Chapter 1: The Corrupted Relic
The air in the lab wasn’t right. It wasn’t just the damp, concrete smell of a place buried for a century, or the ozone-tang of dead electronics. It was thicker. It clung to the back of Marcus’s throat, sweet and chemical, like rotting fruit preserved in formaldehyde.
“Watch your step here,” he said, his voice bouncing off the vaulted ceiling lost to shadow. His boot nudged a pile of brittle bones, still clad in the faded blue rags of a long-dead scientist. “Floor’s unstable.”
Elena moved past him, her own boots scattering dust. “You worry like an old woman.” A grin flashed in the gloom, white teeth against her dust-smudged face. She held her rifle loosely, pointed at the ground, but her eyes were everywhere—darting over the graffiti of rusted piping, the skeletal remains of mainframes, the ominous dark pits where the floor had given way.
They’d been partners for three years, scavengers in the Commonwealth wasteland. Where Marcus saw danger and decay, Elena saw possibility. He was the mechanic, the one who could make a fusion core hum with just a screwdriver and a prayer. She was the hunter, the one who found the cores in the first place.
“Old women live longer,” Marcus muttered, playing his flashlight beam over a bank of shattered glass tanks. Silhouettes of… things… were still visible, floating in murky brine, their forms twisted and unnameable. “This place gives me the creeps. Pre-War bioweapons division. Nothing good ever came out of a place with a decontamination arch.”
“Something good might be left behind,” Elena said, her attention already caught. She’d spotted a dented metal case, military-grade, wedged under a fallen I-beam. It was a miracle the ceiling collapse hadn’t crushed it flat. “Jackpot.”
“Elena, wait—”
She was already there, sheathing her rifle and sliding her fingers into the gap. The muscles in her back tightened under her leather armor. With a low grunt of effort, she braced a boot against the beam and pulled. Metal shrieked in protest, then gave way with a final, groaning sigh.
The case popped open.
Inside, cradled in molded foam that had mostly decayed into black dust, was a single glass vial. It was thick, sturdy, sealed with a heavy-duty rubber stopper and a metal clamp. A faded, yellowed label was still legible in the beam of Marcus’s light: FEV. STRAIN G-113. PROPERTY OF U.S. ARMY.
“Forced Evolutionary Virus,” Marcus read aloud, the words tasting like ash. “We need to go. Now.”
“It’s just a bottle,” Elena said, but her voice had lost its teasing edge. She picked it up carefully, holding it to the faint light filtering from a crack in the roof far above. The liquid inside was a vibrant, unsettling green, swirling with faint luminescence even in the dark. It seemed to pulse. “Heavy. Could trade it. Or,” she turned it over, the green liquid sloshing, “maybe use it as a fancy bottle stopper. Class up the place.”
“Put it down. Seriously. That stuff is the reason the world is full of two-headed cows and super mutants.”
“It’s sealed, Marcus. It’s inert. Look.” She held it up, demonstrating the intact seal. “It’s a piece of history. A really, really nasty piece of history. Might be worth a month of clean water to the right collector.” As she spoke, her thumb, calloused and strong, rubbed over the metal clamp securing the stopper.
There was a tiny, almost inaudible click.
A hairline fracture appeared in the old glass, right at the base of the stopper.
“Elena—”
A hiss, like a sigh of relief after two hundred years of containment. A wisp of vapor, emerald green and unnaturally dense, jetted from the crack.
Then the vial ruptured.
It didn’t shatter. It bloomed. A billowing cloud of viridian mist enveloped Elena’s head and shoulders, so thick Marcus lost sight of her. She stumbled back, a sharp, choked gasp cut off into a wet gurgle. The empty vial fell from her clawing fingers and shattered on the concrete.
“Elena!”
He lunged forward through the dispersing cloud, the chemical sweetness now overpowering, cloying, invading his sinuses. She was on her knees, hands at her throat, making horrible retching sounds.
“Burning,” she rasped. “Marcus… it’s burning.”
He dropped beside her, grabbing her shoulders. Her leathers were hot to the touch. A violent shudder wracked her frame, so powerful it nearly threw him off. A low, pained moan tore from her lips, deepening, warping into something guttural.
