The Floor Tax
Kaelen woke to the ventilation meter coughing its last green bar.
The box bolted beside his bunk stuttered, flashed 02:11, and dropped from pale green to a sickly, warning amber. In two minutes and eleven seconds, the sub-basement block would stop paying for air.
This wasn't a metaphor. The Academy stamped every lower-floor breath into a billable allotment, and his floor account was thirty-seven credits in the hole.
He sat up, the room tilting as the air thinned. His terminal glowed on the wall, displaying three notices like blades laid edge to edge:
FLOOR TAX DELINQUENT. SCHOLARSHIP RANK UNDER REVIEW. AUDIT CYCLE CLOSES AT NOON.
Below them, Overseer Lin’s seal pulsed a cold, bureaucratic blue. No personal message. No mercy. Just the kind of administrative weight that could erase a year of work without a witness caring enough to call it cruelty.
Kaelen swung his legs off the bunk. The numbers were worse than he remembered. That was the trick of the Spire: every day, the climb got steeper while you slept. Floors were worth more than years here. A person could lose a level of residence, and with it, clean air, training access, and whatever dignity remained. His scholarship sat one failure away from termination. If Lin marked him noncompliant, the account would freeze. No stipend. No ladder access. No trial eligibility.
01:54.
Kaelen stood, palms flat against the wall, forcing his breathing into a shallow, controlled rhythm. Panic made you greedier with air, and greed made the meter drop faster. He had learned that lesson the night his family’s block collapsed three tiers below, the shaft seals failing while the upper residents complained about the smell and kept eating.
He swallowed the metallic taste of the air and jabbed the terminal.
CURRENT BALANCE: -37.4 CREDITS NEXT PAYMENT WINDOW: 01:49
He had one hour until the audit lock became official. Staying here meant waiting for the ventilation to cut. Moving meant finding leverage.
He grabbed his satchel and stepped into the corridor. It was a place of coughing, muttered curses, and people pretending not to notice the thinning air. A maintenance drone hovered near the ceiling, its red lens ticking from one resident to the next. It paused on Kaelen, measured him, and moved on.
He took the service ramp down toward the refuse corridor, where the lower-floor market dumped what the higher tiers considered damaged. If he could find one stamped relay or a piece of tech the Broker would accept, he might trade it for air credits before the clerk arrived.
Might. The word tasted like rust.
The trench beneath the ventilation line stank of ozone and hot plastic. Broken pressure plates lay in piles like shattered ribs. Kaelen crouched, sorting through the debris by touch. Dead brass. Dead glass. A relay stamp with its authority ridge ground clean—too illegal to carry, too broken to matter.
“Still digging, little scholar?”
The voice drifted from the shadows. The Broker.
“Still breathing, Broker?” Kaelen replied, not looking up.
A dry chuckle echoed. “Barely. Which means I’m doing better than most.”
Kaelen shifted a heap of snapped seal rings and froze. His hand closed around a slab the length of his forearm, black as smoke and etched with a pattern so fine it hurt to look at. It was warm.
He turned it over. A corner was sheared clean, but on the underside, half-hidden by grime, was a stamped warning: BANNED TECH — MARKET INTERFACE TYPE IV.
“You found one,” the Broker whispered.
Kaelen wiped the grime away. The etched lines responded, brightening in a slow, rhythmic pulse. A ledger grid flickered across the surface: MARKET-MAKER // LOCAL VOLATILITY INTERFACE.
“It’s tracking the upper-tier economy,” Kaelen said, his voice tight.
“It’s feeding on it,” the Broker corrected.
The slab flashed, snapping to a new window. SUBJECT: KAELEN, SCHOLARSHIP NODE 44-B. CURRENT SURVIVAL RESERVE: 19 MINUTES 08 SECONDS.
The ledger had mapped him. It had turned his breathing into a tradable liability.
STAKE REQUIRED FOR CALCULATION: 1 UNIT PERSONAL VOLATILITY.
“Risk,” the Broker said. “Exposure. Something the city can measure.”
Kaelen looked at the shard, then at the corridor leading to the exchange kiosk. He pressed the ledger’s edge to his wrist and fed it a sliver of his own circulation. Pain lanced up his arm, but the slab lit up.
STAKE ACCEPTED. VOLATILITY INPUT: LOW. CALCULATION IN PROGRESS.
He felt his circulation pulled through the relic, tightened and sorted. Not lost—repriced.
AIR RESERVE +03:12.
The meter in his pocket jumped. The alarm cut out. He drew a fuller breath, the change immediate and physical.
“It works,” Kaelen breathed.
“It works,” the Broker said, his voice losing its laziness, “if you’re willing to pay in a currency you can’t get back.”
Then, the final line crawled up the slate: SURVIVAL RESERVE DOES NOT COVER AUDIT THRESHOLD. LIQUIDATION IN: 11:28:17.
Kaelen stared at the countdown. The ledger had bought him a path, but it was a path with a price tag. He couldn't survive the audit on breathing alone.
