I didn't sleep.
I had told myself I would — an hour at least, enough to let the palace settle into its nighttime rhythms before I moved — but I lay on the narrow bed with my eyes open and my notebook on my chest and listened to the building breathe instead. Stone carried sound differently than concrete. This particular stone carried it with the specific quality of a place that was trying to seem quieter than it was: distant footsteps that stopped too abruptly, a door somewhere below that closed with the careful slowness of someone who didn't want to be heard closing it, and once, around what I estimated was the third hour of the night, a bell from the cathedral wing that rang twice and then stopped mid-toll as if someone had changed their mind about announcing something.
I noted all of it.
By the time the sky outside my window had shifted from black to the particular dark grey that preceded everything else, I had seven anchor points mapped in the notebook, three working theories about the door at the end of the corridor, and a list of twelve questions I intended to have answered before the seventh bell.
I got up. The stone floor was cold through my socks in a way that the palace's wool rugs didn't fully address, and the air in the room had the chill of somewhere that heated slowly and lost it quickly. I washed my face with water from the basin — cold enough to be unpleasant, which was the point — and looked at my reflection.
The steel mirror looked back. Slightly distorted, slightly rippled, the way polished metal always was.
Anchor one, the system noted, quietly in the corner of my vision.
I dried my face and went to find the others.
The corridor was grey and silent at that hour, the oil lamps burning low, most of the palace still horizontal. I moved through it slowly — hands in pockets, slight drag in the step, the body language of someone who had woken too early and had nowhere particular to be. It was a posture I had practiced. In volume 203 of The Unremarkable Man, the entire premise rested on the idea that most surveillance, human or magical, filtered for purpose — move like you have somewhere to be and you get tracked, move like you're doing nothing and you become furniture.
I stopped in front of the ceremonial breastplate between the two tapestries.
Up close it smelled of metal polish and old fabric, and the surface was better than I had estimated from a distance — deep enough to catch a clear reflection, stable, permanently fixed. I reached out and placed two fingers against the cold metal, felt the faint resistance of the anchor registering, and pulled my hand back.
Anchor two.
The window at the far end caught the early light at the angle I had calculated. I didn't stop — just let my fingers brush the glass as I passed, casual, a man trailing his hand along a wall out of habit.
Anchor three.
That left the door.
I had been thinking about it since the second hour of the night, and standing in front of it now in the grey pre-dawn quiet, it was more interesting than it had looked from a distance. The stone around the frame was older than the rest of the corridor — different color, slightly rougher, the kind of mismatch that happened when something had been sealed and then reopened and the original material wasn't available to match exactly. The lock mechanism on the outside was standard palace issue. But on the inside edge of the frame, barely visible unless you were looking for it at the right angle in the right light, a thin line of a different material had been set into the stone. Pale, almost translucent, catching the low lamp in a way that regular mortar didn't.
I crouched to look at it more closely.
In volume 612 of The Sealed Chambers of Errath — not a great novel, overlong and repetitive in the middle third, but extraordinarily useful for its treatment of arcane security — the protagonist had touched exactly this kind of boundary line on exactly this kind of door. He had spent the next four chapters dealing with the consequences, two of which involved significant structural damage to his own nervous system.
I stood back up.
The frustrating thing was that I couldn't mark a reflection from this side. The door was solid, no surface, no gap underneath wide enough to be useful. Whatever was in there — and something was in there, something important enough to seal and then pretend didn't exist — I couldn't see it yet.
Yet.
I put my hands in my pockets and walked to the staircase, feeling the particular dissatisfaction of an obstacle that wasn't ready to move. Some doors required different keys. I just didn't have this one's key yet, and not having a key I needed was the kind of thing that would sit in the back of my head until it resolved itself, which was — I had come to understand about myself — both my most useful quality and my most exhausting one.
I noted it under the door entry in my notebook and went downstairs.
The training courtyard was a wide stone square behind the east wing, open to the morning sky, torches still burning on the walls in the grey light. Three of the others were already there.
Dawon was running the perimeter. Not the casual jog of someone warming up — the focused deliberate pace she used when she was processing something, arms tight, glasses gone. She had done the same thing the night her mother called to announce the remarriage, excusing herself from dinner while I watched from the kitchen window as she ran six laps of the apartment complex in the rain, and I had understood then that this was how she handled things that didn't fit into the frameworks she had built for them. The frameworks were load-bearing. When something threatened them she ran until she had rebuilt the structure around the new information.
She didn't acknowledge me when I arrived. That was fine.
