The procession moved through the torchlit corridor. Men and women in rags, bound at the wrists by iron chains, shuffled forward in a single file, their hollow eyes fixed on the stone floor. Cult members in dark robes flanked them on either side, wordless and efficient, herding the prisoners the way a shepherd herds livestock.
At the front of it all stood Stone, the Overseer.
He stood just inside the entrance of the Head Priest's laboratory, lips moving faintly as he counted each prisoner that crossed the threshold. His eyes moved with mechanical precision, tracking each body.
When the last prisoner passed him, he turned his gaze to tally the numbers in his head and gave a slow nod of satisfaction.
He stepped outside the laboratory door and met one of the robed figures waiting in the corridor. He spoke quietly.
"That's enough. Go tell the others — we have sufficient numbers. Send the rest back."
The figure dipped their head beneath their hood and disappeared into the dark of the corridor without a word.
Stone turned back to face the laboratory. The prisoners knelt or sat against the walls, chains pooled around them like iron roots. Some stared at the ceiling. A few trembled. None spoke.
"The rest of you," Stone called out flatly to the robed figures still lingering inside, "can leave."
He let the words settle for a beat.
"Unless, of course, any of you are willing to volunteer as test subjects." He tilted his head slightly. "In that case — by all means, stay."
The robed figures did not need to be told twice. There was a brief, undignified scramble as they moved for the door — careful not to run, but walking at the very edge of running. Stone watched them go with the blank expression of a man who had seen it before and expected nothing less.
He caught two of them by the shoulder before they could slip out.
"You two. Stay at the door. No one enters."
They nodded, taking their positions on either side of the heavy iron doors as Stone pulled them shut with a low, resonant *boom* that echoed through the stone chamber.
Silence settled.
Then the wall opened.
A section of the laboratory's far stone wall split apart without sound, revealing a narrow passage behind it. From the dark of that passage stepped Boros.
He was still wearing his human form — a tall, composed figure with an unnervingly still quality to his movements, like a predator that had learned to mimic patience. Over his dark shirt and deep blue vest he had draped a white doctor's coat, pressed and clean, which stood in quiet contrast to the grime of the chamber around him. A red tie sat at his collar with deliberate precision. Combat gloves covered his hands. Dark trousers. A stethoscope hung around his neck with the casual ease of a man who had worn one for years.
He walked toward the prisoners without hurry, his expression unreadable — not cold, not warm. Simply absent of anything unnecessary.
From the floor at Stone's feet, a shadow stirred.
It stretched forward like something alive, thin and dark across the stone, until it reached the leg of the large desk near the center of the lab. Then, from the shadow itself, a figure emerged — stepping out of darkness the way a person steps out of a doorway, smooth and unhurried.
Yelan landed lightly on the desk, crossed one leg over the other, and adjusted the front of her cult robe, which hung open to reveal the skin-tight assassin's suit beneath. She looked around the lab with mild curiosity.
Her eyes found Boros.
"I thought you couldn't control the old man," she said, nodding toward Stone.
Boros stopped walking. He turned — and found Stone already standing before him, hands clasped behind his back, posture rigid with a kind of enforced deference.
"Head Priest," Stone said. "All preparations have been made."
Boros looked past him. Along the far wall, an operation table had been arranged with the thoroughness of a surgeon's theatre. Instruments lay in precise rows — scalpels, retractors, bone saws, clamps — all of them clean, all of them waiting. Nearby, a secondary table held glass containers, measuring tools, and materials whose purpose was less obvious and more troubling.
Boros looked at it for a long moment. The faintest trace of a smile crossed his face.
He turned to Yelan.
"It took me all morning," he said, "but I was finally able to rewrite his perspective. A slight alteration to his memory. Nothing dramatic."
He moved toward the operation table.
One of the prisoners had already been secured to it. A middle-aged man with a broad build. He stared at the ceiling with the glassy stillness of someone who had run out of prayers.
Boros looked down at him expression, calm but eager. He reached for a scalpel from the instrument tray, held it up briefly in the torchlight, and turned it once between his fingers.
"That's nostalgic," he said quietly.
Then he began.
He worked from the top — a precise incision along the coronal suture, peeling back the scalp in measured sections before applying a bone saw to the cranium with a steadiness that suggested he had done this many, many times before. The skull opened in two clean halves. He examined the brain matter beneath with detached curiosity, tracing the visible structures with one gloved finger as if reading a map he mostly recognized.
From there he moved to the chest. He split the sternum with practiced efficiency, spreading the rib cage with a retractor until the thoracic cavity lay fully exposed. The heart continued its work — stubborn, rhythmic, indifferent to the violation. Boros studied the organ, its surrounding vasculature, the way the lungs expanded and collapsed, and made small notes in his head the way a scholar marks margins.
He moved lower. The abdominal cavity came apart under his instruments with the same cold precision — peritoneum opened, viscera carefully displaced and examined, the complex arrangement of the digestive system mapped and noted. Where the anatomy matched what he knew, he moved quickly.
By the time he finished, his white coat was still pristine but his gloves were soaked through with dark red. He straightened, stepping back from the table, and raised both hands before his face.
He stared at them.
