The eastern riverbank smelled of sulfur and dead fish.
Kaelen crouched in the freezing mud beneath a rotting dock. He kept his right leg perfectly straight, letting the wooden splints and hardened marrow-paste bear the agonizing weight of his fractured tibia. His breath plumed in the frigid air.
Across the black water, the Cinder Works dominated the skyline.
The quartz refinement factory was an industrial fortress of iron and brick. Massive exhaust pipes vented raw, sweltering heat into the winter sky. The sheer thermal output from the primary furnace clashed violently with the freezing void anchored behind Kaelen's sternum. The resulting biological confusion made his skin crawl with cold sweats.
Siora knelt beside him. Her tufted ears swiveled, tracking the mechanical rhythm of the Vanguard mercenary patrols marching along the opposite bank. She ignored the factory. She watched the fog rolling down the river.
A flat-bottom skiff materialized from the gray mist.
It bumped against the rotting pilings. Lyra Thorne stood at the bow. She wore a heavy oilskin coat over her silks, the high collar hiding her face. She dropped a heavy iron lockbox directly into the mud at Kaelen's boots.
Kaelen reached down with his raw right hand. He snapped the iron latch open.
He did not find a solid block of First Era obsidian.
Three jagged, fist-sized spikes of black volcanic glass lay resting on a bed of velvet.
Kaelen looked up. "I asked for a bunker-buster. I need massive density to crack an industrial furnace."
"I bought you scalpels," Lyra said. She stepped off the skiff, her boots sinking into the muck. "You do not break the furnace core. You target the intake valves. You disable the machinery."
"Vane's contract requires the Sterling infrastructure completely dismantled," Kaelen rasped. "A disabled valve gets repaired in a week. Vaporizing the core destroys the asset permanently."
Lyra looked at the towering factory across the water. "House Thorne intends to purchase that asset for pennies once Julian is disqualified. I will not let you turn my future real estate into a crater."
Kaelen picked up one of the heavy black spikes. The glass felt cold and absolute. "You changed the parameters while I am standing in the mud."
"I secured our mutual interests." Lyra pointed a manicured finger toward a row of towering concrete cylinders sitting directly adjacent to the factory's main processing floor. "Those are the eastern commercial silos. The three caravans of winter wheat I promised to the beast-kin are currently staged inside them, awaiting transit."
Siora went completely still.
The beast-kin warrior rose from her crouch. The wooden beads in her hair clicked together. She closed the distance to Lyra, her hardened claws extending.
"You placed my people's grain inside the blast radius," Siora hissed.
"I placed it where Kaelen's temper cannot ignore it," Lyra corrected, holding her ground. She radiated a wave of heavy, defensive heat from her collar. "If you detonate a massive kinetic shockwave to flatten that furnace, the resulting firestorm will incinerate the silos. The factory dies. But the Steppes starve."
Kaelen tightened his grip on the obsidian spike.
The political geometry locked into place. Lyra had manipulated the geography of the drop. She weaponized Siora's desperation against Kaelen's destructive momentum. He possessed the ammunition to level the Cinder Works, but pulling the trigger meant executing his only physical anchor in the lower city.
A steel-tipped quarrel punched through the wooden piling inches from Lyra's skull.
Wood splinters sprayed across Kaelen's coat.
"Drop the glass!" a harsh voice barked from the embankment above.
Kaelen shoved the iron box into Siora's hands. He threw his weight against the rotting piling, dragging his fused right leg out of the open mud.
Six Vanguard mercenaries fanned out across the top of the embankment. They wore heavy steel breastplates bearing the golden lion crest of House Sterling. They carried gear-cranked repeating crossbows. They had the high ground. They had the perimeter sealed.
"Sterling men," Lyra said. Her voice lost its arrogant cadence. "They shouldn't be patrolling this side of the river."
Kaelen looked at the mercenaries aiming down at them. "They aren't patrolling. They were waiting."
