In the old world, they called it the "Apex Protocol." It was meant to be the end of human frailty—a biological rewrite that allowed cells to regenerate as fast as they were damaged. A world without scars. A world without aging.
But science has a habit of demanding a price it forgets to mention.
The spread wasn't a sudden explosion; it was a slow, terrifying realization. The "Metabolic Fire" required to fuel this new, hyper-accelerated evolution was a starving god. To keep the body from eating itself, the host needed live cells—fresh, raw, and coursing with bio-electric life. When the world realized that the infected were looking at their neighbors not as people, but as "Cellular Reserves," society didn't just collapse. It was harvested.
The Lower Wards were a monument to that harvest.
Kaelen moved through the shadows of the North Wing, his respirator hissing—a rhythmic, mechanical reminder that he was still "pure." In his tactical belt sat a heavy, pressurized cylinder—a Bio-Decoy. It was standard issue for facility technicians, containing a pressurized suspension of live cells meant to distract the hungry long enough for a human to escape.
He rounded a corner, his flashlight cutting through the gloom. The beam hit a wall of rusted cooling fins and landed on a figure crouched in the dark.
It was Miller. Kaelen recognized her instantly from the lab—though the woman he remembered would never have been able to squat atop a reinforced steel crate with such predatory stillness.
As the light hit her, Miller didn't scream. She didn't spring.
Instead, she began to turn her head. It was a slow, agonizing movement. Her shoulders remained perfectly still, facing away from him, but her neck twisted with a series of wet, muffled clicks. She rotated her head further than any human anatomy should allow, until she was looking almost directly over her own shoulder, her chin hovering above her spine.
The skin beneath her eyes was a bruised, angry crimson. Her amber pupils were already gone, replaced by a slate-gray that bled into a void-black dilation. Her eyes were deep, hollow pits that seemed to sink back into her skull as they locked onto Kaelen's heat signature.
"Hey... Kaelen," she whispered.
The voice was thin, mimicking a greeting from a life she no longer possessed. It was a haunting echo of humanity used as a predatory lure.
The metal crate beneath her fingers suddenly groaned. With a sound like a gunshot, the heavy steel rivets popped. She didn't have "super strength" in a magical sense; she simply had a body that had removed the neural limiters. Every muscle fiber in her slender arm fired at 100% capacity, and she tore a chunk of reinforced steel away as if it were parchment.
"Miller, stop!" Kaelen shouted, his hand flying to the Bio-Decoy canister.
He slammed the trigger. The canister let out a violent, sputtering hiss—the valve had been damaged. A small, thin cloud of live cells erupted, a pathetic mist in the face of her hunger.
The creature that was Miller didn't just smell the cells; she inhaled with a terrifying, vacuum-like force. In one massive, desperate breath, she sucked the entire cloud of cells into her lungs.
The canister hissed one last time and went dead. Empty.
The "taste" did nothing but fuel her frenzy. Kaelen saw the muscles in her neck cord and tighten. He turned on his heel and bolted.
He slammed through the corridor, his boots echoing against the metal grates. Behind him, he heard the sound of Miller's footfalls—light, rapid, explosive leaps. He dove through the hydraulic doors into the South Building, his hands frantically slapping the "Manual Override."
The doors hissed shut, but the metal began to scream almost immediately. A massive dent appeared in the center of the heavy alloy, then another. Kaelen backed away into the darkness of the South Building, cornered by a maintenance hatch.
The hydraulic doors groaned one last time before the seal snapped. Miller's hand—slender, pale, and coursing with the dark red of the virus—punched through the thick metal door as if it were wet cardboard.
The echo of her voice still rang in his ears, mocking the person she used to be. Kaelen was out of gear, and the cellular debt was about to be collected.
