The Distribution

The air in the breached sluice tasted of pulverized lime, bitter sulfur, and the cold salt brine pooling around Praxos's boots.

He crouched beneath the overhanging lip of the western footing, pressing one callused hand against his bruised ribs to still the sharp throb with every breath. Above him, four feet of oak joists and fractured travertine decking hung in jagged teeth, held together only by the secondary cedar braces he had deliberately spared from the blast. Through the twelve-foot crater in the arena floor, dusty daylight cut a wide gray diagonal into the black water of the drain.

A shadow crossed the shaft of light. A scarred, oil-darkened arm reached down through the splintered timber, fingers hooked into an iron hoist ring.

"Up," Xantheos said. His voice came through the dust, flat and clipped, carrying the shallow rasp of sixty paces of defensive footwork. "Before the wardens stop arguing about the sand."

Praxos reached up and locked his wrist around the duelist’s forearm. The pull was brutal and direct. Xantheos planted his heels against the broken oak sill, hauling Praxos clear of the sub-sluice with a single heave that tore a sharp gasp from Praxos’s throat as his cracked ribs scraped the wood. Praxos rolled onto the fighting sand, spitting gray grit, and pulled his legs beneath him.

Around them, the Sunless Atrium was a cauldron of shouting. In the center of the ring, fifty paces away, the heavy champion of House Karystos lay pinned beneath his bronze pavise and three tons of collapsed decking, thrashing in the sand while two chirurgeons in blood-soaked leather aprons wedged iron pry-bars under the bronze rim to keep him from suffocating. The herald of the Sand stood upon the referee’s raised stone dais, blowing three uneven, brassy blasts from his long trumpet to ratify the bout’s conclusion.

"Winner by immobility," the herald bellowed into the gallery, his voice cracking against the limestone vaults. "House Archon retains the Western Canal."

Across the tiered stands, hundreds of patricians and factor clerks were already scrambling over the stone benches, shouting in fury or terror as white dust drifted across the lower balustrades. High above the panic, the shadow of Archon Mythias remained motionless at the marble rail, his gaze still anchored to the sheared pillar in the pit.

"Get on your feet," Xantheos said, catching Praxos by the strap of his leather tool harness and hauling him toward the southern service sally-port before the household wardens could form a perimeter. "If Lady Oenone filed those vouchers in time, we have about four minutes before Mythias calls out the iron guard."

They ducked beneath the low travertine archway just as a runner in the faded gold-and-green silk of Oenone’s household rounded the turn. The boy was slick with sweat, clutching a bronze dispatch cylinder stamped with the still-wet wax of the Western Canal tribunal.

"The registry accepted the claim," the runner wheezed, shoving a duplicate slip into Xantheos's hand. "Lady Oenone filed the cargo manifests under the emergency heating ordinance before the herald blew his third blast. The five marrow cylinders are already loaded onto the water-carts at the canal gate."

Xantheos glanced down at the parchment slip, his thumb tracing the embossed release seal of the High Council. For three heartbeats, his face showed nothing—no triumph, no relief, only the cold stillness of a man who had counted every step to this edge for seven years.

"Move," Xantheos said, pocketing the voucher into his leather cuirass. "The carts have an eight-minute lead on the purge squads."

They reached the Lower Cistern basin forty minutes past noon, following the subterranean spillways to bypass the street gates and the fortified iron turnstiles.

The smell of the lower wards reached Praxos before they climbed through the inspection shaft: the dry, metallic reek of Petrifying Ash hanging thick in the stagnant air. In the lower basin, pressed against the massive, windowless masonry of the city's outer wall, the ash fell in steady, chalky flurries that never melted.

Hundreds of refugees and weavers huddled in the narrow alleys surrounding the central square, wrapping their limbs in ragged burlap to slow the gray crust forming on their skin. Beneath a sagging canvas awning, Master Timon sat beside his silent loom, his rough hands gently rubbing the stiffened, slate-colored calves of his youngest daughter. Near the stone cistern mouth, fourteen-year-old Kaelon stood guard with a rusted pry-bar, his thin face pale under a heavy dusting of white soot.

