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 grey, and Alvin knew that he was now 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 building.
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 on 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 would go no farther. To the east, the land was shadowed and the great lakes floated upon it like pools of darker night. But towards the sunset, the waters danced and sparkled with light, throwing back towards him such colors as he had never imagined.
It was not difficult to locate Airlee-which was fortunate, for the robots could guide him no farther. Alvin had expected this, and felt glad to have discovered some limits to their powers. After a little experimenting, he brought his ship to rest on the hillside which 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 robots attended to the details. They would, he imagined, probably ignore any dangerous or impossible orders, but he did not intend to try the experiment.
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 re-established friendly relations.
The discovery that the original robot would no longer obey him was a considerable shock. When he ordered it from its little compartment it refused to move but lay motionless, watching him dispassionately with its multiple eyes. To Alvin’s relief, the replica obeyed him instantly, but no amount of cajoling could make the prototype carry out even the simplest action. Alvin worried for some time before the explanation of the mutiny occurred to him. For all their wonderful skills, the robots were not very intelligent, and the events of the past hour must have been too much for the unfortunate machine. One by one it had seen all the Master’s orders defied-those orders which it had obeyed with such singleness of purpose for so many millions of years.
It was too late for regrets now, but Alvin was sorry he had made only a single duplicate. For the borrowed robot had become insane.
Alvin 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’ 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 did not approve of anything that flew without wings, and only Theon’s presence had prevented him from attacking the robot on earlier occasions. 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 Theon came out to investigate.

THE CRISIS
At his master’s approach Krif departed, still buzzing bale-fully. In the silence that followed Theon stood looking at the robot for a while. Then he smiled.
“I’m glad you’ve come back. Or are you still in Diaspar?”
Not for the first time Alvin felt a twinge of envy as he realized how much quicker Theon’s mind was than his own.
“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.”
Theon laughed heartily.
“I think that’s just as well,” he said. “Mother’s forgiven you, but the Central Council hasn’t. There’s a conference going on indoors now: I have to keep out of the way.”
“What are they talking about?”
“I’m not supposed to know, but they asked me all sorts of questions about you. I had to tell them what happened in Shalmirane.”
“That doesn’t matter very much,” replied Alvin. “A good many other things have happened since then. I’d like to have a talk with this Central Council of yours.”
“Oh, the whole Council isn’t here, naturally. But three of its members have been making enquiries ever since you left.”
Alvin smiled. He could well believe it: wherever he went now he seemed to be leaving a trail of consternation behind him.
The comfort and security of the spaceship gave him a confidence he had seldom known before, and he felt complete master of the situation as he followed Theon into the house. The door of the conference room was locked and it was some time before Theon could attract attention. Then the walls slid reluctantly apart, and Alvin moved his robot swiftly forward into the chamber.
The room was the familiar one in which he had had his last interview with Seranis. Overhead the stars were twinkling as if there were no ceiling or upper floor, and once again Alvin wondered how the illusion was achieved. The three councillors froze in their seats as he floated towards them, but only the slightest flicker of surprise crossed Seranis’ face.
“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 exceeded his expectations. One of the councillors, a young man with greying hair, was the first to recover.
“How did you get here?” he gasped.
Alvin thought it wise to evade the question: the way in which it was asked made him suspicious and he wondered if the underground transport system had been put out of action.
“Why, just as I did last time,” he lied.
Two of the councillors 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?”
“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, but 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 and restrict my movements again?”
No one said anything for a while and Alvin wondered what thoughts were being exchanged. Then Seranis spoke for them all.
“I imagine that there is little purpose in doing so. Di-aspar must know all about us by now.”
Alvin flushed slightly at the reproach in her voice.
“Yes, Diaspar knows,” he replied. “And Diaspar will have nothing to do with you. It wishes to avoid contamination with an inferior culture.”
