They kept left.
Not drifting anymore, not making small corrections every few steps. Just holding a line and moving through it with the kind of consistency that came from having made a decision and not second-guessing it. The corridor looked the same as the stretch they had just come through, same tight walls, same uneven shutters, same quality of light that made everything feel slightly more exposed than it should. But their pace had changed. Whatever had been hesitant about the way they were moving before had settled into something more committed.
The corridor narrowed again after a short stretch, then opened slightly into a wider section that felt different from the parts they had already moved through. The storefronts here were bigger, but emptier. Less product filling the shelves, more open floor visible from the entrance. Like whatever this section had been built to represent, something had interrupted it partway through and left it in that state, half-assembled, the scaffolding of a space without the life that was supposed to fill it.
Caspian slowed, just slightly, his pace adjusting before he said anything. "This is different."
"Yeah," Naomi said.
Eli didn't answer right away. His hand brushed the ring under his shirt without thinking, the motion automatic, something in him checking without being asked to. It was warm. Not faint the way it had been earlier, not the low background warmth that had been easy to set aside and file under later. Noticeably warm, in a way that made him keep his hand there for a second before letting it drop. Whatever the ring was responding to had gotten closer, or more concentrated, or both.
He kept walking.
"Check that one," Eli said, nodding toward a wide unit on the right.
The entrance had no door. Just a wide opening with a partially removed frame, the fittings still visible on either side where something had been unbolted and taken out. Not broken off, unbolted, which meant it had been removed deliberately rather than damaged. Inside, the space stretched deeper than the others had. A few scattered display tables sat off to the sides, most of them bare, their surfaces clean and undisturbed. No shelves breaking the floor into lanes. No tight rows forcing a particular path through the interior.
Cleaner sightlines than any store they had checked so far. Wide and open and easy to see across. Which should have made it feel safer. It didn't. The openness of it changed the quality of the space in a direction Eli couldn't quite name, the feeling of being easy to see in both directions at once, of having the same visibility working against you that it was working for you.
Caspian stepped in first, slower than he usually moved, something in the space pulling his pace down without him deciding to.
Naomi stayed just outside for a second, scanning the full width of the room before committing to stepping through the entrance, using the angle from outside to check what the interior entry point would not show. It was the same thing she always did. By now Eli had stopped noticing when she did it and started noticing when there was a reason she didn't.
Eli followed in behind Caspian.
The space swallowed the hallway noise almost immediately. Not silent, just contained, the ambient sound of the building dropping off in a way that made the room feel set apart from everything around it, like the walls were holding something in rather than just marking a boundary.
Caspian's eyes moved across the room, methodical, front to back, left to right, then stopped.
"There," he said.
Eli followed his line of sight.
Someone was already inside.
Near the center of the room, slightly off to the left, another third-year stood with his back partially turned to them. Not tied. Not restrained. No signs of distress visible from this distance. Just standing there, weight settled, body language carrying none of the urgency they had seen from Caleb. Just waiting, the way someone waited when they had been doing it for a while and had made their peace with the duration.
He did not move when they entered. Did not turn right away, did not react to the sound of them coming in. Just stayed where he was, and let them come to the realization that he was there at their own pace.
Caspian glanced at Eli. "That's not what I expected."
"Same," Eli said.
Naomi stepped in now, closing enough distance to see the full picture clearly. Her eyes moved over the figure and then the room around him, reading both simultaneously, not committing to either one until she had enough of the other.
The third-year finally turned.
Lucius.
Eli recognized him immediately. He had seen enough of him around KMI to have a clear sense of how he occupied space, the particular quality of his stillness, the way he watched things without appearing to be watching them. That quality was still present now, even here, even in whatever version of this scenario he had been placed into. He was not panicked. Was not irritated. Was not reaching for anything from them or performing distress for their benefit.
He just looked at them, calm and measured, the expression of someone who had already accounted for their arrival before they stepped through the entrance and was simply waiting for the next part to begin.
"You're late," Lucius said.
Caspian blinked once. "Late?"