For just a moment — barely a second, like a light flickering in a storm — his hands changed. The gloves dissolved. The skin beneath rippled and shifted, the fingers elongating, the surface losing its human texture entirely before snapping back to shape. Clean gloves. Unmarked skin. As if the blood had never been.
He lowered his hands.
Boros looked back at the man on the table, who — against all reasonable expectation — was still breathing. Shallowly, barely, but breathing.
*Fascinating.*
*Setting aside the resilience — which is remarkable — the basic anatomy is not so different from the humans of my world. The organ systems, the structural logic, the chemistry of the blood. The gap is smaller than I expected.*
*But the mana pathways are another matter entirely.*
He reached for a fresh instrument, his eyes moving along the interior of the exposed chest cavity, searching.
*The channels that allow them to use magic — I remain utterly clueless. Except for a vague impression of its presence. But I cannot yet determine the mechanism.* He pressed his fingertips together, thinking. *I need more time. More subjects. More data.*
"I've been meaning to ask."
He blinked. Yelan's voice cut through his analysis like a needle through cloth.
"Those clothes you're wearing." She was watching him from the desk, her chin resting lightly on one hand. "You made them from your own skin, didn't you."
"Yes," Boros said simply. "Why?"
Yelan held his gaze.
"Doesn't that mean you're completely naked right now?"
The laboratory went very quiet.
The torches crackled. Somewhere behind them, Stone methodically unfastened the restraints on the man on the table and began forcing another prisoner forward to take his place — calm, practiced, entirely unbothered.
Yelan looked at Boros.
Boros looked at Yelan.
Neither of them said anything.
"...Forget I said anything," Yelan said at last, looking away.
Stone secured the new subject to the table and stepped back without a word. This prisoner was younger — lean, with dark eyes that darted frantically between Boros and the instruments and the opened remains of the man being quietly moved aside.
Boros approached.
He worked with the same precision as before, but this time his focus was different — narrower, more deliberate. He made a single long incision down the subject's back, then began separating the skin from the subcutaneous tissue beneath with the careful patience of someone unfolding a document they did not want to tear. Layer by layer, the dermis came away clean — the subject's voice rising and then breaking and then going silent as something in them made the decision to go somewhere else in their mind.
Boros lifted the skin and held it up to the torchlight, turning it slowly, studying the inner surface with the same expression a craftsman uses when evaluating raw material.
"What are you planning to do with that?" Yelan asked. She was trying to sound unbothered. Almost succeeding.
"Wear it," Boros said.
"You want to wear human skin?" Yelan asked, shocked.
"What's the difference between that and wearing animal skin?"
Yelan opened her mouth. Closed it. Opened it again.
She had no answer. Logically there was no difference. She knew that.
She looked at him and for a moment, just beneath the white coat and the red tie and the careful human shape of him, she saw the silhouette of the monster she was truly speaking with.
Then it was gone.
Boros had already set the skin flat on the floor and was lowering himself in front of it, crossing his legs. He extended his right hand forward, supporting his wrist with his left, and held the position for a moment — fingers arranged in a precise configuration, joints locked, the whole gesture carrying the weight of something rehearsed over a very long time.
Then he began his chant.
His voice deepened, returning to a hollow shriek for a moment resonating not loud — barely above a murmur — but it *carried*, pressing against the walls, settling into the spaces between the stones.
Nigredo: The Blackening
"In the mouth of the serpent, all things end.
Strip away the shape; return the soul to the dark.
What was whole must now rot.
Solve et Coagula.
I call the void: Return Prima Materia."
The skin on the floor changed. The colour darkened like decaying flesh, rotting, until what lay there was a black mass, lightless black — a distortion in space—Dark Matter.
Albedo: The Whitening
"The shadow dies; the silver dawn rises.
Wash the ash in the lunar tide until only truth remains.
Cold light, burn away the dross.
Through the cycle, be reborn.
Purify the soul."
The Dark matter began to pale. Silver-white rose from the center, moving against the torchlight, casting no reflection. The shape on the floor seemed to breathe — to contract and expand in a rhythm that had nothing to do with air.
Rubedo: The Reddening
"The tail meets the head; the circle is closed.
From the white snow, the red sun wakes.
The blood of the dragon is the life of the Cosmos.
Nothing is lost, everything is one.
Achieve the Great Work."
Magnum Opus
The last word left his mouth and the room held its breath.
Then — quietly, without spectacle — the light settled.
Where the skin had been, a set of clothes lay folded on the stone floor. A white doctor's coat. A dark shirt. A deep blue vest. A red tie. Combat gloves. Pressed trousers. Every piece identical to what Boros was wearing.
He stood slowly. He raised his arms and turned his head — a full rotation, all the way around, far past what a human neck allows — observing his form, confirming what his mind already told him.
*I lost considerable mass for something this simple,* he noted internally, with mild dissatisfaction.
"What," Yelan said, "did you just do."
She was standing now. She had moved without realising it. She was staring at the folded clothes on the floor, then at him, then at the floor again.
Boros considered the question with genuine thought — the way he always did when something he considered ordinary apparently wasn't.
"It's similar to what you would call alchemy," he said.
Yelan shook her head. Sharp. Certain.
"I've seen alchemy before." Her voice was quieter now. Not frightened, just unsettled. "It looked nothing like what you just did."
Boros looked at her.
"Huh."
