We lit the furnace at midnight, with every eye in the yard on a twelve-year-old's feather.
Nobody had suggested it. Wren simply walked from nozzle to nozzle with the grey quill held out in front of her, and the crowd parted to let her through. Twelve nozzles. Twelve times the feather stood straight and quivered. When she reached the last one and turned to us with her chin high, nobody cheered. People let out a breath at the same moment, a long soft sound like wind going out of a sail.
"Clear," Wren said.
"Again," I said.
"I just did it."
"Do it again when the coals are in. And again when the first heat comes up. And once more before the first pour."
"That's a lot of times."
"Your father tested it before every firing," I said. "I'd like to be as careful as he was."
She looked at me for a moment. Then she nodded, once, with the solemnity of a person accepting a job, and went to find a second feather.
Tobb laid the kindling. He did it the way he had done it the first time, slowly and with a face like a man at a graveside, and Odda stood at his shoulder and said nothing. When the splits were stacked he looked up at me.
"Your match, claimant."
"It's your furnace."
"It's the Row's furnace. You're the Row's seat." He held out a box of long matches. "Light it."
I took one. My hands were not quite steady, and I was glad it was dark. I struck it against the brick and held it to the paper under the kindling, and for a moment nothing happened, and the whole yard waited. Then the paper caught, and the flame crept up the first split, small and orange and entirely ordinary.
Nobody breathed. Nothing exploded.
The coals took slowly, as the old brick demanded. Tobb fed the fire in careful handfuls, and Odda watched the color of the flame through the inspection port, and every quarter hour Wren walked her circuit of the nozzles with her feather. Hour by hour the firebox warmed from black to dull red to the deep cherry glow I had seen on the first night. By three in the morning the air in front of the furnace shimmered. By four I could not stand within ten feet of it without my eyes streaming.
"Now she's awake," Odda said, and for the first time I saw her smile.

Lyra found me at the edge of the heat, a little after four.
She had been sitting with Marrow's people all night, wrapped in the borrowed cloak, and I had not spoken to her since the day before. I was aware of that in a low, guilty way, like a stone in a boot. She sat down beside me on the cold step, close enough that I could feel the warmth of the furnace on one side and the shape of her silence on the other.
"You told me to stay out of it," she said.
"I did."
"I stayed out of it."
"I know."
"I want you to know I could have helped." She said it plainly, without heat. "The coals took three hours. I could have held the temperature steady. Nobody would have seen."
"Someone would have seen. Someone is watching this yard."
"I know." She pulled the cloak tighter. "That's why I stayed out of it. I'm not asking you to let me. I just want you to know that I decided not to. You didn't decide it for me."
I looked at her. In the furnace light her pale face had a faint orange edge, and her eyes, usually that soft, unsteady blue, were clear and level.
"I made that decision for you the day before yesterday," I said. "At the Hospice. I told you to stay behind, and I didn't ask."
"Yes."
"I shouldn't have done it that way."
"No."
"I'm sorry."
Lyra was quiet for a moment. "Thank you," she said. "That's the second time someone down here has said that to me."
"Who was the first?"
"You. In the cold room, after the stove." The corner of her mouth moved. "You say it more than you think you do."
I didn't know what to say to that, so I said nothing. We sat together and watched the furnace breathe.
"It feels watched," Lyra said, after a while.
"The furnace?"
"The fire. There's something on the rooftops. East side, near the old cooling towers. It isn't mana. It's more like the feeling when someone is looking at the back of your head." She frowned. "It's been there since dusk. It moves a little, and then it stays still, and then it moves again."
"One person?"
"I think so." She hesitated. "It doesn't feel angry. It feels patient."
I looked east. There was nothing on the skyline but the broken teeth of the cooling towers, black against a haze the color of old brass. For a moment I saw nothing at all.
Then, very briefly, something flashed. A small bright wink of light, there and gone, from the top of the second tower. It was the kind of flash you get when sun hits a mirror.
There was no sun in the Undercity.
"I saw it," I said quietly.
"Is it the Broker?"
"I don't know." I kept my eyes on the tower. "It could be someone she sent. It could be someone who wants me to think she did."
