The Blood Tithe

Obioma did not turn his head immediately. He allowed three full seconds of silence to settle over the dais, listening to the drip of condensation from the vaulted ceiling and the distant, subterranean throb of the overloaded siphons below. Then he turned his gaze slowly toward Warden Ekenna.

The young warden's face was flushed red under his oiled bronze gorget. He had taken half a step forward from his assigned post beside the table, his fingers curled into fists at his sides.

"Warden Ekenna," Obioma said, the words low and heavy. "You have spoken during a formal tribunal session without being addressed by the presiding officer. Explain yourself before I have you stripped of your commission and placed in cradle five."

Ekenna swallowed hard. His throat bobbed above the leather collar of his tunic. When he spoke, he reached instinctively for the formal cadence of the garrison regulations, his voice tight with anxious strain.

"Regulation Forty-Eight, Section Four of the Eastern Span Charter, Overseer," Ekenna said, his eyes darting toward the kneeling weaver and then back to the cedar desk. "Under the labor preservation protocols, an active artisan household that can demonstrate sixty percent fulfillment of their toll may apply for a ten-day labor deferral, provided a bonded warrant is registered with the quarter bailiff. If we drain both adult workers from the Okoye loom tonight, their production ceases entirely. By next month, the household will be completely insolvent, yielding zero coin and zero grain. From a logistical standpoint, granting the ten-day deferral preserves future revenue while extracting sixty percent of the immediate target."

A profound stillness descended on the tribunal. Clerk Obiageli stopped his chalk mid-stroke, his eyes fixed on the damp wood of his desk. The two guards holding Okoye paused, their hands resting on the weaver's shoulders, braced for what was coming.

Obioma stared at the young warden. His expression did not change; it remained the same weathered, impassive mask of gray basalt that had looked down on twenty years of starvation, disease, and siege.

Slowly, deliberately, Obioma lifted his heavy iron cane from the floor.

With a sudden, violent crack of displaced air and crushing momentum, the square pommel slammed into the side of Ekenna's left knee.

The warden gasped, a sharp, choked sound of pure shock, and his leg buckled beneath him. He hit the stone flags with a heavy, clattering crash, his iron gorget ringing against the floor. He scrambled to his hands and knees, clutching his bruised knee, his breath hitching in his chest.

Obioma did not rise. He lowered the cane, resting the pommel back on the cedar desk, the iron tip leaving a small, clean indentation in the polished wood.

"Regulation Forty-Eight was drafted eighty years ago by clerks who had never smelled the ash-wastes," Obioma said, his voice dropping into a register so cold and level that the guards along the wall instinctively stiffened. "Regulation Forty-Eight assumes there is a tomorrow to collect on a deferred bond. The Black Trench has two breaches tonight, Ekenna. The iron-wards in the sub-vault are vibrating at three hundred cycles above their structural tolerance. If the conduits run dry at third bell, the dead will not wait ten days for Master Okoye to finish a bolt of broadcloth. They will break their moorings, scale the inner revetments, and butcher every weaver, clerk, and junior warden from here to the Upper Market."

He leaned forward over the desk, his massive shoulders casting a broad, black shadow over the kneeling warden.

"You have been in the green wool for six months, boy. You still believe that the city is held together by regulations and polite agreements written on parchment. The city is held together by four hundred dead soldiers who require four thousand gallons of human blood every thirty days to keep their fingers wrapped around their spears. Every time you grant a deferral, you are stealing three quarts of oil from an engine that is already seizing on its bearings."

Ekenna remained on his knees, his head bowed, his hands shaking against the damp stone. "Understood, Overseer."

"Get up," Obioma commanded.

Ekenna pulled himself up, using the corner of the heavy oak desk to steady his trembling leg. He stood at attention once more, though his left knee quivered under his weight and sweat glistened across his forehead.

Obioma turned back to the basin floor. "Escort Okoye and his son to the cradles. Log three quarts each. Administer the restorative saline after the second pint so the hearts do not fail before the drainage cycle completes. Take the mother and the younger boy to the gate."

