The heat emitter screamed as its casing split beneath Dorr's trapped wrist. The ceiling beam above Yenna's table blackened from the inside, while plaster began falling across the canvas where Vell had arranged the procedure materials.
He could keep the root open for a few more seconds, perhaps enough to pull one more control thread. Then the floor would go, the table would turn with it, and Yenna's exposed core would take the full shock of the interruption.
Dorr had chosen collapse because he could not win cleanly in front of his cameras. Vell understood the calculation, which made the man's smile easier to ignore than the shaking room.
"Abort and move," Yenna said, lifting her chain toward the ceiling, "we can find another place to finish it."
Vell followed the root's violent reaction as the first overhead beam cracked above them. The lock had sensed the overload and was retracting toward the deepest part of her core, where another attempt would give the Directorate time to send a command.
"If I abort now, it keeps the lock route," he said, keeping the parasite core steady, "they can close you again once they find us."
"Then pull it," she said, looking at the burning beam instead of his hands, "what is the part you are not saying?"
The route to the parasite core had narrowed after Dorr's signal hit it. Vell could force the root outward by merging pressure from his own core, using the Forge connection as a bridge between them.
His Grade 1 core had never been built to carry a Grade 2 lock, plus Yenna's damaged channels, plus an overloaded Forge. The technique might complete the severance, but it could crack him apart before it saved her.
"I can merge my core pressure with yours," he said, keeping each word clear, "it gives the root a path away from your healthy channels."
"What does it cost you?" she asked, meeting his eyes as the beam groaned above them.
"It can fracture my core," he said, feeling the heat from the ceiling on his neck, "I might lose the Forge, my Grade, or more than that."
"What does it cost me?" she asked, refusing the answer he wanted to give.
"The root moves through the bridge instead of tearing you," he said, holding the connection at its narrowest point, "you keep the risk from the collapse, but not from the cut."
The answer did not promise safety, because he did not have any to offer. It gave Yenna the actual exchange: her chance at freedom against the damage Vell had hidden inside his own chest.
Another section of beam dropped into the hallway, blocking the stairwell where Dorr's crew had retreated. The inspector had stopped struggling under the table, perhaps assuming the broken floor would finish work he could not.
Yenna looked at the procedure material, then at the black root tightening beneath Vell's hands. Her skin had gone grey with pain, but her grip on the chain remained steady.
"You owe me the whole story about Rynn," she said, speaking through the falling dust, "not a cleaned version where I get the useful pieces."
"I will tell you everything," he said, tightening the connection between their cores.
"You also stop deciding that your damage is cheaper than mine," she said, raising the chain toward a loose beam, "I will not trade one handler for another."
"Agreed," he said, opening the bridge before the building could take the choice away.
The Forge pressure crossed from his core into Yenna's, cold at first and then painfully bright beneath his sternum. Her root recognized the new route as a weakness and lunged toward it, exactly as Vell needed.
He caught the root before it reached the bridge's far end, then pulled it toward the parasite core with everything the Forge had left. Yenna's healthy channels flexed instead of tearing, while the Heat-Skin regulation pattern burned out under the strain.
The bridge did not feel remotely like any useful form of shared strength. It felt like Vell had opened a door inside his ribs and invited somebody else's injury to cross the threshold.
Yenna's core pushed back against the merge at first, not from fear, but because its damaged channels had learned to resist every foreign pressure. She saw the resistance through the read and changed her breathing until the healthy lines settled around his connection.
"The left branch is catching," Yenna said, holding her chain against the table leg, "pull it toward my shoulder, then turn it down."
Vell followed her direction, because she knew the sensation of her core better than any analysis screen. The black root shifted away from the damaged branch and opened a narrower path through the bridge.
Each inch it moved tore a thread of pain through both of them. Vell kept the pressure even, while Yenna used the chain to brace herself whenever the floor shuddered beneath the table.
Dorr watched the procedure from under the fallen beam, finally understanding that the collapse had not made them stop. His free hand scraped across the debris toward the overload dial, searching for a way to make the room fail faster.
"You are feeding it into yourself," Dorr said, his control reduced to a rasp, "it will turn you into the next containment problem."
"Then I will deal with mine," Vell said, cutting a silver hook before it reached Yenna's core wall.
