He came upon the lake without any warning. The trees to the right suddenly ended, and before him was a great expanse of water, dotted with tiny islands. Never in his life had Alvin seen such quantities of the precious liquid: he walked to the edge of the lake and let the warm water trickle through his fingers.

             The great silver fish that suddenly forced its way through the underwater reeds was the first nonhuman creature he had ever seen.

             As it hung in nothingness, its fins a faint blur of motion, Alvin wondered why its shape was so startHngly familiar. Then he remembered the records that Jeserac had shown him as a child, and knew where he had seen those graceful lines before. Logic told him that the resemblance could only be accidental—but logic was wrong.

             All through the ages, artists had been inspired by the urgent beauty of the great ships driving from world to world. Once there had been craftsmen who had worked, not with crumbling metal or decaying stone, but with the most imperishable of all materials— flesh and blood and bone. Though they and all their race had been utterly forgotten, one of their dreams had survived the ruins of cities and the wreck of continents.

             At last Alvin broke the lake's enchantment and continued along the winding road. The forest closed around him once more, but only for a little while. Presently the road ended, in a great clearing perhaps half a mile wide and twice as long. Now Alvin understood why he had seen no trace of man before.

             The clearing was full of low, two-storied buildings, colored in soft shades that rested the eye even in the full glare of the sun. They were of clean, straightforward design, but several were built in a complex architectural style involving the use of fluted columns and gracefully fretted stone. In these buildings, which seemed of great age, the immeasurably ancient device of the pointed arch was used.

             As he walked slowly toward the village, Alvin was still struggling to grasp his new surroundings. Nothing was familiar: even the air had changed. And the tall, golden-haired people coming and going among the buildings were very different from the languid citizens of Diaspar.

             Alvin had almost reached the village when he saw a group of men coming purposefully toward him. He felt a sudden, heady excitement and the blood pounded in his veins. For an instant there flashed through his mind the memory of all Man's fateful meetings with other races. Then he came to a halt, a few feet away from the others.

             They seemed surprised to see him, yet not as surprised as he had expected. Very quickly he understood why. The leader of the party extended his hand in the ancient gesture of friendship.

             "We thought it best to meet you here," he said. "Our home is very different from Diaspar, and the walk from the terminus gives visitors a chance to become—acclimatized."

             Alvin accepted the outstretched hand, but for a moment was too astonished to reply.

             "You knew I was coming?" he gasped at length.

             "We always know when the carriers start to move. But we did not expect anyone so young. How did you discover the way?"

             "I think we'd better restrain our curiosity, Gerane. Seranis is waiting."

             The name "Seranis" was preceded by a word unfamiliar to Alvin. It somehow conveyed an impression of affection, tempered with respect.

             Gerane agreed with the speaker and the party began to move into the village. As they walked, Alvin studied the faces around him. They appeared kindly and intelligent: there were none of the signs of boredom, mental strife, and faded brilliance he might have found in a similar group in his own city. To his broadening mind, it seemed that they possessed all that his own people had lost. When they smiled, which was often, they revealed lines of ivory teeth—the pearls that Man had lost and won and lost again in the long story of evolution.

             The people of the village watched with frank curiosity as Alvin followed his guides. He was amazed to see not a few children, who stared at him in grave surprise. No other single fact brought home to him so vividly his remoteness from the world he knew. Diaspar had paid, and paid in full, the price of immortality.

             The party halted before the largest building Alvin had yet seen. It stood in the center of the village and from a flagpole on its small circular tower a green pennant floated along the breeze.

             All but Gerane dropped behind as he entered the building. Inside it was quiet and cool: sunlight filtering through the translucent walls lit up everything with a soft, restful glow. The floor was smooth and resilient, inlaid with fine mosaics. On the walls, an artist of great ability and power had depicted a set of forest scenes. Mingled with these paintings were other murals which conveyed nothing to Alvin's mind, yet were attractive and pleasant to look upon. Let into the wall was something he had hardly expected to see—a visiphone receiver, beautifully made, its idle screen filled with a maze of shifting colors.

             They walked together up a short circular stairway that led them out on the flat roof of the building. From this point, the entire village was visible, and Alvin could see that it consisted of about a hundred buildings. In the distance the trees opened out into wide meadows: he could see animals in some of the fields but his knowledge of biology was too slight for him to guess at their nature.

             In the shadow of the tower, two people were sitting together at a desk, watching him intently. As they rose to greet him, Alvin saw that one was a stately, very handsome woman whose golden hair was shot through with wisps of gray. This, he knew, must be Seranis. Looking into her eyes, he could sense that wisdom and depth of experience he felt when he was with Rorden and, more rarely, with Jeserac.

             The other was a boy a little older than himself in appearance, and Alvin needed no second glance to tell that Seranis must be his mother. The clear-cut features were the same, though the eyes held only friendliness and not that almost frightening wisdom. The hair too was different—black instead of gold—but no one could have mistaken the relationship between them.

             Feeling a little overawed, Alvin turned to his guide for support— but Gerane had already vanished. Then Seranis smiled, and his nervousness left him.

             "Welcome to Lys," she said. "I am Seranis, and this is my son Theon, who will one day take my place. You are the youngest who has ever come to us from Diaspar: tell me how you found the way."

             Haltingly at first, and then with increasing confidence, Alvin began his story. Theon followed his words eagerly, for Diaspar must have been as strange to him as Lys had been to Alvin. But Seranis, Alvin could see, knew all that he was telling her, and once or twice she asked questions which showed that in some things at least her knowledge went beyond his own. When he had finished there was silence for a while. Then Seranis looked at him and said quietly:

             "Why did you come to Lys?"

             "I wanted to explore the world," he replied. "Everyone told me that there was only desert beyond the city, but I wanted to make sure for myself."

             The eyes of Seranis were full of sympathy and even sadness when she spoke again:

             "And was that the only reason?"

             Alvin hesitated. When he answered, it was not the explorer who spoke, but the boy not long removed from childhood.
