The alley where they had found him three months ago hadn't changed.
Same cracked walls. Same patch of damp in the left corner. Same smell — old stone and standing water and something else with no name.
Yan Ku stood in the middle of it and looked at the ground.
No trace. Of course there was no trace — three months of rain had washed everything away a dozen times over. But he hadn't come looking for physical evidence.
He came to think.
He extended his right hand in front of him and stared at the back of his palm. In the pale daylight the mark was nearly invisible — thin lines beneath the skin, undetectable unless you knew exactly where to look.
What are you?
No answer. The mark was silent as always.
He tried what he had tried twenty times over three months — focus, imagine energy moving, imagine warmth, imagine anything. Nothing happened. Same as always.
He exhaled slowly.
Fine. Different angle.
What did he actually know about Khen? Four years of civil investigations had taught him the basics — not because he'd wanted to learn, but because understanding crimes required understanding how power worked.
Khen needed three things: will, memory, and bone.
Will was the fuel. Memory was the price. Bone was the vessel.
But his inscription hadn't taken a memory with his consent — it had taken one by force that night. Four complete hours. Gone.
So the price was paid in advance.
He stopped on that thought.
In everything he had read about Khen, the practitioner chose which memory to give. That conscious choice was what allowed the inscription to settle without killing its host. But his mark had given him no choice. It had taken what it wanted.
And I lived.
While Orev Tash died.
The only difference Seira had told him — his bones accepted the inscription and Tash's bones rejected it.
Why?
He sat down against the wall, not caring about the cold or the damp.
He thought.
Rejection and acceptance in Khen came down to compatibility — as if every inscription had a language, and every set of bones had a dialect. When they matched, the inscription settled. When they didn't —
You died.
So his bones spoke the same language as this inscription.
A language no one can read.
Seira had said it plainly. Thirty years of experience and she had never seen it before. And Wei — the old man who had saved him — had spent three days trying to read it and failed.
But Yan Ku didn't need to read it.
He just needed to turn it on.
He stood and took out the small blade from his coat pocket — standard issue for every district investigator, used for opening locks and collecting samples. He held it in his left hand and looked at the back of his right.
This is going to hurt.
He pressed the tip of the blade lightly against the skin directly over the mark.
He didn't cut — just pressed. He wanted to feel. He wanted to know if there was any reaction.
For a full second nothing happened.
Then the warmth.
Not burning — warmth. Like something beneath the skin had woken slowly from a deep sleep and looked around.
He pulled the blade back immediately.
The warmth lasted two more seconds then faded gradually until it was gone.
So you feel things.
He looked at his hand with fresh attention.
Not a dead tool. Something inside it responded to external contact. Responded to pressure. Maybe —
"That's not the right way."
A voice from above him.
Yan Ku looked up. On the edge of the rooftop next door — two full floors up — a boy was sitting with complete ease, legs dangling in the air, eating an apple without any particular concern.
Fifteen years old at most. Worn clothes. Messy hair. But his eyes were watching Yan Ku's hand with a kind of knowledge that had no business belonging to his age or his appearance.
"Who are you?" Yan Ku asked.
"Someone who knows Khen." The boy climbed down from the roof — not dramatically, just scaled the wall quickly and naturally and landed in front of him. "I watched you pressing a blade against it. That's like trying to start a fire with water."
Yan Ku studied him carefully. Worn clothes but good shoes — the kind of contradiction that meant someone choosing to hide, not someone actually poor. No visible inscriptions on his hands but the way he held his body said he knew exactly how to use it.
"You've been watching me," Yan Ku said.
"Half an hour." The boy finished his apple and tossed the core aside. "I was waiting to see if you were smart or not."
"And?"
"You're not stupid." He said it like a neutral assessment. "But you're thinking like an investigator about something that doesn't work by investigation logic."
He sat cross-legged on the ground in front of him like he owned the alley.
"Khen doesn't respond to external pressure," he said. "It responds from the inside. You're knocking on the door from the outside. The door only opens from the inside."
"And how does it open from the inside?"
The boy looked at him. "Through loss."
Yan Ku said nothing.
"The inscription took a memory from you. Four hours, right?" The boy kept his eyes on the mark with genuine focus. "That's a massive price for a first inscription. Means whoever put it there expected to give you something enormous in return." He paused. "Your bones didn't just accept it. They were waiting for it."
"That's not possible."
"I know." The boy said it simply. "But here we are."
Yan Ku looked at him for a long moment. "How do you know all this?"
"Because the same thing happened to me." Quietly. "Three years ago."
Yan Ku didn't ask more than that. The tone made it clear this wasn't the moment for those questions.
"So how do I reach it?" he asked instead.
The boy stood. "Come with me."
"Where?"
"Somewhere you can practice without bringing the wrong attention." He started walking. "Or stay here and keep poking yourself with a blade."
The place the boy took him was an abandoned warehouse near the old harbor. Thick walls, sealed windows — exactly the kind of place built for things nobody wanted heard from outside.
In the center of the floor were carved circles. Old ones — some blurred by time, but still there.
"Training floor," Yan Ku said.
"Was. Fifty years ago." The boy sat in the corner. "Nobody comes here now except me."
"Your name," Yan Ku said.
"Rei."
"Just Rei?"
"For now." He looked at him. "Now listen. The inscription works through loss — but not a new memory loss. The mark that took your four hours runs on that payment. It's already been made. You don't pay again." He leaned forward slightly. "You just need to reach what it bought you."
"And how do I reach it?"
"By focusing on what you lost," Rei said. "Not trying to remember it — that won't work. Focus on the absence itself. The gap it left. The feeling of reaching for something in the dark and finding nothing there." He paused. "The inscription lives in that exact gap."
Yan Ku looked at him with narrowed eyes.
"How old are you?" he asked.
"Fifteen."
"You talk like someone much older."
"Loss does that." Rei said it without drama. Just fact.
Yan Ku didn't respond to that. He stood in the center of the carved circles. Closed his eyes.
He thought about that night. The four missing hours.
He didn't try to remember them — like Rei said, that was useless. Instead he focused on the gap itself. On the strange feeling he got every time he tried to reach those hours — like extending his hand in the dark to grip something that simply wasn't there.
The absence.
Yes. There was something in that absence.
Not memories — something else. A faint warmth. A quiet pulse. Like something sleeping at the very bottom, breathing so slowly you could only catch it if you stopped everything else first.
You're there.
The warmth in his right hand returned. This time without the blade. Without any external pressure.
From the inside. Completely.
Yan Ku opened his eyes.
The lines beneath his skin were glowing. Not brightly — softly. But they were alive in a way they had never been before.
"Good." Rei's voice from the corner was completely flat. "That's the first step."
"How many steps are there?"
Rei looked at him.
"I don't know," he said with an honesty that was more unsettling than any other answer would have been. "Your inscription doesn't have a known map."
Yan Ku let the glow fade slowly. Watched his hand return to normal.
So that's you.
He still didn't know what it did. Still didn't know its range or its cost or what it was capable of. He still didn't know why Lord Casven had spent two years and eleven lives searching for someone who could carry it.
But he knew one thing now that he hadn't known this morning.
He could reach it.
And in a city where the wrong people already knew his name — where a man above the clouds had decided he was either a weapon to claim or a problem to bury — being able to reach it was the difference between being hunted and being dangerous.
He closed his hand slowly.
Start there, he told himself. Everything else comes after.
