The first guard reached the service track before Cage Seven reached the landing.
He came down a narrow stair beside the archive and stepped onto the track with a signal baton in one hand. Another guard followed him carrying a short shield. Neither had a clear path to the cage yet; the track curved behind a row of braces, and the carriage moved on the outer side of them.
“Stop the cage,” the first guard shouted.
Tavin kept one hand on the control lever. “You’re welcome to come down to the landing and ask.”
“Stop it now.”
“If I stop it here, we hang over a gap.”
The guard looked at the gap, then at the control line. He struck the rail with the baton. A signal sounded farther along the track.
Kesh answered from the near deck with her lamp: two quick flashes, then one long. A second cage crew had been alerted. Iven could see workers moving at the landing, clearing carts from the track.
“Will they block us?” he asked.
“They’ll be told to,” Tavin said. “Whether they do is another question.”
Elian held the copied ledger pages inside his coat. Neri kept one hand on the cage rail and watched the support frame. Iven seated plate brace, spring step, and hook cast. The new pattern felt less familiar than the others. He had practiced it only once after repairing the launcher. He did not want his first combat use to depend on a perfect cast.
The guard with the shield reached a control box beside the track. He opened it and pulled a lever.
The cage slowed.
Tavin swore and shifted his own lever. “He’s applied the service brake.”
“Can you release it?” Neri asked.
“From the landing. Or from that box.”
The cage stopped with the near deck still several lengths away. The gap below was not deep enough to be reassuring. A fall would end on pipes, braces, or the hard ground beyond them.
The first guard approached along the narrow track. “Surveyor Veyr, the archive requires the copied material returned pending review.”
Elian stepped forward. “My authorization permits copying.”
“Your companions entered a restricted gallery.”
“Yes. They did not remove a volume.”
“The review will determine what they removed.”
Neri held up her empty hands. “We left the gallery in better condition than we found it.”
The guard did not look impressed. “Return the pages.”
Elian kept his hand inside his coat. “Show me the order.”
The guard reached for a folded paper. Iven watched his other hand. The baton remained angled toward the cage’s control line, close enough to strike it.
“Don’t touch that,” Tavin said.
The guard unfolded the paper. It bore a security seal and instructed the crew to hold the surveyor and his companions until the archive’s material had been accounted for. It did not specifically revoke Elian’s copying authorization. Iven was not certain that distinction would matter to a guard standing over a suspended cage.
“Bring us to the landing,” Elian said. “I’ll speak to the archive officer there.”
“You’ll speak from here.”
A second signal sounded from the landing. Kesh’s lamp flashed again. This time the pattern was different: movement on the near deck.
Iven saw two guards crossing behind the carts. One carried a bow-like launcher fitted with a short line. They were preparing to secure the cage from the landing side.
“They’ll tie us in place,” he said quietly.
Neri looked at the track. “Can you reach the control box?”
“Not from here.”
“Can you reach the brace beside it?”
He measured the distance. It was within the ordinary reach of hook cast, but the brace sat behind the guard with the shield. A tether could steady him across the gap; it would not make the guard disappear.
Tavin lowered his voice. “If you get to the box, release the brake halfway. The cage will move toward the landing slowly. Don’t throw it open.”
“Why halfway?”
“Because the track curves, and I’d like the cage to stay on it.”
“Good reason.”
Iven stepped to the opposite side of the cage. The first guard saw him move and raised the baton.
“Stay where you are.”
“We’re trying to get to the landing,” Iven said. “You can come with us.”
The guard took a step forward. The man at the control box lowered his shield and put his hand on a short bar at his belt. Iven could see a pale graft line at the base of his neck. He was a restorer, though Iven could not tell his rank from the line alone.
Iven cast the tether toward the brace beside the control box. It crossed the gap and caught. The guard with the shield struck at it. The compact line shivered under the blow but held long enough for Iven to spring from the cage’s side rail to the track.
