As he took leave of the Council, he wondered if they were surprised at his quiet acquiescence, his lack of indignation at the closing of the path to Lys. The proctors did not accompany him; he was no longer under observation, at least in so open a manner. Only Jeserac followed him out of the Council Chamber and into the colored, crowded streets.

  “Well, Alvin,” he said. “You were on your best behavior, but you cannot deceive me. What are you planning?”

  Alvin smiled.

  “I knew that you would suspect something; if you will come with me, I will show you why the subway to Lys is no longer important. And there is another experiment I want to try; it will not harm you, but you may not like it.”

  “Very well. I am still supposed to be your tutor, but it seems that the roles are now reversed. Where are you taking me?”

  “We are going to the Tower of Loranne, and I am going to show you the world outside Diaspar.”

  Jeserac paled, but he stood his ground. Then, as if not trusting himself with words, he gave a stiff little nod and followed Alvin out onto the smoothly gliding surface of the moving way.

  Jeserac showed no fear as they walked along the tunnel through which that cold wind blew forever into Diaspar. The tunnel had changed now; the stone grille that had blocked access to the outer world was gone. It served no structural purpose, and the Central Computer had removed it without comment at Alvin’s request. Later, it might instruct the monitors to remember the grille again and bring it back into existence. But for the moment the tunnel gaped unfenced and unguarded in the sheer outer wall of the city.

  Not until Jeserac had almost reached the end of the air shaft did he realize that the outer world was now upon him. He looked at the widening circle of sky, and his steps became more and more uncertain until they finally slowed to a halt. Alvin remembered how Alystra had turned and fled from this same spot, and he wondered if he could induce Jeserac to go any further.

  “I am only asking you to look,” he begged, “not to leave the city. Surely you can manage to do that!”

  In Airlee, during his brief stay, Alvin has seen a mother teaching her child to walk. He was irresistibly reminded of this as he coaxed Jeserac along the corridor, making encouraging remarks as his tutor advanced foot by reluctant foot. Jeserac, unlike Khedron, was no coward. He was prepared to fight against his compulsion, but it was a desperate struggle. Alvin was almost as exhausted as the older man by the time he had succeeded in getting Jeserac to a point where he could see the whole, uninterrupted sweep of the desert.

  Once there, the interest and strange beauty of the scene, so alien to all that Jeserac had ever known in this or any previous existence, seemed to overcome his fears. He was clearly fascinated by the immense vista of the rolling sand dunes and the far-off, ancient hills. It was late afternoon, and in a little while all this land would be visited by the night that never came to Diaspar.

  “I asked you to come here,” said Alvin, speaking quickly as if he could hardly control his impatience, “because I realize that you have earned more right than anyone to see where my travels have led me. I wanted you to see the desert, and I also want you to be a witness, so that the Council will know what I have done.

  “As I told the Council, I brought this robot home from Lys in the hope that the Central Computer would be able to break the block that has been imposed on its memories by the man known as the Master. By a trick which I still don’t fully understand, the Computer did that. Now I have access to all the memories in this machine, as well as to the special skills that had been designed into it. I’m going to use one of those skills now. Watch.”

  On a soundless order which Jeserac could only guess, the robot floated out of the tunnel entrance, picked up speed, and within seconds was no more than a distant metallic gleam in the sunlight. It was flying low over the desert, across the sand dunes that lay crisscrossed like frozen waves. Jeserac had the unmistakable impression that it was searching— though for what, he could not imagine.

  Then, abruptly, the glittering speck soared away from the desert and came to rest a thousand feet above the ground. At the same moment, Alvin gave an explosive sigh of satisfaction and relief. He glanced quickly at Jeserac, as if to say: “This is it!”

  At first, not knowing what to expect, Jeserac could see no change. Then, scarcely believing his eyes, he saw that a cloud of dust was slowly rising from the desert.

  Nothing is more terrible than movement where no movement should ever be again, but Jeserac was beyond surprise or fear as the sand dunes began to slide apart. Beneath the desert something was stirring like a giant awakening from its sleep, and presently there came to Jeserac’s ears the rumble of falling earth and the shriek of rock split asunder by irresistible force. Then, suddenly, a great geyser of sand erupted hundreds of feet into the air and the ground was hidden from sight.

  Slowly the dust began to settle back into a jagged wound torn across the face of the desert. But Jeserac and Alvin still kept their eyes fixed steadfastly upon the open sky, which a little while ago had held only the waiting robot. Now at last Jeserac knew why Alvin had seemed so indifferent to the decision of the Council, why he had shown no emotion when he was told that the subway to Lys had been closed.

  The covering of earth and rock could blur but could not conceal the proud lines of the ship still ascending from the riven desert. As Jeserac watched, it slowly turned toward them until it had foreshortened to a circle. Then, very leisurely, the circle started to expand.

  Alvin began to speak, rather quickly, as if the time were short.

