They ran.

  No grace in it. No heroism. Just raw, desperate momentum — feet slapping wet tile, lungs burning, bodies stumbling past their limits.

  The corridor shifted around them as they moved, the building alive and hostile. Heavy metal shutters crashed down over the glass walls like guillotines. Clang. Clang. Clang. Each impact echoed through the narrowing space, turning the open atrium into a funnel, then a choking chute.

  White strobes fired in jagged bursts, searing afterimages into their vision. Behind them, the Halon mist advanced — not a cloud, but a slow, relentless tide, colorless and odorless, swallowing the floor inch by inch.

  “They’re herding us,” Taylor muttered, breath ragged but still wearing that lopsided grin. “Bit rude, yeah?”

  No one answered. No time.

  At the far end, panels irised open with surgical precision. Two sanitation drones stepped out — tall, skeletal, gleaming white ceramic from crown to base. Featureless ovals for faces, clusters of black nozzles where expressions should be. They didn’t hurry. They simply unfolded, arms extending with mechanical certainty.

  “Contaminant identified,” the left one intoned.

  “Initiating scrub protocol,” the right one replied.

  Twin blasts of foam erupted, thick and pearlescent. The first jet slapped the wall beside Taylor, blooming outward, hardening into a rigid, sticky mass like frozen meringue.

  “Sticky,” Taylor said, swerving wide. “Seriously, don’t touch that shit.”

  Marcus dropped into a baseball slide, coat flapping, momentum carrying him under the drones’ elevated firing line. They adjusted aim center mass, but he was already through, rolling up with a savage grin. His casted arm whipped upward, cracking against the nearest drone’s shin. Ceramic split like cheap porcelain. The drone toppled, hollow limbs clattering.

  “Cheap plastic,” Marcus spat as he surged past.

  The second drone compensated instantly, lowering its nozzles.

  Marcus was still in motion, exposed—

  Kam arrived.

  Not a sprint. Not even a run. He simply covered the distance like a freight train finding its stride. Foam slammed into his chest plate, meant to encase and immobilize. Instead it boiled on contact, flash?steaming into a roaring white plume that filled the corridor.

  The drone’s sensors stuttered, optics fogging.

  Kam stepped through the vapor, heat rippling off him in visible waves. One massive hand closed around the primary nozzle. Ceramic blackened, melted, fused shut.

  “Pressure warning,” the drone announced, almost politely.

  The internal tank ruptured with a wet pop. Foam and chemical slurry gushed across the floor. The drone folded in on itself, joints locking, collapsing into a crumpled heap.

  Kam wiped a forearm across his brow, steam hissing off his skin.

  “Stairs,” he said, voice low and gravel?rough.

  ---

  They burst through the stairwell door into cold concrete and echoing darkness. The air here was sharper, almost clean compared to the chemical reek behind them.

  “Floor forty,” Leo called, eyes on the glowing overlay only he could see.

  Taylor leaned over the central shaft. Far below, the Halon mist rose like a living thing, slow but inexorable.

  “That’s bad,” he said. “Down is very much not an option.”

  Maya tilted her head up the endless climb. “Up, then.”

  Kam nodded once. “Roof.”

  They climbed.

  No banter now. Breath came in short, controlled bursts. Words were luxuries they couldn’t afford. Kam’s boots landed heaviest; each impact sent faint tremors through the railing, concrete groaning but holding.

  Leo kept glancing back, worry etched deep. “Your core temp’s spiking hard.”

  “Fine,” Kam grunted.

  “The plate’s trapping too much. You’re throttling yourself.”

  Kam didn’t reply. Sweat beaded under his hood, evaporating before it could fall.

  “Save it for the door,” he said finally.

  Behind them, spider?drones skittered along the walls — small, many?legged things with welding torches for mouths. They sealed each landing door as the group passed, molten sparks raining down.

  “Zone thirty?eight sealed,” the building’s calm voice announced.

  “Zone thirty?nine sealed.”

  The stairwell became a sealed tomb below them.

  They reached the roof access: a heavy steel door, red lockdown light pulsing.

  Locked.

  Kam sagged against the wall, chest heaving. Heat rolled off him in shimmering waves, fogging the air.

  “Door,” Maya said quietly, urgency threading her voice.

  Kam gripped the crash bar. Pulled.

  Nothing.

  For the first time, the building held.

  “Any time now,” Taylor said, glancing down the shaft where mist lapped at the edges of their landing.

  Marcus stepped forward and slapped Kam hard across the face, the sound sharp in the confined space.

  “Wake up.”

  Kam’s eyes refocused, pupils contracting. “Right.”

  He planted his feet, shoulders bunching. Pushed.

  The frame screamed. Bolts sheared. Concrete powdered. The entire door assembly ripped free and clattered onto the roof.

  Cold rain slashed sideways, driven by high wind.

  ---

  They spilled out into the storm.

  Real air — thick with ozone and city exhaust — hit them like a slap. The roar of traffic forty storeys below, neon bleeding into puddles, sirens somewhere distant.

  Kam dropped to one knee, yanking his hood back. Steam poured off him in thick curls, instantly devoured by the downpour.

  Leo watched his readout. “Cooling fast. You’re stabilizing.”

  Taylor edged to the parapet, rain plastering his hair. He peered down the sheer face. “Flying remains off the table, sadly.”

  Maya pointed across the roof. A window?washing cradle hung limp on thick steel cables, swaying in the gale.

  “Controls are dead,” Marcus said, already moving.

  “Hydraulic reserve,” Leo countered. “Needs pressure.”

  Kam rose, water streaming off his coat. He wrapped one hand around the motor’s fluid tank.

  “Hold on.”

  Heat flared again — controlled this time. The fluid expanded; gauges spun. Brakes released with a metallic shriek.

  The cradle lurched.

  “In,” Kam ordered.

  They piled onto the narrow platform. Kam leapt last.

  The sudden weight snapped one retaining bolt. The cradle dropped a heart?stopping meter.

  Taylor yelled something incoherent.

  Kam’s hand clamped onto the main cable. Skin sizzled against wet steel. Sparks showered down in a bright cascade. Descent slowed — jerky, grinding, but controlled.

  They slammed into street level. The cradle buckled sideways, metal twisting.

  Kam took the impact in his legs, knees flexing deep. Concrete spider?webbed around his boots. Steam hissed from his palm where it still gripped the cable.

  Above, the strobes ceased. The building’s voice drifted down faintly through the rain.

  “Sanitation cycle complete. Debris deposited at street level.”

  Marcus spat blood onto the pavement and laughed — short, hoarse, genuine.

  “Debris,” he echoed.

  Kam straightened slowly, rain washing soot and foam from his coat. He looked up the impossible height of the Spire — black tower unchanged against the storm?lit sky.

  “Good,” he said quietly.

  He pulled his hood up, water cascading off the edge.

  “Hard to burn rubbish.”
