mass to rearrange.
Ren stood at the stairwell door for four seconds and let Eagle Eye map all six positions.
The first student was twelve meters ahead, facing away.
'Start at the far end, work back,' he thought. 'Keep noise minimum.'
He looked at Chloe. He put two fingers up. Then pointed at the floor directly in front of her feet.
Stay here. She understood.
He went.
[Dash Activated.] [Stamina: -5]
Forty meters of dark corridor compressed into a single step. He came out of the blur directly behind the furthest faculty mutant, one hand going to its skull, and drove it face-first into the pressure door hard enough to feel the concrete in the door frame crack. It dropped without a sound.
The other faculty mutant was six meters to his left, turning toward the noise.
Ren crossed the distance at a run and tackled it into the wall, shoulder to its midsection, Strength +3 behind the impact. They hit the concrete together, and he got a knee onto its chest and both hands around its skull and the fight was over in four seconds.
The four student mutants had heard the second impact.
They were converging.
He went through them the way water goes through a gap, fast and direct, using the Dash on the one that was going to reach him first, appearing on its other side and driving an elbow into the base of its neck, and the remaining three were slower and stupider and did not coordinate and he put them down in sequence with his hands and his knees and the heel of his boot, the cast-iron efficiency of a body running on three days of consumed mutation.
The whole corridor took forty seconds.
He stood in the dark and counted his stamina.
[Stamina: 8/20]
He looked at the six shapes on the floor. The familiar hunger was already talking.
'Not yet,' he thought. 'Get through the door first.'
He walked back to Chloe.
She had not moved from the spot. She was looking at the corridor, which was now quiet, which had been loud for forty seconds and was now quiet again. Her heat signature was running hot, pulse visible in her throat.
He held up the keycard.
She exhaled.
The pressure door opened with a pneumatic hiss when he swiped the card, a clean mechanical sound, and the air that came through it was cold and very still and smelled like ozone and stone and something else underneath that he did not have a word for yet. Something mineral and ancient, the smell of deep places.
The Tremor Sense hit him immediately, stronger through the open door, the pulse travelling up through the balls of his feet and into his sternum. Slow and massive and patient.
The sublevel corridor was narrow, six feet wide, pipes running exposed along the low ceiling. Lab storage rooms on both sides, metal shelving visible through small reinforced windows in each door, chemical drums and packaged equipment and sealed containers in orderly rows. The emergency lighting here was still green and functional, casting the whole space in something between clinical and wrong.
At the end of the corridor, the door was open.
Not broken. Open. The lock engaged from the inside.
The pulse was coming from beyond it.
Ren walked the corridor's twenty-meter length and stopped in the doorway.
The room was large for a basement, fifteen meters square, ceiling four meters high to accommodate the equipment racked along the walls. Centrifuges. Cryogenic storage units with green indicator lights. A server rack that was still running, its cooling fans the only mechanical sound in the building. The floor was sealed epoxy resin, smooth and dark, and in the center of it sat a lab chair, the kind with wheels and adjustable lumbar support, and in the chair was a person.
Or had been.
She was young, middle twenties, the lanyard still around her neck reading DR. YUEN, POSTDOCTORAL RESEARCHER, DEPT. OF MOLECULAR BIOLOGY, the photo on the badge showing a woman with shoulder-length black hair, round face, gold-framed glasses, a camera-practiced smile.
The woman in the chair had the same face.
Everything else had changed.
Her skin had gone the colour of raw alabaster, not pale, not fair, the specific lightless white of something that never sees sun, and through it her veins ran in visible blue-purple networks, branching from throat to collarbone to the backs of her hands where they spread across her knuckles in fine geometric traceries. Her hair was still black but it moved without wind, drifting slow and continuous as if underwater, each strand independent. Her frame had remained the person-shaped thing it started as, five-four, narrow shoulders, lab coat still on, but the coat sat differently now, every crease wrong, like what was inside it had subtly rearranged its dimensions. Her hands rested flat on the chair's armrests. Her fingers had lengthened by maybe two centimeters.
Her eyes were closed.
The pulse was coming from her chest. He could feel it through the floor and he could see it, the Heat Sensing rendering her as something his system had not encountered before, not the hot orange-red of living things and not the cold blue of the dead, but a deep violet that pulsed with each heartbeat exactly like the void wraith parasite had pulsed before he ate it.
[Evolved Vessel (???) - Level ???]
The question marks sat in the blue notification text with a serenity that Ren found genuinely irritating.
'Greater than five, probably,' he thought. 'The system doesn't give me question marks for anything I outclass.'
Her eyes opened.
Pitch black. No iris, no white, the entire visible eye filled with the same deep violet-black as her vein traceries, and they oriented to him with a precision that suggested she had known exactly where he was before she opened them.
"You taste different," she said.
Her voice was calm. Academic. The specific cadence of someone who had spent years presenting data to rooms full of skeptical colleagues.
"From the others. Whatever you've been consuming." She tilted her head slightly. One degree. The hair drifted. "Rat. Human. Python. Parasite. Crow. Spider. The profile is extraordinary."
Ren's hand was on the bent knife.
She looked at it. She looked back at him.
"I'm not interested in eating you," she said. "I've been waiting. The system suggested someone was coming."
"What did you evolve into?" Ren asked.
She glanced down at her own hands, the violet vein-web across her knuckles, with the expression of someone checking a document they already know the contents of. "Something the system is still classifying. I haven't left this room since day one. I've been learning what I am." She looked at Chloe in the doorway. Then back at Ren. "Your companion needs the medical supplies on shelf three. Spider venom inhibitor, blue label. I catalogued this room on day two."
Chloe moved without being told, crossing to the far shelving unit with the controlled urgency of someone who had been waiting for a task that wasn't survival.
'She knew. She's been down here cataloguing a storage room and waiting for people to arrive and she knew about the bites before Chloe said a word.'
Ren stepped into the room.
The pulse from Dr. Yuen hit his Tremor Sense at full intensity this time, not dampened by concrete and distance, direct and enormous, a slow rhythmic pressure that moved through the epoxy resin floor and up his legs and settled somewhere between his ribs.
The hunger, for the first time since the closet, did not roar at the sight of something new.
It went quiet.
'Interesting,' Ren thought.
"The system locked your level," he said. "You have question marks."
"Yes."
"Mine doesn't do that to anything I outclass."
"No," she agreed. "It wouldn't."
She stood up from the chair in one continuous motion, the lab coat settling around her, the black hair drifting. She was precisely the height the badge photo suggested, five-four, and she looked at him with those solid violet-black eyes with an expression of complete scientific neutrality.
"I have information," she said. "Floor plans. System data I've been compiling since activation. Mutation patterns. The tower the dragon is occupying." She paused. "I've also been unable to leave this room, because whatever I've become requires approximately four days of stabilization and I have been alone."
"Why tell me this?"
She glanced at the sublevel door, the dark corridor beyond it, the distant sounds of the burning city filtering through the building's bones.
"Because the system put you here," she said. "And because you're the first thing I've encountered in three days that the hunger didn't recommend I consume."
Ren looked at her for a long moment.
He looks at the shelf Chloe is working through, the blue-labeled inhibitor already in her hands, and he pulls the bent boning knife from his waistband and sets it flat on the lab bench beside him, and crosses his arms, and says: "Start with the tower."
