Chapter 2: What the Bronze Carried

The second casualty bell did not ring again.

Elias pressed his cheek to the bronze iris and listened until the metal scorched a line beneath his ear. Behind him, the ruined bridge ticked and settled over the shaft. Tar smoke clung to the back of his throat. His right knee pulsed inside the brace, each beat forcing the swollen joint harder against leather straps already wet with blood.

“Cassian.” Elias struck the iris twice with his buckle. “Stop hitting the door.”

The answering blow shook dust from the upper frame.

“That sounded distressingly unlike stopping.”

Cassian’s voice came through the bronze as a warped growl. “Move away from the seal.”

“I’m sitting beside a bottomless shaft with one useful leg. My opportunities for moving away are limited.”

Another metallic groan ran around the iris. Cassian had found leverage on the other side. Strong, immediate, and likely to turn the entire housing into falling scrap.

Elias dragged his buckle across the floor until it caught the narrow brass tube running from the iris frame into the wall. The casualty bells used mechanical lines. Pull a station handle, tension a wire, trip a hammer. Simple enough to survive heat, bad weather, and official maintenance.

He placed two split fingers against the tube. Its vibration had almost faded.

Then he struck the conduit with his buckle: three evenly spaced knocks, a pause, then one.

Identify signal. Can you respond?

For five breaths, the floor gave him only the hiss of hot tar below. Then something tapped from deep inside the wall.

Three knocks. A pause.

One.

The person who had rung the second bell had heard him—and had answered.

“Alive,” Elias said.

The forcing noise beyond the iris stopped.

Cassian spoke first. “Certain?”

“No. I often exchange pleasantries with dead plumbing.”

“Vale.”

“Deliberate spacing. Correct return. They’re alive enough to understand a casualty query.”

A faint scrape came through the seal, followed by Mara’s thinner voice. “Ask if they can move.”

Elias looked down at his own leg. “Excellent question.”

He tapped twice, paused, then gave the movement query. The response came slowly. One knock. Two. One again.

Not the current signal.

Elias repeated the query. He held his breath, keeping his fingertips on the tube. The pattern returned exactly, each impact transmitted through brass into bone.

“One-two-one,” Mara said through the iris. “What does that mean?”

“I don’t know yet.”

Cassian’s tone hardened. “Then don’t call it proof.”

“It’s a repeated answer from a living person. That qualifies as proof in several unfashionable disciplines.”

Elias shifted his weight. His boot moved two inches. The knee twisted inside the brace, and white pressure wiped the landing from sight. His shoulder struck the bronze. He waited with his teeth locked until the shaft and wall returned to their proper positions.

No standing, then.

He loosened the top strap before the swelling trapped it permanently. The release sent a hot tremor from kneecap to hip. His palm slipped on blood and tar when he reached for the cut end of the rescue rope still looped around his waist.

“Status,” Cassian demanded.

“Bad knee. Burned hands. Sealed floor. One casualty ahead.”

“Your status.”

“That was the edited version.”

Mara coughed. The sound had a wet edge. “He can’t stand, Cassian. He couldn’t before the door shut.”

Silence followed. Cassian had received his answer and disliked every useful part of it.

Elias laid a snapped bronze brace from the bridge rig alongside his right leg. He threaded the cut rope behind his thigh, around the existing knee brace, and down across his boot. Each knot had to be pulled using his wrists because his fingers no longer closed properly.

“What are you doing?” Cassian asked.

“Making the joint incapable of surprising me.”

“That is not the same as stabilizing it.”

“No, but it is cheaper.”

He cinched the rope. The bronze splint bit from thigh to ankle, locking the leg almost straight. Pain remained, broad and nauseating, but the knee could no longer fold sideways without dragging the whole limb with it. Crawling had become possible. Standing had not.

A muted clang came from Cassian’s side.

Elias knocked once, sharp. “Tell me you did not put the bar back in.”

“I removed the control cover.”

That checked Elias’s reply.

Cassian continued, “You wanted me to stop forcing it. I stopped. Give me something better to do.”

Mara made a quiet sound that might have been approval or pain.

Elias leaned toward the lower edge of the iris. Heat breathed from a finger-wide vent beneath the frame. “Outer housing should have three stamped plates. Timer, drive, brake.”

“Four plates.”

“Read the fourth.”

“Manual separation.”

There it was.

Elias followed the casualty conduit with his hand. It entered the iris frame beside a recessed service panel almost hidden under black tar spatters. Two screw heads held it shut. He worked the buckle’s tongue into the first slot.

“Open the manual separation housing,” he said. “Do not move anything.”

Cassian gave a humorless laugh. “An order?”

“A procedure. You may refuse it after I explain that the iris drive is under stored tension and could take off your hand.”

A pause.

“Procedure accepted.”

Metal scraped on both sides of the seal. Elias turned the first screw a fraction at a time, changing hands whenever his burned fingertips failed. The second screw had warped in the heat. He wedged the buckle under the plate and leaned until its corner peeled outward.

Hot air struck his face. The cavity smelled of grease, copper, and blood from his own hand.

Inside, a toothed drive wheel rested against a smaller timer gear. Or should have. A hooked bronze pawl had been pulled between them, separating the timer shaft from the iris clutch. Red grains continued to tremble through a glass channel above, their movement translated into a gear that now turned nothing.

“Cassian. What do you see?”

“Drive wheel. Brake arm. Separation lever is down.”

“Does the timer gear meet the drive?”

“No.”

Mara’s voice came closer to the housing. “The sand was above the last mark when the iris started humming. I watched it. Then the door closed, and the sand kept falling.”

“Could you have mistaken the mark?” Cassian asked.

“No.” Her answer cut through the bronze without force. “My face was against the glass while you pulled the rope. There were three finger-widths left. I used my blood to mark the level.”

Elias pictured her hand on the timer housing, injured and fresh from the bridge, preserving evidence while Cassian tried to reach him.

“Mara,” he said, “is the mark intact?”

“Yes.”

“Do not wipe it. Do not let anyone reset the timer.”

Cassian answered for her. “No one touches it.”

Elias put his buckle against the pawl and lifted gently. It moved half a hair, then stopped under load. Along its upper edge, four bright cuts scored the darkened bronze. The grooves were too narrow for a fall impact and too fresh to have gathered grease. Someone had inserted a tool and hauled the pawl down.

The metal around the cuts remained warm.

“The separation wasn’t triggered by the timer,” Elias said. “The pawl disengaged it.”

“Mechanical fault?” Cassian asked.
