"This is my town, metal-boy!" Harl screamed back, his voice cracking with rage as he hefted his timber-axe, the notched iron head trembling inches from Jarev’s unblinking, obsidian-tinted eyes. "My grand-uncle hammered the nails into these timber frames before your grandfather learned how to hold a pairing chisel! I’m not running from an imperial dog or a cursed smith!""You aren't running, Harl, you're just volunteering to be buried first," Jarev snapped back, his metallic shoulder plates grinding together with a harsh, metallic shriek that echoed off the damp stone walls. The hum of the embedded ore beneath his skin grew louder, a deep, resonant pitch that caused the water droplets hanging from the cavern ceiling to quiver and split. "Look behind you. The iron gate isn't going to hold another volley."A deafening, subterranean roar cut off Harl’s retort. The entire floor beneath their boots bucked violently, sending a cloud of choking grey dust billowing down from the low rafters. O

"Let them rattle," Kaedron snarled. He reached out with massive iron tongs, gripping the blazing, incandescent ingot straight from the heart of the hearth. The metal writhed against the grip, singing with an unholy, high-pitched shriek that made the blood in his ears pound like a war drum."Kaedron, the wall's cracking!" Lira screamed above the din, her hands flying across a row of earthenware jars as she frantically unstoppered a pungent, yellowish chemical compound and slathered it over the thick woolen cloth draped across the rear air vent. "If that acoustic resonance hits the main furnace wall at this frequency, the whole chimney stack is going to blow right down on top of us!""It’s not going to blow," Kaedron shouted back, his face slick with sweat, his knuckles stark white as he hoisted the blinding mass of white-hot steel into the air. "It’s going to sing back!"With a roar that tore from the very bottom of his lungs, Kaedron spun and plunged the entire fifty-pound mass of whi

"They aren't hitting it," Kaedron panted, his hands trembling as he let go of the heavy tongs and let them clatter against the stone floor. "Kald pulled the vanguard back. Did you see the square when the acoustic shockwave hit their lines? Half their vanguard dropped their weapons as if they’d caught fire.""They dropped them because the resonance shattered the molecular bond of the tainted ore," Lira said, her voice sharp and breathless as she rushed out from the back storeroom. She slammed a heavy, dust-covered ledger onto the workbench right between them, scattering a shower of gray soot. Her fingers were stained a deep, bruised violet from chemical reagents, and her eyes were wide with a manic, obsessive clarity. "I was examining the ore samples we pulled from the deep northern vein during the cave-in. Listen to me, Kaedron—we’ve been fighting this metal all wrong."Rhovan groaned, sliding down the side of the anvil block until he sat flat on the ash-streaked floor, clutching his

"My leg feels like it's full of hot needles, and I don't care what some dead miners wrote three hundred years ago unless it tells me how to stop Kald's next barrage," Rhovan snapped, his face tight with pain as he dragged himself up against the wooden workbench. "What did they find, Lira?""They found out it dissolves," Lira said, her voice dropping to an urgent whisper as she flipped the heavy, crackling parchment back. "It’s not magic, and it’s not just a stubborn alloy. It’s an iron-eating compound bound to a volatile mineral salt. If you douse the ore in a concentrated solution of common alkali and bitter-apple acid, the molecular structure doesn't just fracture—it unsticks. It rots from the inside out in a matter of seconds."Kaedron stared at her, the high-pitched ringing in his ears finally fading into a tense, suffocating silence. "You’re telling me all those weeks we spent breaking our backs trying to temper and smash that cursed metal...""We could have dissolved it with a w

"Well, his monsters are currently sitting three hundred yards outside our gate shivering in the frost, and I don't think they care much about vinegar," Rhovan rasped, leaning heavily against the timber post as he wiped his chin with the back of a calloused hand. "If Kald’s boys find out about this acid, they’ll just bring more lead-lined barrels. How much of this stuff do we actually have?""Enough for a single trench trap," Lira said, her fingers already flying across the margins of the ledger as she calculated the weight of the ink-stained reagents. "If we mix the bitter-apple stock from the apothecary's cellar with the potash from the lower smelter, we can flood the western approach right where the ram hits. The moment their vanguard steps onto the soaked earth—""It eats their boots and their blades right off their hips," Kaedron finished, a grim, humorless smile finally touching the corners of his mouth. "And leaves them standing in the mud with nothing to hide behind."Before Li