Lucius did not elaborate. "You're the last group."
Eli stepped a little closer, reading him the way he had been reading everything else in this building since they walked through the sealed doors. No restraints. No signs of struggle in how he was standing or in the space around him, no evidence in the floor or the tables nearby of someone having been there unwillingly. Nothing about this looked like what they had seen with Caleb earlier, the uneven breathing and the rushing words and the effort it had taken just to stay upright between two people holding him there.
"You good?" Caspian asked.
"I'm fine," Lucius said. That was it. No extra weight on it, no urgency underneath the words, no gratitude for being found. Just a flat statement of fact, delivered the way you delivered something that didn't require elaboration.
Naomi frowned slightly, her expression carrying the same question Eli was already working through. "You're not stuck here or anything?"
"No."
Caspian let out a quiet breath. "Alright, that's weird."
Eli looked between the three of them, then back at Lucius, holding the comparison in his head. Caleb earlier, talking too fast, barely holding himself together, genuinely needing the physical support of two people just to make it to the exit. The distress in him had been specific and real in a way that was hard to fake, the kind that showed in small things, the grip strength, the eye movement, the way breathing changed when someone was working hard to manage themselves under sustained pressure.
Lucius, now. Completely steady, not asking for anything, not performing distress of any kind, just waiting. Standing in a cleared store in the middle of a sealed training structure and presenting as though this were a meeting he had shown up to slightly early.
The same scenario. Two completely different versions of it.
"They're acting," Eli said.
Caspian looked at him. "What?"
"The hostages," Eli said. "They're playing roles."
Naomi nodded almost immediately, the pieces arriving for her at the same time they had arrived for him, the connection closing in the same breath. "Yeah. That makes sense."
Caspian ran a hand through his hair once, processing it, the motion quick and somewhat involuntary, the physical version of his mind catching up to the information. "So that guy earlier—"
"Caleb," Eli said.
"Yeah. Him. That was part of it."
Lucius did not react to the realization landing between them. Did not confirm it or deny it, did not shift his expression to acknowledge that they had gotten there, did not give them anything that would help them understand how close or far off they were. He just watched them, which was its own kind of answer, the kind that didn't give anything away and didn't need to.
Eli felt something in his chest settle slightly. Not relief exactly. More like the feeling of a question that had been taking up space finally resolving and leaving room for the next one. The distress had been scripted. That didn't make it irrelevant, it just meant the scenario was more constructed than it had appeared, which meant other things about it were also more constructed than they had appeared.
"Okay," Caspian said, already orienting toward the exit with the efficiency of someone who had processed the relevant information and was ready to move on it. "So we grab him and head back."
Naomi nodded. "Yeah. We know the path."
Eli turned slightly toward the entrance, already picturing the corridor they had come through, the route back to the main floor, the sequence of turns they had made to get here.
"Yeah," he said. "We go back the way we—"
He stopped.
The hallway outside was not the same.
The opening was still there, the frame still visible, the corridor still stretching forward beyond it. But the angle was wrong. Not dramatically, not in a way that was immediately obvious at a glance, but wrong in the specific way that things were wrong in this building, subtly, just past the edge of what you could dismiss without looking closer. The line of the wall on the right side did not match what he remembered walking through to get here. The geometry of the approach was off by just enough to put a different storefront in a position it had not been in before.
Naomi saw it at the same time. He could tell by the way her body language shifted, the slight change in how she was holding herself, weight redistributing in the way it did when something you had been counting on had turned out to be less reliable than you thought.
"That's not right," she said.
Naomi stepped up beside Eli and put her hand against the edge of the opening, compressing the frame for a second like she was trying to pin the geometry in place long enough to read it cleanly.
It held under her hand.
The hallway beyond it didn't.
Her expression tightened. "Yeah. That's wrong."
Caspian looked between them. "What do you mean?"
"That hallway didn't bend like that," Naomi said.
"It did," Caspian said, but there was less certainty in it than his tone suggested, the confidence sitting slightly in front of where his actual conviction was.
"No," Eli said. "It didn't."