"That's a lot of ifs."
"It's all I have."
Lyra considered the tower. Then she put her hand on my sleeve, very lightly, and took it away again.
"Be careful," she said.
"I'm trying."
"Try harder," said Lyra, and went back to the warm side of the fire.
◆
The first pour came at five, and it almost broke us.
Tobb had warned me about the draft. A furnace is only as good as its chimney, he said, and ours had lost half its stack in the fire. The air came up through the coals hot and strong, but the smoke had nowhere clean to go, and by the time the iron in the crucible was white and shivering the whole yard was thick with a grey haze that made people cough and cover their faces.
"She's choking," Odda said, squinting through the inspection port. "The heat's good, but she can't breathe out."
"How long can she run like this?"
"A few pours. Maybe five. Then the flue clogs and the whole box backs up." She looked at me with those small black eyes. "And I don't need to tell you what a backdraft does to a lit furnace."
"No," I said. "You don't."
Kaelen was already looking at the broken stack, thirty feet of black brick crumbling at the top like a stale loaf. "Can it be patched?"
"With what? Mud?"
"With sheet iron," said Marrow. She had come up quietly with her good eye narrowed at the sky. "From the roof of the foreman's office. It's rusted but sound. We could roll it into a collar and fix it to the top of the stack with wire."
"Who climbs?" said Tobb.
Nobody answered.
It was Kaelen who spoke, finally, in the flat voice of a man who has decided something and is not going to be talked out of it.
"I'll go."
"You don't know the stack," said Tobb.
"I know heights. I know rope." He was already unbuckling the empty sword belt, the one he had worn out of habit since the Sitting. He looked at it for a moment. Then he handed it to Wren. "Hold this."
"What is it?"
"Mine," said Kaelen. "I'll want it back."
It took two hours. Four of the Row's strongest men rolled the rusted sheet iron into a crude cylinder while Kaelen tied himself to a rope and went up the outside of the stack, hand over hand, with a coil of wire over one shoulder and a borrowed hammer in his belt. The yard held its breath. Every few feet a brick came loose under his fingers and fell, and every time it fell somebody gasped, and every time he did not.
At the top, thirty feet above the glowing furnace, he fixed the iron collar to the broken rim, wire by wire, bracing it with his boots against the crumbling brick. When he finally lowered himself to the ground, his hands were bleeding, and his face was grey with soot, and he stood for a moment with his head down as though he had forgotten how to be on the ground.
"It'll hold," he said hoarsely.
"For how long?"
"Long enough," said Kaelen, "for you to make your iron."
Wren put his empty sword belt back into his hands. He took it without a word, and I saw him tighten his grip on the worn leather, like a man holding a rope.
◆
By eight o'clock the furnace was drawing cleanly, and we had poured twenty-two brackets.
The rhythm, once it came, was a kind of miracle. Tobb ran the crucible. Odda ran the molds, a long row of sand beds pressed with the shapes of the pieces we needed. The Row's children carried iron from the sorted piles, the singers going straight to the fire and the mumblers to Odda's folding anvil, where six of the strongest people in the district beat them, folded them, and beat them again in a ringing, tireless chorus that could be heard across the Undercity.
I stood in the middle of it with a ledger and a stub of charcoal, and I counted.
Twenty-two brackets. Nine braces. Four rails.
It was nowhere near enough.
"At this rate," I said, very quietly, to Marrow, "we make perhaps a hundred and forty pieces by dawn."
"And we need?"
"Three hundred."
She did not say anything for a moment. She stood with her arms folded, watching Odda's folding crew work the anvil in the red light, and her face did not change.
"The rails take longest," she said.
"Yes."
"They're the heaviest and the longest to cool. If we cast them in the big molds, we lose half a day waiting for them to set."
"I know."
"So we don't wait."
I looked at her.
"We pour them hot," said Marrow. "And pull them from the mold before they've set. Quench them in the trough. It will leave them harder and more brittle than the Forges like, but they'll ring true."
"Will they hold?"
