Tetherfall

The harbor smelled like rain on hot metal: salt, diesel, and the faint copper tang of burnt circuits. Neon signs bled down the sides of stacked barges, painting the damp decks in bruised blues and pinks. Cass Calder rode the outer rail of her rig like a surfboard, the salvage harness singing against her ribs with every hard cut of wind. Below, the city’s spine — that thin tether of light running up into the smog — throbbed with a pulse that said the night was awake and dangerous.

She dropped into the cargo maw with practiced ease, boots sparking off a rusted hatch that gave a sound like a gunshot. Water hissed underfoot. A crate sat half-submerged, barnacles like teeth around its seam. Cass jammed the prybar, felt the give of old screws, smelled wet plywood and something sweeter: overheated pressure coils. Her gloved fingers brushed a metal case inside. It fit in her hands like a heartbeat.

Someone screamed — not a human shout but the high keening of a surveillance drone. Lights from a corporate skiff carved through the fog above the waterline. Engine throttles rasped. The skiff dipped, and a small drone fell, sparks trailing as if an ember had severed its tether. It hit the water, tossed by a wake, its casing cracked open. Cass didn’t think; she moved. The harness wrapped around her hips and the rig’s winch took her weight as she lunged, fingers closing on plastic and circuitry.

The drone shivered in her palms. A blue lens blinked like a blinded eye. A child's voice — thin and synthetic — said, 'Please. Keep. Safe.' Cass felt something around the drone slide into her palm: a tiny lattice of glass and light, warm despite the cold air. It flashed with a map fragment and a line of code that tasted wrong in her mouth. The skiff’s searchlight found her. A silhouette stood in the bow with a long coat, a face half-hidden under a visor. A voice came down in a calm that contained teeth.

'Drop it and step away, Calder. You know how this ends.'

Cass grinned even though her throat had gone dry. Her hands tightened. 'Not tonight.'

She clipped the drone to her chest and kicked out, launching herself into the choppy water. The harness yanked, the rig’s thrusters complained, and she felt the bite of speed as she skated along the top of the harbor, neon flares reflecting in wake like errant stars. Behind her, the skiff turned, and a burst of tracer slashed a mast. Planks exploded into the air. Electrical thunder rolled across the water. She heard the skiff’s voice again, closer this time: 'Marla Voss. Surrender the package.'

Cass glanced down at the drone’s cracked lens. Inside, a tiny cluster of light blinked on — not a signal but a face. It was a construct of code and childish cadence. 'Name: Pip,' it said. 'Find the spine.'

She swallowed. The word hit like a coin in a locked slot. The spine was everything.

She hauled herself up a ladder that smelled of frying oil and old sweat, the harness scraping like a second skin. Fingers numb, she ducked into the shadow of a maintenance alcove where a string of dying bulbs cast long, sickly shadows. Pip vibrated against her sternum, its casing whispering. '— danger —follow—' it stuttered, then fell silent as Cass tightened her jacket. The harbor around them was a mouthful of sound: a generator coughing, feet thudding on metal catwalks, a child laughing somewhere deeper in the docks.

Cass kept moving. The Hollow — where she lived — was a hodgepodge of cargo containers, grow-lights, and makeshift shops tethered on pylons. People clustered in doorways, wolfing down noodles, mending nets. Some looked up as she passed, eyes like measurement scales — curiosity angled with wariness. She'd earned that look: a reputation stitched from nights spent stealing what others couldn’t risk and doing favors for favors. She could slip into a crowd and draw a bead on a target or vanish with a crate no one noticed missing.

Her apartment was a loft wedged between a dispensary and a shop for motorized pigeons. Inside, the room smelled of oil and green tea. A workbench groaned under a mess of coil cores and stripped servos. Pip curled on an overturned coffee tin and blinked at everything like a solemn cat.

'You can’t keep me,' Cass said, though nothing in her face betrayed how tightly she’d sewn the words to her chest. She didn’t notice the wet smear of red on the corner of the workbench until she touched it. It was Juno’s blood. Her hand trembled.

'You brought trouble,' a voice said from the doorway. Juno slumped against the frame, her jacket torn and a bandage rough around one forearm. A smear of soot tracked up her cheek like a badge.

Cass sat down hard. 'They followed me.'

Juno laughed, a thin thing without humor. 'They followed Pip. They tracked the tag. You grabbed something that belongs to the Spire, Cass. The Corps doesn't pursue scraps by accident.'

A low hum from the street crawled up the metal ribs of the building. People on the dock muttered, and somewhere, a bell clanged: a routine power check that kept everyone honest. The Hollow’s grid stuttered. Light in the alley hiccupped. Cass felt the hair at the back of her neck rise.

Juno's eyes caught the drone. 'Where did you get her?'

Cass set Pip on the table. The face in the lens rearranged itself into something like a smile. 'Map segment acquired. Spine unstable.'

Juno's breath left her in a short, sharp pull. 'If the Spire goes quiet, the tether fails. Sectors go dark. Pumps fail. People drown.'

Cass pressed her palms to the table, feeling the tremble of that future under her fingertips. The harness beside her felt suddenly heavy, like a chain.