The guards moved instantly. Okoye did not fight them; he rose with the hollow, defeated compliance of a man who understood that the machinery of the state was larger than his grief. His wife gave no further cry, only pressing the younger boy's face into her skirts as the wardens guided her toward the outer archway.

On the porphyry platform, the two weavers were strapped into the angled bronze cradles. The lancets clicked into place with mechanical precision. Within moments, the dark, thick fluid was pulsing through the glass siphon tubes, draining down into the green-tiled runnels where the subsurface sluices carried it directly into the conduit sumps below.

Obiageli struck the small bronze gong again. "Case forty-three. Boma, carter of the North Canal."

A broad-shouldered man with mud caked to his shins was brought forward. He placed two cracked earthenware jugs of palm oil on the tray, his thumbs hooked nervously into his rope belt.

"The mules foundered in the ditch at Second Gate, Overseer," the carter rumbled, staring at the floor. "The grain was ruined by silt. I brought forty pounds of pressed oil. It burns clean in the parish lamps."

"We do not burn oil in the conduits, Boma," Obioma said, not even looking up from his tallies. "The dead do not march on palm grease. Did you bring coin?"

"Ten obols, Overseer. It is all the guild factor gave me for the salvaged hides."

"Ten obols buys five days of exemption for a single drayman," Obioma said. "You owe twenty for thirty days, plus the twenty-obol emergency surcharge. That leaves thirty obols in deficit."

"I have three carts under repair at the dry dock," the carter pleaded. "If I go into the cradle, who hauls the stone for the breach-gangs tomorrow?"

"The breach-gangs will haul their own stone," Obioma said. "Cradle one. Two quarts. If he faints before the second quart is drawn, douse him with vinegar and let him sit thirty minutes before resuming. Next."

The processing continued under the glare of resin torches. Case forty-four: a tanner with eighteen obols and two cured ox-hides; Obioma took the coin, seized the hides for the armorers, and took a pint from the apprentice.

At the wicket, a disturbance flared as the line neared its end. A gaunt girl with ash-stained forearms had placed twenty bronze obols upon the counter in neat stacks, arguing desperately with Clerk Obiageli over the doubled rate. Obioma did not waste time on an empty purse. He reached for the brass speaking horn resting on the cedar table, lifted it to his lips, and let his voice boom across the hall:

"Squad Fourteen! Conscript Chidalu, son of Nnamdi! Step to the cradle!"

Two iron-collared wardens seized the coughing boy and shoved him up the platform steps toward cradle three, his bare feet dragging against the wet flags while the girl was driven back behind the iron wicket by the halberdiers.

Case forty-six concluded the line: an elderly baker whose ovens had collapsed; Obioma remitted the woman because her veins were dry and calcified, but remanded her two nephews to the trench-labor battalions for thirty days of masonry haulage.

Obiageli tallied every ounce on his slate, his chalk grating in steady, rhythmic clicks against the stone.

"Weavers produce less blood than dry dates, but twice the noise," Obioma remarked dryly to the clerk as the baker's nephews were escorted down the hall. "At least the draymen bleed without reciting thirty stanzas of charter law."

Obiageli offered a faint smirk, dipping a rag into vinegar to wipe a smear of brine from his slate. "The draymen know the weight of a load, Overseer. The weavers only know the width of a hem."

As the line cleared, Obiageli set down his chalk and pushed his spectacles up into his gray hair.

"The night shift is concluded, Overseer," he said, his voice flat with fatigue. "Total collection across the four basins: forty-six hogsheads of fluid, sixty-two obols in bronze toll, four hundredweight of dry pulse. We are still five hogsheads short of the reserve required to charge the outer perimeter wards before dawn."

