The crack ran under Tarin's boots like a live thing trying to choose where to bite.
One instant he had Jori's arm in his hand and the brace cart bucking sideways beside him. The next the floor split along the inside rail seam with a sound that felt bigger than noise, something he took through his legs and spine before his ears made sense of it. Stone sheared. Metal wailed. The bad patch under the cart dropped half a foot and took the left wheel with it.
"Lift him!" Daska shouted.
They tried.
Tarin got both hands under Jori's torn arm and heaved. Sell caught the man's belt from the other side. Harlan, one sleeve dark with blood, abandoned the cart for a heartbeat and grabbed under Jori's shoulder. For one promising, miserable second the trapped rear hand came up enough to scream properly.
Then the cart shifted again and drove its weight deeper into the fracture line.
Pell let go with one hand long enough to jam his pry bar under the wheel hub. "Now, now, now."
The whole section shook.
The chain above shrieked hard enough to flatten thought.
Krail kept shouting from somewhere behind the line, but his words came to Tarin in pieces at first. Move the brace. Stabilize the load. Do not abandon issue property. The kind of sentences a man built when he still believed a report might save him from reality.
It was only when Tarin heard, clear as hammered iron, "Cut him loose and move the brace," that the truth of Krail's priorities settled all the way in.
Not discovery, exactly.
Confirmation.
Pell turned his head and looked at the foreman with open disbelief. "You cut him loose."
Krail had no answer ready for a subordinate's disgust. That alone told Tarin something useful about the man. Cruelty came easier to him when paperwork stood between the order and the flesh.
Jori made a choking sound and tried to wrench free on his own. The trapped ankle held. The broken floor pinched tighter around it.
"Don't," Tarin snapped.
"Then move me."
"Working on it."
The first hookclaw, the one still loose under the scaffold, skittered through the iron supports with a wet clicking sound that kept shifting place. Tarin could not tell if it was circling for another strike or only trying to save itself from the collapse. Either way, the gallery had passed the point where intentions mattered.
Stone started falling in earnest after that.
Not boulders yet. Fist-sized pieces. Slabs of old patch mortar. Dust sheeting from seams overhead. One chunk clipped Kest's shoulder and spun him sideways into the wall. Daska grabbed the young man by the harness strap, shoved him back on his feet, and shouted, "Light up. If that lamp dies, I'll drag your ghost back here to relight it."
Kest lifted the lamp with both hands this time.
The brace cart lurched again.
Pell swore. "Wheel's gone. We lose it now or it takes the line with it."
"Leave the cart!" Daska shouted.
Krail reacted as if she had proposed treason. "No."
Daska turned her head and fixed him with a look Tarin would remember long after the rest of the morning blurred. "Then stay and write poetry for it."
That cut through even Harlan's pain for a breath. Tarin saw the quick savage grin flash across his face and vanish.
The crew broke around the choice.
Sell and Tarin hauled Jori free the moment Pell levered the wheel far enough off the trapped leg. Something tore in Jori's ankle or knee. Maybe both. The man howled, and Tarin nearly lost his grip from the force of the movement alone.
"Can you stand?" Tarin asked.
Jori spat blood and said, "Ask prettier questions."
Good enough.
They dragged him.
Harlan fell back to them despite the wound in his shoulder. "Give him here."
"You can barely use that arm."
"Still attached, isn't it?"
Tarin shifted Jori onto him. Harlan took the weight and grunted white-faced but stayed upright. Sell grabbed Jori's belt from behind. Daska had the rest of the line moving toward the wider turnout they had come through, driving them back by voice and posture alone while Pell covered the retreat with the pry bar and the lamp.
Krail did not follow.
Tarin looked back once.
The foreman stood by the brace cart with one of the quarter hands, both of them still trying to free the trapped side as if enough stubbornness might reverse structural failure. Tarin could not tell whether Krail truly believed salvage could still be saved or whether abandoning it in front of witnesses would have felt worse to him than death.
The route answered for him.
The broken chain collar above the cart tore out of the wall.
It did not explode. It ripped free with a grinding metal shriek and a spray of stone the size of fists. The chain whipped down in a black arc. One length struck the scaffold. Another slapped the rail bed and rebounded. The collar housing came after it, spinning once in the air before smashing through the cart's brace stack.
