Then Leta was up on her feet, while the thin woman held her steady with an arm across her back, and the two walked slowly up and down the room. Leta was getting her strength back. But Daulis still lay like a corpse. Mara could see from Dann's face, as he ministered to Daulis, and the cool inspection the thin woman gave to Daulis, standing to look down at him, that they believed he was dying. And now Mara was grieving because of kind Daulis, who had rescued her: Why have I taken it for granted? Oh, oh, oh; and Dann came hurrying, "What is it Mara? Where is the pain?" But it was her heart that was hurting her, thinking of kind Daulis, dead.

He didn't die, though he was the last to recover. Leta and Mara were practising walking back and forth around the room, and then outside, until the cold from the marsh drove them back in, while he still lay unconscious. They began to eat, mostly the porridge prepared for them by their hostess, who was called Mavid, and was a widow, just surviving here on the rare customers the boatmen brought her — though usually the boats went past to the better inns farther on. She was very good to them. More than once she made Dann sleep, and herself sat up, because she was worried about him. Dann had become thin again, and Mara too. When they stood examining each other, like people who have not met for a while, they knew that yet again they mirrored each other: two tall, thin creatures with anxious eyes deep in their heads.

"Dann, please eat," urged Mara; and Dann said, "Mara, you must eat." And Mavid watched them and said she had had a brother, but he had died, and she thought of him every day of her life. Then she said that without Dann, Mara would have died. He was a wonder of a man, the way he nursed them all, but particularly his sister. There had been a night when she thought that all three of them were dying, and there was no way she could have managed without Dann. He hadn't slept for nights. He had eaten only when she reminded him he must. When it seemed Mara was slipping away, Dann wouldn't let her go; he made her come back, begging her, pleading with her; it positively gave her, Mavid, goose pimples to watch it, she had never seen anything like it — and so she went on.

When Daulis did open his eyes, he saw the three sitting by him, and his smile, his own real smile, not a grimace of pain, made their eyes fill. Leta wept and kissed his hands, and Daulis said, "Dear Leta," and closed his eyes. But next day he was up, and the day after began the tedious business of walking up and down, supported by Leta on one side and Dann or Mara on the other, willing strength back into his legs.

They were a month in that inn. Mavid said she felt that she had a family again. Mara gave her four gold coins. Mavid embraced her, then the others and said she could get her roof mended, and stock her storeroom, and the boatmen would bring her customers. Their coming to her inn was the luckiest thing, and she would never forget them.

From her they learned about the history of the drowned cities. It was a long time ago, she said, and she spread her fingers, and set down her hands on the table, to make ten, ten times — and looked at them to say they understood. "One hundred," said Mara. She did it again. "Two hundred," said Leta. And again. "Three hundred," said Daulis. Three hundred years ago the frozen earth turned to swamp, and down sank the cities.

"You see," said Mavid, "the Ice is beginning to go again. When I was a little girl my parents took me to the northern edge of Ifrik. It isn't very far from here. They showed me the ice cliffs on the other side of the Middle Sea. And that is beginning to fill again. It has been dry, so they say for... for." She looked at her hands, wondering whether to attempt setting them down, fingers spread, but again, and again and again, and gave up the idea, and concluded "a very long time. I mean, a long time."

Now they were going to travel in a boat with a sail, not in one low in the water, but tall, with a good deck and a cabin under it. The water would be deep, or at least have easily-followed deep channels, from here until their destination. Which is where they would start their walk to the Centre.

"And how is it you know all this, all the inns and the ways to travel?" said Dann.

Daulis smiled.

Mara said, "Because we Mahondis stick together, that's it, isn't it?" "Yes. For better or for worse." "I can see what you think." "It's not as simple as that."

"But great plots and plans go on and Dann and I are part of it."

"You are the whole point of it all, I am afraid. I am not going to say any more, because you have to make up your own minds. Knowing you as well as I do now, I am pretty certain what you'll do — but let's leave it there. You'll understand."

The travelling now was much faster, because they sailed straight forward, with no need to dodge about among the shoals and sandbanks. Much deeper beneath them the cities stood on white sand, so Mara looked down, seeing them as birds must have done once. That was Sahara sand down there, the sands that long ago stretched from coast to coast. Cities were as temporary as dreams. Like people. And she thought of Meryx. But when I was sick and dreaming in that inn where you could see the sky through the roof, Meryx was never there. Not once. All the people I've loved — they've gone. There's only Dann now. Only my little brother.

This boatman said there was no need to stop at inns when night came; they could drop anchor and sleep on board. Which they did on the first night; but it was unpleasant, with thick, cold mists creeping about on the water, and lights flitting everywhere, which the local people believed were the eyes of the dead, but the boatman said were insects. The next night they stopped at an inn, a big one, where water was heated for them, and they ate well. Already they were getting strong again, but they needed good sleep and they needed good food. For four nights they stopped at inns, while the boatman grumbled and said they were wasting money: they could sleep for nothing on the boat. They must be rich, he said, and asked for more. All this, the boat and the inns, used up three of Mara's four remaining coins. One left. Leta had all her money: they wouldn't let her spend it. Daulis had nothing very much. Dann threatened to prise out his five, but they made him promise to wait.

When they left the last inn, in the morning, the man and woman who ran it said that a messenger had come very early to ask after them. "From the Centre," they said. "They seemed to think you were late." And they actually nervously looked about them, and spoke in low voices.

"They certainly seem to fear the Centre," said Leta.

"If only they knew the truth," said Daulis.

They stood watching the white sail of the boat fly back the way they had come, like a white bird that hardly notices what it is flying over. As for the boatman, he said he was so used to those old cities down there he seldom looked at them. What for? "Those are finer buildings than anyone can make now so why make ourselves miserable with the comparison?"

They were on a sandy track going north-west that made its way through a pale landscape of bogs and ponds and lakes under a sky where thin, white cloud showed like shreds and streaks of ice on chilly blue. Ice was in their minds because not two days' walk north from here were the shores of the Middle Sea, from where on a clear day they could look to the other side and see the ice mountains, the weight of ice, that Mara and Dann had seen on the ancient map in Chelops — the Ice that covered all the northern half of this world, which was like a ball floating in space. Which had on it crude outlines, one of them Ifrik. Shabis had said that the other similar mass, South Imrik, was a mystery: no one knew what went on there. Some said it had preserved all the old knowledge and was so far in advance of Ifrik it couldn't be bothered with this backward place; others that it was in the same state, too poor to care about anything but itself. All the information about South Imrik came from the past, so Shabis had said.
