The rusted iron hatch leading down into the sub-basement of the town boiler annex gave a familiar, groaning shriek as Arthur pushed it open with his shoulder.
Inside, the underground air was warm and heavy with the scent of simmering bone marrow, wild sulfur-cabbage, and wood smoke. A cast-iron fire bowl salvaged from the fire chimney pipes glowed red in the center of the flat stone slab floor. It cast dancing amber shadows across the damp brick walls.
Toby Mallow was crouched by the hearth, a wooden stirring paddle clutched in his blistered right hand, an oilcloth ledger balanced precariously across his knees. He wore a giant woolen sweater with frayed elbows, a brass jeweler’s magnifying glass pushed up into his mop of ginger curls.
At the sound of the iron door latching shut, Toby leaped to his feet so wildly that three stubby animal fat candles rolled off the edge of his workbench.
“Arthur!” Toby shouted, his voice cracking with panic before dropping to an urgent, conspiratorial whisper. “Did they take your badges? Did the court guards impound Grimm? I heard the sirens forty minutes ago! The dock workers said Gregory Vance marched into the transit hall with six armed guards and an anti-riot cannon—”
“Gregory Vance is currently in a transport van bound for dangerous aether-mining battalion seven in Sector Nine,” Arthur said calmly, kicking his muddy boots against the doorframe to dislodge the street sludge.
Toby froze, the wooden paddle hovering six inches above the steaming soup pot. His jaw dropped, his pale blue eyes blinking in total confusion behind his fogged glasses.
“He’s... What?” Toby whispered.
Arthur unclipped the heavy bronze medallion from his belt and tossed it through the air. Toby caught it by reflex, his fingers curling around the cold, heavy metal. He pulled down his jeweler’s magnifying glass, angling the lens toward the candlelight.
“Bronze Vanguard Cadet insignia,” Toby read. His voice shook as his eyes traced the crisp military stamps. “Registration number 904-Omega... Authorized by the Provost Marshal Trial... With full military bursary pay...” He looked up, his chest heaving. “Arthur, this is an official commission! They didn’t just clear you—they inducted you!”
“There’s more,” Arthur said. He set the rolled thick parchment scroll on the corner of the drafting table. “Independent Tier-Three Sanctuary Charter. We have lawful ownership of this boiler annex, the lower drainage sub-level. The rear loading dock. Full exemption from town leasing fees and clan tithes for five years.”
Toby stared at the wax seal of the Central Military Governor as if it were a piece of raw radioactive plutonium.
Then, with a strangled yelp that sounded like an asthmatic tea kettle reaching boil, the teenage supply boss threw his arms around Arthur’s neck, nearly knocking both of them into the water barrel.
“We have a deed!” Toby cried, tears cutting pale, clean tracks through the fire soot on his cheeks. “An actual legal deed! The land court guards can’t kick us out! Mrs. Gable can’t threaten to burn our blankets! We’re not squatters anymore, Arthur! We’re a registered safe hall!”
Grimm padded softly across the flat stone slabs, sniffing the hem of Toby’s woolen trousers. The hound gave a short, muffled huff, nudging Toby’s hip with the flat of his snout until Toby stumbled backward onto the low wooden stool.
“Hey, easy, big guy,” Toby laughed. He wiped his eyes with the cuff of his sweater before scratching Grimm vigorously behind both ears. “Look at you. You broke House Vance’s pet dragon and ruined their chief guard in three seconds flat. The dock boys are already calling you the Black Bone Demon of Ward Nine.”
Grimm gave a low, rumbling groan of total bliss at the ear rub, his hind leg drumming rhythmically against the stone floor. When his wagging tail accidentally clipped an empty tin mug. It sent it clattering across the hearth, the hound right away froze. His ears flattened backward, his head dropped between his forepaws, and he slunk into the far corner of the room. That turned his face to the brick wall in deep, deadpan shame.
“He’s still doing the invisible corner-shame,” Toby observed, grinning as he picked up the tin mug and set it back on the table. “Arthur, he’s a three-hundred-pound ancient war beast who crushed a silver-steel-plated dragon. Why does he act like an embarrassed street puppy when he knocks over a cup?”
“Because his automatic nervous system is mammalian,” Arthur replied. He pulled off his stained canvas work-coat and hanging it from an iron hook beside the chimney pipe. “His hungry instincts are ancient. But his emotional conditioning is that of a stray hound who lived four months on alley scraps. You don’t erase canine ethology just because you wake up fifteen percent of an ascendant gene.”
Arthur walked over to the corner, knelt beside Grimm, and tapped the hound’s flank twice.
“Corner time is over, Grimm,” Arthur said gently. “Come eat.”