The patched floor disappeared.
Cart, salvage, foreman, and one screaming quarter hand went with it.
Tarin did not see them land.
The hole they left opened under the branch like a new throat.
And that should have been the end of the damage, if the section had not already been failing far past that point. But the break had gotten into the work beneath the work. Beneath the patching, beneath the guild notes, beneath whatever optimistic inspection line had let men keep feeding weight through this corridor for one more profitable week.
The failure ran.
It went under the rail bed and up the scaffold supports and into the wall seams with the hungry speed of a lie finally called out in public.
"Move!" Pell roared.
Nobody needed telling.
The gallery bucked under Tarin's boots. Jori nearly went down again. Harlan caught him with the good arm and cursed so hard it came out sounding prayerful. Sell shouldered into them both and kept the three of them moving by force and spite.
Daska was thirty paces ahead, getting Kest and Namin through the worst of the narrow section. Pell stayed between the crew and the sounds in the dark. The hookclaw under the scaffold lunged once toward the rear and got half buried when a support plank dropped across its back. It shrieked and vanished into dust.
That did not improve anything.
The left wall split from floor to shoulder height in a long zigzag line. Wet grit blew out of it in a sour burst. One of the cross braces overhead snapped and fell tip-first into the rail bed where Tarin had been aiming his next step. He jerked aside and took the blow of Jori's weight badly, almost twisting his own ankle out from under him.
The widened turnout chamber came into view through sheets of drifting dust.
So did two other crews running the other way.
For one stupid second, the branches met in pure human confusion. Men seeing other men in panic and trying to decide if joining them made survival more or less likely. Then someone shouted, "Chainway's gone," and that did the sorting.
Everybody ran.
The turnout chamber had already stopped behaving like architecture.
Men from the crossing crews slammed shoulder-first into each other and rebounded through dust thick enough to make everyone look half made of chalk. One cart had overturned in the rush, spilling brace wedges and bundled chain dogs across the floor. A porter with half his face gray from stone powder kept trying to gather them back by instinct, as if an orderly pile of hardware might somehow persuade the route to remain a route. Someone else hauled him bodily away before the next shower of grit could bury that kind of loyalty for good.
Daska planted herself in the middle of the confusion for one heartbeat and turned it into traffic.
"Outer wall," she shouted. "No center line. If you trip, you get dragged."
A stranger from the other crew barked back, "By who?"
Daska did not even look at him. "By whoever wants to live longer than you do."
That was enough. Men moved.
Tarin felt the chamber's shape only in fragments while they fought through it. The slope under one boot. The slick stripe where some oil line had burst. The low crack of a lantern frame going under a wheel. Harlan's breathing turning raggeder beside him. Jori hanging more weight on them with every other step, trying and failing to hide how close he was to losing sense entirely.
Then the first real dust wave hit them from the branch collapse behind.
It came warm and thick, loaded with powdered stone, rotten timber, and the bitter old-metal stink of torn chain. Tarin turned his face into Jori's shoulder by reflex and kept hauling. Men coughed blind all around him. The lamps in the chamber went ugly and diffuse behind the cloud, every one of them suddenly looking too small for honest use.
Daska used the chaos better than Tarin thought possible. She shoved one stranger toward the outer wall, grabbed Kest by the strap before the boy could get clipped under another crew's cart, and got her own line through the intersection by shouting simple things in a voice that left no room to choose badly.
"Right wall."
"Not there."
"Keep breathing."
"Move him."
Pell reached the chamber last and had just enough time to look back before the narrow branch behind them folded in on itself. The collapse came through as dust first, then broken scaffold, then a roll of stone and chain that filled the throat from wall to wall.
"Well," Pell said, coughing. "That answers the route question."
They did not stop.
The turnout chamber should have been safer. Wider floor. Two exits. Better roof bracing. Instead it only gave the collapse more room to spread. One rail line lifted under hidden pressure and slammed back down crooked. A chain transfer wheel dropped from its mount and shattered on the stone. Men from the crossing crews were shouting names now, some theirs, some not. Someone had lost a lamp. The dark thickened in ugly pockets between the surviving light.
Jori finally slipped free of Harlan's grip and hit one knee.
Tarin lunged for him.
"Leave me," Jori gasped.
