Wei's list had four names on it.
He had written it the morning after Rei's arrival, in the careful handwriting of someone who had been composing the list in his head for longer than he was willing to admit. He set it on the table between them without explanation and let Yan Ku read it.
Four names. Four brief descriptions beside each one. Occupations, districts, one or two lines about what Wei knew of their circumstances.
Yan Ku read through it twice.
"You've been thinking about this for a while," he said.
"Twenty years is a while," Wei said. He sat down and wrapped both hands around his tea cup. "Isara wasn't the only one who understood what the network could be used for. I understood it too. The difference is that she did something about it and I spent two decades telling myself I was waiting for the right moment." He looked at the list. "These are people I've been observing for various lengths of time. People whose — quality of attention, let's say — suggested to me that they might be compatible with the old forms."
"Quality of attention," Yan Ku repeated.
"The same thing that made you compatible," Wei said. "The ability to hold multiple threads simultaneously without losing the center. To be present in complexity without being consumed by it." He paused. "It's rarer than you'd think. Most people, when faced with too much information arriving too quickly, do one of two things. They shut down or they fixate. The people on that list do neither."
Rei was reading over Yan Ku's shoulder. "How did you find them?"
"The tea house," Wei said simply. "People talk in tea houses. And a man who has spent twenty years with nothing to do but observe people in tea houses gets fairly good at recognizing certain things."
Yan Ku looked at the first name on the list.
Maren. Female. Late twenties. Works as a cartographer for the district survey office. Has been mapping the lower districts' underground passage network as a personal project for approximately three years.
He looked up. "She's been mapping the passages."
"Independently. No connection to Casven's network that I've been able to determine. She started because she found a discrepancy in the official survey maps and it bothered her." Wei's voice carried a trace of something that might have been appreciation. "She's been quietly correcting the official record in her own time for three years because the inaccuracy bothered her and she didn't trust anyone else to fix it."
"She knows the underground," Yan Ku said.
"Better than almost anyone in this city." Wei paused. "Better, probably, than Casven's people do."
Yan Ku set the paper down. He looked at the second name.
Dov. Male. Thirties. Former Middle Sky administrative clerk. Left the Middle Sky seven years ago under unclear circumstances. Currently works as a freight coordinator in the harbor district. Has not used his inscription work since leaving.
"Former Middle Sky," Rei said.
"Former third inscription," Wei said. "He stopped practicing when he came down. Which means he's been carrying a significant carving capacity for seven years and deliberately not using it." He looked at Rei. "You know what that costs."
Rei was quiet for a moment. "Yes," he said.
"Why did he leave?" Yan Ku asked.
"I don't know exactly. He doesn't talk about it." Wei turned his cup slowly in his hands. "But a man who walks away from the Middle Sky voluntarily and doesn't go back suggests either that something happened up there that he wanted distance from, or that he saw something he didn't want to be part of." He paused. "Either way, he has reasons."
Yan Ku nodded slowly. He looked at the third name, then the fourth. Both were people he filed away for later — possibilities, contingencies, names to return to if the first two didn't work out. The list was ordered by Wei's assessment of likelihood, which meant Maren and Dov were Wei's best guesses.
Best guesses from a man who had spent twenty years quietly paying attention were worth taking seriously.
"We approach them separately," Yan Ku said. "Not together. Two people arriving at once is pressure. One person arriving is a conversation."
"Agreed," Wei said.
"I'll take Dov," Yan Ku said. "The harbor district is familiar ground. I've worked cases there." He looked at Rei. "You take Maren."
Rei raised an eyebrow slightly. "Why me?"
"Because she's been mapping the underground passages for three years as a personal project driven by her own sense that something was wrong with the official record," Yan Ku said. "She already knows something is off. She just doesn't know what yet." He looked at Rei. "You're better at explaining the what than I am. You've been living inside this longer."
Rei considered this for a moment. Then nodded once.
"One condition," he said. "We don't tell them everything immediately. We give them enough to understand the situation is real and serious. We give them time to decide." He looked at Yan Ku steadily. "Isara gave me three days before she asked for my answer. I think that was right."
Yan Ku thought about how he would have felt three weeks ago if someone had sat down across from him and explained in full what the mark on his hand was, what it was designed for, what the network around it looked like. Whether three days would have been enough.
Probably not.
But three days was better than no days.
"Three days," he said.
He found Dov on a Wednesday afternoon at the harbor freight office — a long, low building on the waterfront where the practical business of moving goods in and out of Duskwall got organized and documented. Dov was at a desk near the back, working through a stack of cargo manifests with the methodical speed of someone who had been doing the same task long enough to do it without thinking.
He was a large man — broad through the shoulders, the kind of physical presence that the Middle Sky inscription work tended to create and that didn't entirely disappear even when you stopped practicing. Seven years of not using his carving and he still moved with the particular balance of a second-level practitioner. The body remembered what the mind had decided to forget.
Yan Ku sat down in the chair across from his desk.
Dov looked up. Registered an unfamiliar face. Did a brief assessment that was faster and more thorough than a civilian's would have been. Former Middle Sky habits, still present after seven years.
"Can I help you?" he said.
"I hope so," Yan Ku said. "My name is Yan Ku. I'm a district investigator — or I was, until recently. I need to talk to you about something that's going to sound unusual. I'd appreciate it if you heard me out before deciding what to do with it."
