The cell door opened without a key.
Ezekiel stayed where he was for one stupid heartbeat, hands braced on the floor, eyes fixed on the iron bar lifting clear of its brackets one careful inch at a time.
No warden stood in the corridor.
No execution clerk.
No one shouting his name for the walk upstairs.
Just the scrape of worked metal moving where it should not have moved, and the lamp outside the cell guttering lower as if the light itself had decided to mind its own business.
Then a tall figure stepped into the watch-light.
Not a dwarf. Not a clan officer. Not anyone who belonged under the east stand.
The stranger wore dark clothes without rank marks, travel dust, or arena soot. He did not hurry. He did not look around. He looked straight at Ezekiel, then past him once, as if confirming the cell held exactly what he had come for and nothing more.
"Up," he said.
Ezekiel's body tried to obey before his mind caught up.
He stopped it by grabbing the edge of the sleeping shelf.
"Who are you?"
The stranger's gaze did not change. "Someone the wardens will notice too late."
That was not a useful answer.
It was also worse than no answer.
Ezekiel pushed himself to his feet anyway because the open door already made the old rules irrelevant. His knees complained. His shoulder burned where the wall had caught it earlier. The dried blood around his nails felt hotter now that a living witness had arrived to see it.
"If this is some kind of trick-"
"Then staying put will improve your odds."
The stranger stepped back once.
Ezekiel moved to the threshold and looked into the corridor.
Two wardens lay along the wall outside. Alive, as far as he could tell. One had slumped sideways with his keys still in hand. The other was down on one knee as if he had tried to rise and forgotten how. Neither had a visible wound. The iron relay box beside the watch post hung open in a clean split from top to hinge, not smashed, just opened too neatly to belong to any tool Ezekiel knew.
He looked back at the stranger.
That face did not help.
Too calm. Too deliberate. Like something carved to watch a gate, not walk through one.
"You did that?"
"Can you walk?"
Again: not useful. Again: worse because it did not need to be.
Ezekiel swallowed.
"Yes."
"Then choose. We leave now, or you wait here until the next set of boots arrives."
That at least was honest.
Ezekiel stepped over the first warden and nearly caught his foot in the man's dropped key ring. The stranger was already moving down the corridor. Not fast. Just with the confidence of someone who had decided the shape of the next few minutes and saw no reason for the world to argue.
Ezekiel followed because execution was a known quantity and this wasn't.
The prison underworks ran deeper than most arena watchers knew. Cell row. Warden post. Storage arch. Then a furnace passage used in winter to keep the lower stones from icing over. Ezekiel had only seen half of it when he fought under the east stand as a boy and got lost looking for the wash channel.
He knew enough to know the stranger had chosen the right direction.
"How did you get in here?" he asked.
"Through the parts your wardens stopped checking."
That made Ezekiel wish he had asked something else.
They turned past the ledger alcove. A bell chain hung beside the next arch. One tug on it would bring the upper watch running.
Ezekiel opened his mouth.
A guard stepped into the passage from the corner before he could warn anyone.
The guard saw them.
His hand went to the chain.
The stranger lifted two fingers.
The iron hook above the chain bent inward with a dry crack. The bell rope jerked once, caught, and stopped. The guard's hand hit it anyway and got nothing but a frayed end and his own breath coming back at him too fast.
Then the stranger crossed the distance between them.
No flourish.
No lunge.
One step, one hand at the guard's throat, and the dwarf hit the wall hard enough to lose the rest of the moment.
The stranger let him slide down breathing.
Ezekiel stared.
The guard had been broad across the chest and carrying full kit. The stranger had handled him like a door that needed opening.
"Move," he said.
Ezekiel moved.
At the next turn the furnace passage widened into a service court stacked with slag buckets, oil drums, and a chained lift cage that carried rig parts between the lower yard and the maintenance floor. Above them came the first real sign that the prison had understood something was wrong.
Boots.
Shouts.
Not close yet.
Close enough.
"The lift takes too long," Ezekiel said before he could stop himself.
The stranger looked at him for the first time as if he might be more useful walking than tied to the problem.
"Another way?"
Ezekiel pointed toward the ash sluice arch on the far side of the court.
"Waste channel. It comes out behind the east smelter sheds. Nobody uses it unless something catches fire."
"Good."
They cut across the court. Halfway there, one of the upper yard alarms finally found its courage. The bell did not ring cleanly; it coughed once, then again, as if the same wrongness from the arena floor had reached into the metal here too. Even so, the sound was enough. Doors thudded open overhead.
Ezekiel ducked instinctively.
"They're going to close the yard."
"Then we leave before the order arrives."
The ash sluice gate was barred from the inside by an old wheel valve and a rusted crosspin thick as Ezekiel's wrist. He grabbed the wheel and felt at once that it was locked hard with old mineral crust.
"It sticks."
The stranger rested one hand on the pin.
For a breath nothing happened.
Then the metal frosted white from his fingers out.
The crust split.
The crosspin cracked in the middle like old bone.
Ezekiel did not say anything because he had run out of sensible things to say several corridors ago. He just hauled the wheel, got the gate moving, and squeezed through after the stranger into the narrow reek of the sluice tunnel.
The channel curved under the outer wall in a low crawl lined with soot and old wash residue. Twice Ezekiel slipped. Twice the stranger caught him by the collar and put him back on his feet without breaking stride. By the time they reached the grated mouth behind the east smelter sheds, Ezekiel's lungs felt as if they had been scrubbed with sand.
