Iron Under Steam

He threw his left steering lever into reverse and jammed the right forward, spinning his six-wheeled crawler in a tight, grinding half-circle until his rear exhaust nozzles were positioned barely twelve paces from the sinking stalker’s flank.

His movements were cold, disciplined, and practiced. He shoved the main draft damper wide open, letting the boiler pressure climb into the danger zone on the brass dial, then reached down and seized the emergency dump petcock—the heavy brass valve that vented the crawler’s entire lower cooling reservoir in a single burst.

The valve handle was scorching hot, glowing a faint, dull cherry against the darkness of the cab floor. Even through his steer-hide work gloves, the iron bit into his palms with sickening heat. István set his jaw, gripped the lever with both hands, and threw his entire body weight downward.

The valve slammed open.

Three hundred gallons of superheated, pressurized water and steam exploded from the crawler’s rear dump nozzles in a concussive roar.

The high-pressure blast slammed directly into the fragile basalt ledge supporting the stalker’s rear axle. The thermal shock was instantaneous. The sulfur-corroded rock, superheated on the surface and brittle beneath, fractured under the immense hydraulic pressure with the sound of a mine collapse.

The stalker’s rear axle dropped into the void. The heavy combat rig twisted sideways, its main boiler feed lines tearing apart under the torque. The ruptured pipes dumped tons of pressurized steam and boiling lignite slurry directly into the open mud cavity below.

A violent secondary explosion tore through the crater. A blinding wall of scalding white steam, pulverized lime, and boiling sulfur mud blasted upward, blotting out the morning sun.

István hauled the dump lever shut, but the concussive backlash was already upon him.

A geyser of boiling alkali brine and scalding steam ricocheted off the stalker’s armored flank, punching upward through the rusted gaps in the crawler’s floorboards.

The scalding wave tore across István’s left ribs and flank.

The agony was instantaneous and absolute—a searing white flame that drove every scrap of air from his lungs. The heat penetrated his heavy leather duster in a fraction of a second, melting the coarse wool lining of his inner tunic and fusing the scorched fibers directly to his raw skin. His left hand seized, his vision whitening into an expanse of blinding static as his heart hammered wildly against his ribs.

He bit his lower lip until blood ran into his mouth, refusing to scream. He forced his trembling right hand back onto the throttle lever, throwing the crawler forward onto the solid rock of the basalt spine before the collapsing ground could swallow his own wheels.

The crawler climbed onto the dark, hard stone of the ridge.

István slammed the brake dog into the drive gear, killed the engine draft, and slumped sideways across the iron bench. He lay there for a long minute, his breath coming in shallow, ragged hitches, each movement of his chest dragging broken glass across his left ribs.

The smell of his own scorched flesh filled the enclosed cab, heavy and sickening beneath the stench of sulfur.

With agonizing care, he used his right hand to undo the three brass buckles of his duster. Stripping the leather away from his torso took three minutes of excruciating effort; every inch of pulled cloth dragged away weeping strips of blistered skin. A patch the size of two open palms along his left ribs was burned red and raw, weeping clear fluid where the scalding brine had soaked through his tunic.

He reached for the crawler cab's auxiliary cold-feed valve, cracked the petcock with his thumb, and caught a cup of clear condensate in an old tin measure. He poured a small, steady trickle over the burn. The cold shock made his muscles spasm, but it rinsed the corrosive sulfur salts from the raw tissue. He took a single mouthful from the cup to moisten his tongue, swallowed the bitter drop, and dogged the valve shut.

He took his spare linen neck-cloth from his collar, folded it into a thick, dry compress, and laid it flat against the raw skin. Gritting his teeth, he cinched his wide leather sword-belt around his ribs, pulling the buckle tight until the pressure locked the compress in place. The compression was brutal, but it immobilized the torn muscle wall and stopped the bleeding.

He reached down, drew the Soltvadkert flensing knife from his boot, and kicked the cab door open.

The flats were deathly quiet.

The Syndicate stalker lay submerged to its roof deck in the bubbling sulfur cauldron, its iron plates groaning as the acidic mud ate into the hot metal. The crew was silent, buried in the overturned fighting compartment. Near the shattered rear hatch, which hung by a single sheared hinge, a man in an officer’s reinforced brigandine had dragged himself halfway onto the warped upper deck. Both of his legs were scalded and twisted beneath him, ruined by the steam blast.

