Earth did not. But Alvin did.

The room was dark save for one glowing wall, upon which the tides of color ebbed and flowed as Alvin wrestled with his dreams. Part of the pattern satisfied him; he had fallen in love with the soaring lines of the mountains as they leaped out of the sea. There was a power and pride about those ascending curves; he had studied them for a long time, and then fed them into the memory unit of the visualizes, where they would be preserved while he experimented with the rest of the picture. Yet something was eluding him, though what it was he did not know. Again and again he had tried to fill in the blank spaces, while the instrument read the shifting patterns in his mind and materialized them upon the wall. It was no good. The lines were blurred and uncertain, the colors muddy and dull. If the artist did not know his goal, even the most miraculous of tools could not find it for him.
Alvin canceled his unsatisfactory scribblings and stared morosely at the three-quarters-empty rectangle he had been trying to fill with beauty. On a sudden impulse, he doubled the size of the existing design and shifted it to the center of the frame. No-that was a lazy way out, and the balance was all wrong. Worse still, the change of scale had revealed the defects in his construction, the lack of certainty in those atfirst-sight confident lines. He would have to start all over again.
«Total erasure,» he ordered the machine. The blue of the sea faded; the mountains dissolved like mist, until only the blank wall remained. They were as if they had never beenas if they were lost in the limbo that had taken all Earth’s seas and mountains ages before Alvin was born.
The light came flooding back into the room and the luminous rectangle upon which Alvin had projected his dreams merged into its surroundings, to become one with the other walls. But were they walls? To anyone who had never seen such a place before, this was a very peculiar room indeed. It was utterly featureless and completely devoid of furniture, so that it seemed as if Alvin stood at the center of a sphere. No visible dividing lines separated walls from floor or ceiling. There was nothing on which the eye could focus; the space enclosing Alvin might have been ten feet or ten miles across, for all that the sense of vision could have told. It would have been hard to resist the temptation to walk forward, hands outstretched, to discover the physical limits of this extraordinary place.
Yet such rooms had been «home» to most of the human race for the greater part of its history. Alvin had only to frame the appropriate thought, and the walls would become windows opening upon any part of the city he chose. Another wish, and machines which he had never seen would fill the chamber with the projected images of any articles of furniture he might need. Whether they were «real» or not was a problem that had bothered few men for the last billion years. Certainly they were no less real than that other impostor, solid matter, and when they were no longer required they could be returned to the phantom world of the city’s Memory Banks. Like everything else in Diaspar, they would never wear out-and they would never change, unless their stored patterns were canceled by a deliberate act of will.
Alvin had partly reconstructed his room when a persistent, bell-like chime sounded in his ear. He mentally framed the admission signal, and the wall upon which he had just been painting dissolved once more. As he bad expected, there stood his parents, with Jeserac a little behind them. The presence of his tutor meant that this was no ordinary family reunion -but he knew that already….
The illusion was perfect, and it was not lost when Eriston spoke. In reality, as Alvin was well aware, Eriston Etania, and Jeserac were all miles apart, for the builders of the city had conquered space as completely as they had subjugated time. Alvin was not even certain where his parents lived. among the multitudinous spires and intricate labyrinths of Diaspar, for they had both moved since he had last been physically in their presence.
Alvin,» began Eriston, «it is just twenty years since your mother and I first met you. You know what that means. Our guardianship is now ended, and you are free to do as you please.»
There was a trace–but merely a trace–of sadness in Brixton’s voice. There was considerably more relief, as if Eriston was glad that a state of affairs that had existed for some time in fact now had legal recognition. Alvin had anticipated his freedom by a good many years.
«I understand,» he answered. «I thank you for watching over me, and I will remember you in all my lives.» That was the formal response; he had heard it so often that all meaning had been leached away from it-it was merely a pattern of sounds with no particular significance. Yet «all my lives» was a strange expression, when one stopped to consider it. He knew vaguely what it meant; now the time had come for him to know exactly. There were many things in Diaspar which he did not understand, and which he would have to learn in the centuries that lay ahead of him.
For a moment it seemed as if Etania wished to speak. She raised one hand, disturbing the iridescent gossamer of her gown, then let it fall back to her side. Then she turned helplessly to Jeserac, and for the first time Alvin realized that his parents were worried. His memory swiftly sca
Jeserac, however, appeared to be in command of the situation. He gave an inquiring look at Eriston and Etania, satisfied himself that they had nothing more to say, and launched forth on the dissertation he had waited many years to make.
«Alvin,» he began, «for twenty years you have been my pupil, and I have done my best to teach you the ways of the city, and to lead you to the heritage which is yours. You have asked me many questions, and not all of them have I been able to answer. Some things you were not ready to learn, and some I did not know myself. Now your infancy is over, though your childhood is scarcely begun. It is still my duty to guide you, if you need my help. In two hundred years, Alvin , you may begin to know something of this city and a little of its history. Even I, who am nearing the end of this life, have seen less than a quarter of Diaspar, and perhaps less than a thousandth of its treasures.»
There was nothing so far that Alvin did not know, but there was no way of hurrying Jeserac. The old man looked steadfastly at him across the gulf of centuries, his words weighed down with the uncomputable wisdom acquired during a long lifetime’s contact with men and machines.
«Tell me, Alvin,» he said, «have you ever asked yourself where you were before you were born-before you found yourself facing Etania and Eriston at the Hall of Creation?»
«I assumed I was nowhere-that I was nothing but a pattern in the mind of the city, waiting to be created-like this.»
A low couch glimmered and thickened into reality beside Alvin. He sat down upon it and waited for Jeserac to continue.
«You are correct, of course,» came the reply. «But that is merely part of the answer-and a very small part indeed. Until now, you have met only children of your own age, and they have been ignorant of the truth. Soon they will remember, but you will not, so we must prepare you to face the facts.
For over a billion years, Alvin, the human race has lived in this city. Since the Galactic Empire fell, and the Invaders . went back to the stars, this has been our world. Outside the walls of Diaspar, there is nothing except the desert of which our legends speak.