“Look at me, just look at me, we’re getting out of here,” he babbled, tears of panic and dust stinging his eyes. He tried to lift her, but she was a dead weight, seizing.
Her skin began to ripple.
It was subtle at first, a trembling in the muscle of her forearm he held. Then it wasn’t subtle. The flesh beneath her skin moved like something was tunneling through it, thickening, darkening. A sickening series of pops and cracks echoed in the silent lab—the sound of bones restructuring themselves under immense, violent pressure.
She screamed.
It was Elena’s voice, layered with a roar that vibrated in Marcus’s chest. He fell back, scrambling away as her body erupted.
Her frame expanded, tendons and ligaments snapping and re-knitting with audible wet sounds. Her clothes split at the seams. Dusky brown scales, hard and pebbled, pushed through her skin, spreading up her arms, down her back. Her fingers curled, bones elongating, dark keratin sheathing them into vicious, curved talons. Her legs wrenched backward, the joints reversing with a horrific crunch into a digitigrade stance. A long, powerful tail, armored with bony plates, smashed into a lab table, pulverizing it.
Marcus could only watch, his mind screaming a denial his voice couldn’t form.
The transformation surged upwards. Her torso thickened, muscle stacking upon corded muscle. Her human breasts swelled grotesquely with her overall mass, a jarring, feminine curve on the monstrous new form. A pair of curved, wicked horns spiraled up from her brow, pushing through her scalp.
And then it stopped at her neck.
The change slowed, receded. The scaling faded into the familiar, soft curve of her jawline. The monstrous growth gave way to her face. Her face. Elena’s face, pale with shock and pain, but unmistakably hers. Her soft brown eyes, wide with terror, found his. Her full lips trembled.
She tried to speak. A deep, earth-shaking rumble emanated from her cavernous chest, the precursor to a voice. She fought for control, the human intelligence in her eyes wrestling with the primal beast of her body.
“M… Marcus?”
The word was a basso profundo growl, halting, strained with a unfamiliar vocal apparatus. But it was tender. It was hers.
She was twelve feet tall. She was a Deathclaw, a legend of pure destruction made flesh. She looked down at her own claws, at the talons that could rend steel, and a low whine of despair rattled in her throat.
Marcus stood up on shaky legs. He didn’t run. He didn’t reach for his gun. He took a step forward, then another, his eyes never leaving hers.
He reached out a trembling hand, ignoring the primal fear screaming in every cell of his body, and placed his palm against the scaled, powerful curve of her arm. It was warm. Alive.
“Elena,” he whispered, the word cracking.
A heavy thud shook the floor. The gigantic Deathclaw—Elena—had collapsed to her knees, her massive head bowing. A single, hot tear, human-sized, traced a path through the dust on her cheek. She nuzzled her impossibly large head against his chest, a gesture so familiar, so her, that it broke him.
He wrapped his arms as far as he could around her scaled neck, holding on, feeling the awesome, terrifying power humming beneath the surface. He could hear the quick, panicked thunder of her heart, a drumbeat of fear.
Then a new sound cut through the silence of the tomb. The distant, echoing clang of a metal door. Voices, human voices, uptalking and laughing, filtered down from a corridor above.
“You smell that? Chemical shit. Told you this wing wasn’t fully cleared.”
Raiders.
Elena’s head snapped up. Her eyes, so human a moment before, instantly sharpened. The pupils narrowed to reptilian slits. A deep, warning growl built in her chest, a sound that made the broken glass on the floor tremble. It was not a human sound. It was the sound of a territory being marked, a threat being assessed.
Her clawed hands, each larger than Marcus’s torso, flexed. She shifted her weight, placing herself squarely between Marcus and the source of the voices. Her tail, thick as a tree trunk, went rigid, the bony tip flicking once with lethal intent.
Every line of her monstrous body sang with a single, ferocious purpose.
Protect him.
Marcus stared up at the creature he loved, at the ravenous beast she had become, and knew with cold certainty that the men coming down the corridor were already dead. He just didn’t know what would be left of Elena once she killed them.
