Beyond the Fall of Night

by Arthur C. Clarke

  "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.

  The Empire had lasted for at least a billion years. It must have known many crises, perhaps even wars, but all these were lost in the sweep of great races moving together toward maturity.

  "We can be proud," continued Rorden, "of the part our ancestors played in this story. Even when they had reached their cultural plateau, they lost none of their initiative. We deal now with conjecture rather than proven fact, but it seems certain that the experiments which were at once the Empire's downfall and its crowning glory were inspired and directed by Man.

  "The philosophy underlying these experiments appears to have been this. Contact with other species had shown Man how profoundly a race's world-picture depended upon its physical body and the sense organs with which it was equipped. It was argued that a true picture of the Universe could be attained, if at all, only by a mind which was free from such physical limitations—a pure mentality, in fact. This idea was common among most very ancient religions and was believed by many to be the goal of evolution.

  "Largely as a result of the experience gained in his own regeneration, Man suggested that the creation of such beings should be attempted. It was the greatest challenge ever thrown out to intelligence in the Universe, and after centuries of debate it was accepted. All the races of the Galaxy joined together in its fulfillment.

  "Half a billion years were to separate the dream from the reality.

  Civilizations were to rise and fall, again and yet again the age-long toil of worlds was to be lost, but the goal was never forgotten. One day we may know the full story of this, the greatest sustained effort in all history. Today we only know that its ending was a disaster that almost wrecked the Galaxy.

  "Into this period Vanamonde's mind refuses to go. There is a narrow region of time which is blocked to him; but only, we believe, by his own fears. At its beginning we can see the Empire at the summit of its glory, taut with the expectation of coming success. At its end, only a few thousand years later, the Empire is shattered and the stars themselves are dimmed as though drained of their power. Over the Galaxy hangs a pall of fear, a fear with which is linked the name 'the Mad Mind.'

  "What must have happened in that short period is not hard to guess. The pure mentality had been created, but it was either insane or, as seems more likely from other sources, was implacably hostile to matter. For centuries it ravaged the Universe until brought under con
trol by forces of which we cannot guess. Whatever weapon the Empire used in its extremity squandered the resources of the stars: from the memories of that conflict spring some, though not all, of the legends of the Invaders. But of this I shall presently say more.

  "The Mad Mind could not be destroyed, for it was immortal. It was driven to the edge of the Galaxy and there imprisoned in a way we do not understand. Its prison was a strange artificial star known as the Black Sun, and there it remains to this day. When the Black Sun dies, it will be free again. How far in the future that day lies there is no way of telling."

  Alvin glanced quickly around the great room, which had become utterly silent. The councillors, for the most part, sat rigid in their seats, staring at Rorden with a trancelike immobility. Even to Alvin, who had already heard the story in fragments, Rorden's narrative still had the excitement of a newly unfolding drama. To the councillors, the impact of his revelations must be overwhelming.

  Rorden was speaking again in a quiet, more subdued voice as he described the last days of the Empire. This was the age, Alvin had decided, in which he would have liked to live. There had been adventure then, and a superb and dauntless courage—the courage that can snatch victory from the teeth of disaster.

  "Though the Galaxy had been laid waste by the Mad Mind, the resources of the Empire were still enormous, and its spirit was unbroken. With a courage at which we can only marvel, the great experiment was resumed and a search made for the flaw that had caused the catastrophe. There were now, of course, many who opposed the work and predicted further disasters, but they were overruled. The project went ahead and, with the knowledge so bitterly gained, this time it succeeded.

  "The new race that was born had a potential intellect that could not even be measured. But it was completely infantile: we do not know if this was expected by its creators, but it seems likely that they knew it to be inevitable. Millions of years would be needed before it reached maturity, and nothing could be done to hasten the process. Vanamonde was the first of these minds: there must be others elsewhere in the Galaxy, but we believe that only a very few were created, for Vanamonde has never encountered any of his fellows.