They stepped closer to the entrance together, crossing the room with enough purpose that Lucius tracked them but didn't move, watching from the same position he had been standing in since they found him.
The corridor outside still stretched forward. But the storefront directly across from them was not the one that had been there when they came in. The shape of the entrance was different, the shuttering on it was wrong, positioned at a height that didn't match what they had passed, and there was no version of the path they had taken that put that store in that position. Eli stood in the entrance to the wider unit and looked at it directly and let himself be certain rather than hedging toward the more comfortable interpretation.
"That's different," he said.
Caspian stared at it for a moment, the frown deepening as he gave it genuine attention rather than a quick dismissal. "We might've just come in from a different angle."
"No," Eli said. "We didn't."
Naomi nodded. "We didn't pass that store."
Caspian exhaled sharply through his nose. "So what, it moved?"
No one answered that, because none of them had an answer that felt adequate to what they were looking at, and saying something inadequate felt worse than the silence. The corridor had changed. The building had rearranged something about itself while they were inside one of its rooms. That was the fact sitting in front of all of them, and the fact didn't become less true just because none of them had a framework for it yet.
Eli pressed his thumb against the ring through the fabric of his shirt. Warmer than before, the warmth more concentrated now, less like ambient heat distributed across a space and more like something with a specific source in a specific direction. The direction it was pointing was not toward the corridor outside.
"It's worse," he said. "Whatever this is, it's worse than it was when we came in."
Lucius stepped forward for the first time, a single deliberate pace. Not toward the hallway and not toward the entrance. Toward the center of the room, and specifically toward the back of it, his attention moving past them toward a point that Eli had not fully registered when they first came in, his eyes settling on something beyond the angle their entry had given them.
Eli noticed it immediately. "Why are you moving that way?"
Lucius did not answer right away. He kept looking at whatever he was looking at, giving it his full attention without redirecting it toward the question.
Eli turned.
There was another section they had not seen clearly when they entered. A smaller opening, set deeper into the unit, the entrance to it partially obscured by the angle they had come in from. Not hidden. Not sealed. Just not visible from the doorway, the kind of thing you would only find if you went far enough inside to change your line of sight, if you had a reason to keep moving rather than stopping where you were.
Caspian frowned. "That wasn't—"
"It was there," Naomi said, but her tone carried the uncertainty she was not quite saying out loud, the awareness that she could have missed it as easily as any of them.
Eli did not argue either way. He pressed his thumb against the ring again, holding it there rather than letting his hand drop. The warmth was stronger now, more specific, with a direction to it that pointed toward that opening rather than anywhere else in the room. Not a vague warmth distributed evenly across his chest. Something targeted. Something that had been building toward this point since they entered the building and had finally found what it was pointing at.
"Something's back there," he said.
Caspian looked at him. "You sure?"
"No," Eli said. "But it's there."
That was enough. Caspian nodded, the uncertainty accepted and set aside, the decision made. "Then we check it."
Naomi hesitated for a half second, something running through her expression that she didn't put into words, some calculation completing itself behind her eyes. Then she followed, the hesitation brief enough that it didn't change anything.
Lucius was already moving.
Not ahead of them, not leading. Just moving at the same time, in the same direction, like he had already known this was where they were going and had been waiting for them to arrive at the same conclusion.
They pushed deeper into the space, the display tables falling away behind them as the room narrowed toward the back section. The lighting shifted slightly as they went, not dimmer in any way that could be measured, just flatter somehow, the overhead light doing the same work but the room receiving it differently, the quality of it changing in a way that made the shadows sit heavier without there being more of them.
Eli's hand stayed against the ring. The warmth had moved past the level he associated with background awareness, pressing now toward something that demanded attention rather than just registering as present.
"Something's wrong," Naomi said quietly, her voice carrying just far enough to reach him without carrying any further.
"Yeah," Eli said. He didn't say anything else. The word was enough.
They stepped through the opening.
