Steppe Hammers

Captain Terhenen did not give a speech in the lower kraal before the breach. In the hour before they struck the lower barricades, his four hundred hungry steppe auxiliaries sat along the basalt benches, sharpening leaf-bladed bronze short swords on river pebbles and binding split bull-hide sandals with boiled ox-sinew. The dry wind whipping down the canyon carried the greasy stink of the Great Crucible blast furnaces, thick with bitter emerald arsenic that bit the tongue like sour vinegar.

Captain Terhenen walked the central row of timber stalls, his heavy iron-headed sledge slung across his shoulder by a greasy hemp strap. At his hip hung the six-pound double-ox war-bronze ingot taken from the flue-diver an hour before, its cool weight bumping against his thigh.

Sledge-Leader Tuurelt crouched over an overturned cask, carving thin strips from a gray slab of cured mule flank with a broad skinning knife. He flicked a ribbon of fat onto the blade of his copper-shod timber maul and offered it to Terhenen.

"Mule collar," Tuurelt muttered, his scarred jaw working around a gristle knot. "Tastes like dry boot soles and three seasons of dust. Better than the council's poisoned barley mash, though. The mule had the decency to die before the clerks weighed its lungs."

"The mule did not die of a ledger debt," Terhenen said, taking the strip and chewing the salty sinew. "Eat your share and pass the cask down the ranks. Three mouthfuls per man. No fires in the pens."

"The boys are chewing their scabbards," Tuurelt said, nodding toward the rows of gaunt veterans. "They watched Joukalt's pikes sweep the causeway. If the Copper Guard locks the bridge gatehouses, we eat leather until we rot."

"Joukalt has sixty pikes at the gatehouse and two hundred hungry haulers at his back," Terhenen said. "He watches the road because he thinks an army needs stone beneath its boots. We are not taking the road."

He jerked his chin toward the stone trough at the far end of the kraal.

Vappuinen knelt beside the trough under the spears of two steppe archers. The thirty-pound copper shim remained lashed to the boy's spine, the bull-hide ropes biting deep into his ragged tunic. His greased goggles hung around his neck, and his charcoal-lime breathing cowl was crusted yellow with dried sulfur.

Terhenen walked over. "Stand up, flue-diver."

Vappuinen pushed his palms against the slimy basalt curb, knees trembling as the copper ballast dragged his shoulders down. "The third inspection shaft is two hundred paces down the dry conduit," the boy rasped, his voice raw from furnace smoke. "The descent drops eighty feet through the drainage flue. You cannot drag sledges down a vertical chute."

"We do not use the vertical chute," Terhenen said. He tapped the flat ox-mark of his captured ingot against the boy's copper ballast. The metal rang clear against the stones. "The old city records call it the King's Spillway. A lateral carriage ramp built two hundred winters back to haul quarry slag to the riverbed. The foundry matriarchs walled the upper portal with dry basalt blocks when the lower works flooded, but the arch beneath Pier Five still breathes."

Vappuinen stiffened. "The fifth pier sits directly beneath the Great Crucible's suspension cradles. If the quench valves on the high vats dump while you are under the arch, sixty thousand gallons of boiling arsenic slurry wash down the ramp. You cook before you reach the winches."

"Then you will pray the furnace tenders are as lazy as their overseers," Terhenen said.

He stepped back and whistled twice between his teeth, a shrill plains signal.

Across the kraal, four hundred men stood. The foreign auxiliaries wore boiled bull-hide and quilted salt-steppe wool instead of clattering bronze plates. Six haul teams took hold of the heavy hemp drag-lines hitched to six heavy timber sledges.

The first four sledges carried the forty cold-hammered copper counterweights—ten rectangular blocks per sledge, each ingot stamped with the citadel's broad arrow and weighing four hundred pounds. Eight tons of dense, reddish metal looted from the Lower Canyon Armory before Joukalt's patrols could seal the vault. The two rear sledges held crates of thirty-pound balancing shims, iron snatch-blocks, and coils of greased bull-hide rope.

"Ropes on shoulders," Terhenen ordered. "Muzzle your coughs. If a sledge groans on a turn, chank the skids with sheep tallow."

Tuurelt took the lead sledge team, bent against the harness. Two skirmishers hauled Vappuinen up by his collar, shoving the weighted boy to the head of the column beside Terhenen.

