Diaspar must be many miles away by now, and above him would be the desert with its shifting sand dunes. Perhaps at this very moment he was racing beneath the broken hills he had watched as a child from the Tower of Loranne.

  His thoughts came back to Lys, as they had done continually for the past few days. He wondered if it still existed, and once again assured himself that not otherwise would the machine be carrying him there. What sort of city would it be? Somehow the strongest effort of his imagination could only picture another and smaller version of Diaspar.

  Suddenly there was a distinct change in the vibration of the machine. It was slowing down—there was no question of that. The time must have passed more quickly than he had thought: somewhat surprised, Alvin glanced at the indicator.

  LYS

  23 MINUTES

  Feeling very puzzled, and a little worried, he pressed his face against the side of the machine. His speed was still blurring the walls of the tunnel into a featureless grey, yet now from time to time he could catch a glimpse of markings that disappeared almost as quickly as they came. And at each appearance, they seemed to remain in his field of vision for a little longer.

  Then, without any warning, the walls of the tunnel were snatched away on either side. The machine was passing, still at a very great speed, through an enormous empty space, far larger even than the chamber of the moving ways.

  Peering in wonder through the transparent walls, Alvin could glimpse beneath him an intricate network of guiding rods, rods that crossed and crisscrossed to disappear into a maze of tunnels on either side. Overhead, a long row of artificial suns flooded the chamber with light, and silhouetted against the glare he could just make out the frameworks of great carrying machines. The light was so brilliant that it pained the eyes, and Alvin knew that this place had not been intended for man. What it was intended for became clear a moment later, when his vehicle flashed past row after row of cylinders, lying motionless above their guide-rails. They were larger than the machine in which he was travelling, and Alvin realised that they must be freight transporters. Around them were grouped incomprehensible machines, all silent and stilled.

  Almost as quickly as it had appeared, the vast and lonely chamber vanished behind him. Its passing left a feeling of awe in Alvin’s mind: for the first time he really understood the meaning of that great, darkened map below Diaspar. The world was more full of wonder than he had ever dreamed.

  Alvin glanced again at the indicator. It had not changed: he had taken less than a minute to flash through the great cavern. The machine was accelerating again, although there was still no sense of motion. But on either side the tunnel walls were flowing past at a speed he could not even guess.

  It seemed an age before that indefinable change of vibration occurred again. Now the indicator was reading:—

  LYS

  1 MINUTE

  and that minute was the longest Alvin had ever known. More and more slowly moved the machine: this was no mere slackening of its speed. It was coming to rest at last.

  Smoothly and silently the long cylinder slid out of the tunnel into a cavern that might have been the twin of the one beneath Diaspar. For a moment Alvin was too excited to see anything clearly. His thoughts were jumbled and he could not even control the door, which opened and closed several times before he pulled himself together. As he jumped out of the machine, he caught a last glimpse of the indicator. Its wording had changed and there was something about its message that was very reassuring:—

  DIASPAR

  35 MINUTES

  Five

  The Land of Lys

  It had been as simple as that. No one could have guessed that he had made a journey as fateful as any in the history of Man.

  As he began to search for a way out of the chamber, Alvin found the first sign that he was in a civilization very different from the one he had left. The way to the surface clearly lay through a low, wide tunnel at one end of the cavern—and leading up through the tunnel was a flight of steps. Such a thing was almost unknown in Diaspar. The machines disliked stairways, and the architects of the city had built ramps or sloping corridors wherever there was a change of level. Was it possible that there were no machines in Lys? The idea was so fantastic that Alvin dismissed it at once.

  The stairway was very short, and ended against doors that opened at his approach. As they closed silently behind him, Alvin found himself in a large cubical room which appeared to have no other exit. He stood for a moment, a little puzzled, and then began to examine the opposite wall. As he did so, the doors through which he had entered opened once more. Feeling somewhat annoyed, Alvin left the room again—to find himself looking along a vaulted corridor rising slowly to an archway that framed a semicircle of sky. He realized that he must have risen many hundreds of feet, but there had been no sensation of movement. Then he hurried forward up the slope to the sunlit opening.

  He was standing at the brow of a low hill, and for an instant it seemed as if he were once again in the central park of Diaspar. Yet if this were indeed a park, it was too enormous for his mind to grasp. The city he had expected to see was nowhere visible. As far as the eye could reach there was nothing but forest and grass-covered plains.

  Then Alvin lifted his eyes to the horizon, and there above the trees, sweeping from right to left in a great arc that encircled the world, was a line of stone which would have dwarfed the mightiest giants of Diaspar. It was so far away that its details were blurred by sheer distance, but there was something about its outlines that Alvin found puzzling. Then his eyes became at last accustomed to the scale of that colossal landscape, and he knew that those far-off walls had not been built by Man.

