The second's hands came up of their own accord, palms out, as if he had walked into a wall of hot smoke, and the Eldest knew the third condition had come.
He did not stop walking. None of the Seven had stopped since the bell. He walked with his hands raised a little before his chest, fingers spread, the way a blind man walks into a room he has been told is full of glass. The others kept their places around him. When the Eldest drew level she felt heat coming off his palms, the dry heat of a hand held too long near a kiln, though nothing stood in front of him but the grain of the substrate. The substrate of the Between ran on beneath them, grained and dry, smelling of a forge that had been cold since before there were forges.
She felt it at her own coarse grain, through the attention the Seven shared. Something in him had been sealed at the making. It had stayed sealed while they sat around the bell through the long interval, twenty thousand years without a word, and now it had come open from the inside, the way a seed coat splits in wet ground. Nothing had reached down to him from the world above. The world above did not know where they were. A thing in him that waited on a certain state of that world had found the state arrived, and had opened.
Her people did not count days. They counted conditions, and they had never hurried one. The second had come in a single finding before gathered tribes. The third came by accumulation: the clearing of the old brokers, the men who had stitched pieces of her kind into the world above with instruments that did not rot on their own. One broker cleared would not meet it, nor ten. It wanted the count at which a generation could be called ended.
That count had been reached somewhere. She knew it the way she knew her own weight.
She took the opened thing from him at her resolution, which was wider than his and coarser. It was a piece of architecture, the first they had ever held.
For the whole long interval the end of the path had been a bearing to them and nothing more. They had walked toward it without knowing its shape. Now one face of it stood in the second's mind, and through him in hers. The outer boundary of the Prison was a weave. Agreements made it, thousands of them, drawn from every age since the contained was set where he lay: oaths sworn and kept, bargains honoured, debts paid down to the last grain. No single strand could hold the contained. Every strand was needed. Nobody tended the weave. It held because each agreement in it kept standing.
And one class of strands had just gone slack. She felt them in the fragment like cold places in bathwater. A pattern of pacts, voided in every record of the jinn, its carriers finished. Whatever those men had added to the weave without knowing it was at its thinnest now.
She did not ask who had voided them. It did not matter to her people who did the world's work, only that it was done.
She knew why they walked. The Seven held that the driving out had been unjust, and that the making itself had left them a door: a death of three lines at once, then the bell, then the conditions, and at the end of them the one in the Prison walking free and the earth going back to those who had it first. That was their reading. She had never doubted it, and it was why her feet did not tire.
None of the six spoke. In the long interval they had not needed speech, and they did not need it now. The fragment settled into the attention they shared and fitted against what each already held. The fourth, who had carried a point on the path since the second condition, laid that point against the new face of the boundary, and one dim stretch ahead of them lit. The path turned there and ran beside the boundary for a long way before it met it.
Then the fifth spoke, which the fifth did not do. His voice came out dry and narrow, a voice that had not been used since the earth was theirs.
"Thinner is not open."
"No," the Eldest said. "Thinner is thinner."
The fifth said nothing more. He had set a fact down where all of them could see it, so that none would mistake the slack strands for a gap.
They did not quicken.
The path took them for a while beneath a stretch where the world of the jinn lay close above the substrate, and the hum of that world passed over them like rain on a roof, voices, errands, quarrels. The Eldest did not look up. None of them did. Her people did not watch the world above. They had no need to: whatever it arranged would open in them when it was time, as the third had opened in the second.
Two conditions remained, and the next was bound to a living man. Their reading gave him no face and no city. It said only that he would come late in the age of the sons of Adam, and that the learned of his people would know him and put their hands in his. When they did, something sealed in another of the Seven would split open, and she would feel it as she had felt this.
Some while after, the second lowered his hands and began to draw.
Nothing in the world above could have seen it. A jinn of the oldest standing would not have seen it either, because the Seven did not walk the medium jinn walk. He drew with his attention in the substrate before him, a figure of lines and angles. It was how he set down a thing he had been given, the way a man who hears a sum in the dark writes it on his palm so as not to lose it.
The Eldest watched the lines come.
First an outline, closed, ragged on one side and smooth on the other, a shore. Around it he laid a second line, wide and loose, that she took for water. Inside the shore he set a ring, small and exact, at the very centre. Then, from the ring, he drew a single line outward, in links, each link a little shorter than the one before.
She waited for the chain to reach the shore.
It did not. The second drew the last link and stopped, and the chain ended short of the water by the width of one more link. He looked at it for a long moment. Then he let the figure hang there, long enough for it to settle into all seven of them, and folded it back into himself.
"It holds," she said.
The substrate took the words without an echo, as it had taken the fifth's. The second inclined his attention toward her at the angle that meant yes.
They walked on. Behind the second, the third had added a mark to his count, and the Eldest felt him set it down: three, out of five, with two left open. Her pace did not change. The second's place among them had changed: he was the carrier of the boundary now, and when they came to stand against that weave, they would come through him.
She held the figure a while longer than the others did. The island, the ring, the short chain. At the very end, where the second had stopped, a small mark was left in the substrate that he had not drawn on purpose, a nick at the end of the last link, as if the link had been worn thin there from the inside by something pulling on it for a very long time.
