Chapter 83: Three Cuts

Rafael finished the third severance mark across the mineral skin and stepped back from the wall.

The three chalk slashes sat several feet apart along the white line Leo had drawn during the mapping work. A hammer, two chisels, a short steel saw, iron wedges, and a canvas sack of broken stone lay on a board beside them.

Carrick and Ruth waited back toward the settlement, outside the work zone, with bandages and splints ready.

Leo looked down the route behind them. "Exit?"

"Clear," Armin said.

"The shelf?"

"Same as last check," Rafael said, glancing at the field book.

Leo nodded. "Same rules. If anything outside this section reacts, if the shelf changes, or if the way out starts closing, we leave. No arguments."

Severin pulled off his right glove. "You say that like we enjoy arguing."

Leo gave him a flat look. "You do."

"Fair."

Leo pointed to the first mark. "Open it."

Rafael set the field book aside and took the hammer while Leo worked the chisel. They removed the mineral shell in small pieces, stopping as soon as the pale branching beneath it showed through.

The conduit was broader than the shadow beneath the shell had made it look, flattened into the surrounding material like a tendon caught under stone.

Leo uncovered his marked left hand and pressed it against the wall beyond the cut point. The green mark brightened while he waited through the returning vibration.

"Baseline’s holding. Suppress it."

Severin crouched and placed his bare right palm against the exposed conduit. A faint green glow pressed through the covering over his blind left eye as he drew heat from the pale tissue without letting the cold spread into the whole wall. Moisture darkened around his fingers but never whitened.

"Enough," Leo said.

Severin held the pull steady. Leo tested again, then reached for the saw. "Hold it."

The teeth bit slowly at first. Pale tissue compressed under the blade, tougher than flesh and softer than mineral. Severin kept drawing heat while Leo sawed through, shifted several inches along the conduit, and made the second cut.

Leo worked the short section free and set it aside. Both exposed ends recoiled into the opened casing.

"Hold them."

Leo crushed and split the lower end with the chisel, then cracked the upper. Rafael drove one wedge beside it. They packed broken stone into the missing span and hammered the second wedge tight before Severin released the pull.

Neither end crossed the gap.

Leo moved to the downstream contact and set his marked palm against it. He sent a low pulse through the structure, waited, and repeated it. "No return."

Rafael picked up the field book. Leo tested again after several seconds.

"Still none."

The first cut was over quickly. Severin looked at the packed gap. "That went suspiciously well."

"Don’t ruin it," Leo said.

Rafael pulled off his right glove as they moved to the second mark. Leo checked both remaining routes before anyone touched the casing, his fingers shifting against the wall after each reading.

"Stronger."

Rafael looked up. "Both?"

"Both."

"Before the cut?"

"Yes."

Rafael wrote it down. "Compensation?"

"Working assumption."

The question mark stayed on the page.

They opened the second casing. The moment Severin started pulling heat, he felt the difference. Warmth returned through the conduit almost as quickly as he removed it.

He increased the extraction until the pale tissue dulled under his palm, only for heat to creep back from deeper inside the wall.

"Still active," Leo said from the monitoring point.

"I noticed."

Severin drew harder. He shifted his left boot deliberately on the wet stone. The movement came when he wanted it this time, but he noted it anyway.

"Now?"

Leo pulsed the wall again. "Suppressed. Keep it there."

Leo set the saw into the tissue and made the first cut. Halfway through the second, the conduit flexed beneath Severin’s hand.

"Leo."

"I feel it."

The final teeth tore through. The severed tissue contracted hard enough to crack the opened casing from end to end, and a mineral plate beside Rafael broke loose with a sound like a paving stone dropped on a cellar floor. It slid across the wet rock toward Leo’s legs.

Rafael lunged and planted his marked right hand against the moving plate. Green light flashed across the mark. The plate veered sideways under his palm and slammed into the floor beside Leo, splitting one corner and spraying chips across the work area.

Rafael staggered with it and caught the wall with his left hand.

"Stay there," Leo said.

"I am."

Water burst through the seam the plate had uncovered.

It came low and fast through a crack no wider than Severin’s thumb, spreading across the floor toward the route behind them. Armin was already moving.

He uncovered his marked left hand and pulled the existing seawater sideways, bending the stream into the older drainage groove he had cleared during the earlier test. More water followed, and he held the flow there to keep the retreat path dry.

Within seconds, sweat stood along Armin’s hairline despite the cold cavern.

Leo glanced at him. "Stop before you cook yourself."

"I know."

Rafael swallowed and shut his good eye for a moment. When he opened it again, he kept one shoulder against the wall.

"Route?" Leo asked.

Armin looked behind them. "Clear."