The Forge showed another function of the anchor as the root crossed the bridge. It carried a stored map of every command station that had pinged Yenna's scar during the past three years, each location reduced to a dead numerical trace.
Vell did not chase the data while the dangerous procedure inside Yenna remained open. He fixed the sequence in his memory, because a map was worthless if he let the person who could read it die beneath his hands.
Yenna's chain slipped once when the table leg shifted across broken boards. She recovered the grip before the movement disturbed the bridge, then used the remaining slack to wrap the chain around Vell's waist.
"If you fall, I pull," Yenna said, checking the knot with one bloody thumb, "do not make me drag you through another building."
The warning carried more irritation than fear, which was exactly what he needed. Vell had spent too long treating dependence as a weakness, while Yenna kept proving that a chosen line between two people could be a weapon.
He pulled the root again, taking it past the point where it could return to Yenna's healthy core. The parasite shell caught the leading edge, then shook as the Directorate material tried to burrow through its borrowed red mass.
Vell stopped feeding the bridge for half a beat and used Analyze on the root's exposed side. The new view revealed a hidden release pin, built to detach the anchor if a handler's authority fell into enemy hands.
That pin explained why Dorr had tried to overload the room rather than cut the lock directly. He could not remove the evidence without leaving an instruction trail, so he had chosen a collapse that would erase every body at once.
He cut the release pin before Dorr could trigger it, forcing the root to remain exposed. The action sent a fracture of pain through his chest, but the anchor had lost its final route back to anyone's control.
[Core-pressure merge initiated.]
[Forge overload: 92%.]
Pain cut across Vell's chest in one clean, immediate line of tearing pressure. He tasted iron and saw the black root through the Forge read, but the thing he felt most clearly was his own core taking pressure it could not release.
Yenna saw his knees buckle beside the table and caught the back of his shirt with her free chain. The pull kept him upright without disturbing the connection, turning her limited output into the support he could not provide himself.
"Keep it moving," Yenna said, anchoring the chain around the table leg, "I can hold you for one more minute."
The root fought every inch, branching outward into thin silver hooks whenever he pulled. Vell cut each hook at the parasite core boundary, because letting one return to Yenna's channels would make the whole merge meaningless.
Dust filled the room as the floor sagged near Dorr's pinned shoulder. The inspector finally looked afraid when a broken board sank beneath the heat emitter, taking his trapped arm closer to the opening.
"Ardan," Dorr said, reaching toward the table with his free hand, "you do not know what the Directorate does to failures."
"I know what it does to witnesses," Vell said, refusing to look away from the root.
The lock gave a final violent pull, trying to retreat into the route that had once carried the locator signal. Vell used the merge pressure to reverse it, dragging the entire black knot out through the bridge before the old path could close.
The parasite core cracked as the node struck it, but it held and trapped the root inside its red shell. The silver scarring beneath Yenna's core loosened into inert threads, no longer connected to anything that could hurt her.
Vell felt relief for half a breath before his own core fractured beneath the strain. A hard sound passed through his chest, unheard by anyone else, followed by a loss of balance that went deeper than injury.
[Anchor severance: 89%.]
[Warning: recipient core integrity compromised.]
He could release the bridge and leave the final eleven percent of the anchor outside Yenna's core. Or he could keep pulling while every piece of his own power warned him to stop.
Yenna saw the hesitation in his face, then used the chain to pull a loose ceiling beam away from the table. Her shoulder shook afterward, but she gave him a look that did not allow him to treat her like a fragile reason to quit.
"Finish what we chose," Yenna said, breathing hard, "then we leave together."
Vell drove the final pressure through the parasite core, dismantling the remaining node shell thread by thread. The Forge burned away every line that could still carry a lock command, while his cracked core carried the recoil.
The room lurched as the heat emitter finally cut the weakened beam above them. The floor opened beneath the fallen table, and the anchored chain snapped tight across Yenna's shoulder.
He threw his body across the procedure materials, protecting the parasite core as boards, dust, and a section of wall dropped around them. The chain held Yenna's table level for a single brutal moment, then the whole room began sliding into the butcher shop below.
Behind the falling plaster, the severed anchor started moving backward toward the Forge instead of dying inside the shattered parasite core.
