Project Fenris

The serum Gambit

Steam curled like smoke through broken vents, the air sharp with metal and something burning. Her hand floated near the glass tube, warmth throbbing from inside, that golden fluid softly buzzing. A pull deep in her chest urged her forward - give it to Fenris, watch him rise, unstoppable. But a quiet voice beneath her ribs whispered otherwise. Not medicine. Something waiting.

Stillness gripped Elias, his hands moving like smoke across silence. A warning slipped out - sharp, low. The air tightened around his words. Not yours now. Or them either

Suddenly, Sloane clenched her teeth. Underneath, Fenris pulsed, a rumble rising into her ribs. A single shove, just one contact, and the animal would burst free - wild, unstoppable. Yet the serum whispered balance, sharpness, something like an anchor when the creature threatened to drown her. Risk was the only choice left.

Into the room they pushed, a line of cold metal and sharp movement. Boots on broken ground made sound - steady, repeating, like gears turning deep inside a machine. Light blades cut through air, moving wide across walls, searching without mercy. She breathed once, twice, feeling each thump behind her ribs fall into step with Fenris’s hum. The timing locked in, not planned but there, just like that.

Arthur’s voice seeped through the vents, low, silky menace: “Every choice you make strengthens the chain, Sloane. Every move you think is yours… belongs to me.”

Fenris didn’t speak - his silence snapped like a wire pulled taut. Words had never led anyone forward. They dragged. His jaw flexed, hidden tension humming through his frame. The vial dug into Sloane’s palm, heat glowing behind her stare. Hers now. Not fate’s. Not chance. A turn taken. Power held.

Fenris moved before she did, muscles taut, speed beyond flesh or wire. Her charge met his blur - jaws snapping near blades, missing by less than a breath. The Cleaners stumbled, caught off guard by what they’d misjudged so badly: neither person nor program, but raw edge disguised as form. Claws scraped metal, struck again, each hit like lightning shaped on purpose - wild, exact, deadly in its rhythm.

Not far from her stood Elias, steady as stone, grounding her. Step by step, blow following blow, breath syncing with motion, they flowed like thunder just before the downpour. The Cleaners stumbled, slowed - hope sparked in Sloane’s chest. Then her eye caught the vial trembling slightly atop its stand. Underneath, a thread thin as air pulled tight, waiting to wake whatever trap lay coiled within the Labyrinth.

Everything dragged. Inside her, Fenris bellowed, rage tangled with need. She jumped forward, fingertips just brushing the vial - heat rising from its golden glow like breath before a scream. The line broke with a snap, sending sparks skittering across stone - a snare missed until too late.

Steam burst through splitting panels as the room came alive. From overhead, metal flaps tore loose, spitting debris into the air. Amid the noise, the Cleaners pushed forward - only for Sloane to whirl under Fenris’s strength, slicing with clawed hands, slipping between attacks like smoke given shape. At her side, Elias cut a steady line ahead, each motion tight and exact, refusing any wasted effort.

Falling quiet after that. Stillness took over next.

The glass tube rested in her fingers, golden fluid pulsing with heat. Below, Fenris stirred, low and watchful, waiting without rushing. Yet a change came through the dark corners. Cold pressed down, deeper than stone walls could hold. From nowhere, Arthur moved closer - not seen, yet felt fully, hovering near what sight can catch.

“You took it,” he whispered, voice low and cold, “but did you think it would be that simple?”

Fingers curled into fists. A growl rose - claws out, jaw set, every nerve alive. Her voice cracked like a whip. Fire mixed with poison in her words. The name Fenris burned on her tongue. Rules meant nothing anymore. Power shifted without warning. Now she named each move

Arthur’s laugh was soft, almost fond. “Good. I was hoping you’d say that. Let’s see how far your bloodline will carry you.”

Something stirred once more, though now the walls breathed with purpose. Instead of stillness, movement - shapes sliding, dark coils tightening, beams curving without warning. Not simply stone and steel, but something sharper: Arthur’s edge, coiled in silence, waiting just out of sight, murmuring dangers that stuck like thorns.

Her grip on the vial tightened. Not just glass and fluid in her palm - this weight carried what came next. One path order, another wildness; one breath life, the next something beyond it. Under her skin, Fenris trembled like a struck wire, coiled to rip free. Beside her, Elias stood unmoving. His fingers grazed hers, quiet pressure holding her fast when everything else pulled apart.

The chase was on, true. Yet here came the risk: a single misstep, or else the Labyrinth wouldn’t merely strike back - it would reshape them down to the bone.