The officer looked up through swollen, dust-caked eyes as István’s boots struck the basalt rock. He fumbled at his waist for a brass-mounted short sword, his fingers trembling and gray with shock.

István stepped forward and kicked the weapon from the man's grip. The blade spun through the air and vanished into the boiling mud with a sharp hiss.

"Where is Vica?" István asked. His voice was completely flat, drained of heat, panic, or malice.

The officer coughed, spitting a mixture of blood and yellow sulfur grit onto the deck plates. A dry, rattling chuckle escaped his throat. "You... you think you're clever, Kés. You think you bought that scholar his life."

István lowered the point of the flensing knife until the cold steel rested against the hollow of the man’s throat. "I asked a question."

"She isn't behind you," the officer rasped, his eyes widening with grim, spiteful satisfaction. "The Mistress knew... she knew Gábor couldn't clear the northern passes with an unregistered crawler on his ledger. You burned your boiler for a shadow, bodyguard."

István did not blink. "She took the bedrock canyon."

"Three heavy combat crawlers," the officer wheezed, his head dropping back against the iron deck plates. "She bypassed the thermal flats before the fourth hour of the night. She’s closing the gorge at Kőkapu right now. By midday... your scholar will be strapped to her command deck in chains, and Gábor’s teamsters will be hanging from their own wagon tongues."

István reached down with his gloved right hand and ripped the officer’s brigandine open.

Inside the inner pocket, he found an iron-bound enforcer kit: a heavy brass surveying compass sealed in tallow-soaked sheepskin, an iron tube containing a phosphorus signal flare with a percussion striker cap, and a threaded iron dispatch cylinder stamped with the triple-headed hydra of the Révész Syndicate.

István unscrewed the cylinder with one hand and shook out the parchment roll inside.

The script was written in dark, permanent walnut gall ink, signed with Vica Révész’s personal wax seal. The ink was barely six hours old. It was an operational intercept order detailing the split-pincer maneuver: a single secondary stalker was to pursue the high smoke over the thermal ridge to keep the runaway bodyguard occupied, while Vica led the primary hunting detachment—three eight-wheeled ironclads and twelve mounted lancers—straight through the dry northern canyon to establish an unbreakable blockade at the narrow gate of Kőkapu.

The trap had been laid while Gábor’s caravan was still hitching their teams in the dawn mists.

István stared at the parchment for two breaths. His decoy had worked, but it had worked too cleanly. By drawing the secondary stalker into the vents, he had isolated himself fifteen leagues to the southwest while Vica’s main force bore down on Gábor’s unprotected salt wagons.

Kőkapu was the only viable exit from the northern alkali basin. Gábor’s wagons, weighed down by three hundred bushels of coarse salt and towing three hundred gallons of commercial brine, could manage barely three miles an hour through the soft sand washes. They would reach the mouth of the Kőkapu gorge in less than four hours, completely unaware that three ironclad combat rigs were lying in wait between the high granite walls.

István rolled the dispatch tight, shoved it into his inner vest pocket, and dropped the brass compass into his duster alongside the phosphorus flare.

He looked down at the officer.

"Your Mistress is thorough," István said.

"She always is," the officer whispered, his head rolling to the side as his eyes fixed on the empty sky.

István did not linger. He turned on his heel, climbed the crawler's iron ladder, and pulled himself back into the cab.

The boiler was running dangerously low on water, the needle hovering at ten pounds per square inch, but the engine block was unbroken and the heavy six-wheel drive chains were intact. To reach Kőkapu before Vica sprang her ambush, he could not take the mapped trade tracks around the basin rim; he would have to force the damaged crawler across the unmapped, knife-edged granite spine of the upper escarpment—a vertical climb over loose basalt scree where a single broken axle or ruptured steam pipe would leave him stranded and dying in the high desert.

István pulled his goggles down over his eyes, gripped the scarred steering levers with his raw, blistered hands, and slammed the drive clutch forward.

The spoked wheels bit into the dark stone, throwing showers of black basalt sparks as the smoking crawler surged northeast into the jagged shadow of the cliffs.
