Drone Deliveries

A dull, rhythmic buzz rattled against the interlocking stone plates above Kjellmar's head, distinct from the steady hiss of the refinery boilers below.

Kjellmar sat cross-legged in the soot crater, adjusting the straps of his reinforced respirator. Inside the sealed vault of Ravnsk's wings, the air was warm, thick with the smell of scorched sulfur and powdered basalt. A single seam of gray daylight cut through the apex where the gargoyle's primaries failed to mesh completely.

Ravnsk had not moved for twenty minutes. The beast remained perched in a low, protective crouch across the rim, his snout resting inches from Kjellmar's heavy work boots. Every slow exhalation from the creature's nostrils sent a puff of stone-dust across Kjellmar's lead-lined knees.

The buzzing grew sharper, accompanied by the tinny whine of an overtaxed electric motor. A brass-plated inspection drone, no larger than a lard kettle, squeezed through the upper gap in the basalt feathers. It wobbled drunkenly into the enclosure, twin propellers kicking up a swirl of black flakes before leveling out two feet above Kjellmar's nose.

Suspended from the drone's belly by copper wire was a greaseproof canvas satchel. Stenciled in sloppy white grease-paint across the side was an arrow and the crudely drawn likeness of a spanner.

Kjellmar caught the satchel by its bottom seam, steadying the erratic machine with his other hand. The drone hummed in relief, its tiny electric coils glowing orange in the gloom.

"Keep it down," Kjellmar muttered under his mask, glancing at the slumbering mass beside him.

Ravnsk's left ear twitching was the only response. A low, gravelly vibration rolled through the gargoyle's chest, but the eyelids stayed shut.

Kjellmar untied the wire and unbuckled the satchel. Inside sat a brass canteen wrapped in wet burlap, a dense block of chilled mutton tallow wrapped in wax paper, and a torn sheet of requisition card covered in Freyvund's jagged handwriting.

He pulled down the respirator mask to bare his cracked lips, then unscrewed the canteen. The water tasted of iron piping and cistern scale, but it cut through the foul sulfur coating on his tongue like a clean razor. He took three measured swallows, resealed the mask over his face, capped the tin, and unfolded the card.

Stennar brought in the municipal extermination crew, the note read. They are wheeling two pressurized cylinders of chlorine-sulfide into the basement flues right now. The guild refuses to pay Tier Four wages to a hostage on a broken chimney. If you are not off that stack in twenty minutes, they are tripping the draft fans and flooding the column with green gas. Grab the drone harness. It won't lift you, but the winch line can drag you onto the roof of Boiler Four if the beast lets go.

Kjellmar folded the card and shoved it into his inner jacket pocket.

A municipal gas purge was standard procedure for clearing vermin nests and obstinate blockages from industrial flues. It was also lethal to anyone trapped at the exit point within sixty seconds of valve release. The guild would file the report as an unavoidable industrial casualty, deduct the cost of the gas from his final paycheck, and close out his pension account before the morning shift ended.

"Twenty-two years of steady contributions," Kjellmar said softly to the dark stone. "Wiped out by four liters of green smoke."

He unwrapped the mutton tallow. The fat was cold and stiff, rendering a greasy sheen onto his calloused thumbs.

He could not pry open three tons of living basalt with his bare hands, and attempting to scramble through the upper vent would wake Ravnsk before his torso cleared the rim. His only lever was chemistry.

Kjellmar pulled his work gloves off and rubbed the chilled mutton fat vigorously between his palms. The friction warmed the tallow, breaking down the heavy triglycerides into a soft, malleable paste. As his skin heated, his own sweat glands responded, secreting trace amounts of modified steroid chains into the grease.

He took a slow breath, centering his pulse to avoid the adrenaline surge that had ruined his concoction twenty minutes earlier. This was not panic. This was standard vat work, calibrated to ambient chimney drafts.

He needed a pure isovaleric sedative array—the heavy, sweet, curdled profile of deep biological dormancy. It mimicked the natural chemical markers a gargoyle pack emitted during a six-month winter hibernation.

The mixture warmed under his rhythmic palms, releasing a pungent, musk-heavy vapor that smelled of damp cellar earth and fermented milk. The humid updraft from the stack flues caught the scent, concentrating it within the wing-vault.

Kjellmar leaned forward on his knees, holding his coated palms six inches from Ravnsk's flared nostrils.

The gargoyle's breathing hitched. The nostrils widened, drawing in a long, deep draft of the vaporized paste.

For three agonizing seconds, nothing happened. Ravnsk's stone jaw remained clenched, the sharp ridges of his brow furrowed in territorial vigilance.

Then the tension snapped.

A massive, shuddering sigh tore through the beast's ribcage. The rigid basalt muscles along Ravnsk's shoulders slackened, sagging inward like softening asphalt under a hot sun. The gargoyle's heavy head dropped entirely, resting its massive snout flat against the soot basin with a dull thud.

Above them, the interlocking wing dome shifted. The basalt plates slid apart by several inches, loosening their airtight lock and letting the cool morning wind sweep through the nest.

Kjellmar wiped his greasy hands on his rubberized overalls and pulled his work gloves back on, then checked the tight seal of his reinforced respirator. The sedative array had worked. Ravnsk's chest rose and fell in the deep, sluggish rhythm of torpor.

The drone hovered five feet up, its copper extraction cable dangling in a loose loop just above the widened opening in the wing canopy. Through the widened basalt gaps, Kjellmar caught a quick glimpse of the refinery yard below: two hundred feet down, the pulverized splintered oak and bent brass plates of the company payroll cart still lay scattered across the cobblestones where Ravnsk had crushed it. Beyond the yard, the tin roof of Boiler Four waited, empty and gray.

Kjellmar rose to a crouch, keeping his boots light against the loose masonry. He reached up, fingers brushing the cold metal ring of the extraction line. If he clipped the cable to his hazard harness, Freyvund could winch him across the thirty-foot gap to the roof of Boiler Four before the gas purge reached the upper stack.

His fingers closed around the ring.

A heavy, grinding scrape cut through the silence.

Before Kjellmar could pull the harness clip, a thick cord of flexible basalt whipped across the floor of the nest. Ravnsk's tail, tipped with a triangular ridge of raw granite, looped twice around Kjellmar's left boot and snapped taut against his ankle.

Kjellmar jerked backward, his grip slipping from the brass ring. The drone shot upward with an angry whine, propeller wash dusting his visor with soot.

He looked down. Ravnsk remained in deep torpor, snout buried peacefully in the ash, but the granite-tipped tail held Kjellmar's ankle with the unyielding weight of an anchor chain. Attempting to pull free would only shatter his tibia against the coping stones.

Escaping on a six-gauge copper wire had always been a long shot. Three tons of territorial stone had claimed this chimney, and the incoming purge meant they had less than a minute before the stack filled with lethal poison.

Kjellmar waved a soot-stained glove at the hovering machine, sending the drone retreating back into the gray smog toward Boiler Four. He could not run, but he was not about to choke on municipal gas while his captor snored through the shift.

He braced his boots against the masonry, hooked both arms beneath the slumbering gargoyle's stone neck, and hauled with everything he had.

"Wake up, you heavy bastard," Kjellmar grunted, digging his heels into the soot as the first acrid trace of chlorine stung his filters. "They're gassing the nest."