"No."
"Tarin." Harlan's voice cracked from pain. "Move."
But Tarin had already planted himself and hauled Jori upright again. Not because it was sensible. Because he knew what happened to men who got left in bad places while other men did the sensible thing.
Brann on the cot came and went through his head in a bright useless flash.
The route made its choice.
The floor under the inner rail dropped without warning.
Not enough to open into a clean pit. Enough to break line and balance. Tarin and Jori went sideways together. He grabbed for the nearest solid edge and caught the lip of a shattered platform instead of stone. The rotten board snapped under his weight. Jori's sleeve tore in his fist. Harlan shouted his name from somewhere above and to the left.
Then the chamber floor let go beneath him.
He saw it in chopped pieces as he fell. Daska braced against a side beam, one arm reaching. Pell flattened to the wall with the lamp clamped in his teeth. Sell dragging Jori by one ankle and not letting go. A rain of bolts and grit. One dead-white look of Harlan's face through the dust.
Then no one.
He hit once on a projecting beam hard enough to drive pain clear through his shoulder and spin him. Hit again on rock. Felt himself slide, then drop, then smash through something brittle and timbered. The lamp tore free and vanished. Darkness rushed up like another blow waiting for him.
He tried to catch at the wall and got skin full of stone instead.
The last thing he heard before the black took him was the long buried groan of lower construction giving way under upper neglect, the whole district speaking its real language at last.
That should have been the end of thought.
Instead his mind kept surfacing in strips while the body finished the rest.
He was aware, for one terrible instant, of going through layers. Modern route first, all bad patching and hurried brace work. Then something older that cracked cleaner when he hit it. Then another level of darkness with enough vertical space inside it to make the falling feel private again.
A beam caught him across the shoulder and spun him.
His hand slammed against some smooth cut wall that did not belong to the broken gallery above. The contact lasted no longer than a blink, but even through the shock he knew it for worked stone of a quality Chainway had never wasted on debt-haul corridors.
Then came another impact, lower and uglier, through hip and ribs.
After that the fall became sliding, then rolling, then one last sudden drop through a brittle lattice that burst around him like old ribs.
When he finally struck still ground, the silence waiting there felt older than the collapse.
Darkness did not keep him cleanly.
He came back to himself in flashes while still moving.
A slamming strike to the back of one shoulder.
A burst of powder-dry dust in his mouth.
One wild glimpse of chain whipping in a shaft wider than the space around him should have allowed.
Then another drop.
He hit sideways through what felt like old timber lattice and landed hard enough to fold around the pain. The breath left him in a grunt he barely heard. He tried to drag in more and got stone grit, old dust, and the hot iron taste of blood.
Still falling, some part of him thought stupidly, even while the rest understood he had stopped.
Something above gave way with a muffled boom. Debris rattled past. One length of board struck his thigh and bounced away into deeper dark. A smaller stone clipped his temple and made the black tilt again.
Tarin lay still because stillness was the only possession left to him.
When the world steadied enough to hold shapes, he understood three things at once.
He was not dead.
He was not where the other crews would think to look first.
And whatever had broken under Chainway was older than Chainway by a long time.
The air had changed.
Less wet iron. Less route stink. Less lamp smoke. Under the dust and blood there was another smell now. Dry stone kept shut too long. Old wood. Mineral cold untouched by the breath of active traffic.
He turned his head and saw nothing but black and one thin floating brightness far away that might have been his lamp or might have been pain misbehaving. The floor under his cheek felt wrong for current route work too. Flatter. Harder. Less grit worked into it.
Above him, the collapse kept settling in diminishing little ticks and throat-clearing groans, as if the district were still deciding how much of him it meant to bury.
He wanted to call out.
Wanted it in the stupid ordinary human way, because shouting names into wreckage was what men did while the hope still had warmth in it.
But the ribs on the right side hurt badly enough to make wasted breath a stupid choice. And even if he spent it, what then? Daska maybe too far away to hear. Pell pinned under another break. Search crews not yet organized. Krail gone into the hole with the salvage and whatever his clean coat had been worth.
No.
The dark would get his name when it earned it.
Tarin closed his hand around nothing, loosened it again, and let the pain take him the rest of the way down into unconsciousness because there was no practical fight left in him for the moment.