Night air hit him cold and filthy and wonderful.
Behind them the arena bells were going properly now.
Not just one.
Three.
East stand under breach. Gate watch to hold. Yard search to spread.
Anyone on this side of the district would know it inside a minute.
Ezekiel staggered behind a stack of slag molds and braced both hands on his knees.
"You could have left me there," he said.
The stranger stood in the shadow of the shed wall, listening to the city rearrange itself around the alarm.
"Yes."
Ezekiel waited.
That seemed to be the whole answer.
"So why didn't you?"
The stranger finally turned to him.
"Because what happened in the arena was not only your mistake."
That cut through the panic faster than the cold had.
Ezekiel straightened.
"You know about the hum."
"I followed it."
Not luck, then. Not mercy. Not some drunken ancestor finally taking pity on him from beyond the furnace smoke.
Something had gone wrong in the arena.
This man had known it.
Worse, he had come looking for it.
"What are you?" Ezekiel asked.
The stranger held his gaze long enough for regret to become a practical bodily sensation.
"Called Void," he said. "I'm tracking the same damage that found your rig."
Still not useful. But more than before.
The bells kept hammering over the district. A squad crossed the lane mouth at the end of the shed row carrying lantern poles and hooked staves. Void did not so much as glance at them. They passed without looking their way once.
Ezekiel saw then what had felt wrong since the cell.
Void never seemed to belong to the same piece of space as everyone else. Not invisible. Not hidden. Just placed one narrow step to the side of ordinary notice until he chose otherwise.
That realization settled poorly.
"You asked if I could walk," Ezekiel said. "You didn't ask my name."
"I heard it often enough in the arena."
Fair.
Mostly unfair, but not incorrectly unfair.
"Then you know I didn't mean to kill him."
"Meaning it would have changed less than you think."
Ezekiel almost snapped back at that. Then stopped, because the man was not talking about guilt. He was talking about the rig, the floor, the hum in the metal. About something that had been waiting there whether Branik or Ezekiel or anyone else had deserved it.
That was somehow worse.
"If you came for the breach," Ezekiel said carefully, "why take me with you?"
"Because you heard it."
Ezekiel frowned.
"Only at the end."
"You still heard it. Most in that arena only heard blood."
Another squad crossed the far lane, this one turning toward the lower steps that led to the labor quarter. Void watched them go, then looked back.
"I need a craftsman who studies failure instead of hiding it under honor."
For a breath Ezekiel thought of every forge master on the west terraces and discarded them all.
Then he thought of Frederick.
The answer landed with enough force to make him wish it had not.
"I know one."
Void said nothing.
That silence was somehow an order to continue.
"My father," Ezekiel said. "People call him the Crazy Dwarf because they don't like not understanding him."
"Do you?"
Ezekiel let out something that might have been a laugh if the night had been kinder.
"Not consistently."
Void accepted that as if it matched what he expected of fathers.
"Where is he?"
That part hurt more than the arena.
"Gone north," Ezekiel said. "Months now. Maybe longer. He found something on an old route and told no one enough to stop him."
"You have no way to follow."
"I didn't say that."
Void's attention sharpened.
Ezekiel hated himself a little for answering before he had decided to.
But the bells were still ringing.
The arena wanted him dead.
And the man standing in front of him had opened a prison built to end arguments.
At that point honesty was not virtue. It was arithmetic.
"He keeps copies," Ezekiel said. "Of maps. Notes. Mechanisms. Everything. He says trusting one version of anything is how stupid people become dead experts."
"Where?"
"My room. Lower forge quarter. Behind the old ventilation brick."
Void stepped away from the wall.
That single movement carried more certainty than a full speech from most men.
"Then we go there."
Ezekiel did not move.
Void looked back once.
"If you are thinking about running," he said, "do it after I have what I need. Before that, it only wastes both our time."
That should have sounded arrogant.
It sounded factual.
Ezekiel pushed off the slag molds and followed him into the night because he had reached the point where one impossible thing had become easier to trust than a city full of ordinary ones.
They crossed the labor quarter by alleys, drain walks, and one abandoned tram cut where the stones still held the day's machine heat. Twice more patrols passed close enough that Ezekiel tasted fear properly. Twice Void moved them through it without hurry, and the patrols kept on with their lanterns and search hooks and no sense at all of what had gone by.
By the time they reached Ezekiel's building, the bells had spread farther uphill. Window shutters were opening. People were already assembling the night's story out of fragments.
The loft room looked exactly as he had left it that morning.
Tool rack.
Narrow bed.
Two unpaid notes shoved under a cup.
And the loose ventilation brick beside the furnace flue.
Ezekiel knelt, pressed the left edge twice, then pulled the brick free. Inside lay an oilskin roll, a brass key blank Frederick had once called promising, and three folded pages packed into the gap against soot-black stone.
Void took the roll first.
He opened it on the worktable under the single lamp and read without comment. His eyes moved once across the route marks, once to the northern water notations, and once to the cramped side column where Frederick had written three alternate landfalls in case the sea forgot its manners.
"This is your father."
It was not a question.
"Yes."
The stranger rolled the map shut.
At last, some small kindness from the night: the answer seemed to satisfy him.
"Good," he said. "You will take me to him."
