Fire in the Gullet

Hayes tore the leather gauntlet from his right hand and threw it aside. Thick leather would catch on the hound's throat scales and slow him down; bare skin gave him the precision he needed, regardless of the heat. He shoved his bare right arm into the tub of mutton tallow, coating his skin from fingertips to elbow in thick grease to create a temporary barrier against the acid wash. He drew one deep lungful of cold air, planted his knees against the road, and drove his arm straight down the beast's open maw.

The heat inside the throat was staggering. His knuckles scraped against the hard, backward-facing scale ridges that lined the hound's gullet. The powerful swallowing muscles contracted around his forearm like wet hemp ropes, squeezing with enough force to bruise the bone.

His fingers reached the obstruction. The slag-ball was a jagged, blisteringly hot mass of fused copper, flint, and hardened chemical resin, jammed tight against the fleshy ring of the crop entrance. The caustic fluid pooled around the blockage bit through the tallow barrier, searing into the small cuts on his knuckles with the agony of glowing coals.

Brisket gagged, a desperate, reflexive spasm that shook the hound's entire frame and nearly drove the iron pry-bar through the roof of his mouth.

Hayes did not pull back. He wedged his index and middle fingers beneath the lower edge of the slag-ball, bracing his thumb against the creature's throat cartilage. He twisted his wrist with a sharp, brutal jerk, levering the jagged lump free from the swollen tissue.

With a wet, tearing sound, the obstruction came loose. Hayes dragged his arm back out of the maw, dragging the blackened mass with him and hurling it across the limestone roadbed, where it landed with a dull metallic clatter.

Without pausing to catch his breath, Hayes grabbed the dense ball of lime-tallow paste from the tin basin. He drove his hand back into the hound's mouth, shoving the alkaline mass past the base of the tongue and forcing it down the open passage into the lower furnace gut.

"Bar clear!" Hayes shouted.

He ripped the iron pry-bar out. Brisket’s jaws snapped shut with a crack that echoed off the nearby stone bluffs. Hayes clamped both hands over the hound’s snout, holding the jaws firmly closed while using his forearms to massage the creature’s thick throat in long, downward strokes.

"Take it down, boy," Hayes urged, his chest heaving. "Swallow the lime. Put the fire out."

For five long heartbeats, the only sound was the cold wind scraping through the dry brush of the Barren Reach. The hound lay motionless on the stone, his eyes rolled back, his flanks frozen in rigid paralysis.

Then, deep within the creature’s belly, a muffled hiss sounded, like water dropped onto red-hot iron. The alkaline lime struck the pool of boiling vitriol.

Brisket’s midsection heaved violently. The hound rolled away from Fiona’s grip, scrambling onto all four splayed paws with a frantic scramble of claws. He lowered his broad, armored snout toward the ditch and purged.

A thick stream of gray, neutralized sludge poured from his throat, splashing across the roadbed in a steaming, chalky puddle. The noxious blue-green fumes were gone, replaced by the heavy, harmless smell of extinguished lime, wet bone meal, and rendered mutton fat.

The hound stood trembling in the darkness, drawing deep, ragged breaths of cold night air. His flared dorsal plates gradually lowered, settling flush against his thick hide with a sequence of dull metallic clicks. He shook his massive head from side to side, scattering flecks of white paste across the dirt, then turned and pressed his damp snout firmly against Hayes’s bruised ribs.

Hayes leaned his forehead against the beast’s warm neck plates, letting out a long, shuddering breath. His right arm was red, blistered, and smeared with chalky residue, but the steady, rhythmic rise and fall of the hound's chest told him the furnace had stabilized.

"Good beast," Hayes murmured, scratching the rough, armored skin behind Brisket's ear flap. "Good hound."

Fiona straightened up slowly, rubbing her bruised forearms before shaking out the hem of her travel-stained skirt. She looked down at the dark stains on her boots, then glanced at the steaming pool of vomit in the ditch, her expression tightening with dry disgust.

"If that beast of yours ever ruins another pair of my riding boots, Carver," Fiona said, her tone level and razor-dry, "I am deducting the full merchant price from your copper salvage bonus. And you will spend tomorrow evening boiling the fat out of my cloak."

"You won't have to worry about the boots if we take this convoy into the canyon," Hayes said, reaching for his belt and drawing his short skinning blade.

