The sub-basement of the Voss Crystalline Sanatorium was not a hospital. It was a high-pressure machine that used human bodies as copper windings.
Ren Vale reached the bottom of the granite stairs, his boots sinking into an inch of oily water that covered the floor. The air was freezing, twenty degrees colder than the hall above. But it carried an unnatural, dry heat that prickled against his skin like static electricity. Overhead, huge copper channels ran along the vaulted ceiling, their joints sweating green rust as they carried boiling town steam toward the district heat exchangers of the High Spire.
And beneath the copper pipes lay the wards.
Twenty-four iron cots were bolted to the damp flat stone slabs in two parallel rows. Each cot was surrounded by a frame of heavy brass rods wrapped with padded gutta-percha wire. Heavy iron collars clamped the necks, wrists, and ankles of the patients to the timber frames. That kept them rigidly immobile.
Ren took three steps into the room and stopped, his breath catching in his throat.
These were the end-post patients of Low-Khorat. Weavers, dockworkers, back kitchen maids, and children whose families had bankrupted themselves paying Julian Voss’s ‘curative fees.’ None of them were being cured.
In every single cot, the turning to glass had advanced far beyond Mira’s stage. On the nearest bed lay an elderly dyer whose entire torso had turned into a faceted slab of semi-clear amethyst. His skin had split along the chest bone. He showed a ribs of solid, linked purple quartz that pulsed with rhythmic, underground light. Copper wires were soldered directly into the crystal lattices of his collarbones, running upward into the ceiling channels.
The steam pressure in the copper pipes surged overhead. Each time, the crystal in the man’s chest flared with blinding violet light.
Hummmmm-chime.
A sound like forty cathedral bells being struck at the same time under water rolled through the chamber. The air shook with a ringing drone so dense that Ren had to brace his hand against a damp brick pillar to keep his balance. The sound deep ring shook through his boots. It set up a sympathetic ache in his teeth, his skull, and the bruised bone of his ribs. His lungs hitched, feeling the phantom pressure of glass-like crystal-forming trying to take root in his own lung passages.
Beside him, Vane Vale stood perfectly still. The merchant’s high-born composure had vanished, replaced by an expression of cold, poisonous fury that made his grey eyes look like shards of flint.
“Pressure-sparking dampening,” Vane said, his voice flat, dead, and lethal. “The high-pressure steam from the central earth-heat wells carries uneven thaumaturgical spikes. If you pipe it directly into the high-born district, the pressure fluctuations burst the bronze pipes and melt the brass radiators. But if you run the channels through ringing glass-like quartz...”
Vane pointed his cane at the row of cots.
“The crystal-clear tissue absorbs the excess pressure,” Vane continued, his knuckles white against the gold metal ring. “It converts the chaotic heat energy into stable deep ringing hum. They’re using these people to heat the dining rooms of the High Spire without spilling Lord Malakor’s soup. A human heat sink, amortized over twelve months of agony.”
Ren walked down the central aisle between the cots.
His boots splashed softly in the standing water. He looked into the faces of the patients. Most were unconscious, their eyes clouded with the milky clouded eye of turning to glass, trapped in a deep, frozen stillness-induced coma induced by packed poppy extract. But as he passed the twelfth cot, a small hand twitched.
It was a young girl—no older than eleven—her slender frame swaddled in a stained hospital gown. Her right shoulder, arm, and the entire right side of her neck had turned into smoky quartz, matching to Mira’s. Her left hand was free, though weakly chained to the bedrail with a thin copper wire.
Her eyelids fluttered open, revealing pupils that were flecked with violet sparks.
She looked at Ren.
“Is the train here?” she whispered. Her voice was not human. It carried the thin, sound ring of a struck tuning fork. It echoed with unnatural clarity off the brick vault. “The master said... When the train comes, the singing stops. He said... We get to go to the garden in the sky.”
Ren knelt in the oily water beside her cot, ignoring the filth that soaked through his wool trousers. He reached out with his warm, ink-stained thumb, gently wiping a streak of dried tears from her hollow cheek. Her skin was freezing, cold as river ice.
“The singing is going to stop, little one,” Ren promised. His voice shook with a rage so pure it burned the back of his throat. “I swear it on my father’s grave. The train is never leaving the station.”