His boots landed on the narrow metal strip. He kept one hand on the tether and his weight low. The shield guard came at him immediately, bar raised.
Iven formed a compact plate brace against his forearm. The bar hit it with a hard crack. He turned the force toward the rail and stepped inside the guard’s reach. The guard brought the shield across, trying to pin Iven against the brace.
Iven released the tether. It vanished from his active grip, freeing his hand. He struck the shield’s edge with his hammer, not to break it, but to move it away from the control box. The guard held firm.
Behind them, the first guard shouted for him to stop. Iven heard the baton strike the cage rail. Tavin shouted back, angry now rather than amused.
The shield guard pushed. Iven gave ground for one step, then used spring step to move sideways onto a wider service plate. The impulse was short and controlled; a longer leap would have put him over the edge. He landed beside the control box.
The guard swung the bar. Iven caught the blow on his brace and drove his shoulder into the shield. The impact moved the guard half a step. It also moved Iven half a step in the opposite direction. He had learned not to expect a force to act on only one person.
He reached for the brake lever. The guard hooked the bar behind his wrist and pulled it away.
“Don’t,” the man said.
“Then open it yourself.”
“I have orders.”
“So do I. Mine are from the person who knows how the cage works.”
The guard’s mouth tightened. He struck again. Iven blocked, then let the brace collapse and reseated piston strike. The change took several heartbeats. He used them to move around the box, keeping it between them. The guard followed, shield high.
A line snapped across the track from the landing. It caught the cage’s outer rail and tightened. The workers below shouted. Kesh’s lamp flashed urgently.
The cage tilted a few degrees toward the landing. Tavin held the control lever steady, but the line was pulling against the service brake.
“Halfway!” he shouted.
Iven had no time for another circuit around the box. He stepped toward the guard as if he meant to strike the shield. When the shield rose, he drove a piston impulse into the box’s metal handle, not the guard. The handle moved just enough to free the brake lever.
He caught the lever with his right hand and pulled it to the mark Tavin had shown him. The cage began moving. The line from the landing went slack, then tightened again as the crew reeled it in.
The shield guard grabbed Iven’s coat. Iven turned, caught the man’s wrist, and used the guard’s forward motion to put him against the control box. A compact brace held the shield away from Iven’s chest. He did not strike the man’s head against the metal.
“It’s moving,” he said. “You can stop fighting me.”
The guard looked toward the cage. Tavin had control. The carriage was advancing slowly, and the landing crew were guiding it rather than trying to haul it off the track.
The guard released Iven’s coat. “You’ll answer for this.”
“Probably.”
Iven stepped back. The first guard had followed the cage as far as the next brace. He stood with his baton lowered, watching the landing. He did not attack as Iven passed him.
At the near deck, Kesh and two workers caught the cage and secured it. Neri climbed out first, then Elian. Tavin locked the carriage before leaving the controls. Iven crossed the final short gap using the ordinary service rail rather than spending more charge on the hook.
The landing guards approached. Elian produced his authorization and the copied pages. He did not surrender the pages. He showed the guards the headings, the entry dates, and the archive clerk’s consultation mark.
“You can accompany me to the survey office,” he said. “The archive can send an officer there.”
The guard with the launcher looked at the paper, then at the workers gathered around the cage. “We were told to hold you.”
“You’ve held us. Now the cage needs to return to passenger service.”
Tavin stood beside the gate. “I’ve got people waiting at the lower landing. One is being carried on a stretcher. If you want the cage kept here, put your name on the instruction.”
The guard looked down the track. He did not have a written order to delay a medical transfer. He stepped aside.
Iven admired Tavin’s ability to make a question about procedure sound like a threat without raising his voice. He suspected years of moving people through narrow spaces had taught the captain which words carried the most weight.
They went to the survey office with one guard accompanying them. The archive officer arrived an hour later, examined the authorization, and demanded a copy of Elian’s notes. Elian provided one under receipt. He retained the original pages. The officer objected to the entry into the gallery but did not have grounds to seize notes from equipment labels visible to a maintenance worker.