  “This robot was designed to be the Master’s companion and servant— and, above all, the pilot of his ship. Before he came to Lys, he landed at the Port of Diaspar, which now lies out there beneath those sands. Even in his day, it must have been largely deserted; I think that the Master’s ship was one of the last ever to reach Earth. He lived for a while in Diaspar before he went to Shalmirane; the way must still have been open in those days. But he never needed the ship again, and all these ages it has been waiting out there beneath the sands. Like Diaspar itself, like this robot— like everything that the builders of the past considered really important— it was preserved by its own eternity circuits. As long as it had a source of power, it could never wear out or be destroyed; the image carried in its memory cells would never fade, and that image controlled its physical structure.”

  The ship was now very close, as the controlling robot guided it toward the tower. Jeserac could see that it was about a hundred feet long and sharply pointed at both ends. There appeared to be no windows or other openings, though the thick layer of earth made it impossible to be certain of this.

  Suddenly they were spattered with dirt as a section of the hull opened outward, and Jeserac caught a glimpse of a small, bare room with a second door at its far end. The ship was hanging only a foot away from the mouth of the air vent, which it had approached very cautiously like a sensitive, living thing.

  “Good-bye, Jeserac,” said Alvin. “I cannot go back into Diaspar to say farewell to my friends: please do that for me. Tell Eriston and Etania that I hope to return soon; if I do not, I am grateful for all that they did. And I am grateful to you, even though you may not approve of the way I have applied your lessons.

  “And as for the Council— tell it that a road that has once been opened cannot be closed again merely by passing a resolution.”

  The ship was now only a dark stain against the sky, and of a sudden Jeserac lost it altogether. He never saw its going, but presently there echoed down from the heavens the most awe-inspiring of all the sounds that Man has ever made— the long-drawn thunder of air falling, mile after mile, into a tunnel of vacuum drilled suddenly across the sky.

  Even when the last echoes had died away into the desert, Jeserac never moved. He was thinking of the boy who had gone— for to Jeserac, Alvin would always be a child, the only one to come into Diaspar since the cycle of birth and death had been broken, so long ago. Alvin would never
grow up; to him the whole Universe was a plaything, a puzzle to be unraveled for his own amusement. In his play he had now found the ultimate, deadly toy which might wreck what was left of human civilization— but whatever the outcome, to him it would still be a game.

  The sun was now low on the horizon, and a chill wind was blowing from the desert. But Jeserac still waited, conquering his fears; and presently for the first time in his life he saw the stars.

  CHAPTER

  18

  Even in Diaspar, Alvin had seldom seen such luxury as that which lay before him when the inner door of the air lock slid aside. Whatever else he had been, at least the Master was no ascetic. Not until some time later did it occur to Alvin that all this comfort might be no vain extravagance; this little world must have been the Master’s only home on many long journeys among the stars.

  There were no visible controls of any kind, but the large oval screen which completely covered the far wall showed that his was no ordinary room. Ranged in a half circle before it were three low couches; the rest of the cabin was occupied by two small tables and a number of padded chairs— some of them obviously not designed for human occupants.

  When he had made himself comfortable in front of the screen, Alvin looked around for the robot. To his surprise, it had disappeared; then he located it, neatly stowed away in a recess beneath the curved ceiling. It had brought the Master across space to Earth and then, as his servant, followed him into Lys. Now it was ready, as if the intervening aeons had never been, to carry out its old duties once again.

  Alvin threw it an experimental command, and the great screen shivered into life. Before him was the Tower of Loranne, curiously foreshortened and apparently lying on its side. Further trials gave him views of the sky, of the city, and of great expanses of desert. The definition was brilliantly, almost unnaturally, clear, although there seemed to be no actual magnification. Alvin experimented for a little while until he could obtain any view he wished; then he was ready to start.

  “Take me to Lys.” The command was a simple one, but how could the ship obey it when he himself had no idea of the direction? Alvin had not considered this, and when it did occur to him the machine was already moving across the desert at a tremendous speed. He shrugged his shoulders, accepting thankfully the fact that he now had servants wiser than himself.

  It was difficult to judge the scale of the picture racing up the screen, but many miles must be passing every minute. Not far from the city the color of the ground had changed abruptly to a dull gray, and Alvin knew that he was passing over the bed of one of the lost oceans. Once Diaspar must have been very near the sea, though there had never been any hint of this even in the most ancient records. Old though the city was, the oceans must have passed away long before its founding.

  Hundreds of miles later, the ground rose sharply and the desert returned. Once Alvin halted his ship above a curious pattern of intersecting lines, showing faintly through the blanket of sand. For a moment it puzzled him; then he realized that he was looking down upon the ruins of some forgotten city. He did not stay for long; it was heartbreaking to think that billions of men had left no other trace of their existence save these furrows in the sand.

  The smooth curve of the horizon was breaking up at last, crinkling into mountains that were beneath him almost as soon as they were glimpsed. The machine was slowing now, slowing and falling to earth in a great arc a hundred miles in length. And then below him was Lys, its forests and endless rivers forming a scene of such incomparable beauty that for a while he could go no further. To the east, the land was shadowed and the great lakes floated upon it like pools of darker night. But toward the sunset, the waters danced and sparkled with light, throwing back toward him such colors as he had never imagined.

