“It’s strange,” he said, “but until I lost my temper I never really understood what I wanted to do. Whether they like it or not, I’m going to break down the wall between Diaspar and Lys. But that can wait: it’s no longer so important now.”
Rorden felt a little alarmed.
“What do you mean?” he asked anxiously. For the first time he noticed that only one of the robots was with them on the parapet. “Where’s the second machine?”
Slowly Alvin raised his arm and pointed out across the desert, towards the broken hills and the long line of sand dunes, crisscrossed like frozen waves. Far away, Rorden could see the unmistakable gleam of sunlight upon metal.
“We’ve been waiting for you,” said Alvin quietly. “As soon as I left the Council, I went straight to the robots. Whatever happened, I was going to make sure that no one took them away before I’d learnt all they could teach me. It didn’t take long, for they’re not very intelligent and knew less than I’d hoped. But I have found the secret of the Master.” He paused for a moment, then pointed again at the almost invisible robot. “Watch!”
The glistening speck soared away from the desert and came to rest perhaps a thousand feet above the ground. At first, not knowing what to expect, Rorden could see no other 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 Rorden was beyond surprise or fear when the great sand dunes began to slide apart. Beneath the desert something was stirring like a giant awaking from its sleep, and presently there came to Rorden’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 the jagged wound torn across the face of the desert. But Rorden and Alvin still kept their eyes fixed steadfastly upon the open sky, which a little while ago had held only the waiting robot. What Alvin was thinking, Rorden could scarcely imagine. At last he knew what the boy had meant when he had said that nothing else was very important now. The great city behind them and the greater desert before, the timidity of the Council and the pride of Lys-all these seemed trivial matters now.
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 Rorden watched, it slowly turned towards 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.
“I still do not know who the Master was, or why he came to Earth. The robot gives me the impression that he landed secretly and hid his ship where it could be easily found if he ever needed it again. In all the world there could have been no better hiding place than the Port of Diaspar, which now lies beneath those sands and which even in his age must have been utterly deserted. He may have lived for a while in Diaspar before he went to Shahnirane: the road 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.”
The ship was now very close, as the controlling robot guided it towards the parapet. Rorden 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.
Suddenly they were spattered with dirt as a section of the hull opened outwards, and Rorden caught a glimpse of a small, bare room with a second door at its far end. The ship was now hanging only a foot away from the parapet, which it had approached very cautiously like a sensitive, living thing. Rorden had backed away from it as if he were afraid, which indeed was very near the truth. To him the ship symbolized all the terror and mystery of the Universe, and evoked as could no other object the racial fears which for so long had paralyzed the will of the human race. Looking at his friend, Alvin knew very well the thoughts that were passing through his brain. For almost the first time he reah’zed that there were forces in men’s minds over which they had no control, and that the Council was deserving of pity rather than contempt.
In utter silence, the ship drew away from the tower. It was strange, Rorden thought, that for the second time in his life he had said good-bye to Alvin. The little, closed world of Diaspar knew only one farewell, and that was for eternity.
The ship was now only a dark stain against the sky, and of a sudden Rorden 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 had ever made-the long-drawn thunder of air falling, mile after mile, into a tunnel drilled suddenly across the sky.
Even when the last echoes had died away into the desert, Rorden never moved. He was thinking of the boy who had gone-wondering, as he had so often done, if he would ever understand that aloof and baffling mind. Alvin would never grow up: to him the whole Universe was a plaything, a puzzle to be unravelled 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 still Rorden waited, conquering his fears, and presently for the first time in his life he saw the stars.
Even in Diaspar, Alvin had never seen such luxury as that which lay before him when the inner door of the airlock slid aside. At first he did not understand its implications: then he began to wonder, rather uneasily, how long this tiny world might be upon its journeying between the stars. There were no controls of any kind, but the large, oval screen which completely covered the far wall would have shown that this was no ordinary room. Ranged in a half-circle before it were three low couches: the rest of the cabin was occupied by two tables, a number of most inviting chairs, and many curious devices which for the moment Alvin could not identify.
When he had made himself comfortable in front of the screen, he looked around for the robots. To his surprise, they had disappeared: then he located them, neatly stowed away in recesses high up beneath the curved ceiling. Their action had been so completely natural that Alvin knew at once the purpose for which they had been intended. He remembered the Master Robots: these were the Interpreters, without which no untrained human mind could control a machine as complex as a spaceship. They had brought the Master to Earth and then, as his servants, followed him into Lys. Now they were ready, as if the intervening eons had never been, to carry out their old duties once again.
Alvin threw them 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 wondered if the ship itself moved as the picture changed, but could think of no way of discovering this. He 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 never thought of this, and when it did occur to him the machine was already moving across the desert at a tremendous speed. He shrugged his shoulders, thankfully accepting what he could not understand.