"Under an ore cart? Maybe." She shrugged. "Under an army? No." Her good eye held mine. "But the Forges didn't ask for army iron. They asked for iron."
It was, I realized, exactly the kind of answer I would have given myself. It was careful. It was a little bit dishonest. It was almost true.
"Do it," I said.
◆
At ten, a man in a leather apron walked into the yard with two apprentices and a hammer.
I knew who he was before he spoke. The burn scars on the left side of his neck caught the furnace light, a patchwork of old white skin, and his beard looked like it had been combed by a bear. Hask stood just inside the gate with the grin I remembered from the Pit, but it was not a happy grin. It was the smile of a man who has found something he did not expect to find.
"The order was due at dawn," I said. "You're early."
"I'm curious." Hask looked around the yard. At the glowing furnace. At the sorted piles. At the long line of people passing buckets of coal hand to hand without once looking up. "I heard the fire. I heard the hammers. Nobody's heard hammers in the Row in fourteen months." He raised one eyebrow. "I wanted to see what the noise was."
"It's iron."
"So I see." He picked up a bracket from the nearest cooling bed. It was still warm, and he turned it over in his big scarred hands, studying the weld lines, the grain, the faint blue sheen of the quench. Then he held it out at arm's length and struck it, once, with the flat of his hammer.
It rang.
A clear, high, bell-like note, ringing out across the yard and dying slowly into the grey haze. Every head turned. In the sudden quiet I could hear Tobb breathing.
Hask lowered the hammer.
"Huh," he said.
"Is it good?" Marrow asked.
"It's better than good." He turned the bracket over again, and I saw his eyes narrow. "It's better than what my own foremen are turning out. Who folded this?"
"Odda," I said.
"The old woman?" He glanced at her, and something moved across his face that was almost respect. "I didn't know anyone still did that."
"Nobody does," said Odda. "Nobody has time."
"No." Hask looked down at the bracket. "I suppose that's the problem."
He set it back on the bed with a care that was almost tender. Then he straightened and looked at me, and the grin had gone, and what lay behind it was thoughtful and a little tired.
"One hundred pieces of this, by dawn," he said. "That's the order."
"Three hundred, in all."
"Three hundred." He rubbed his scarred neck. "You'll never make it."
"I know."
"Then why are you still trying?"
I thought about that. I thought about the feather, and the stack, and Kaelen's bleeding hands, and a girl who had decided for herself to stay out of it. I thought about eleven people in a dark hall who had only wanted to keep a fire lit.
"Because the alternative is to stop," I said.
Hask watched me for a long moment. Then he gave a short, hard bark of laughter, and put the hammer back in his belt.
"I'll tell you what I'll do," he said. "I'll go home. I'll tell my foremen the Row is working. I'll tell them not to send a single inspector until dawn." He paused. "That's all I can give you. I can't make the iron come faster. And I can't," he added, more quietly, "stop the others."
"What others?"
Hask looked up at the second cooling tower, black against the brass-colored haze.
"There's a lot of eyes on this yard tonight," he said. "Some of them are mine. Most aren't." He turned toward the gate. "Good luck, boy. Don't make me regret the laugh."
◆
At dawn, the bell began to ring.
It came from somewhere far above, from the Forges, slow and heavy and strange, and every person in the yard stopped what they were doing and turned to listen. Tobb lowered his tongs. Odda lifted her hammer from the anvil. Even the children, passing buckets in the long line, went still.
"That's the warning," Marrow said, very quietly. "One hour."
I looked at the ledger in my hands. The columns were smudged with soot and sweat, but the numbers were clear enough.
Brackets: ninety-one. Braces: sixty-eight. Rails: thirty-four.
One hundred and ninety-three pieces out of three hundred.
One hour.
I closed the ledger. Behind me, the furnace roared, and the folding crew kept hammering, and Wren walked her circuit of the nozzles with a grey feather held out in front of her like a lantern.
"One hundred and seven short," I said.
"Yes," said Marrow.
"Can we do it?"
She looked at the furnace. At the crew. At the great black stack with its crooked collar of rusted iron, holding.
"No," she said.
I nodded slowly.
"But I'd like to see us try," said Marrow.
