THE MOON · NINE DAYS LATER
The god had been on the Moon for nine days and had not yet been asked to do anything.
It sat on the ring floor, forty metres below the gallery glass.
A ball of stopped time, blue-violet. The letter Ω stood on its face, and under the letter there was nothing at all.
Beside it the Hōgyoku spun in its cage, throwing slow petals of light up through the floor.
The Hōgyoku was the door Aizen had spent two lifetimes building. It still would not stay open longer than his instruments took to notice it.
Above the great ceilings the base had gone the blue of two in the morning. Urahara's weather was running a thin unnecessary rain for the sound of it.
Aizen stood at the rail and let the other two arrive in their own time.
He wanted the account. Nine days of work, said out loud, by the only two men alive who could give it to him.
Gin came first. He folded himself into a chair without appearing to bend anywhere.
Urahara came second, clogs clicking, with a tray he had not been carrying in the corridor. Three cups, a covered dish, and a small brass lamp with a chip of grey-gold stone where the wick should have been.
"Eat that, both of you. Somebody has to." He set the lamp down with a good deal of ceremony. "Nine days, and I've had precisely one useful thought about your rock."
"Say it," said Aizen.
"It's a rock." Urahara sat. "A very large rock, and I'll grant you it's warm. Congratulations, Aizen. I've cleared a shelf."
"You have had nine days and a crate of it."
"I have." He tapped the lamp. The chip of stone did nothing whatever. "Second night, I put a splinter of it under a glass and asked it for light. Nothing."
"It won't run a lamp. It won't warm a cup. It won't turn a wish into so much as a candle flame."
The fan appeared and shut again.
"Every physicist on this Moon has spent nine days calling it a mineral with an unusual property. It isn't a mineral. It never was one."
He looked at the dead grey-gold chip.
"That's a bone. I have twelve kilos of bone and a very tidy shelf."
Gin had been reading the rock since it came through the gate. He read everything, the way other men breathe.
"Bone's fair," he said, eyes shut. "It's what's left after."
"Bone will do," said Aizen.
"You've not cut anything since you came through," Urahara said. "Nine days, and you've only looked."
"Sold the cutting." Gin's eyes stayed shut. "A year to the day, for six tenths of one per cent."
"Was it worth it?"
"It was exact," Gin said.
Urahara had gone quiet. He was not looking at the shelf any more.
He was looking down through the glass at the warm unhurried thing on the ring floor, which had not stopped being alive.
"Nine days," he said, "and I have been asking the wrong object."
"Yes."
"The shelf is a corpse. The stone converts nothing, because the thing that did the converting is downstairs in a bubble, dreaming."
He put the lamp down the way a man sets down something he has just decided is expensive.
"Every prayer on that planet went up a vein and came back as an answer. The stone was only the pipe it travelled along."
"I have spent nine days standing over the plumbing, asking the pipe why the water tastes of nothing."
"It took me four months," Aizen said. "You had nine days and a shelf. I would not be too hard on yourself."
"I want an hour with it. Supervised, shielded, and I will sign whatever appalling document you like."
The grin came back and did not reach anywhere near his eyes.
"Aizen. If that thing downstairs turns wanting into result, then cursed energy is not a law of the world either. It is a service somebody is providing."
"And a service can be interrupted."
For the first time that evening Aizen looked unguardedly pleased. A law cannot be switched off. A service has somebody at the other end of it, and somebody can be reached.
"An hour," he said. "Not tonight."
At the far end of the table lay a shōgi board, lacquered eleven times by a boy who had said ten.
Nobody had touched it since supper. Eleven of the forty pieces were still blank wood, waiting to be carved.
They had been playing with the blanks anyway. A blank piece was whatever Gin had last said it was.
"He is two moves from taking that," Aizen said.
"Three," said Urahara.
"Two."
Gin's smile widened by perhaps a millimetre. "Two," he agreed, and did nothing about it.
Twenty-two of the finest minds ever lifted off Earth were asleep three levels up. Not one of them had ever sat down in this room.
It had never been forbidden. It simply never happened.
* * *
"Nine days is a generous holiday," Aizen said. "The account, please. Simuria first, since it is the only item that is finished."
He gave it standing, in the voice he kept for a plan. It came out as one finding, and the finding was this.
Every frightened world makes the same material.
On Earth the fear came out through clenched teeth and set hard into something with a grudge, and men called it a curse.
On Simuria the same fear had been answered for two thousand years with courtesy. It set into a body, and into the habit of saying yes.
Same fear going in. Same substance coming out. Nothing in between the two but manners.
"And the wall holds," Urahara said, "or you'd have led with the wall."
"The wall is not a wall." Aizen turned round.
"Their covenant let a god come down a certain distance and stay a certain time. Every soul on that world took those two numbers for the shape of reality."
"They are numbers. I went past them nine times in nineteen days, on a table, in a well-lit room."
"What was on the table at the end of the ninth had no word in their language and has none in ours. It was courteous to me throughout. I have the transcripts."
Urahara had nothing at all to put against that.
"Below us is a heart taken alive out of the middle of a planet."
Aizen looked down through the glass.
"Fifty, on the only scale I have. I built the scale, and I stand at thirty-five on it."
"It is the first thing in this life that has outweighed me. It is lying on the floor of my own accelerator. And it has not yet been asked for anything."
"Second. Four fingers of the King of Curses are loose on the Earth in a lead-lined box."