Dov looked at him for a moment. "What kind of unusual?"
"The kind that involves why you left the Middle Sky seven years ago."
The stack of cargo manifests became very still in Dov's hands.
The harbor freight office moved around them — other clerks, the sound of the waterfront coming through the walls, the ordinary machinery of commerce. Nobody was paying attention to the two men at the back desk.
Dov set the manifests down carefully. "Who sent you?"
"Nobody sent me," Yan Ku said. "I'm here because I need your help and because I think you might want to give it." He paused. "But I also think you deserve to know the full situation before you decide anything. So I'm going to tell you what I know, and then I'm going to leave, and I'm going to give you three days to think about it."
Dov studied him with the eyes of someone who had learned not to trust easily and had good reasons for that lesson.
"Talk," he said.
Yan Ku talked for twenty minutes.
Not everything — he gave Dov the shape of the situation without all the detail. The network. The chambers. What the network was designed to do and who had built it. The mark on his right hand and what it was. The interference marks and what they were designed to counter.
He did not mention Wei or Rei by name.
He did not mention the two remaining marks needed or ask directly for anything.
He just described what was happening, as accurately and completely as he could in twenty minutes, and watched Dov's face as he did it.
Dov's face did not change much. The face of a man who had already suspected something of this nature and was now having the shape of his suspicion confirmed rather than surprised by new information.
When Yan Ku finished, Dov was quiet for a long moment.
"The project," he said finally. "The restoration project, twenty years ago. I heard about it when I was still up there. There were rumors." He paused. "I didn't believe them. Or I didn't want to." He looked at his own hands. "Seven years ago I was asked to sign off on a series of property acquisitions in the lower districts. Routine administrative work. I looked at the acquisition pattern and — I recognized something in the structure. Something I had heard about in those old rumors." He paused again. "I refused to sign. I was told my concerns were noted. Two weeks later I was reassigned to a position with no administrative authority." He looked up at Yan Ku. "I left the week after."
"You understood what you were looking at," Yan Ku said.
"I understood enough." Dov's voice was flat. "Not the full picture. But enough to know I didn't want my name on it."
"And in seven years you haven't reported it. Haven't told anyone."
"Who would I tell?" Dov said. Not defensively. Just as a real question. "The Administrative Circle? Half of them are Casven's people. The district authorities? They have no jurisdiction over Middle Sky affairs." He looked at Yan Ku. "An investigator from the lower districts showed up at my desk today. That's the most promising option I've encountered in seven years."
Yan Ku almost said something.
Decided not to.
"Three days," he said instead, and stood up. "I'll come back on Saturday morning. You can tell me then whether you want to be part of this or not." He paused. "Either answer is acceptable. I'm not here to pressure you."
Dov looked at him steadily. "What happens if I say no?"
"Then I thank you for your time and find another way," Yan Ku said simply. "Your safety doesn't depend on your answer."
He left before Dov could respond.
Rei was already back when Yan Ku returned to Wei's building that evening.
He was sitting at the table eating something Wei had apparently provided, with the comfortable ease of someone who had adopted the space as his own without making a formal announcement about it. Wei was at the worktable reading. The room had settled into the particular atmosphere of people who were in the middle of something long and had found their respective positions within it.
"How did it go?" Yan Ku asked.
"She already knew something was wrong with the passages," Rei said. "She found a structural inconsistency eight months ago that she couldn't explain — the passage configuration near Renders Street didn't match any of the historical records she'd been able to find." He paused. "When I described the chamber she went very quiet for a long time."
"Quiet in which direction?"
Rei considered. "The direction of someone whose suspicion just found its evidence," he said. "Not frightened. More like — resolved."
Yan Ku nodded. He sat down and looked at the table.
Two conversations. Two people who had already been, in their different ways, circling the edges of the same thing. The cartographer who had been correcting the map because the inaccuracy bothered her. The former administrator who had walked away from the Middle Sky rather than put his name on something he recognized.
People who had already decided, in their own ways, that something was wrong.
Who just hadn't yet had anyone come and tell them what.
Wei was right, Yan Ku thought. Quality of attention. The ability to notice that something doesn't fit and to keep noticing instead of deciding you were probably wrong.
He looked at his right hand.
Two more marks. Two more people.
Two more days.
The timeline was shortening. He could feel it the way you felt weather changing — not visible yet, but present in the air. Casven's people had felt the mark open in the chamber. Casven's patience was a finite resource and it had been spending faster since Renders Street.
Move carefully, he told himself. But move.
"Wei," he said.
The old man looked up from his book.
"The third and fourth names on your list," Yan Ku said. "Tell me about them. In case Saturday doesn't go the way I'm hoping."
Wei closed his book and picked up his tea.
"The third name," he said, "is more complicated."
"How complicated?"
Wei looked at him over his cup.
"She currently works," he said carefully, "in Lord Casven's administrative office."
The room was quiet.
Rei stopped eating.
Yan Ku looked at Wei for a long moment.
"Tell me everything," he said.
Wei set down his tea.
And outside, above the clouds, the Middle Sky cities glowed with their permanent indifferent light — unaware, or perhaps simply unconcerned, that something was being built in the rooms below them that had not existed three weeks ago.
Something patient. Something careful.
Something that was just beginning to understand its own shape.