The space beyond it was not a store. It had none of the features of the other units they had moved through, no displays, no shelves, no remnants of whatever purpose it had been built to serve. Just a wide, open room with bare walls and a floor that looked like it had been swept clean at some point and not touched since, the surface of it holding nothing except the light from above and the four of them.
And in the center of it, a wooden hourglass.
Old, the kind of old that was specific rather than general, not just worn from age but worn from use, the frame dark and smooth at the edges in the way that came from years of hands handling it, lifting it and turning it and setting it back down. It sat on a low stand as though it had been placed there deliberately and carefully, positioned in the exact center of the space with a precision that did not happen by accident, the kind of placement that required someone to stand back and check rather than just set it down and walk away.
The sand inside was moving.
But not the way sand was supposed to move.
Some of it fell, dropping through the narrow passage the way it should, following the direction gravity was supposed to give it. But some of it rose at the same time, climbing back up against the direction it should have been falling, both things happening simultaneously in the same glass, in the same chamber, without any apparent mechanism or explanation.
It wasn't stuttering. It wasn't glitching or looping. It was just doing two things at once that should have been mutually exclusive, running both directions simultaneously and not resolving either one into the other.
Eli stopped walking.
His hand pressed hard against the ring through his shirt, the heat of it sharp enough now that he registered it as a distinct sensation separate from everything else, the way you registered something when your body had stopped trying to contextualize it and was just reporting it plainly.
He flicked his hand toward a loose bit of grit near the threshold.
It should have skipped forward across the floor.
Instead, the movement cut short halfway there and dragged off at the wrong angle, like the force he put into it had been taken and bent somewhere else.
He stared at it for a second, then looked back at the hourglass.
"Okay," Caspian said, his voice slower than usual, the words coming out carefully, measured in a way that was different from his usual pace. "That's a pretty weird thing to leave here."
Naomi did not say anything. Her eyes were fixed on the hourglass, tracking the sand moving in both directions at once, her expression doing the work of processing something that did not fit the categories she had available for it, the particular quality of someone encountering information that is both clearly real and clearly not possible and having to hold both of those things at the same time.
Lucius stepped forward one more deliberate pace, then stopped. Like he had reached the point he intended to reach and was done moving, the destination having arrived.
Eli looked at the hourglass again. The sand shifted, both directions at once, the motion continuous and steady, not struggling against itself, just doing what it was doing, whatever that was.
He could feel the space now in a way he had not been able to before, or had been feeling in pieces that were only now assembling into something coherent. The same pressure that had been building since they first walked through the sealed doors at the entrance, the thing he had been describing to himself as the space reacting, was concentrated here. Not ambient anymore, not spread out across the hallways and storefronts and shifting shutters like a low signal distributed through a building. Focused. Sitting in this room and on what was in the center of it, gathered the way weight gathered at the lowest point of something.
"This is it," Eli said. "This is what's been changing everything."
No one argued with that. No one moved to correct it or offered a competing explanation. The three of them stood there holding the same understanding from different angles, and the silence that followed was not the silence of people unsure what to think. It was the silence of people who had arrived somewhere they had been moving toward without knowing it, and had not yet decided what to do about being there.
Caspian spoke first, his voice carrying less of its usual forward momentum, something in the situation having slowed him down in a way most things didn't. "So what do we do with it?"
Naomi shook her head once. "I don't know."
They looked at Eli.
He was still looking at the hourglass. The sand moved in both directions, patient and continuous, indifferent to the four of them standing around it. The ring was burning steadily against his chest, not spiking the way it did when something was immediately threatening, not the sharp escalating heat of danger arriving. Just burning, steady and specific, like it was in direct contact with whatever was producing this and had been since they walked through the door.
He stood there looking at it, and the building waited around him, and the sand kept moving in both directions at once, and somewhere above them or ahead of them the other groups were dealing with their own versions of this or were already back at the entrance or had already found what they were looking for and returned it, and none of that information changed what was in front of him right now.
He took a breath.
"We figure it out," he said.
The hourglass didn't respond. The sand kept moving, both ways, unhurried and continuous, the way something moved when it had been doing it for a long time and had no particular reason to stop.