They surged through the breached timber barrier of the lower causeway, scattering the citadel pickets in a flurry of overturned braziers and splintered bucklers. While the alarm gongs wailed above, Terhenen did not charge the causeway stairs. Guided by Vappuinen's staggering figure, the six sledges were hauled along the narrow basalt service lip directly beneath the bridge's foundation arches, slipping out of the sight of the West Curtain parapets and plunging into the shadows behind a collapsed grain storehouse.

There, half-buried under furnace clinker, lay the mouth of the spillway. The smell hit them at once—stagnant mineral water, rot, and the dry, metallic sting of sublimated arsenic crusting the masonry.

"Down," Terhenen said.

They entered the basalt culvert. The passage was ten paces broad, its floor paved with basalt flags cut with transverse grooves to brake rolling sledges. As the column moved into the mountain's root, the city rumble faded, replaced by the rhythmic thump of foundry pumps vibrating through solid rock.

Three hundred paces in, the conduit split into three low arches.

Vappuinen pointed toward the left tunnel. "The left branch leads around the secondary slag flue. The center is blocked by deadfall."

Terhenen halted the file. He unhooked a grease-lamp from his belt, shielding the wick flame with a calloused palm, and held it before the openings.

The flame bent toward the left arch, guttering in a warm draft that smelled of sweet almonds and boiled cabbage. In the right arch, the flame stood still. In the central arch, the flame leaned toward them, flickering in a steady, cold downdraft that tasted of river silt and wet lime.

Terhenen drove the iron head of his sledge into the flags beneath Vappuinen's boots. The stone cracked.

"Sweet almond is green arsenic vapor from a leaking quench manifold," Terhenen said, leaning close to the boy's cowl. "The draft would have suffocated fifty men before the second sledge cleared the arch. You take the center."

Vappuinen swallowed, his throat clicking inside his leather filter. "The center climbs directly into the foundation piers. The stone is thin."

"Thin enough to hear the foundries above," Terhenen said. "Walk."

The column hauled the sledges up the central incline. The gradient steepened sharply. The auxiliaries dug the toes of their bull-hide boots into the basalt ribs, their breathing turning ragged inside charcoal cloths. Whenever a sledge threatened to slide backward, Tuurelt and four shock-troopers drove bronze wedges beneath the ash-wood runners, bracing the dead weight while the pull-teams caught their wind.

Sweat cut clean gray tracks through the soot on Terhenen's neck. He kept his shoulder to the second sledge, his calves burning as eight tons of stolen copper crawled through the dark belly of the fortress.

After an hour of climbing, the conduit opened into an immense vaulted cavern.

Basalt pillars, each twelve paces thick, rose out of the damp floor like subterranean tree trunks, disappearing into the vaulted ceiling forty paces above. Through iron-grated ventilation wells in the high vaulting, green flashes of furnace fire illuminated the dripping stone, followed by the tectonic boom of the Great Crucible's bellows.

Directly overhead hung the cyclopean foundation blocks of Pier Five, the western anchor of the High Basalt Bridge. Suspended from the masonry ceiling by bronze brackets were four massive counterweight cradles, their empty iron baskets waiting for the ballast that balanced the bastion's soaring ram-gates.

Terhenen walked the perimeter of the pier, his fingers trailing over the wet stone.

"Here," he whispered.

Tuurelt brought the six sledges to a halt beneath the central hoist well. The steppe warriors unslung their tools, their movements disciplined and soundless. Heavy timber sheer-legs were raised against the basalt pillar, and iron snatch-blocks were lashed to the overhead cradle beams with oiled bull-hide cables.

Vappuinen slumped against a foundation footing, his chest heaving under the thirty-pound copper shim, watching the mercenaries rig the copper counterweights beneath the Great Crucible's suspension anchors.

Terhenen knelt beside the lead sledge and drove two bronze locking pins into the timber chassis, anchoring the heavy winches to the bedrock. He looked up at the stone ceiling, where the faint shimmer of emerald light outlined the bronze armature of the high fortress. The iron gates of the Great Crucible were twenty yards above their heads, locked against a starving world. Beyond them lay the arsenic vaults that could purchase food, wagons, and forty leagues of open northern steppe.

He laid his hand against the cold, smooth face of the four-hundred-pound copper block, the desire for the open plains hardening like hammered iron behind his ribs.

"Rig the trip-lines to the windlass," Terhenen told Tuurelt. "When the third night-bell rings, we take the sky from them."