  It was not difficult to locate Airlee— which was fortunate, for the robot could guide him no further. Alvin had expected this, and felt a little glad to have discovered some limits to its powers. It was unlikely that it would ever have heard of Airlee, so the position of the village would never have been stored in its memory cells.

  After a little experimenting, Alvin brought his ship to rest on the hillside that had given him his first glimpse of Lys. It was quite easy to control the machine; he had only to indicate his general desires and the robot attended to the details. It would, he imagined, ignore dangerous or impossible orders, though he had no intention of giving any if he could avoid it. Alvin was fairly certain that no one could have seen his arrival. He thought this rather important, for he had no desire to engage in mental combat with Seranis again. His plans were still somewhat vague, but he was running no risks until he had established friendly relations. The robot could act as his ambassador, while he remained safely in the ship.

  He met no one on the road to Airlee. It was strange to sit in the spaceship while his field of vision moved effortlessly along the familiar path, and the whispering of the forest sounded in his ears. As yet he was unable to identify himself fully with the robot, and the strain of controlling it was still considerable.

  It was nearly dark when he reached Airlee, and the little houses were floating in pools of light. Alvin kept to the shadows and had almost reached Seranis’s home before he was discovered. Suddenly there was an angry, high-pitched buzzing and his view was blocked by a flurry of wings. He recoiled involuntarily before the onslaught; then he realized what had happened. Krif was once again expressing his resentment of anything that flew without wings.

  Not wishing to hurt the beautiful but stupid creature, Alvin brought the robot to a halt and endured as best he could the blows that seemed to be raining upon him. Though he was sitting in comfort a mile away, he could not avoid flinching and was glad when Hilvar came out to investigate.

  At his master’s approach Kris departed, still buzzing balefully. In the silence that followed, Hilvar stood looking at the robot for a while. Then he smiled.

  “Hello, Alvin,” he said. “I’m glad you’ve come back. Or are you still in Diaspar?”

  Not for the first time, Alvin felt an envious admiration for the speed and precision of Hilvar’s mind.

  “No,” he said, wondering as he did so how clearly the robot echoed his voice. “I’m in Airlee, not very far away. But I’m staying here for the present.”

  Hilvar laughed.

  “I think that’s just as well. Seranis has forgiven you, but as for the Assembly— well, that is another matter. There is a conference going on here at the moment— the first we have ever had in Airlee.”

  “Do you mean,” asked Alvin, “that your Councilors have actually come here? With your telepathic powers, I should have thought that meetings weren’t necessary.”

  “They are rare, but there are times when they are felt desirable. I don’t know the exact nature of the crisis, but three Senators are already here and the rest are expected soon.”

  Alvin could not help smiling at the way in which events in Diaspar had been mirrored here. Wherever he went, he now seemed to be leaving a trail of consternation and alarm behind him.

  “I think it would be a good idea,” he said, “if I could talk to this Assembly of yours— as long as I can do so in safety.”

  “It would be safe for you to come here yourself,” said Hilvar, “if the Assembly promises not to try and take over your mind again. Otherwise, I should stay where you are. I’ll lead your robot to the Senators— they’ll be rather upset to see it.”

  Alvin felt that keen but treacherous sense of enjoyment and exhilaration as he followed Hilvar into the house. He was meeting the rulers of Lys on more equal terms now; though he felt no rancor against them, it was very pleasant to know that he was now master of the situation, and in command of powers which even yet he had not fully turned to account.

  The door of the conference room was locked, and it was some time before Hilvar could attract attention. The minds of the Senators, it seemed, were so completely engaged that it was difficult to break into their deliberations. Then the walls slid reluctantly as
ide, and Alvin moved his robot swiftly forward into the chamber.

  The three Senators froze in their seats as he floated toward them, but only the slightest flicker of surprise crossed Seranis’s face. Perhaps Hilvar had already sent her a warning, or perhaps she had expected that, sooner or later, Alvin would return.

  “Good evening,” he said politely, as if this vicarious entry were the most natural thing in the world. “I’ve decided to come back.”

  Their surprise certainly exceeded his expectations. One of the Senators, a young man with graying hair, was the first to recover.

  “How did you get here?” he gasped.

  The reason for his astonishment was obvious. Just as Diaspar had done, so Lys must also have put the subway out of action.

  “Why, I came here just as I did last time,” said Alvin, unable to resist amusing himself at their expense.

  Two of the Senators looked fixedly at the third, who spread his hands in a gesture of baffled resignation. Then the young man who had addressed him before spoke again.

  “Didn’t you have any— difficulty?” he asked.

  “None at all,” said Alvin, determined to increase their confusion. He saw that he had succeeded.

  “I’ve come back,” he continued, “under my own free will, and because I have some important news for you. However, in view of our previous disagreement I’m remaining out of sight for the moment. If I appear personally, will you promise not to try to restrict my movements again?”

  No one said anything for a while, and Alvin wondered what thoughts were being silently interchanged. Then Seranis spoke for them all.

  “We won’t attempt to control you again— though I don’t think we were very successful before.”
