The transition from the blinding white heat of Nate McCoy’s forge to the freezing, rain-slicked alleys of the harbor fringe was like plunging a red-hot blade into brackish ice.

Nate had slammed the heavy iron bar across the forge door, his three-fingered hand white-knuckled as he screamed over the rising din of the Sea-Stricken mob outside. *“Take the coal chute! Go! If they find you here, they’ll melt those chisels down to slag!”* Caleb had not hesitated. Dragging Abigail Vance by her damp wool coat, he had tumbled through the narrow, soot-choked chute into the freezing mud of the alley, the dark, star-iron veins of his reinforced carving kit tucked securely under his left arm.

Now, the rain fell in relentless, freezing sheets, washing the black soot from Caleb’s face but doing nothing to soothe the agonizing, second-degree burns on his left hand. He kept his hand wrapped in tattered linen, the raw skin weeping against the coarse fabric. His right arm was a dead, heavy column of bark-grey ashwood, hanging stiffly from his shoulder. When his wooden knuckles bumped against his thigh, they made a flat, hollow *clack*—the sound of a dead branch knocking against a headstone in winter.

*Tick. Tock. Tick. Tock.*

Beneath his salt-stained canvas apron, the mechanical ticking in his chest was loud, a slow, dry clockwork that seemed to wind down with every frantic step they took through the purple fog. The fog was growing thicker, smelling of copper and rotting kelp, a toxic sign of the waking deep.

“The secondary foundry is just ahead, behind the salt-crusted walls of the fish-processing plant,” Abigail whispered, her voice a shivering thread of sound as she huddled against a rotted timber piling. Her fingers, stained with the cobalt of her sacred pigments, clutched her paintbox to her chest. “My father’s enforcers have locked down the main gates, but the sewer outfall is clear. If Thomas is inside, he’ll be at the master crucible.”

Caleb did not answer. He looked at her with his pale grey eyes. Through his monochrome right eye—the one locked in a cold, grey haze by the creeping petrification—the world was a shifting canvas of high-contrast silhouettes. He could see the faint, pulsing purple currents of the fog, but the warmth of his memory was entirely gone. He looked at Abigail’s face, knowing she was his ally, yet his mind was a blank slate. He could not remember the sound of his mother’s laughter, nor could he picture his grandfather’s face. Only the desperate, instinctual drive to protect his sister Clara remained, a solitary pillar of fire in the dark, hollow ruins of his mind.

“We move silent,” Caleb rasped, his voice a dry, gravelly whisper. “Nate’s steel is tempered, but my hand is stiff. If we draw a crowd, we won’t make it to the altar.”

They slipped through the rotted iron grate of the sewer outfall, crawling through a narrow brick conduit coated in black grease and dead barnacles. The air inside was suffocating, thick with the stench of coal gas, sulfur, and molten brass. As they emerged into the subterranean level of the foundry, the heat hit them like a physical blow.

It was a hellish, cavernous vault of black brick and iron dust. In the center of the room, a massive stone crucible bubbled with liquid brass, casting a sickly, yellow glare against the soot-stained rafters. Hanging from the ceiling on heavy iron chains were dozens of cheap, mass-produced brass masks, their hollow eyes staring blankly in the dim light.

Standing before the master anvil was the Hollowed Blacksmith.

Thomas, Nate’s former apprentice, was a muscular young man, but his body was horribly changed. His skin was pale and slick, covered in rough patches of grey fish scales. His face was entirely concealed by a heavy Golden Mask of the Initiate, the gold-plated brass bonded to his skin, silver leafing tracing his jawline like a parasitic vine. He worked in a mindless, rhythmic trance, his heavy forge mallet rising and falling on a glowing brass plate with a deafening, mechanical *CRACK... CRACK... CRACK*.

Caleb’s left hand tightened around the hilt of his grandfather’s straight-edge chisel. The star-iron veins along the steel edge hummed with a cold, starlight warmth, reacting to the presence of the cult’s corrupt metal.

“He’s using the stolen Thorne template,” Abigail murmured, pointing to a charred piece of vellum pinned to the brick wall behind the anvil. “Julian’s golden replica... if he completes that mask, Silas will have the tides.”

“I have to disable the bellows,” Caleb whispered. “If the furnace cools, the template is useless.”

