The corridor to the map chamber had a draught in it that Soren had forgotten.
It came up from the lower passages of the Cave smelling of wet rock and pulled at the edge of him as he walked, the way a slow current pulls at a moored boat. He had not come this way in twelve days. He had not decided to stop. The campaign map had needed nothing for weeks, the maps of Nessar's surge he had left to Ithra the Sila, and somewhere between the two the habit had slipped out of his hands.
He came now because Ithra had asked, and had not said why.
She was already inside, standing to one side of the display with her hands folded.
Two maps hung there. The first was the surge. He had seen it at its height, the human world spotted red from edge to edge like a fever rash. The red had thinned. From the door it looked much the same; up close it had gone patchy. Over it Ithra had laid a paler wash, the counter, spreading across the same ground, and where the pale had come first the red had drawn back furthest, the way a stain draws back from clean water poured on it.
The second map was his own.
She had made it without being asked. Three hundred and twenty-four dots, one for each sorcerer named at the start of the purge. Three hundred and eight closed in the first phase. Four since, the travellers, closed when they settled where his assignees could reach them. Three more after those, barriers his readers had finally read through.
Nine left. Three barriers that had not given. Six held by something outside jinn law. Beside each of the nine Ithra had drawn a small mark, a short line with a ring at one end, the sign he had taught her four hundred years ago for a matter seen and set down. Noted, not pursued.
Ninety-five percent. The campaign had been built to reach that ceiling, and it had reached it.
"You wanted me to see this," he said.
"I wanted you to see it."
"Why?"
"You haven't been here in twelve days."
"That is not a reason."
"It's a reason."
He let it go and read the maps the way he had read maps for centuries, without hurry, letting them say what they had to say. The campaign was over. The surge, which he had not started, was failing. The counter, which he had not built, was working. What he had held up by will these last months was standing on its own legs.
He felt no triumph. The end had been designed, and reaching it was the absence of failure, a river arriving at the sea it had always been running toward. The concealment had been voided. The sorcerers who hid behind it were closed, and the pattern was gone from the live pacts for a generation. Except for one line, the ledger lay flat as still water.
"The pointer," Ithra said, as if she had heard him reach it. "It's one name now. I've run the other three to the ground. They were where they said they were."
"And the one."
"Tamar. Harun's brother-in-law. He hums by the eastern seep, and he was there for every hum after the boy died, and he was the one you looked at." She did not lower her voice. "I have nothing else. No trade, no visit to the human side I can prove. I have where he stands and how often."
"Then you have a hum and a glance."
"Yes."
"I will not stand in front of the elders on a hum and a glance." He looked at the nine small rings on the second map. "Leave it open."
She did not argue. She took a stylus from her sleeve and, on the margin of his campaign map, where there was no dot for it, drew a tenth ring.
There was one other thing he had done outside the maps. When he first opened his file on Muhammad, he had sent Harun and two other quiet watchers to stand along the paths an enemy might use to come at the man. They were there still. He had not spoken to the man. He had not briefed the tribes. He did not know whether he would.
The light in the chamber came from the display, flat and even. His shadow lay behind him on the floor, thicker than that light could cast it. It had been so since the descent. He no longer looked.
"You're thinking something," Ithra said.
"Something I would rather not say. I'll say it, because you brought me here to hear something."
"Then say it."
"If Kael had not died, none of this would have happened. Not this way. The concealment might have run ten more years. Nessar was waiting for a trigger, and without this one he would have waited for another. The counter would not have risen in this shape. The man might have come at another time, for other reasons."
"Yes."
"One young jinn died in a human bedroom, and the whole human world has bent around it."
"Yes."
"I don't know whether that is a comfort or an accusation."
She did not answer. Questions of that kind made her uneasy, and she dealt with them by leaving them alone, which left room for him. He stood with it. He had lived long enough to know which questions settle where they rise and which sink and lie on the bottom. This one would lie on the bottom. He let it go down.
They walked out together. At the junction where her corridor split from his, she stopped.
"There's another question."
"Yes."
"Shape it for me."
"The campaign is done. The surge is failing. The counter needs nothing from me. Nessar will rebuild in his own time. The tribes will hold without my leading anything." He stopped. "The cause that gave my grief somewhere to run is nearly used up. What am I for now, Ithra?"
She looked at him a moment. She had known he would ask it. She had brought him to the chamber so that he would, and her part was to be there when he did. The look said what it had said at other crossings in their long work: you will find it.
Then she went down her corridor.
In his quarters he sat on the bench he had used for private thinking for longer than most of the tribe had been alive.
He did not think about the campaign. He thought about Kael as a boy, and about the way he had asked questions, slowly, one laid on the last, circling until the answer he wanted came in sight. One evening he had circled for most of an hour, the old offensives, the passes, which lines had held, and Soren had seen where he was going long before he got there. When the question came, it was about his father. Soren had answered it in three true sentences and gone back to the reports on his bench. Kael had thanked him and left. He had left his lamp burning in the passage that night, a small waste he allowed himself when he was thinking, and in the morning the wick was black to the root and the oil pot cold. Soren had filled it again without a word and called that care. He had kept the boy's lamps full for ten years and given him three sentences about his father.
Soren could not now remember the three sentences.
He opened the small chest beside the bench. The jewel lay where he had put it, wrapped in grey cloth. He unwrapped it and held it on his palm. It was smaller than he remembered, green, cold, and it gave off no light at all. The lamp threw his shadow up the wall behind him, darker than the lamp could account for.
"What am I for?" he asked it.
The draught answered first. It came in under the door from the lower passages, smelling of wet rock, and on it, faint and tuneless, rose the sound of someone humming by the eastern seep.
Soren closed his hand on the jewel.