Grimm looked over his shoulder with one cautious amber eye. Seeing no reprimand in Arthur’s stance, the hound rose smoothly, shook his pelt with a soft rattle of his ribs. Then he padded over to the wooden trencher beside the hearth.
Toby ladled out three massive wooden bowls of the marrow stew. The broth was thick and amber-tinted, fragrant with wild mountain thyme, roasted sulfur-roots, and rich jelly-like animal fat pulled out from crushed bovine femurs. Arthur took his seat on a pine packing crate, sipping the boiling broth from a clay pot bowl.
The heat spread through his chest like a warm balm, easing the dull, throbbing ache behind his temples.
In his last life as an orthopedic trauma surgeon in the mountains of Yunnan, late-night emergency surgeries were always followed by bowls of scalding noodle broth in the quiet hospital staff room. The physical tiredness, the metal smell of dried blood on his knuckles, the quiet hiss of boiling water. The body sensations were matching across ten thousand light-years and two different lifetimes. He had lost his world, his clinic, and his razor-sharp theater. But the duty of the blade remained unchanged: to preserve life, repair the broken, and excise corruption.
Around midnight, the heat inside the boiler room began to rise unnaturally.
Grimm, who had curled up on his side beside Arthur’s cot, let out a sharp, shuddering whine.
Arthur set down his medical notes instantly, moving to the hound’s side in a single fluid motion. He placed his bare palm against Grimm’s flank.
The hound’s skin was burning. A deep, under-skin heat was streaming from his long bones, registering at nearly forty-one degrees. Beneath the dark skin, the thigh shafts and lower-back bones were shaking at a high, sub-heard hum.
“Arthur?” Toby called out from his cot, sitting up in alarm. “Is he sick? Did Gregory’s shock-baton leave a leftover charge in his marrow?”
“No,” Arthur said calmly, his fingers palpating the hound’s stifle joint and running down the metatarsals. “The closed reduction of his shattered jaw and the sulfur-zinc cryo-spark we injected last night triggered a backup epigenetic cascade. The latent Fenrir lineage is consolidating. His osteoblasts are rebuilding the outer-brain bone at ten times the standard cellular speed.”
Arthur retrieved two clean linen towels. It soaked them in the cold water tank water, and laid them across Grimm’s skull and neck spine.
“Breathe, Grimm,” Arthur murmured, keeping his voice steady and low. “Steady and slow. Let the bone knit.”
Grimm leaned his muzzle hard against Arthur’s thigh, his teeth clicking together as a rhythmic wave of tremors rippled through his hindquarters.
Beneath the wet towels, the transformation was purely living. There was no magical glow, no dramatic summoning pentagrams. It was the raw, gut-deep violence of sped up cellular rebuilding. Arthur watched through his razor-sharp magnifying glass as the hairline fractures in Grimm’s old young skull knit shut with thick, stone-hardened stitch ridges. Along his spine, the dorsal spinous processes thickened. It laid down dense layers of calcium-phosphate matrix that possessed the pulling strength of hardened load-bearing steel.
Chunks of Grimm’s old, matted grey puppy coat began to slough off in ragged patches. It fell to the stone floor like burnt felt.
Emerging beneath was a dense, double-layered pelage of midnight-black glass fur. Each single hair fiber was barbed with tiny quartz dust scales, overlapping like fish armor, slick to the touch and fully non-flammable.
By three o’clock in the morning, the tremors subsided.
Grimm let out a long, shuddering sigh. His body cooled back down to a healthy thirty-eight point five degrees. He rolled onto his back with his paws tucked into his chest. He exposed his soft, pale belly to the ceiling, snoring with the deep, clockwork rhythm of an idling diesel generator.
Arthur wiped the cold sweat from his forehead with the back of his wrist. He activated his mental eye link, calling up the compact status screen to inspect the results of the night-hunting molt:
Arthur closed the screen with a faint smile.
Twelve point four percent purity. In less than forty-eight hours, a starved stray scheduled for the incineration fire had evolved into an apex Bronze C-Rank vanguard beast capable of withstanding small-arms fire and delivering over a ton of bite force.
Arthur pulled his cot blanket over Grimm’s sleeping form, tucking the wool snugly around his shoulders. He lay back down on his narrow mattress, folding his arms beneath his head, listening to the crackle of the embers and the soft, steady snoring of his two companions.
Tomorrow morning, the iron gates of Ironfang Vanguard Academy would open. The noble clans, the corporate cartels, and Dean Pendelton would be waiting.
Arthur closed his eyes, his breathing slowing to match the rhythm of the hearth fire.
Let them wait. The doctor was ready.