Areum was seated on a low stone bench near the eastern wall, knees together, hands folded, eyes on the middle distance. She looked like someone waiting for a bus — completely still, completely present, registering everything without appearing to register anything. A guard twenty meters away was half-asleep against the wall at the end of a long shift, and I watched Areum watch him with the patient thoroughness of someone taking inventory of a room before she decided how to use it.
She glanced at me when I sat beside her.
"You didn't sleep," she said.
"Neither did you."
"I need less than most people." A pause, during which a bird crossed the courtyard and she tracked it without moving her head. "You were in the corridor at the second hour. You stopped at the door at the end for forty seconds."
Forty-three. I didn't correct her.
"Curious about the architecture," I said.
"Yes," she agreed, with the specific tone that meant she had filed the information and closed the folder and we were done with the subject, for now, on her terms rather than mine. She looked back at the middle distance.
That was the thing about Areum. She never pushed. She simply kept everything, and you were never entirely sure what she was doing with it.
The silence between us settled into something comfortable enough — she was not a person who felt the need to fill it, which I appreciated — and I watched Dawon run and thought about the door and the bell that had stopped mid-toll and the way the younger priest's hand had pressed one beat too long against my skull.
And then, because the thought was apparently waiting for a quiet moment to surface, I thought about Jiyeon in the corridor. Silk and lamplight and the way the glow had come from below. Don't get killed, whatever you are.
I looked at the courtyard wall.
Filed it. Closed the folder. Moved on.
Haerin arrived at a run.
Not the processing run Dawon was doing — the run of someone who had woken up, remembered where she was, and decided that this was, on balance, interesting. She had her hair up already and was eating a piece of bread in transit, cheeks flushed with something between cold air and enthusiasm.
"There are horses," she announced, dropping onto the bench on my other side and leaning across me to look at Areum. "Real ones. A whole stable. One let me pet it for almost a minute before the groom noticed and came over looking panicked."
"Before or after you acquired that bread?" I asked.
"I didn't steal it. A kitchen boy gave it to me." She considered this. "He was very eager to give it to me. Is that a cultural thing here, giving people bread?"
"You have that effect on people," I said. "And apparently horses."
She grinned and bit the bread and looked up at the pale morning sky with the expression of someone who had decided, in the absence of any better option, to find this genuinely interesting. It was not a performed reaction — I had watched Haerin across six months of dinners and hallway collisions and I knew the difference between her cheerfulness and her actual cheerfulness, and this was the actual kind. She was eighteen and she had been ripped out of her world overnight and she had decided to meet it with the same attention she brought to every creature she had ever encountered — openly, without armor, at whatever risk that involved.
I thought about the donjon briefings Jiyeon had mentioned. The incursion statistics. I thought about what met people without armor in a world at war.
I ate some of her bread without asking. She didn't object.
Dawon finished her lap and stopped at the edge of the courtyard, breathing controlled, and looked at the three of us on the bench with her arms crossed and her glasses back on. The expression she was wearing was one I had seen before across dinner tables and shared corridors — the expression of an engineer who had an anomalous result and had given herself permission to address it directly.
"B rank," she said, looking at me.
"Good morning," I said.
"We covered good morning. We didn't cover the part where the evaluation crystal read four people accurately and returned an error on the fifth." She sat on the bench on the other side of Areum, which put the three of them in a row facing me, an arrangement that had the unintentional geometry of a tribunal. "I know what a measuring instrument looks like when it can't complete a reading. I've worked with sensors that returned null values. That's what happened with you."
Haerin had stopped chewing.
Areum was doing the three-second look — slow, thorough, the scan she used when she was deciding how to file something.
The courtyard was very quiet. The guard against the wall had fallen fully asleep. The torches made small sounds in the morning air.
"The crystal said B," I said.
"The crystal said B and unclassified," Dawon said. "Those are two different statements. B is a result. Unclassified is a system telling you it doesn't know what it just measured."
She was, as she usually was, entirely correct.
I looked at her. She looked back with the focused patience of someone who had built a case and was waiting for the other party to acknowledge the foundation before proceeding to the structure.
"I'll keep doing my best," I said.
A long pause.
Something moved across her face — not quite frustration, not quite something else, the expression of a person recalibrating around a variable that had declined to cooperate. She uncrossed and re-crossed her arms.
"Fine," she said. "For now." She stood and began stretching her hamstrings with precise attention, which was how she closed conversations she intended to reopen later on her own terms.
For now meant she had set a deadline I hadn't been given the specific terms of. I noted it and made a mental note to get ahead of it.
Seoyeon arrived from the direction of the palace interior rather than the residential wing.
