The Clogged Valves

Why had the secondary boiler line gone cold thirty minutes before the shift change? Chief Engineer Berglind swung her boots onto the iron grating of the Deck Four gantry, her leather tool harness clinking with brass-headed wrenches and lead-weighted calipers. She needed four hundred pounds of live manifold pressure restored to the pneumatic blowers before the overhead carcass conveyors seized entirely. If the main steam loops stalled out, the sulfurous sterilization mist in the aerosol pipes would condense into tepid water, leaving every man on the lower cutting floors naked against whatever rot was festering in the northern pens.

She unclipped a brass sounding hammer from her belt and tapped the high-pressure return pipe running along the catwalk wall.

Instead of the sharp, ringing chime of dry, pressurized superheated vapor, the iron casing produced a dull, sodden thud. Berglind pressed the flat of her palm against the flange. The metal was barely lukewarm. Condensation dripped from the riveted seams, pooling with dirty machine grease between her boot heels.

"Incompetent grease-monkeys," she muttered under her sulfur-mask, adjusting the strap where the vulcanized rubber pinched the bridge of her nose. "Give them twelve valves to balance and they flood the separator within two hours."

She pulled a pair of dual-needle pressure calipers from her chest pouch and locked the test prongs into the diagnostic petcock above the junction. The main line read sixty pounds per square inch—barely an eighth of standard operating draft. Worse, the return vacuum was pulling backward toward the central control booth at the far end of the gantry.

The silence on the upper catwalk was wrong. By standard operating protocol, Deck Four's steam exchange was the loudest corner of the entire Skallagrim citadel. The rotary blowers should have been screaming like trapped swine, forcing thousands of cubic feet of hot, yellow chemical aerosol down into the slaughter chutes. Instead, the only audible pulse was a wet, rhythmic thumping that vibrated through the floor plates, entirely out of phase with the reciprocating pistons of the primary dynamo.

Berglind unholstered an eighteen-inch pipe wrench and moved down the narrow gangway. Below her, through the expanded metal mesh, the cavernous dark of Deck Three stretched out in vast shadows, broken only by the intermittent orange flare of dying gas lanterns. Further down, near the loading bay, a deep rumble echoed through the masonry flues—the distinctive, grinding crunch of a major structural collapse.

"Kolskegg's butchers are wrecking the floor again," she remarked to the empty corridor. "And they'll try to bill Engineering for the bent girders."

The joke went flat in her throat when she reached the blast door of the Deck Four Steam Exchange.

The heavy steel bulkhead had not been locked by its manual latch. A dense, fibrous lattice of gray gristle and calcified tendon was laced across the seams, anchoring the iron door to its frame. Droplets of clear, oily fluid dripped from the strands, sizzling where they touched the hot copper grease-lines. The meat had woven itself directly into the gear-teeth of the manual override wheel, drying into a hard, gristly cement that held the spokes rigid.

Berglind stepped closer, raising the storm lantern hooked to her breastplate.

Inside the glass viewport of the control booth, the brass dial faces of the master switchboard were visible. Every regulator needle had been pinned into the red. Across the steel floorplates inside, scorched electrical burns and dark sprays of blood marked where the second-in-command and his squad of six Watchmen had made their stand. Their bodies had already been absorbed into the swelling lattice, half-buried beneath pulsing layers of connective tissue with only brass guard buttons and cracked visor glass protruding through the gristle. The copper control levers had not sheared off from mechanical strain. Broad ribbons of striated muscle had wound around the handles, pulling the relief valves shut and lashing them down with fused sinew.

This was not an equipment failure. The biomass was not merely spreading through the overhead conveyor rails; it was systematically choking the factory's thermal loops. By killing the superheated steam, the entity was neutralizing the aerosol sulfur blowers across the entire upper sector, stripping away the only chemical barrier that kept mutated carcasses from recombining.

A cold prickle ran across her neck beneath the heavy leather collar. She reached for the oxygen regulator on her hip, checking the seal. The Directorate safety manuals mandated five minutes of stamped municipal paperwork before venting a live line that could scald the shift alive, but nobody had written an addendum for pipes that sprouted muscle.

She wedged the tempered jaw of her pipe wrench between the doorframe and the petrified meat-lattice. Setting her boots against the corrugated wall, she threw her entire weight against the iron handle.

The gristle gave way with a wet tearing sound, like wet canvas ripping over rusted nails. A blast of rancid, humid air rolled out from the gap, thick with the stench of spoiled beef and boiled bone. Berglind shoved her shoulder into the iron panel, forcing the bulkhead open three inches—just enough to reach her arm inside toward the secondary emergency relief wheel.

The iron wheel governed the bypass flue. If she could spin the bypass open, the high-pressure reserve in the boiler house would vent directly into the Deck Four manifold, scorching the clogged pipes with four hundred degrees of live steam and burning the gristle out of the switchboard.

Her gloved fingers caught the rim of the wheel. She braced her arm and heaved upward.

The wheel turned a quarter-inch, shrieking against rusted threads, and then slammed to a violent stop. Inside the booth, something shifted in the shadows behind the master console. The ribbons of fibrous meat binding the switchboard tightened with a sickening, hydraulic snap. A counter-torque twisted the iron wheel in her grip with enough force to nearly tear her wrist from its socket.

Berglind yanked her arm back through the door gap, stumbling across the catwalk grating.

The relief wheel spun backward on its axle, spinning freely until the valve clattered shut and locked into place. Through the observation window, the brass needles shuddered and dropped to zero. The last thermal circuit feeding Deck Four had been cut.

Above her head, deep within the rectangular sheet-metal duct of the central exhaust shaft, an iron hinge screeched.

Berglind flattened her back against the bulkhead, her heavy spanner raised in both hands. The sulfurous mist in the gantry had dissipated completely now, leaving only cold, damp air that smelled of old blood and tallow.

A wet scrape echoed along the galvanized ductwork. Through the rectangular grate ten feet above the catwalk, an object slipped loose and dropped through the iron mesh, striking the deck with a sodden thud.

Berglind lowered her storm lantern.

The severed forearm on the floorplates wore the soot-stained sleeve of an engineering apprentice, its dead fingers locked around a six-pound iron guild spanner. Braided around the wrist was a band of black, fibrous gristle, pulsing with slow, rhythmic contractions that matched the vibration of the overhead rail.

She picked up the spanner, wiping the black grease across her leather apron. Her maintenance crew was gone, the secondary blowers were dead, and the main steam line to Deck Three would freeze within twenty minutes. Turning her back on the clogged booth, Berglind hooked the heavy iron tool to her harness and started climbing toward the emergency gear train.