Obioma closed his eyes, letting the darkness behind his lids cool the burning ache in his skull. Five hogsheads. Nearly three hundred gallons. The deficit was growing every night, an insidious rot eating through the margins of their survival. If the Black Trench suffered another sustained assault before the next moon, the reserve cisterns would run dry, and the conduits would begin pulling ambient vapor, causing the dead to seize and rot on the parapets.

"The shortfall is concentrated in the Lower Kiln arches," Obioma said, opening his eyes and fixing them on the tally slate. "That district has four thousand souls registered on the parish rolls, yet their contribution has dropped thirty percent over the last three moons. They are hiding grain in the dry wells, and they are paying smugglers to move their sick and their young through the unmapped conduits beneath the foundations."

He reached for a sheet of heavy, vegetable-tanned hide that served as the garrison's formal sweep warrant. With a heavy reed pen dipped in thick iron-gall ink, he inscribed four concise lines:

To the Watch of the Eastern Span:

Commencing at fifth bell, execute a total cordon and search of the Lower Kiln arches from the Second Rib to the Potter's Sump. All unregistered stores of grain, pulse, and coin are subject to immediate confiscation. All persons evading the monthly blood-tithe are to be remanded directly to the drainage cradles.

He picked up the surveyor's seal, pressed it into the shallow dish of molten red wax, and stamped the bottom of the hide with the heavy, square mark of the Grave-Overseer.

He did not blow on the wax. He let it cool in the humid air, then picked up the warrant and held it out toward Warden Ekenna.

The young warden looked at the warrant. The dark ink glistened in the torchlight, black as coagulated blood against the pale hide.

"Overseer?" Ekenna asked, his voice barely louder than a whisper.

"You are from the Lower Kiln arches, are you not, Ekenna?" Obioma asked. The question was posed casually, but it carried the lethal weight of an iron drop-gate. "Your father was a cooper under the third arch. Your cousins still live along the clay-wash line."

Ekenna's jaw tightened. "Yes, Overseer."

"Good," Obioma said, thrusting the warrant into the young man's chest. "You know every cellar, every cistern, and every crawlspace between the aqueduct piers. You know which families keep their grain under the floorboards and which tavern keepers buy illicit sorghum from the ash-runners."

Ekenna's fingers closed around the stiff hide, his knuckles turning pale against the leather. "You want me to lead the sweep?"

"I am assigning you command of the third hound-line," Obioma said, leaning back into his chair and resting his heavy hands on the pommel of his cane. "You will take twenty wardens and four tracking hounds. You will start at the Second Rib and work your way down to the Potter's Sump. If you find so much as a peck of un-tithed grain or a single unregistered body hiding behind a dry-stone wall, you will bring it to the basin."

Ekenna did not look away, but the color had drained entirely from his face, leaving his skin the color of wet parchment. "And if the people resist the search?"

"Then you will remind them that the dead do not bargain," Obioma said. "And neither do I. If you return at dawn with empty carts and excuses about artisan charters, Ekenna, you will take your place on the porphyry platform alongside Master Okoye."

The overseer gestured toward the archway with a single flick of his fingers. "Dismissed."

Warden Ekenna snapped his heels together, gave a rigid salute that trembled at the elbow, and turned on his good heel. He limped rapidly across the wet flags of the tribunal floor, past the octagonal platform where the dark fluid was still draining through the green-tiled troughs, and vanished into the darkness of the barracks stair.

Obioma sat alone at the high desk for several minutes after the room emptied. Below, through the iron grates in the floor, the deep, mechanical hum of the conduit pylon continued to vibrate against his boots. It was slightly smoother now, the influx of fresh blood from the morning draft greasing the dry armatures of the dead on the parapets above, but the sour undertone remained.

The city was settling. He could feel it through the soles of his boots, through the iron shaft of his cane, through the crooked bone in his right knee. The stone was taking more shear than it was built to carry, and somewhere in the dark below the foundations, something was shifting.

Obioma picked up his iron cane, pushed himself up from the heavy chair, and started down the stairs toward the armory to inspect the hounds.
