As they stepped into the tunnel, they felt the familiar tug of the peristaltic field and in a moment were being swept effortlessly into the depths. The journey lasted scarcely half a minute: when it ended they were standing at one end of a long, narrow chamber in the form of a half-cylinder. At the far end, two dimly lit tunnels stretched away toward infinity.
Men of almost every civilization that had existed since the Dawn would have found their surroundings completely familiar: yet to Alvin and Rorden they were a glimpse of another world. The purpose of the long, streamlined machine that lay aimed like a projectile at the far tunnel was obvious, but that made it nonetheless novel. Its upper portion was transparent, and looking through the walls Alvin could see rows of luxuriously appointed seats. There was no sign of any entrance, and the whole machine was floating about a foot above a single metal rod that stretched away into the distance, disappearing in one of the tunnels. A few yards away another rod led to the second tunnel, but no machine floated above it. Alvin knew, as surely as if he had been told, that somewhere beneath unknown, far-off Lys, that second machine was waiting in another such chamber as this.
"Well," said Rorden, rather lamely, "are you ready?"
Alvin nodded.
"I wish you'd come," he said—and at once regretted it when he saw the disquiet on the other's face. Rorden was the closest friend he had ever possessed, but he could never break through the barriers that surrounded all his race.
"I'll be back within six hours," Alvin promised, speaking with difficulty, for there was a mysterious tightness in his throat. "Don't bother to wait for me. If I get back early I'll call you—there must be some communicators around here."
It was all very casual and matter-of-fact, Alvin told himself. Yet he could not help jumping when the walls of the machine faded and the beautifully designed interior lay open before his eyes.
Rorden was speaking, rather quickly and jerkily.
"You'll have no difficulty in controlling the machine," he said. "Did you see how it obeyed that thought of mine? I should get inside quickly in case the time delay is fixed."
Alvin stepped aboard, placing his belongings on the nearest seat. He turned to face Rorden, who was standing in the barely visible frame of the doorway. For a moment there was a strained silence while each waited for the other to speak.
The decision was made for them. There was a faint flicker of translucence, and the walls of the machine had closed again. Even as Rorden began to wave farewell, the long cylinder started to ease itself forward. Before it had entered the tunnel, it was already moving faster than a man could run.
Slowly Rorden made his way back to the chamber of the moving ways with its great central pillar. Sunlight was streaming down the open shaft as he rose to the surface. When he emerged again into the Tomb of Yarlan Zey, he was disconcerted, though not surprised, to find a group of curious onlookers gathered around him.
"There's no need to be alarmed," he said gravely. "Someone has to do this every few thousand years, though it hardly seems necessary. The foundations of the city are perfectly stable—they haven't shifted a micron since the Park was built."
He walked briskly away, and as he left the tomb a quick backward glance showed him that the spectators were already dispersing. Rorden knew his fellow citizens well enough to be sure that they would think no more about the incident.
Alvin settled back on the upholstery and let his eyes wander round the interior of the machine. For the first time he noticed the indicator board that formed part of the forward wall. It carried the simple message:
LYS 35 MINUTES
Even as he watched, the number changed to "34." That at least was useful information, though because he had no idea of the machine's speed it told him nothing about the length of the journey. The walls of the tunnel were one continual blur of gray, and the only sensation of movement was a very slight vibration he would never have noticed had he not been expecting it.
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 gray, 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 traveling, and Alvin realized 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
5
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 whe
rever 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 was 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 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.
"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 masters' orders. But in Diaspar, Man himself had lost the gift he had given to his slaves.
