The Breathing Tax
Frost limned the plex shield above Dock Twelve while Ngozi Udeh counted the breaths trapped underneath it. Titan’s dawn cycle washed lavender through the air as Iron Wake haulers idled beside stacked pallets. Relief Wave 744 listed eight crates of oxygen membranes bound for Helios-Beta’s haemolysis ward. Iron Wake had already tagged one pallet for “security tithe” and dispatched their auditor to collect.
Ngozi flattened her palm against the slate to still her pulse. Crate nine held the membranes that would keep transplant survivors alive when the ammonia storms rolled over the dome tonight. Iron Wake demanded three membranes as payment for patrol escorts along the Cascade shipping lane. Losing them meant six patients without air. Refusing meant Iron Wake cutting protection for Solace Corridor entirely.
Chibueze Obi arrived with the last of the night shift. He wore Guild of Stellar Engineers coveralls stained with coolant, an open secret that masked his role inside the Grave Thread Exchange. He set a steaming kav bulb on the crate seal until the pressure frost melted beneath it, a deliberate show of ownership.
“The tithe stands,” he said. No greeting. His gaze stayed on the slate. “Iron Wake requires crate nine scanned out of the manifest before Bianca arrives.”
Ngozi imagined the ward: twenty beds, fourteen working monitors, a fan that clicked more than it turned. “Bianca Flores can read every seal I forge. We cannot lose that pallet.”
“She can also shut this dock until Iron Wake recoups their losses,” Chibueze said. “Grave Thread outriders already warned me. Children of Earth splinters keep probing the Cascade corridor. Without Iron Wake escorts, Relief Wave 745 never leaves Saturn.”
Ngozi scrolled to the hidden layer she had encoded overnight. Crate twelve carried counterfeit ration bricks Saltglass Circuit tried to launder. Crate four held confiscated cascade-reactor filaments. She needed Iron Wake looking everywhere but nine.
“Swap their tithe,” she said. “Crate four gives them filament for hull plating. Crate twelve gives them a villain to punish. Crate nine reaches Helios-Beta untouched.”
Chibueze let out a breath that fogged between them. “Bianca knows four belongs to Marrow Trace. She wants medical stock, not scrap.” He tapped the slate. “Iron Wake keeps Titan alive because Titan pays.”
“Helios-Beta keeps Titan alive because the ward still has oxygen membranes,” Ngozi said. The memory of the Defiant Stand pulsed at the back of her mind: Admiral Chen holding the line above the moon so the Vethrak beacon stayed silent. “Iron Wake swore to protect medical shipments after that battle. A tithe on lungs breaks that oath.”
“Oaths do not move cargo.” Chibueze leaned closer. “You want crate nine free? Buy eight minutes. Grave Thread can plant two diversions, no more.”
Ngozi pictured Dock Three’s maintenance crawl, a frost-choked tunnel that linked to the Ecclesia diplomatic wing. No Iron Wake scanner crossed that sanctum without sparking a riot. If she could drag the pallet through the crawl before Bianca arrived, the membranes would move under ecclesiastical charter. Iron Wake would see a tithe on paper and fumes in reality.
“Give me those eight minutes,” she said. “Trigger a coolant leak near the Kraken Mare pumps and spoof a Saltglass signal in the diplomatic bay. I will swap the crate labels and move nine through the sanctuary.”
Chibueze’s mouth twitched, the closest thing to a smile he ever let slip when business burned. “You owe the Exchange two favors.” He flicked the stylus to life and mapped the diversions with quick strokes. “Iron Wake hates wet drives. The leak will hook them. Bianca still arrives in nine minutes.”
Ngozi signed the route, the stylus biting into the slate hard enough to squeal. “I will file the inspection myself.”
He pocketed the stylus and vanished into the maintenance corridor. Seconds later, amber coolant alarms strobed across the dock. Iron Wake enforcers cursed inside their visors and sprinted toward the pumps. Ngozi kept her expression neutral, the drilled calm of a compliance officer, even as adrenaline sharpened each heartbeat.
