They left the barge. Only one torch burned now on the deck. Some of the lights had died around the square. This was deserted, but there was still sound and movement in plenty along the streets that led into it. Carey guided Arrin to the left along the canal bank. He did not see anyone watching them, or following them. The sounds and the lights grew fainter. The buildings they passed now were empty, their doors and windows open to the wind. Deimos was in the sky, and some of the roofs showed moonlight through them, shafts of pale silver touching the drifted dust that covered the floors. Carey stopped several times to listen, but he heard nothing except the wind. He began to feel better. He hurried Arrin with long strides, and now they moved away from the canal and up a broken street that led toward the cliffs. * * * * * The street became a flight of steps cut in the rock. There were roofless stone houses on either side, clinging to the cliffs row on ragged row like the abandoned nests of sea-birds. Carey's imagination, as always, peopled them, hung them with nets and gear, livened them with lights and voices and appropriate smells. At the top of the steps he paused to let Arrin get her breath, and he looked down across the centuries at the torches of Valkis burning by the canal. "What are you thinking?" Arrin asked. "I'm thinking that nothing, not people nor oceans, should ever die." "The Ramas lived forever." "Too long, anyway. And that wasn't good, I know. But still it makes me sad to think of men building these houses and working and raising their families, looking forward to the future." "You're an odd one," Arrin said. "When I first met you I couldn't understand what it was that made Derech love you. You were so--quiet. Tonight I could see. But now you've gone all broody and soft again. Why do you care so much about dust and old bones?" "Curiosity. I'll never know the end of the story, but I can at least know the beginning." They moved on again, and now they were walking across the basin of a harbor, with the great stone quays towering above them, gnawed and rounded by the wind. Ahead on a crumbling promontory the shaft of a broken tower pointed skyward. They came beneath it, where ships had used to come, and presently Carey heard the jingling and padding of animals coming toward them. Before the rise of Phobos they were mounted and on their way. "This is your territory," said Derech. "I will merely ride." "Then you and Arrin can handle the pack animals." Carey took the lead. They left the city behind, climbing to the top of the cliffs. The canal showed like a ribbon of steel in the moonlight far below, and then was gone. A range of mountains had come down here to the sea, forming a long curving peninsula. Only their bare bones were left, and through that skeletal mass of rock Carey took his little band by a trail he had followed once and hoped that he remembered.