"They are in the worst possible hands, which are the hands I would have chosen. That item is placed and wants nothing further from me."
"They think they're arming themselves against you," Urahara said, in his brightest voice.
"They are."
Gin laughed once, without opening his eyes.
"Third," said Aizen. "What they know about us."
"One door, three signals, and an anchor." Urahara set the hat straight.
"The door is the thing their man walked in through. Not a curtain and not a barrier. A hole cut between two pieces of ground, and it needs both ends held down."
"The anchor holds the far end of it, nine hundred metres out. It went into the ground before there was a base here to lay it against."
"They know the Moon is inhabited. They know there's a vault three doors and a stairwell down. They know there were twenty-one of us and not one of us a soldier."
"All of it went to them from me. On a plate. With a sprig of something."
"The workmanship is the part worth having," Aizen said.
"Ah," said Urahara. "Yes."
"Their door fails in sunlight. It wants an anchor planted at each end and an hour agreed in advance. It carries one body and whatever that body can hold."
He said it the way a man reads his own handwriting back to himself.
"I wrote those exact rules for my own door, years ago, because they are the only honest way to build one. Three people alive could have arrived at them. I am one of the three."
"The other two have spent a very long time unable to sit in the same room. One of them has had a thousand years to learn patience. The other has never kept one face long enough to need any."
"Something has introduced them to each other. Whatever it was frightens them more than they have ever managed to frighten one another."
"And that would be you," said Urahara.
"Yes."
He did not say either name. Urahara noticed that.
He also noticed that it was not caution. Aizen was saving the names the way he saved everything, for the evening they would be worth the most.
"Fourth, and then you may both go to bed."
"I wrote a list before there was a Moon to keep it on. Everything on it is something I must have in hand before the work can begin."
"One. A special grade of a certain size, taken alive and whole. Special grade is the top of the scale sorcerers use, and the scale stops there because nobody expected to need more of it."
"That item is on the floor below us, rounded up rather generously."
"Two. Three fingers of the King of Curses, still in the vault under our feet."
"Three. Samples owed to me by a man with no hands to sign with, who has not yet worked out that he will pay them."
"Four. Geto's technique, still walking around Japan inside the man who owns it. The one that collects curses and keeps them, and it ripens on its own if I leave it another year."
"Five. Mahoraga. The thing at the bottom of the boy's shadows that nobody in a thousand years has managed to tame."
"Alive, whole, and not summoned by anybody who means to fight it."
"That's the page," Urahara said.
"That is the page. Every item on it is in hand, or in the vault under our feet, or owed to me by somebody who has not yet realised they will pay."
"There is nothing left to acquire. Only the work."
Gin had not moved since he sat down.
"Aizen-san." His head went over toward the glass. "Nine days, and it hasn't asked us for anything. Not the lamps, not the doors, not me."
The tilt got a little deeper.
"Do you suppose there's a piece of it still down in that ground, four light-years off, answering an empty room? And it can't reach?"
"I don't know," Aizen said, without any weight on it.
Then, because it was true and Gin had earned it, "That is the second time you have had those three words out of me. Nobody else has had them at all."
* * *
"Stage One," he said. "Sixty-one days."
Urahara thumbed the hat back. "What do you need?"
"The ring cleared for a week either side. Everyone off the lower levels. The god held precisely as it is."
"If it goes as designed, nobody in this base will know it happened. If it does not, I would rather the knowing were done by people who can be replaced."
"That's most of my physicists."
"Yes."
"And the last item on the page is asleep three levels up," Aizen said.
The dish went cold on the tray. Nobody reached for it.
"He has been the last item since the afternoon I bought him. He was almost six."
"I drafted the vow myself, in my own words, while his father watched me do it."
A binding vow was not a promise between two men. It was a promise the world itself enforced, and nobody in the whole history of sorcery had ever got out of one.
Aizen turned his cup a quarter-turn with the hand that still did as it was told. He looked entirely content.
"It forbids me to harm him. Directly, indirectly, by act or by omission, for as long as I live."
"Gin, do you know it is the only genuinely interesting constraint anybody has ever placed on me? I could have written it looser. I remember deciding not to."
Gin said nothing, which was not the same as having nothing to say.
Urahara looked at the shōgi board with its eleven blank pieces.
The answer had been on paper for years, in a hand that never hurried.
There was a way to take Mahoraga out of the boy without laying a finger on the boy. A way to send him back to his own people afterwards with everything of his own still in him.
No seam. Nothing the Six Eyes could find, and the eyes in Gojo Satoru's head could find anything.
It was elegant. It required the boy to ask for it himself, out loud, on a day he chose. That was the part that had taken the longest to build.
Urahara set the hat straight and did not ask what the shape of it was. Aizen filed the not asking.
"There is one thing I have never done," Aizen said.
Gin's eyes opened all the way. He did that perhaps twice in a decade.
Then he was on his feet, and neither of them had seen him get there.
"Aizen-san."
"Yes."
He watched the small blue-violet heart of the accelerator turn below him. The god lying beside it. The boy's board on the table where it had been left.
"You both know why I never learned one. A Domain is a sorcerer saying out loud what he is, in a sentence the world has to stand inside."
"And that object down there was always going to change my answer. I have never seen the sense in learning a thing twice."
The smile came. The small courteous one. The one nobody had ever learned to survive.
"It is close enough now. In the spring, I think. Kisuke, clear the floor. And Gin, you may want to sit down for this one."
"I have decided to learn a Domain."