This meant she had been awake and elsewhere since before dawn, which was not surprising — she was the kind of person who located the nearest medical supplies within hours of arriving anywhere new, out of the same reflex that made her always carry a small kit in her bag and always know where the exits were. She was carrying a small leather case that was clearly the palace equivalent of what she kept in that bag, which confirmed she had found the medical stores, or had been given access to them, or had simply gone to find them in the grey pre-dawn hours without asking anyone's permission.
Knowing Seoyeon, the last one.
She sat beside me on the bench without preamble, set the case on her knee, and looked at my right hand.
"Hand," she said.
"It's fine."
"I told you I'd check it in the morning."
"It's barely morning."
"Hand, Siwon."
She said it with the specific patience of someone who had learned not to ask twice in emergency rooms and had brought that economy home. I gave her my hand.
She examined the cut with the concentrated attention she brought to everything clinical — not cold, not mechanical, but focused the way a craftsperson was focused on their own work, the way she got focused on anything she had decided mattered. Her thumb moved along the healed line, reading the tissue the way she read everything, and then she went still.
"It's healed," she said. Not quite to me.
"Told you."
"It's healed completely. Since last night." She turned my hand over, looked at the palm, turned it back. Her expression was doing something careful and precise behind its surface. "That's not a normal rate. For anyone. Let alone—"
She stopped.
"For a B rank," I finished.
She looked up at me.
Up close, in the early morning light, there was something unguarded in her face that the controlled expression hadn't fully covered — not alarm, not the yandere attentiveness I had learned to read in the months of living with her, but something quieter than either of those things. The look of a doctor encountering something that didn't fit her model and finding that more interesting than troubling.
"Much faster," she said, quietly. "For any rank."
Behind us, I heard Haerin make a small interested sound. Dawon's stretch paused by half a second. Areum did not react, which meant she had already noted it and filed it before Seoyeon finished speaking.
"Good news then," I said.
Seoyeon looked at me for a moment longer. Her thumb moved once more across the healed line — the ghost of a clinical gesture, or something else entirely, I had stopped being sure which was which with her — and then she released my hand and closed the case and looked at the courtyard.
"Good news," she repeated, in the tone that meant she was leaving something unsaid and had decided to leave it unsaid deliberately, which was different from not having anything to say.
Her hand rested on the bench between us. Not touching mine. Half a centimeter away, maybe less, in the specific way that people who were aware of distance were aware of it.
I looked at the courtyard wall.
I ran Mirror Step drills in the far corner while the others trained.
Short hops, nothing that read as unusual from a distance — just a person moving erratically across a training yard, the kind of footwork that looked like agility training to anyone who wasn't specifically watching for teleportation. I was learning the system's textures: the warmth of an anchor point already registered, the slightly rougher quality of the cooldown fading back to smooth, the way the space around each anchor had a weight to it now, a familiarity, like rooms I had been in long enough to navigate in the dark.
Step. The breastplate anchor, the corridor seen for a fraction of a second.
Step back. The mirror in my room, grey morning light.
Step. The window.
I was building something. A web with eight points in it so far — nine, if the courtyard torch bracket held the angle I thought it did. Not enough yet. Nowhere near enough. But somewhere to start.
I stopped when I noticed Seoyeon had crossed to the far side of the courtyard.
She was standing still, watching me, with her arms at her sides rather than crossed — she crossed her arms when she was processing from a professional distance, kept them down when something had gotten past the professional distance before she could close it. She was twenty meters away and her expression was doing something I didn't have a clean word for yet.
"That was three points," she said, when I walked over. "In under two seconds."
She hadn't moved toward me. But her eyes had, for a brief moment before she controlled it, flicked to the point where I had disappeared and reappeared with the involuntary focus of someone tracking something that had moved faster than expected. A flinch that wasn't a flinch. A tell she had already closed down by the time I reached her.
"Footwork drill," I said. "Volume 1,847. The Spatial Monk of Verenthis. Long series."
She looked at me.
"Volume 1,847," she said.
"I read a lot."
A pause. The controlled expression was back — professional, precise, giving nothing. But it had arrived a half-second after it should have, and we both knew it, and neither of us mentioned it.
"Breakfast," she said. "You haven't eaten."
"In a minute."
She turned back toward the palace, and then stopped, and said without turning around: "Whatever you're building — be careful with it."
I watched her walk away.
Not be careful, Siwon. Not be careful with yourself. Whatever you're building. She had seen the pattern. She had named it accurately in six words and then walked away and left me with it.
I stood in the courtyard in the early morning light with the web of anchors faintly warm in the edges of my vision, and I thought about Seoyeon's hand on the bench at half a centimeter, and the door I couldn't open yet, and the bell that had stopped in the night, and I went inside.