When the two heavy handcarts clattered into the cobblestone square under the escort of four hired warehouse porters, Kaelon dropped his iron bar with a ringing clang that echoed off the damp brickwork.

"Master Praxos!" Kaelon lunged forward, catching Praxos by the elbow as the mason stumbled over an uneven paving stone. "They said the Atrium fell. A runner from the third ward said the purge commander burned the workshop down to the bedrock."

"The workshop gave way," Praxos said softly, his voice raspy from stone dust. He patted the boy’s shoulder with a bruised palm. "The timber was dry anyway."

Xantheos helped the porters haul the first wooden crate from the cart bed, wrenching the pine lid free with a crowbar. Inside, nestled in thick river silt, lay the five heavy glass cylinders, their cobalt marrow glowing with a deep, pulsating radiance that turned the surrounding gray mist into liquid violet.

"You brought the whole court reserve," Timon whispered, limping forward from his shanty, his eyes wide as he stared at the mineral glow. "If Mythias catches this in the lower ward, he will hang every weaver from the gatehouse."

"He will try to hang us regardless," Xantheos said, resting the pommel of his short sword against the cart wheel. "Next time you want to settle a tax dispute, Stone-breaker, bribe a clerk instead of bringing down three hundred tons of public travertine."

"Clerks take the money and ask for more next winter," Praxos murmured, kneeling beside the district’s central heating flue. "Stone stays where you drop it."

He ran his fingers along the rim of the ancient iron hearth-manifold set into the center of the square. The intake grating was choked with gray ash and calcified slag, suffocating the draught. If they poured the marrow directly onto the cold iron, the thermal shock would crack the clay conduits running beneath the shanties, venting lethal mineral vapor instead of heat.

Praxos pulled two chisels and a small brass hand-trowel from his belt. "Kaelon, bring me three buckets of dry silica sand from the mortar bins. Timon, clear the flue exhaust vents along the western wall."

Working with measured precision despite the stabbing ache in his side, Praxos cleared the slag from the three primary intake ports. He spread four inches of coarse river sand across the iron grate to buffer the ignition plate, then uncapped the first glass cylinder. The thick, luminous Pyrophos marrow poured out like glowing honey, soaking into the sand bed without spilling a single drop into the drainage channels.

He struck his iron striker against a piece of dark chert.

A tiny yellow spark caught the marrow's edge. A low, resonant hum vibrated through the flagstones beneath their boots as the blue flame blossomed, roaring to life with an intense, steady heat that swept the chill from the square in five heartbeats.

Praxos adjusted the brass draught-flaps, guiding the radiant heat deep into the subterranean clay pipes. Across the cobblestones, the chalky frost on the stones turned to dark water. Children pushed back their burlap hoods, holding their stiffened, ash-crusted fingers over the warm vents as the gray petrification scales softened and fell away like dried mud.

A collective sigh moved through the crowd, a sound of breath returning to people who had forgotten what warmth felt like.

Timon sank onto an overturned tub, burying his face in his callused hands. Kaelon stood by the manifold, his young face bathed in the blue glow, grinning through his tears.

Praxos leaned back against the iron rim of the cart, letting the heat seep into his bruised ribs. For the first time in two days, the cold weight in his chest eased. The mineral was in the hearths. The children were warm.

Then, from the high ridges of the inner city, the first horn sounded.

It was not the high, clear trumpet of the duelist courts, nor the rhythmic bell of the curfew wardens. It was a massive, discordant blast of hammered bronze—a deep, shuddering roar that rattled the tiles on the shanty roofs and sent flocks of ash-gulls screeching into the gray sky.

A second horn answered from the South Gate, followed immediately by the third from the Archon’s Citadel.

The three blasts of the Iron Siege.

Xantheos snatched his sword from the cart wheel, his knuckles whitening as he looked up toward the high aqueduct bridges.

"That is not a purge squad," Xantheos said, his voice dropping into the cold cadence of the fighting pits. "Mythias has suspended the charter. He has declared the lower basin an enemy camp."

Praxos stood slowly, turning his eyes toward the upper tiers where iron-clad cohorts were already forming behind the parapets, their long pikes catching the dim daylight.
