Chapter 94: THE CINDER-SINK
The fire-grid was still burning in the basin, hot enough to melt steel. Hot enough for anything Aiden needed.
Aiden looked back once at the ice wolf moving through the fire.
All that fire and I can’t touch a stick of it.
He watched a handler light the next row. Then he turned his back on the whole basin and walked west.
Two hours west of the basin, the fruit still hissed against his chest through his coat.
The fruit was burning down. Slowly. But slowly was still a clock.
"You feel it," he told Cinder.
She had kept her nose against his chest the whole walk, right over the fruit.
"I know. Believe me. I’m carrying your dinner, and I can’t let you eat it." He shifted away from her. "Of all the ways I imagined disappointing you, this one is new."
She followed him, hungry steps and low posture all the way.
The Hound’s low note had forced her hunger back once. The hunger returned the moment the Hound was out of reach.
Aiden picked the cat up at the drainage cut.
It had come with them to the basin, but stopped when it saw the fires. Aiden couldn’t get it any closer.
It had returned and waited there the whole time.
It climbed Cinder’s foreleg to her shoulder. It smelled the fruit. It felt her hunger.
Then it settled against her jaw with the air of something arriving to supervise.
"You missed it," Aiden told it. "Big gold dog. Looked at me like I was the wrong man holding the door."
The cat washed a paw.
"You’d have hated it. It would have out-stared you without trying."
The cat didn’t believe him. It believed it out-stared everything.
It out-stared a forge once. The forge blinked first.
Let it keep that.
He went back under the city at the dead hour, against the current.
This time Cinder banked without being asked.
He came up into the undercroft. The smith’s heat bled down through the floors above.
The old man was still working at his bar when Aiden entered the forge.
He looked at the fold in Aiden’s coat before he looked at Aiden’s face.
"You got it."
"I got it."
Aiden unwrapped the fruit on the bench in the forge-light. It hissed and glowed there, warm as something alive.
The smith did not touch it.
Miasma climbed from the kit bag onto the bench beside it. She put her nose close to the cut skin and pulled back at once.
Nyx never came near the fruit. It stayed behind Aiden’s back the whole time.
"And before you say it," Aiden told the smith, "I know it’s not enough. I can’t let her have it yet. You know why."
"The room."
"The room."
"I told you the next form needs real fire." The smith nodded at his own banked forge. "She needs a place hot enough to hold the threshold open while she changes. That is a man’s forge. It’s hot. It isn’t Chamber-hot."
"How hot does it need?"
"Ember-motes in the air thick enough to breathe."
"And where’s that?"
"The only place in this city that’s got them that thick is the room behind the wall she’s been sleeping against."
"The Hearthstone Chamber."
"The Hearthstone Chamber. Door reserved to D-rank tamers. Vane seal. Your name crossed off the list," the smith said it flatly.
"So what happens if I do it in your forge instead?"
"The threshold opens. It can’t hold. The fruit burns through her before the change is finished."
"And then?"
"Then you’ve spent the fruit. Whatever you put into her is gone with it. She comes out half-evolved and worse than she started." The smith did not blink. "There’s no second fruit on that tree until next season’s lightning."
"I know. I counted them."
"Then count this too."
The old man picked up his iron and put it down again.
"Get it even slightly wrong, and the cure kills her."
Aiden stood with the fruit hissing between them.
Behind him, Cinder came to the bench. She put her head beside the fruit. She did not try to snatch it.
She waited.
She doesn’t know what he just said. She knows from his face that it was bad news.
Halbern’s sewer map had tunnels on it nobody else knew. The proctor taught me nobody guards some of them.
Every district in this city is built on a floor it has forgotten about.
The Chamber door is guarded. The forgotten passages underneath aren’t.
"I don’t go through doors," he said. "They never allowed me to. I come up from underneath."
The smith waited.
"All that heat has to go somewhere." Aiden looked at the brick around them. At the heat coming down. "Something that hot, sealed behind stone, has to leak."
"Down." The smith stopped working the bar. "There’s a place where the Chamber leaks. The motes settle there and pool. Too rich to waste. Too deep under the wall for anyone to bother guarding."
He set the iron aside.
"They call it the cinder-sink."
"Is it Chamber-hot?"
"Might be. I’ve never been down. Nobody goes down." He looked at Aiden. "It’s a sink for a reason."
"Then that’s where we do it."
Aiden turned to Cinder.
"We found you a forge. It’s a sewer. Naturally it’s a—"
"There’s a catch," the smith said.
Of course there is.
"Nobody guards the sink. That doesn’t make it yours." The smith set the bar down. "A charter on a fire covers the stone it sits in. Top and bottom. There’s no gate down there because nobody’s ever needed one. Walk in anyway and you’re on Vane’s ground again."
"So the sink is Harken’s too."
"Same as the room above it."
"That I expected."
"This you didn’t."
The old man looked at the fruit. Then at Cinder, with her nose still turned toward it.
"A heavy haul came in on the river last night. While you were east. Cradle-mounted. Too big for the dock, so they took the load to the deep-water gate."
Aiden went very still.
"Which gate?"
"The one that opens onto the under-channels."
Cold went down Aiden’s back.
"The under-channels that feed the cinder-sink."
"The same."
Aiden did not say anything for a moment.
"The room on the river."
"The Ice Heart." The smith said the name like something he’d rather not have in his mouth. "That’s what they call it."
"They brought the Ice Heart under the wall."
"Into the bottom." The smith held his gaze. "The same bottom where you want to burn that fruit."
Inside Aiden’s coat, Nyx went cold against his ribs.
You heard that.
You’re the only one of us who works better in the dark.
"The one room hot enough to make her," the smith said. "And they’ve just put the one thing cold enough to unmake her in it."
He did not soften it.
Aiden looked at the fruit. It was hissing itself down to nothing on the bench.
Then at Cinder wanting it.
Then at the brick under his boots.
The forge and the freezer. Same basement.
"Right," he said.
Quietly. No joke in it. He had learned where the joke stopped.
"Of course it is."