Fiona paused, her eyes sharpening in the yellow glow of the storm lantern. "What are you talking about?"

Hayes knelt in the roadbed beside the blackened slag-ball he had pulled from Brisket's throat. The mass had cooled against the night air, hardening into a porous, dark gray cinder roughly the size of a fist. He set the flat of his blade against the crust and struck the pommel with the heel of his hand, cracking the shell into several jagged fragments.

Inside the core, tiny flecks of pale stone caught the lantern flame, glittering like crushed glass among the fused copper turnings. Hayes carved out the dense, unburnt center—a solid, thumb-sized cake of hardened chemical catalyst—and wrapped it in a square of lead foil from his veterinary kit before tucking it securely into his belt pouch. He scraped a pinch of the remaining gray powder onto the flat of his blade, held it up to the light, and rubbed a grain between his calloused fingers.

"Look at this grit," Hayes said, extending the blade toward her.

Fiona bent closer, squinting at the powder. "Crushed quartz? Or river flint from the wash?"

"Neither," Hayes said, his voice dropping into a hard, quiet register. "It’s diamond paste. The kind used in high-pressure core-drills by deep-vein miners and military engineers. And the chemical base isn't simple road acid. It's refined vitriol spiked with antimony salts. That mixture doesn't occur naturally anywhere between here and the coast."

Fiona’s eyes narrowed. "Polk? Did that frontier captain salt the roadbed after we broke his gate?"

"Polk doesn't have the brains to mix antimony, and he certainly doesn't have the coin to burn through diamond-tipped drill bits," Hayes said, shaking his head. "This wasn't done from the garrison. Someone set up on this highway with a portable drilling rig, bored straight into the foundation stone to sever the resonance lines, and poured concentrated solvent down the boreholes to dissolve the bedrock."

He pointed the tip of his knife toward the north, where the black cleft of Devil's Throat rose against the star-filled sky like a broken tooth.

"Brisket picked up this grit three miles south," Hayes continued, looking up into Fiona's face. "The saboteurs didn't just break the stone behind us to trap us in the dead reach. They worked their way north ahead of us. They dumped their core tailings and solvent wash along the road shoulders as they moved."

Fiona looked up from the knife blade, her gaze traveling along the dark, silent trail toward the canyon mouth. The narrow gorge pinched the highway between sheer sandstone bluffs that rose over eighty feet on either side.

"They aren't just blinding the road," Fiona said slowly, the tactical reality settling into place. "They are clearing the highway to control the corridor."

"Worse than that," Hayes said, standing up and sliding his knife back into its sheath. "Antimony and vitriol aren't just for dissolving stone slowly. When you pack them into dry boreholes alongside sulfur and drop a spark into the mix, they fracture sandstone like rotten timber. If they drilled the canyon walls at Devil's Throat the same way they drilled the roadbed, they don't need an army to stop this convoy. They just need one linen match to bring forty tons of rock down on top of our wagons."

Fiona stood in silence for several seconds, watching the distant, black rim of the canyon. Behind them, down the long line of freight wagons, the horses stamped nervously in the dark, sensing the dead quiet of the surrounding wasteland.

"We have forty tons of raw iron, timber, and copper sitting on these axles," Fiona said, her voice clipped and decisive. "If we turn around, Polk will demand double toll to let us back through the gate, and we lose three weeks of transit. If we push forward into that bottleneck, we might be driving straight under a deadfall."

Hayes walked back to the rear of his wagon, checking the manganese links that secured Brisket to the drag-axle. The hound was up on all four legs now, his tail swaying in a slow, watchful rhythm as he scent-tested the north wind.

"We don't crawl back to Polk's gate," Hayes said. "And we don't roll forty tons of freight into a blind trap. Go down the line. Tell the teamsters to douse every lantern and lash down the trace chains so they don't rattle. Give them crossbows and javelins."

Fiona nodded once, her pragmatic composure fully restored. "And what are you doing?"

Hayes rested his blistered hand on Brisket’s armored shoulder, feeling the deep, steady hum of the beast's restored furnace.

"I'm taking Brisket up the western bluff on foot before the wagons move," Hayes said. "We're going to find out who is holding the fuses before we roll another wheel into that throat."
