Eccentric or not, they had minds he could respect. To him the thoughts of Vanamonde were as meaningless as a thousand voices shouting together in some vast, echoing cave. Yet the men of Lys could disentangle them, could record them to be analyzed at leisure. Already the structure of the past, which had once seemed lost forever, was becoming faintly visible. And it was so strange and unexpected that it appeared to bear no resemblance at all to the history that Rorden had always believed.

             In a few months he would present his first report to Diaspar.

             Though its contents were still uncertain, he knew that it would end forever the sterile isolation of his race. The barriers between Lys and Diaspar would vanish when their origin was understood, and the mingling of the two great cultures would invigorate mankind for ages to come. Yes even this now seemed no more than a minor by-product of the great research that was just beginning. If what Vanamonde had hinted was indeed true, Man's horizons must soon embrace not merely the Earth, but must enfold the stars and reach out to the Galaxies beyond. But of these further vistas it was still too early to be sure.

             Calitrax, chief historian of Lys, met them at the little jetty. He was a tall, slightly stooping man, and Rorden wondered how, without the help of the Master Associators, he had ever managed to learn so much in his short life. It did not occur to him that the very absence of such machines was the reason for the wonderful memories he had met in Grevarn.

             They walked together beside one of the innumerable canals that made life in the village so hazardous to strangers. Calitrax seemed a little preoccupied, and Rorden knew that part of his mind was still with Vanamonde.

             "Have you settled your date-fixing procedure yet?" asked Rorden presently, feeling somewhat neglected.

             Calitrax remembered his duties as host and broke contact with obvious reluctance.

             "Yes," he said. "It had to be the astronomical method. We think it's accurate to ten thousand years, even back to the Dawn Ages. It could be even better, but that's good enough to mark out the main epochs."

             "What about the Invaders? Has Bensor located them?"

             "No: he made one attempt but it's hopeless to look for any isolated period. What we're doing now is to go back to the beginning of history and then take cross-sections at regular intervals. We'll link them together by guesswork until we can fill in the details. If only Vanamonde could interpret what he sees! As it is we have to work through masses of irrelevant material."

             "I wonder what he thinks about the whole affair: it must all be rather puzzling to him."

             "Yes, I suppose it must. But he's very docile and friendly, and I think he's happy, if one can use that word. So Theon believes, and they seem to have a curious sort of affinity. Ah, here's Bensor with the latest ten million years of history. I'll leave you in his hands."

             The Council chamber had altered little since Alvin's last visit, for the seldom-used projection equipment was so inconspicuous that one could easily have overlooked it. There were two empty chairs along the great table: one, he knew, was Jeserac's. But though he was in Lys, Jeserac would be watching this meeting, as would almost all the world.

             If Rorden recalled their last appearance in this room, he did not care to mention it. But the councillors certainly remembered, as Alvin could tell by the ambiguous glances he received. He wondered what they would be thinking when they had heard Rorden's story. Already, in a few months, the present had changed out of all recognition—and now they were going to lose the past.

             Rorden began to speak. The great ways of Diaspar would be empty of traffic: the city would be hushed as Alvin had known it only once before in his life. It was waiting, waiting for the veil of the past to be lifted again after—if Calitrax was right—more than fifteen hundred million years.

             Very briefly, Rorden ran through the accepted history of the race—the history that both Diaspar and Lys had always believed beyond question. He spoke of the unknown peoples of the Dawn Civilizations, who had left behind them nothing but a handful of great names and the fading legends of the Empire. Even at the beginning, so the story went, Man had desired the stars and at last attained them. For millions of years he had expanded across the Galaxy, gathering system after system beneath his sway. Then, out of the darkness beyond the rim of the universe, the Invaders had struck and wrenched from him all that he had won.

             The retreat to the solar system had been bitter and must have lasted many ages. Earth itself was barely saved by the fabulous battles that raged round Shalmirane. When all was over, Man was left with only his memories and the world on which he had been born.

             Rorden paused: he looked round the great room and smiled slightly as his eyes met Alvin's.

             "So much for the tales we have believed since our records began. I must tell you now that they are false—false in every detail— so false that even now we have not fully reconciled them with the truth. "

             He waited for the full meaning of his words to strike home. Then, speaking slowly and carefully, but after the first few minutes never consulting his notes, he gave the city the knowledge that had been won from the mind of Vanamonde.

             It was not even true that Man had reached the stars. The whole of his little empire was bounded by the orbit of Persephone, for interstellar space proved a barrier beyond his power to cross. His entire civilization was huddled round the sun, and was still very young when—the stars reached him.

             The impact must have been shattering. Despite his failures, Man had never doubted that one day he would conquer the deeps of space. He believed too that if the Universe held his equals, it did not hold his superiors. Now he knew that both beliefs were wrong, and that out among the stars were minds far greater than his own. For many centuries, first in the ships of other races and later in machines built with borrowed knowledge, Man had explored the Galaxy. Everywhere he found cultures he could understand but could not match, and here and there he encountered minds which would soon have passed altogether beyond his comprehension.

             The shock was tremendous, but it proved the making of the race. Sadder and infinitely wiser, Man had returned to the solar system to brood upon the knowledge he had gained. He would accept the challenge, and slowly he evolved a plan which gave hope for the future.

             Once, the physical sciences had been Man's greatest interest. Now he turned even more fiercely to genetics and the study of the mind. Whatever the cost, he would drive himself to the limits of his evolution.

             The great experiment had consumed the entire energies of the race for millions of years. All that striving, all that sacrifice and toil, became only a handful of words in Rorden's narrative. It had brought Man his greatest victories. He had banished disease: he could live forever if he wished, and in mastering telepathy he had bent the most subtle of all powers to his will.

             He was ready to go out again, relying upon his own resources, into the great spaces of the Galaxy. He would meet as an equal the races of the worlds from which he had once turned aside. And he would play his full part in the story of the Universe.

             These things he did. From this age, perhaps the most spacious in all history, came the legends of the Empire. It had been an Empire of many races, but this had been forgotten in the drama, too tremendous for tragedy, in which it had come to its end.