Caleb stepped out of the shadows, his boots making no sound on the soot-slick floor. He reached for the heavy iron valve of the coal-gas line, intending to cut the fuel. But as his burned left fingers touched the hot metal, his stiff right shoulder gave a sharp, scraping creak.

The sound was minor, but in the rhythmic silence of the forge, it was a gunshot.

Thomas’s hammer stopped mid-swing. The glassy, reflective slits of his Golden Mask snapped toward the corner. A wet, guttural growl rumbled from his throat, a sound that was entirely non-human, filled with the low-frequency vibration of the deep.

Without warning, the brainwashed smith lunged. He did not grab his mallet; instead, he snatched a massive, glowing, red-hot iron bar from the furnace coals and swung it in a lethal arc toward Caleb’s head.

Caleb’s instincts, honed by generations of carvers who fought in the dark, took over. He knew his stiff joints could not dodge the strike in time. He thrust his petrified right arm forward, using the solid, bark-grey ashwood limb as a shield.

*CRACK.*

The glowing iron bar slammed directly into Caleb’s forearm. A thick plume of white smoke erupted from his grey skin, smelling of scorched pine and wet ash. The intense heat blistered his collarbone, but the petrified wood-flesh did not break. It absorbed the crushing impact, the star-iron veins in his duster sleeve absorbing the physical shockwave.

Thomas roared in frustration, dropping the bent iron bar. He seized his massive, forty-pound forge mallet with both hands, swinging it downward with a monstrous, heat-resistant strength that shattered the nearby wooden storage racks into a shower of sharp splinters and heavy timber blocks.

Caleb stumbled backward, the wet, soot-slick floor threatening to take his footing. He executed the *Tide-Reading Stride*, his eyes reading the wet sheen of coal oil and brackish water on the basalt floor like a tide-pool. He found perfect traction on the slippery stone, his feet moving in a fluid, rhythmic pattern that allowed him to slip past the falling debris and close the distance.

He reached into his pocket with his left hand, pulling a small, weighted carving chisel. He threw it with a rapid, snapping motion of his wrist, targeting the eye slits of the blacksmith’s mask.

*CLANG.*

The heavy brass mask deflected the steel blade with a sharp, ringing vibration. The chisel skittered across the floor, lost in the dark coal dust.

“Caleb, watch the furnace!” Abigail screamed.

Thomas charged like a maddened bull, his massive shoulders slamming into Caleb’s chest and pinning him against the red-hot brick wall of the furnace. The intense thermal radiation threatened to burn through Caleb’s duster, his skin screaming as the heat reached his collarbone. The petrification on his chest began to tick frantically—*tick-tick-tick-tick*—a rapid, wooden alarm.

Thomas raised his heavy mallet, preparing to crush Caleb’s skull.

In the suffocating heat, Caleb did not panic. He recalled Nate’s warning: *All mass-produced golden masks have a structural fault line at the bridge of the nose where the gold leafing is thinnest.* By targeting that cognitive anchor, he could shatter the mask’s control without inflicting lethal brain damage.

Caleb tensed his body, using the density of his petrified right arm to wedge himself against the brick wall, absorbing the crushing physical pressure of the blacksmith’s grip. With his raw, burned left hand, he drew his reinforced star-iron chisel from his belt.

He drove the chisel’s tip directly against the bridge of Thomas’s brass mask.

“For Nate,” Caleb rasped.

He raised his petrified right hand—locked in its heavy, rigid wooden claw—and drove it down like a massive mallet onto the butt of the star-iron chisel.

*The Heartwood Strike.*

A sharp, deafening crack echoed through the cavernous foundry, followed by a shockwave of cold, starlight energy that rippled from the meteoritic iron blade. The heavy brass mask split cleanly down the center, the cheap gold leaf peeling away like dead skin.

Thomas froze. His hands dropped the mallet, the heavy iron tool crashing into the soot. The Golden Mask shattered into pieces, clattering against the basalt floor.

Thomas collapsed into Caleb’s arms, his skin pale and shivering as the dark, oily veins on his neck began to fade. The glassy, vacant stare in his eyes cleared for a brief, tragic second. He looked up at Caleb, his lips trembling as he recognized the star-iron chisels of the Thorne lineage.

He drew a wet, rattling breath, his fingers clutching Caleb’s canvas sleeve with his remaining strength.

“The Chapel...” Thomas rasped, his voice a dry, dying wheeze. “Silas... he knows where she is. He sent Grimsby... St. Jude’s is falling...”
