The stench of burning bone filled Veldin's throat before the Headmaster even raised his sleeves. It was the exact smell from four centuries ago, beneath the shattered spires of Onde-Marr. He had knelt on cracked flagstones then, clutching Maeva's wrists while gold-rimmed pustules split her pale skin. Her flesh had sloughed into dry gray powder between his fingers. Every counter-reagent he threw at her sores had turned to glass, then to soot. He had watched her lower jaw collapse into cinder while she tried to speak his name. He had done nothing because he had known everything, yet mastered nothing that mattered. Now, Headmaster Thurn stood ten paces away, black ichor dripping from his gums onto silk collars. "She wept when she woke, Veldin," Thurn whispered. The old man's fingers bent backward at unnatural angles, the joints cracking like dry kindling. "Her mouth full of root-sap. Calling for her little prodigy." [Echo of Murmuris: The Mother’s vessel rejects severance. Re-establish conduit or suffer extraction.] "Be quiet," Veldin said. His voice was flat. The stoop in his shoulders vanished, his spine straightening until he towered over the broken glass beneath his boots. "You wear the skin of a scholar, Thurn, but you reek of an abattoir." Thurn chuckled, a wet, clicking rattle. "Kill me, then. Add my blood to the broth. It only thickens the marrow." The floor grates shrieked. Steel sheared off in jagged petals as seven marrow-fiends scrambled up into the sanctum. Their hides were slick, pale gristle stretched over spiked ribcages, their muzzles dripping with black bile. They were not mindless surface beasts; they bore the brand of Vask’s inner cauldrons burned into their skulls. "Seize him," Thurn commanded, stepping back into the shadow of the colonnade. "Leave the hands intact. The Mother requires his touch to finish the knitting." The fiends struck as one. The rush of air carried the freezing chill of the grave. Veldin pivoted, sweeping his sleeve to scatter a pouch of powdered brimstone, but two of the beasts caught his tunic. Bone talons ripped through wool and skin. He slammed hard against the petrified root, the impact driving the air from his ribs. The root’s filaments reacted instantly, latching onto his torn shoulder. Black needles pierced his collarbone, siphoning heat directly out of his core. His vision blurred with grease and violet light. [Conduit restored. Commencing final distillation of host grief.] His knees gave out. The familiar, hollow agony of Onde-Marr rushed into his veins, paralyzing his nerve paths. He couldn't lift his arm. He couldn't reach the vials at his hip. A fiend planted a clawed paw directly onto his chest, lowering its split jaw toward his neck. A sharp *churr* broke the air. From beneath Veldin’s torn collar, a ball of gray fluff shot straight into the fiend's open maw. Tuhk. "Tuhk, no!" Veldin choked out. The homunculus did not try to scratch or bite. Instead, the tiny creature opened its gullet, inhaling the torrent of black slime spewing from the monster's throat. The soot-body distended violently. Tuhk's rubbery skin went taut, turning from dull coal to a violent, veined purple. A sound like grinding millstones rumbled through the room. The creature expanded. Limbs of dense, hardened clinker burst from its tiny sides, knotting into thick pillars of volcanic slag. Where there had been a ball of soot no larger than an apple, a four-armed behemoth of compressed ash now crouched over Veldin. Tuhk roared—a deafening blast of compressed furnace air—and tore the attacking fiend entirely in two. Black marrow splattered the vaulted ceiling. The remaining beasts hissed, leaping toward the new threat. Tuhk met them with swinging fists of jagged basalt. Bone cracked. Gristle splattered across the flagstones. Tuhk took three gouging bites from the pack without yielding an inch, his glowing soot-armor sealing over the wounds by burning through the fiends' own toxic gore. "Abomination brewed from refuse!" Thurn spat from the dark, hurling a flask of acidic mercury that burst against Tuhk's shoulder, throwing up blinding white fumes. The homunculus stumbled, venting a shrill cry of pain. It bought five seconds. Five seconds was an eternity for a Grandmaster. Veldin grabbed the Charnel filament buried in his collarbone and tore it free with a shower of crimson. He brought his bloody hand to his mouth, biting his thumb to widen the gash. He didn't have his alembics, his gold-rimmed crucibles, or his balanced scales. He had his own circulating essence. *Forbidden Art: Blood-Cinnabar Ignition.* He blew across his palm. A fine spray of crimson droplets drifted into the humid air of the sanctum. As the mist touched the volatile mercury fumes and the festering rot, Veldin murmured a single, forgotten syllabic phrase from the Old Empire. The mist turned emerald. Then it ignited—not into flame, but into a microscopic chain of dissolving detonations that ate organic matter down to cellular grease. The five remaining fiends didn't even have time to howl; their limbs liquefied into pale broth, their skulls crumbling into calcium foam before their torsos struck the tiles. Thurn’s robes caught the vapor. The Headmaster shrieked, clawing at his own cheeks as the skin began to slide off his cheekbones like warm wax. "You cannot undo her! She is already rooted in the foundations!" "Run," Veldin rasped. He didn't wait to see Thurn die. He knew the Charnel Root would regenerate its puppet within minutes. Grabbing Tuhk by a massive, cinder-crusted forearm, Veldin dragged the beast toward the heavy iron grate of the upper ventilation shafts. With a heave of failing strength, Veldin wrenched the emergency lever. A four-ton blast door dropped behind them with a ground-shaking clang, severing the sanctum and the shrieking voice of Thurn from the narrow, pipe-lined passage. Silence crashed down, broken only by the hiss of distant steam pipes. Veldin collapsed against the curved zinc wall of the conduit, his chest heaving, his boots soaked in gore. "We made it. Tuhk. Good boy. We got clear." A wet, rattling heave answered him. The hulking, soot-armored guardian did not stand proud. Its massive limbs began to flake away, shedding slabs of dead slag like dry bark. The bulk collapsed inward with a sickening squelch. Within moments, only the tiny, fragile bundle of ash remained on the cold metal floor. Tuhk curled into a tight knot, shivering violently. From its blunt, soot-lined snout, a pool of viscous black bile bubbled out, sizzling against the zinc plate. The same divine rot that had killed Maeva was now eating the little creature from the inside out.