  Time had not conquered everything: Earth still possessed mountains of which she could be proud.

  For a long time Alvin stood at the mouth of the tunnel, growing slowly accustomed to the strange world in which he had found himself. Search as he might, nowhere could he see any trace of human life. Yet the road that led down the hillside seemed well-kept: he could do no more than accept its guidance.

  At the foot of the hill, the road disappeared between great trees that almost hid the sun. As Alvin walked into their shadow, a strange medley of scents and sounds greeted him. The rustle of the wind among the leaves he had known before, but underlying that were a thousand vague noises that conveyed nothing to his mind. Unknown odors assailed him, smells that had been lost even to the memory of his race. The warmth, the profusion of scent and color, and the unseen presences of a million living things, smote him with almost physical violence.

  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 non-human creature he had ever seen. As it hung in nothingness, its fins a faint blur of motion, Alvin wondered why its shape was so startlingly 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 clearin
g 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 towards 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 towards 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 outstretchd 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 grey. 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.

  “No,” he said slowly, “it wasn’t the only reason, though I did not know until now. I was lonely.”

  “Lonely? In Diaspar?”

  “Yes,” said Alvin. “I am the only child to be born there for seven thousand years.”

  Those wonderful eyes were still upon him and, looking into their depths, Alvin had the sudden conviction that Seranis could read his mind. Even as the thought came, he saw an expression of amused surprise pass across her face—and knew that his guess had been correct. Once both men and machines had possessed this power, and the unchanging machines could still read their master’s orders. But in Diaspar, Man himself had lost the gift he had given to his slaves.

  Rather quickly, Seranis broke into his thoughts.

  “If you are looking for life,” she said, “your search has ended. Apart from Diaspar, there is only desert beyond our mountains.”

  It was strange that Alvin, who had questioned accepted beliefs so often before, did not doubt the words of Seranis. His only reaction was one of sadness that all his teaching had been so nearly true.

  “Tell me something about Lys,” he asked. “Why have you been cut off from Diaspar for so long, when you know all about us?”

  Seranis smiled at his question.

  “It’s not easy to answer that in a few words, but I’ll do my best.

  “Because you have lived in Diaspar all your life, you have come to think of Man as a city-dweller. That isn’t true, Alvin. Since the machines gave us freedom, there has always been a rivalry between two different types of civilization. In the Dawn Ages there were thousands of cities, but a large part of mankind lived in communities like this village of ours.

  “We have no records of the founding of Lys, but we know that our remote ancestors disliked city life intensely and would have nothing to do with it. In spite of swift and universal transport, they kept themselves largely apart from the rest of the world and developed an independent culture which was one of the highest the race had ever known.

  “Through the ages, as we advanced along our different roads, the gulf between Lys and the cities widened. It was bridged only in times of great crisis: we know that when the Moon was falling, its destruction was planned and carried out by the scientists of Lys. So too was the defense of Earth against the Invaders, whom we held at the Battle of
Shalmirane.

  “That great ordeal exhausted mankind: one by one the cities died and the desert rolled over them. As the population fell, humanity began the migration which was to make Diaspar the last and greatest of all cities.

  “Most of these changes passed us by, but we had our own battle to fight—the battle against the desert. The natural barrier of the mountains was not enough, and many thousands of years passed before we had made our land secure. Far beneath Lys are machines which will give us water as long as the world remains, for the old oceans are still there, miles down in the Earth’s crust.

  “That, very briefly, is our history. You will see that even in the Dawn Ages we had little to do with the cities, though their people often came into our land. We never hindered them, for many of our greatest men came from Outside, but when the cities were dying we did not wish to be involved in their downfall. With the ending of air transport, there was only one way into Lys—the carrier system from Diaspar. Four hundred million years ago that was closed by mutual agreement. But we have remembered Diaspar, and I do not know why you have forgotten Lys.”

  Seranis smiled, a little wryly.

  “Diaspar has surprised us. We expected it to go the way of all other cities, but instead it has achieved a stable culture that may last as long as Earth. It is not a culture we admire, yet we are glad that those who wished to escape have been able to do so. More than you might think have made the journey, and they have almost all been outstanding men.”

  Alvin wondered how Seranis could be so sure of her facts, and he did not approve of her attitude towards Diaspar. He had hardly “escaped”—yet, after all, the word was not altogether inaccurate.

  Somewhere a great bell vibrated with a throbbing boom that ebbed and died in the still air. Six times it struck, and as the last note faded into silence Alvin realized that the sun was low on the horizon and the eastern sky already held a hint of night.