“Elsie,” she murmured, her eyelids drooping. “My name is Elsie. Tell my brother... The bluebells are pretty.”
The girl’s eyes drifted shut again, lulled back into the poppy-haze by the rhythmic hum of the copper pipes.
Ren looked at the head of Elsie’s cot. Nailed to the wooden post was a tin clipboard holding a parchment card stamped with the red seal of the High Spire. It read: Consignment Parcel 18 — Weight: 54 lbs. Target Hum: 440 Cycles (Smoky Quartz, High Purity). Designated Recipient: Lord Malakor, Private Breath-mask Car.
Next to her cot, on cot thirteen, the mattress was stripped down to the bare straw. A fresh tin clipboard hung on the post, blank except for a newly inked line: Consignment Parcel 19. Reserved: Mira Vale (Stage 3). Intake scheduled: Dec 21, 04:00.
Ren stared at the blank card. His vision swam with black spots. The blood roared in his ears louder than the steam channels. If he hadn’t broken into the archive, Mira would be lying on that straw right now, copper wires soldered into her collarbone. He waited for the butcher’s wagon.
He looked along the brick wall behind the cots. Pinned to an oak drafting board were technical schematics rendered in white ink on cyan-treated rag paper. The title read: Ringing Steam-Breath-mask, Mark VII — Patent Holder: Malakor Ironworks. The diagram depicted a fine, detailed brass chest harness fitted with air-powered pistons and a central chamber where a glass-fused human forearm was clamped into an airtight quartz sleeve to dampen pressure oscillations.
“He designed the machine around her,” Ren whispered, his voice shaking with nausea. “Malakor didn’t buy her at auction. He ordered her six months ago. The whole clinic... It’s a bespoke harvesting yard.”
Vane walked up behind Ren, his shadow stretching long and dark across the row of cots. The older man pulled a brass watch from his waistcoat, checked the dial. Then he snapped the cover shut with a sharp click.
“Thirty-five minutes until the morning watch,” Vane said quietly. “The shipping manifest is in the medicine room office at the end of the aisle. We find the crate assignment for Mira, we copy the transport codes. We get out before Voss arrives for the morning forced payout.”
Ren rose from the water, his fists clenched tight at his sides. He looked at the twenty-four cots, at the copper wires draining the life from their marrow to heat the palaces of the rich.
“We can’t leave them here, Vane,” Ren said, his voice choking with desperate urgency. “Look at them! They’re alive! We can cut the copper wires! We can break the iron collars with my awl! If we flood the steam pipe hub, we can force the guards to evacuate the cellar!”
Vane looked at him. For a long, painful second, the older man’s face was an open wound, torn between the ruthless pragmatism of the merchant who had abandoned his sister and the terrible, burning guilt that had pulled him from the ash of the mirror.
“We have two hands, Ren,” Vane whispered, his voice cracking with old grief. “We have one awl, four sheets of thick parchment, and thirty-two crowns we already gave away. If you cut those copper wires now, the steam pressure in the district channels will surge. The safety valves in the street above will blow, three companies of city watch will be on this basement in five minutes. You’ll die in this ditch.”
Vane reached out, gripping Ren’s shoulder with an iron grip that bit through his wool coat.
“Win the train first, boy,” Vane hissed into his ear, his eyes wild with desperate fury. “If the train doesn’t move, the harvest has nowhere to go. If we take down the Solstice Express, Malakor’s contracts are broken, Voss’s buyers vanish. The High court will have to impound this entire hospital. First the ledger. Then the train. Then the butcher.”
Ren took a slow, deep breath of the rotten-egg, static-charged air. He looked at the ivory awl in his palm. The four inches of fossil mammoth tusk were cool against his sweating skin. Every legal principle he had learned under Old Vellum Corley told him that an unbonded seizure was suicide. Justice in Khorat was not an act of passion. But an iron lever applied to a precise lawful pivot point.
“First the ledger,” Ren agreed, his voice settling into cold, unchanging granite. “Show me the medicine room.”
They turned toward the heavy iron-banded door at the far end of the ward. Their boots splashed through the dark standing water, while behind them, the twenty-four living batteries hummed their endless, clockwork dirge.