She muscled crate nine onto a manual pallet jack and pushed into the crawl. Frost scraped her cheeks. The corridor sloped downward, lined with bundled conduit that radiated faint heat. Halfway through, the jack caught on a missing grate. She wedged her shoulder against the crate and forced it forward, lungs burning under Titan’s thin air.
Grave Thread outriders whispered through the comm about staged leaks and Saltglass ghosts. Ngozi kept moving until the crawl opened into the diplomatic wing. Incense masked the reek of ozone. She swapped crate nine’s label with fourteen, sealed both, and triggered the ecclesiastical charter. Sanctuary caretakers would bless the shipment and shepherd it to Helios-Beta under escort no Iron Wake dare stop.
“Cargo rerouted,” she said over the comm, voice raw. “Ecclesia channel engaged.”
“Iron Wake redirected Bianca toward the diplomatic gate,” Chibueze replied. “She thinks Saltglass hid cascade shrouds inside crate fourteen.”
Ngozi jogged back to Dock Twelve, wiping frost from her sleeves before the airlock cycled. Bianca Flores arrived on cue, visor mirrored, two armored escorts flanking her.
“Inspection,” Bianca said. “We traced a coolant leak to this dock.”
“Already logged.” Ngozi lifted the slate, displaying the falsified seizure order. “Saltglass embedded a counterfeit sensor in crate fourteen to fake contamination and divert relief stock. Exchange outriders flagged it before departure.”
Bianca’s shoulders stiffened. “Saltglass would need diplomatic access.”
“They bribed a pilgrimage handler last quarter,” Ngozi said. “Check the Ecclesia audit. You’ll find the same signature that appeared on those counterfeit ration chips you seized near Kraken Mare.”
The Iron Wake auditor’s silence stretched while the coolant alarms wound down to a thin whine. Finally Bianca nodded to her escorts. “Lock the diplomatic wing. Retrieve crates twelve and fourteen for inspection. If Saltglass touched anything else, I will dock the Directorate’s future allotments.”
“Understood,” Ngozi said. She held Bianca’s gaze. “Helios-Beta still expects Iron Wake to honor their pledge from the Defiant Stand.”
“Iron Wake honors payments,” Bianca replied. She pivoted toward the wing, already issuing orders.
The moment Bianca cleared the dock, Ngozi authorized the sanctuary transfer. The Ecclesia gate swallowed crate nine without protest. Incense smoke curled behind it like a benediction. No Iron Wake scanner crossed that threshold. Helios-Beta’s ward would receive the membranes inside three hours, storms or not.
Ngozi sagged against the pallet jack and let the ache roll down her spine. Eight minutes had stretched to ten, yet the slate still showed the tithe satisfied. On paper, Iron Wake received crate four’s filaments and crate twelve’s counterfeit bricks. In reality, they would chase Saltglass through the diplomatic wing while Helios-Beta prepped new membranes.
“Delivery confirmed,” she told Chibueze.
“Bianca believes Saltglass owes her two crates,” he answered. “She diverted Iron Wake’s auditors off your lane. The Grave Thread Exchange expects repayment once the storms pass.”
Ngozi imagined Sister Hyejin wiping condensation from cracked windows while patients listened to the new membranes hiss. For one night, Helios-Beta would breathe without counting. That was worth any favor ledger.
“Send the bill,” she said. “And remind Bianca—” she stopped, rephrased, “Remind Iron Wake that Helios-Beta remembers who stood between them and the void during the Defiant Stand. They can tax numbers, not memory.”
Chibueze’s laugh crackled over the line, brittle as frozen conduit. “Careful. Memory fuels revolutions.”
“So does air.” Ngozi cut the channel and walked toward the ward. Outside the dome, Iron Wake haulers glinted against Saturn’s rings, engines waiting for the next tithe. Inside, she held one crate’s worth of ground. The Breathing Tax still hung over Titan, but for a single rotation, she had rewritten its terms.
Author’s Note: Titan’s relief economy never healed after the Defiant Stand, so every clinic bargains with syndicates. Ngozi’s “breathing tax” nods to that fallout and the way Iron Wake keeps pressing the system’s choke points.
