Chapter 400: The Ends of the Split

The two ends sat on a cloth on Tobin’s bench, spaced a hand apart, with the drawing between them.

Ren had come from the port along the covered route, his issued cloak and hood fastened and his hand covers secured across the exposed gaps. Maren’s clerk sent him down to the gallery. Tobin and Lenna were waiting beside the pieces Ren had last seen set aside during the removal. The root-layer sample lay in a shallow tray, its attached fibers curled against the soil.

Tobin opened the report to the drawing Ren had received on Dawnspire.

"Movement at the seat is the best explanation," he said. "The footing settled, the seat strained the lining, and the lining split. Escaping heat dried the root layer beside it. As that shrank, the bed lost more support."

He lifted the uphill piece by its edges and turned the contact face toward the lamp. Beside the clean saw cut, the older surface bore a short crushed strip. The split ran out from it across the lining.

Tobin set it beside the drawing and pointed out the corresponding part of the seat.

"This edge had shifted against the lining. The damage on the two surfaces matches here." He moved his finger along the drawn contact. "Most of the pressure came onto this short stretch."

Ren leaned closer. The crushed area stopped before the rest of the contact did. Tobin turned the other retained end toward him; the split continued through it, but its contact face lacked the same concentrated damage.

"If the lining opened first and the seat moved afterward, could that crush it too?" Ren asked.

"It could. Crushing alone wouldn’t settle it." Tobin returned to the uphill piece. "But here it crosses the contact, and the split runs out of that damaged strip. That fits the seat straining the lining. Taken with the settled footing, it’s the strongest account we have."

He lowered the piece onto the cloth, leaving both contact faces visible.

Lenna brought the tray forward. Its label identified the sample’s position beside the breach and the face that had lain toward it. Dark, broken fibers clung to that side; farther in, more of the root mat remained joined.

"This is the sample I kept when we removed the damaged material," she said. "The worst drying was against the breach. We saw the layer drawn away from the stone before we took it out."

Ren remembered the brittle pocket breaking inward into her tray. Beyond it, the lining had been split and the stone discolored. Neither keeper had been able to tell him then which failure came first.

"The heat damage I showed you was part of it," Tobin said. "We place it after the movement now. Once the lining opened, it made the loss of support worse."

"Would the replacement sit on the same footing?"

"The footing stays," Lenna said. "What carries it has to change."

She turned to her survey. The sketch showed the four pillars beneath the settled footing, the two shorter supports and the rib beside the inspection face. Behind them, shading marked the weak ground. Its boundary extended farther uphill than the first cavity had exposed. A thick band with different hatching ran below it and continued beyond both edges.

"I’ve probed down to this," she said, following the band. "It’s cultivated foundation stone. It carries the row across to firmer ground on either side of the pocket. The new support has to reach it."

Ren looked from the boundary to the pillars. The weak ground occupied most of the space behind them.

"How far down?"

"Farther than the old opening let us see. I’ll show you."

Farther along the gallery, the feed slide remained closed at its stop. The removed lining had left an open stretch beneath the bedstone. Tobin held the lamp toward it, showing Ren the damaged seats and the sound contacts beyond them.

The inspection opening was clear. A cloth strip at its edge moved outward into the gallery, where Joss’s tending kept the current along the wall toward the flue. The stair and working side remained free of it.

Ren’s four pillars still widened beneath the settled footing. The two shorter ones and the curved rib supported the exposed section beside it, leaving the root recess open. They had carried the stone since he withdrew his active hold. Lenna’s inspection marks remained visible at their contacts, with later entries on the slate she carried.

"Permanent support first," Tobin said. "Then I seat the new lining. Once we’ve checked it under supply, this branch can go back into service. Joss will keep the passages working throughout."

Lenna raised the lamp to one of the upper contacts.

"These have held. They’ll stay until the new support is carrying their share. The relief opening stays clear, and the surface cover stays secured."

Ren followed her light across the footing, then back to the route where the lining would be fitted.

"And the new release working?"

"I’ll set it up and establish its limits," Tobin said. "After that, we can see which part you’re ready to take."