Leo pulled the cut section free, and they finished the second gap fast without skipping the sequence. He damaged both exposed ends. Rafael, steadier now, placed the wedges while Severin held the tissue cold, and they packed stone into the missing span until neither end could draw across it.

Leo checked downstream, then tested another mapped point. "Second route is quiet."

Rafael added the result to the page.

At the third conduit, Leo’s first pulse made the smallest two fingers of his marked hand jerk against the wall. He waited, flexed them once, and tested again.

"That one’s carrying more than the other two did."

Rafael checked his earlier notes. "Same contact point?"

"Same."

"Outer routes and shelf?"

"No new response. Shelf is still weak."

Leo looked down the passage behind them. Armin was holding the diverted water with his face flushed, and Rafael had stopped swaying but kept close to the wall. Then Leo looked at Severin.

Severin flexed his right hand. His fingers felt slow, though they still answered.

"You can do another?"

"One."

Leo held his gaze for a moment. "We finish it."

They opened the final casing. The exposed conduit looked swollen against the broken mineral edges.

Severin put his right palm on it. Heat climbed through his hand and forearm as he pulled. The tissue cooled, then warmth returned from deeper in the wall. He narrowed his attention to the strip beneath his palm and drew harder.

His fingers grew reluctant to move. When he shifted his weight, his body followed a fraction late. His next breath arrived with the same delay, and his pulse had slowed enough that he could feel the space between beats.

"Suppressed?" he asked.

Leo tested. "Not enough."

Severin increased the pull until the conduit dulled beneath his palm.

Leo sent another pulse. "There. Hold."

Even Severin’s nod felt delayed. Leo started the saw.

The corridor moved before he finished the first cut.

Mineral skin on Severin’s side drew inward by inches while the opposite surface bowed toward the workface. The space around the four of them tightened, but behind Armin the retreat passage stayed open.

Leo’s marked hand was still against the monitoring point when the wall shifted around his wrist. He tore it free.

"Contact gone."

"Exit is clear," Armin said at once.

Rafael checked past him. "Still open."

Leo did not waste time hunting for another monitoring point. "Continue."

The saw bit through the first cut while Severin kept pulling. His thoughts had begun to drag behind what he was seeing. He watched Leo shift the blade several inches and only a moment later caught up with why.

"Severin."

"I’m here."

"Keep it down."

"Trying."

Leo started the second cut. The conduit tightened around the blade, and Severin drew more heat until the pale tissue stiffened again. His right arm wanted to sag, so he locked the elbow and kept his palm planted.

The saw broke through. The severed middle length snapped loose, and the wall contracted.

A fractured strip of mineral dropped from above Rafael. He saw it late but stepped into it, catching the moving piece against his marked right hand. The fall veered sideways under his palm just enough for the strip to strike the floor instead of Armin’s shoulder.

Rafael dropped to one knee with it. Armin cursed under his breath and released part of the water hold. The redirected stream widened across the drainage groove but stayed off the main retreat.

"Enough," Leo said. "Just keep the way out clear."

Armin nodded, breathing hard, sweat running down his temple.

Leo kicked the severed section clear and crushed the first exposed end with the chisel. Rafael, still on one knee, pushed a wedge into place while Severin held the other end cold. Leo drove the chisel into that end twice, splitting it, then packed the missing span with stone and drove the final wedge home.

"Done."

Severin let go. His hand came away slowly, and he stayed crouched rather than find out too quickly whether his legs had kept pace with the rest of him.

For several seconds nobody touched the wall. Water ran through Armin’s diverted channel. Rafael breathed through his nausea with one hand flat on the floor, while Leo rubbed the fingers of his marked hand and watched the three packed gaps.

The gaps held.

Leo checked the first downstream point, then the second. Neither returned anything.

At the deeper side of the severance line, he pressed his left hand to the wall and waited longer. "Active."

Rafael looked up.

"Deep side is still active."

Severin sat back against his heels. The deeper structure had stayed alive while the mapped routes beyond the cuts had gone quiet.

Leo pointed toward the known outer branch they had used during the mapping tests. "I need one small pull."

Severin flexed his right hand again. The delay had eased, though it had not disappeared. "Small."

He moved to the outer branch and placed his palm against it, taking only the shallow amount of heat they had used while mapping. Leo pressed his marked hand to the deeper side and waited.

"Nothing."

Severin held the change for a few more seconds.

Leo tested again. "Still nothing."

Severin released, and they went to the treatment shelf last. Leo checked the same positions he had used before the cuts, his marked hand resting against the stone through two low pulses.

"Weak return," he said. "Spread out. Same as before."

Rafael turned a page in the field book. "Across the cut?"

"No."

Leo returned to the white line. On the deeper side, the wall still answered him. Across the three missing sections, none of the mapped outer routes carried the response.

Rafael had his pencil ready.

Leo looked at him. "Rafael, record the time. Containment starts now."
