Chapter 1: Before the Sand Runs Out

The rescue bell struck while Mara’s bridge was coming apart.

Its first note rolled through the shaft, deep enough to rattle Elias’s teeth. The second vanished beneath snapping cables and the bronze iris screaming open behind him.

“Retreat!” Cassian shouted from the threshold. “Vale, back through!”

Elias spat stone dust from his mouth and looked the other way.

Mara hung thirty feet out over the shaft. One hand clutched the bridge mesh. Her other arm lay crooked across a plank that had dropped half its length. Blood darkened her trouser leg below the knee.

The bridge’s far suspension chain tore free.

Bronze links whipped sparks from the wall. The deck lurched, slamming Mara onto her back. Her fingers slipped through one square of mesh, caught the next, and held.

Above the iris, red sand poured through a timer glass.

“Forty-eight seconds,” Cassian called. His voice stayed level despite the metal shriek. “The bridge has lost both far anchors. We withdraw now.”

Elias tested the tarred rescue rope at his hip. Heat from the grinding pulley had already soaked through his gloves.

“Mara!” he shouted. “Conscious?”

She lifted her head. Dust striped her teeth. “Deeply regretting it.”

“Can you feel both feet?”

“One. The left one’s filed a complaint.”

Alive, lucid, and answering usefully. Recoverable.

Cassian had issued the correct retreat order for a failed bridge.

Elias unclipped his safety line and stepped back onto it anyway.

The first plank rolled under his boot. His right knee caught the movement late, grinding bone against swollen tissue, and nearly folded. Elias dropped low, seized the side cable, and waited for the white flash behind his eyes to narrow into something he could see through.

“Vale.” Cassian did not waste breath shouting louder. “If you continue, I close at ten seconds. I will not lose the people beyond this door while we argue with gravity.”

“Reasonable.”

“Come back.”

“No.”

A section of decking peeled away beneath Mara and spun into the dark. No impact returned.

Elias glanced at the ballast chest beside the iris, then at the brass guide ring fixed over the doorway. Their equipment had crossed the bridge in that chest before the far anchors failed. Two hundred pounds, perhaps more with the pitons inside.

Enough to pull one injured climber.

Not enough to pull her gently.

He limped back off the first plank. Cassian caught his harness and hauled him across the threshold before the bridge could buck again.

“You have thirty-six seconds,” Cassian said. “Make your argument.”

Elias dragged the rescue rope through the overhead ring. Hot tar bit into his palms where his gloves had split.

“Chest becomes the counterweight. We feed it over the inner stair. Rope runs through the guide, out to Mara. When I free her, you lower the chest. She comes to you.”

“Across a bridge shedding planks.”

“Mostly across.”

“Mara may strike the threshold.”

“I’ll rig her head uphill and keep one hand on the guide line.”

Cassian looked past him. The timer narrowed toward half empty. “And you?”

“I cross on the standing cable after she clears.”

“With that knee?”

“With the other one, where available.”

Cassian’s jaw tightened. He had people somewhere beyond the vestibule and a floor collapsing behind the last of them. Elias could see the arithmetic in his stare—not coldness, not fear. Weight. Every second spent here belonged to someone else too.

Cassian pointed at the rope. “The guide ring is rated for one body under controlled descent. The chest may shock-load it.”

“Yes.”

“The bridge could rotate and crush her.”

“Yes.”

“You may not make it back.”

“That has also forced its way into my planning.”

“Mara must hear that.”

Elias turned toward the bridge. Cassian could have cut the discussion there. Instead, he had demanded the same thing Elias would have demanded.

“Mara!” Elias shouted. “We can pull you in with a ballast drop. Risks: hard acceleration, collision with the decking, possible ring failure. If it works, you cross first. I may be sealed outside. Do you understand?”

The bridge groaned beneath her. Mara looked up at the red sand, then down between the boards.

“What’s the alternative?”

“We leave now. The deck likely fails before another route reaches you.”

“Likely?”

“Very.”

Her laugh broke into a cough. “You should sell holidays.”

“Do you consent to the haul?”

“Yes. Haul me.”

“Cassian,” Elias said, “your part is voluntary. If you don’t trust the anchor, say so.”

Cassian pulled the rope twice through his braking hook and planted a boot against the ballast chest. “I trust the anchor. I distrust your timetable.”

“Then we agree on the important things.”

“Twenty-six seconds.”

Elias crossed.

He kept both hands on the upper cable and placed his left foot first, making the sound leg take each transfer. The bridge sagged toward the shaft wall. Dust billowed from cracked masonry, dry and bitter on his tongue.

At the third step, his right knee failed.

His boot skated off the plank. The harness snapped tight around his waist, leaving him suspended with one leg through the bridge mesh. Pain ground up his thigh. The joint had swollen enough to press hard against the brace beneath his trousers.

“Vale!” Cassian locked the rope.

“Still attached,” Elias said through his teeth. “A triumph of paperwork.”

He hooked an elbow over the cable and pulled himself upright. That cost four seconds. Perhaps five.

The red glass was nearly two-thirds empty.

From Mara’s position, the doorway looked impossibly small. Cassian stood framed inside it, one hand on the brake line and the other braced against the ballast chest. Elias came toward her crookedly, dragging his right foot whenever the bridge tilted.

He had told her he might not return.

That was the part she believed.

The bridge dropped another inch. Her trapped leg moved with the plank, but her boot did not. Something had punched through the leather and pinned it to the mesh. She could feel warmth gathering inside the boot, then running cold around her heel.

“Don’t pull the spike,” she warned as Elias reached her. “It’s holding something shut.”

He crouched beside her and examined the dark iron shard through the boot.

“Good diagnosis.”

“I charge by the minute.”

“We’re short on those.”

He clipped the rescue line to the shoulder points of her harness, then passed a short loop under her thighs. His fingers worked in a precise sequence despite the blood and black tar coating them.

“Hands across your chest when I call,” he said. “Chin down. Do not grab the bridge once you move. You could lose fingers.”

“The bridge and I have become close.”

“Part amicably.”