By the time they left, the day was already turning toward evening.
Sera met them outside with Brell and Vela. She did not ask about the guards. She took one look at Iven’s torn sleeve and asked, “Did you get the number?”
“And the ledger entries,” Elian said.
He spread the pages on a bench. Sera read the phrases suppression adjustment and tissue draw, then compared the equipment number with Brell’s mounting record. Vela checked the pressure reading Iven had copied from the gallery.
“That pressure is above the ordinary service range,” she said.
“Harl requested a pause,” Iven replied. “The upper room didn’t answer in time. We tightened the guide bolt.”
Vela’s face went still. “The upper room should have answered.”
“Can you contact them?”
“I can try.”
Sera followed the ledger references with one finger. “These adjustments occur before the wall movement increased. I can’t prove they’re causing it, but the timing is close enough that the regulator needs inspection.”
“Halwen?” Iven asked.
“She confirmed living fibers in both samples. She won’t release the full report yet. She did say the tissue was under stress.”
Brell looked toward the heat-line stair. “If the regulator fails, what happens to my chamber?”
“I don’t know,” Sera said. “The damaged tissue may be connected to the system below. The pressure and movement could change quickly.”
“What do you need?”
“People warned. Routes kept clear. The upper control room told that the guide was loose and the pressure was high.”
Vela took the copied pressure reading. “I’ll go.”
“I’ll come,” Brell said.
Neri gathered her tool roll. “I’ll check the supports above the line. If the wall moves again, I want my crew out before it takes the frame with it.”
Tavin had already turned toward Cage Seven. “I’ll tell the local transfer crews to keep a cage free.”
Elian looked at the notes. “I’ll take these to the survey office and ask for a direct inspection order.”
Sera folded the pages carefully. “I’ll keep a copy.”
Iven listened to each decision. None depended on him giving an order. The people around him had work they understood and reasons to act. His own task was to make sure the warning reached the places where a voice and a sheet of paper might not travel quickly enough.
He went with Neri to the heat-line junction. Brell’s crew had posted the restricted notice beside their own time sheet. The two papers looked awkward together: one telling workers not to discuss unverified reports, the other listing the exact times a creature had appeared near the damaged mounting.
Neri’s crew moved tools away from the wall and checked the route to the stair. Iven inspected the movable support. The padded blocks had shifted. He loosened one bolt, moved the block outward, and tightened it again. The wall pressed against it almost immediately.
“That’s more than yesterday,” he said.
Dessa looked at the pencil marks. “How much more?”
“Enough that I don’t want anyone working between the plate and the pipe.”
They marked a boundary on the floor and moved the tool rack. Iven used bell resonance once, a short pulse directed through the iron rail to signal the crew farther down the passage. It was not the immense warning he had sent during the Lower Return failure. It was enough to make the rail ring under their hands.
The workers came to the junction. Neri explained the pressure warning and showed them the clear route. One man asked whether the city was about to fall apart. She told him what she knew: the wall was moving more, the regulator pressure was high, and the crew should leave if Brell’s whistle sounded. She did not tell him that everything would be fine.
The pipe gave a low knock.
Brell and Vela returned from the upper room. Vela’s face was pale beneath the dust on her cheeks.
“They’ve agreed to inspect the regulator,” she said. “Tomorrow morning.”
“Tomorrow?” Sera asked.
“The control room says the pressure remains within the emergency range.”
“Not the ordinary range.”
“No.”
Brell held up the brass key to the branch valve. “I’m keeping the reduction.”
Vela nodded. “I’ll support it.”
A deeper sound traveled through the wall. It was not a knock from the pipe. Iven felt it in the soles of his boots, a slow pressure followed by a release. The movable support shifted against its padded blocks.
Everyone in the junction looked toward the chamber door.
The wall moved again.