Patriarch Vane owned Kaelen's leash. Vane knew the target. The old man had leaked the coordinates of the drop to House Sterling. Vane wanted a bloodbath. He wanted Julian Sterling to find Lyra Thorne standing in the mud with a known terrorist, permanently burning the political bridge between the two families.
The lead mercenary leveled his crossbow at Lyra's chest. "The heir wants the Thorne bitch alive. Kill the slum rat and the animal."
Siora moved.
She did not draw an internal Thread. She grabbed the raw, ambient wind rolling off the freezing river. Funneling the pressure through her bare hands, she swept her arms upward. A concentrated gale slammed into the embankment.
The sheer atmospheric force ripped the mud and gravel out from under the mercenaries' boots. Two men lost their footing, tumbling down the steep slope into the freezing water.
The remaining four fired blindly.
Bolts shattered the wooden skiff. A quarrel grazed Kaelen's shoulder, tearing through the wool of his coat and biting a shallow groove into his skin.
Kaelen stepped out from behind the piling.
He possessed three obsidian spikes. He needed all of them to surgically disable the factory valves without burning the grain.
He abandoned the math. Survival demanded the cost.
He aimed his empty left hand toward the massive exhaust pipes of the Cinder Works across the river. The air tasted of burning coal. He dragged a thick, violent Ignis Thread across the water. He bypassed his empty chest and shoved the raw thermal energy directly into the black spike resting in his right palm.
The obsidian drank the heat.
The glass did not warm. It did not fracture. The physical mass simply increased, doubling in weight in a fraction of a second as it absorbed an industrial volume of fire.
Kaelen lunged forward. His right boot hit the mud. The marrow-paste inside his fractured tibia screamed in protest, but the splints held the bone aligned. He drove his arm upward and slammed the primed obsidian directly into the stone retaining wall supporting the embankment.
He released the containment boundary.
The stored thermal energy violently decompressed.
White fire erupted from the stone. The concussive blast bypassed the open air, shearing straight into the earth. The retaining wall shattered into thousands of jagged shrapnel fragments. The massive thermal expansion flash-boiled the mud.
The explosion tore the top of the embankment away.
The four Vanguard mercenaries vanished inside a roaring cloud of pulverized rock and expanding steam. Screams cut off abruptly as the concussive wave pulverized their steel breastplates.
The backlash hit Kaelen.
The shockwave threw him backward. He crashed into the freezing river water, his spine slamming against the submerged hull of the skiff. The impact forced the oxygen from his lungs. Ringing deafness completely replaced the roar of the river.
He choked on the brackish water, thrashing his good arm to pull his head above the surface.
Siora hauled him up by his collar. She dragged him onto the muddy bank.
Kaelen spat foul water onto the dirt. He pushed himself onto his hands and knees. His right leg throbbed with a sickening, relentless heat. His left shoulder bled freely.
He looked at the embankment.
A massive, smoking crater replaced the retaining wall. Charred pieces of steel armor littered the boiling mud. The ambush was dead.
Across the river, the Cinder Works reacted.
Heavy brass klaxons began to wail. The deep, mechanical shrieks echoed across the water, cutting through the ringing in Kaelen's ears. High-powered magical searchlights flared to life along the factory's perimeter walls, sweeping the riverbank in frantic, intersecting arcs.
The Vanguard garrison was fully mobilized. The fortress was awake.
Lyra climbed out of the mud. She brushed a layer of wet ash from her ruined silks. She looked at the smoking crater, then at the blazing searchlights across the water.
"They know we are here," Lyra stated.
Siora clutched the iron lockbox against her chest. "We lost the element of surprise. You lost a third of your payload."
Kaelen dragged himself to his feet. He leaned his weight heavily against the surviving wooden piling. The cold void inside his ribs expanded, feeding on the damp chill of his soaked clothes.
He looked at the two remaining obsidian spikes in the iron box. He looked at the concrete grain silos sitting adjacent to the heavily armed factory. He was bleeding, his ammunition was depleted, and he was walking into a fortified meat grinder.
He reached into the box and pulled out the remaining glass.
"We go loud," Kaelen said.