Tobin lowered the lamp. Ren went up with Lenna to meet Maren.

The moved bed still rested on its receiving blocks uphill of the settled section. Beside the worn wooden marker, the little shoot had grown taller and opened a third leaf. Maren was recording its growth when they reached her.

"Does it go back?" Ren asked. "To its row?"

"When the footing’s repaired and checked." She glanced toward the covered section. "It’s growing well here. I’d still like to put it back."

A runner from the neighboring bed lay across the marker’s base. Ren lifted it clear and eased it back among its own stems, uncovering the worn letters. Maren finished her entry, then brought up the contract and handed him the slate.

His part was support work under Lenna: holding designated upper connections while she prepared the permanent support below, checking the load transferred through his assigned section, and keeping the root recesses and air passages clear. The terms included supervised study of the foundation working he would be helping to repair.

Any later Fire work would be confined to a patch Tobin approved after seating and checking the new lining. Tobin would establish its operating limits and decide when Ren could take over that part of the release. The fee remained as agreed, with the working windows coordinated through the keepers. No material was included.

Ren stopped at the line about the foundation study. In his request from Dawnspire, he had described the bedstone adjustments he could already make and asked for work beyond them. Lenna had put the study into his assignment.

"How much of the foundation will I be working on?" he asked her.

"Your first part is above it. You’ll need to understand what you’re joining to before we change the load."

He read the rest and accepted. Maren entered his agreement beside the contract reference, then handed the slate back for him to check the recorded window.

Lenna waited until he had finished before leading him below.

The new opening lay below and to one side of the old inspection face. Lenna had cut it since his last visit, using her survey to place the shoring. A ladder reached down past the gallery floor to a narrow working space with its own lamp.

Joss stood at the bottom beside a passage mouth in the wall. He held a cloth strip to it as Ren descended. The cloth lifted in the current.

"This serves the beds on that side," he said. "Your supports have to pass around it. Leave room for me to reach the mouth as well."

Ren looked from the opening to the shoring beside it.

"Where will you be checking?"

Joss pointed out the strip’s bracket and the narrow space beneath it, then stepped aside. Lenna checked that Ren could see both before unhooking the lamp.

Its light reached the underside of the settled footing at the top of the face. The pillars met it from the gallery side, with the weak ground exposed behind them. Loose soil and patches of dried root mat remained between the shoring. The pocket extended down more than an arm’s length.

At its lower edge, the material changed. A dense band of cultivated stone crossed the bottom of the cut and continued into both walls. Its branching grain caught the light, finer and more closely joined than the bedstone above.

Lenna held the lamp near it.

"This is the garden’s deep substrate. We can join the footing to it through the weak pocket. It reaches sound ground beyond the damage."

She indicated a cleared patch within reach of the ladder.

"You can put your hand there. I’ve checked the face."

Ren rested his covered palm against the stone. He recognized the cultivated Earth structure, but the connections spread much farther than the patch he had worked beside Nel’s root recesses.

Pressure reached the band from the row above and passed sideways through its grain. Ren followed one connection toward the edge of the shoring. It joined others carrying weight from beyond the opening, spreading its share across several routes before disappearing into the wall. On the opposite side, he reached another junction and lost the pressure’s course where it passed beneath the weak ground.

He returned to the part under his palm. He could feel the different shares meeting there. Following what set those shares was harder; the working continued through stone he couldn’t reach from this face.

"I can follow it to there," he said, indicating the junction. "Then I lose it under the pocket."

"We’ll expose the part we need as the support goes in." Lenna put her hand beside his. "For now, stay with this face."

He traced the nearer connection again, then looked up toward the footing.

"At the top, you want the sort of adjustment I made around the recesses?"

"Yes. We’ll check which connections can take more before you change them. You’ll hold your section while you adjust it, then we’ll check that the change stays when you let go."

Her lamp moved across the face, from the foundation to the footing and the stone still carrying the neighboring beds.

"We have to join those while both sides stay supported. The recesses stay clear, and Joss keeps that passage. You’re starting at the top."