  "The creation of the pure mentalities was the greatest achievement of Galactic civilization: in it Man played a major and perhaps a dominant part. I have made no reference to Earth itself, for its story is too small a thread to be traced in the great tapestry. Since it had always been drained of its most adventurous spirits our planet had inevitably become somewhat conservative, and in the end it opposed the scientists who created Vanamonde. Certainly it played no part at all in the final act.

  "The work of the Empire was now finished: the men of that age looked round at the stars they had ravaged in their desperate peril, and they made the decision that might have been expected. They would leave the Universe to Vanamonde.

  "The choice was not hard to make, for the Empire had now made the first contacts with a very great and very strange civilization far around the curve of the Cosmos. This civilization, if the hints we can gather are correct, had evolved on the purely physical plane further than had been believed possible. There were, it seemed, more solutions than one to the problem of ultimate intelligence. But this we can only guess: all we know for certain is that within a very short period of time our ancestors and their fellow races have gone upon a journey which we cannot follow. Vanamonde's thoughts seem bounded by the confines of the Galaxy, but through his mind we have watched the beginning of that great adventure—"

  A pale wraith of its former glory, the slowly turning wheel of the Galaxy hangs in nothingness. Throughout its length are the great empty rents which the Mad Mind has torn — wounds that in ages to come the drifting stars will fill. But they will never restore the splendor that has gone.

  Man is about to leave his Universe, as once he left his world. And not only Man, hut the thousand other races that have worked with him to make the Empire. They have gathered together, here at the edge of the Galaxy, with its whole thickness between them and the goal they will not reach for ages.

  The long line of fire strikes across the Universe, leaping from star to star. In a moment of time a thousand suns have died, feeding their energies to the dim and monstrous shape that has torn along the axis of the Galaxy and is now receding into the abyss. . . .

  "The Empire had now left the Universe, to meet its destiny elsewhere. When its heirs, the pure mentalities, have reached their full stature we believe it will return again. But that day must still lie far ahead.

  "This, in its outlines, is the story of Galactic civilization. Our own history, which we thought so important, is no more than a belated episode which we have not yet examined in detail. But it seems that many of the older, less adventurous races refused to leave their homes. Our direct ancestors were among them. Most of these races fell into decadence and are now extinct: our own world barely escaped the same fate. In the Transition Centuries—which really lasted for millions of years—the knowledge of the past was lost or else deliberately destroyed. The latter seems more probable: we believe that Man sank into a superstitious barbarism during which he distorted history to remove his sense of impotence and failure. The legend of the Invaders is certainly false, and the Battle of Shalmirane is a myth. True, Shalmirane exists, and was one of the greatest weapons ever forged—but it was used against no intelligent enemy. Once the Earth had a single giant satellite, the Moon. When it began to fall, Shalmirane was built to destroy it. Around that destruction have been woven the legends you all know, and there are many such."

  Rorden paused, and smiled a little ruefully.

  "There are other paradoxes that have not yet been resolved, but the problem is one for the psychologist rather than the historian. Even my records cannot be wholly trusted, and bear clear evidence of tampering in the very remote past.

  "Only Diaspar and Lys survived the period of decadence—Diaspar thanks to the perfection of its machines, Lys owing to its partial isolation and the unusual intellectual powers of its people. But both cultures, even when they had struggled back to their former level, were distorted by the fears and myths they had inherited.

  "Those fears need haunt us no longer. All down the ages, we have now discovered, there were men who rebelled against them and maintained a tenuous link between Diaspar and Lys. Now the last barriers can be swept aside and our two races can move together into the future—whatever it may bring."

  "I wonder what Yarlan Zey would think of this?" said Rorden thoughtfully. "I doubt if he would approve."

  The Park had changed considerably, so far very much for the worse. But when the rubble had been cleared away, the road to Lys would be open for all to follow.

  "I don't know," Alvin replied. "Though he closed the moving ways, he didn't destroy them as he might very well have done. One day we must discover the whole story behind the Park—and behind Alaine of Lyndar."

  "I'm afraid these things will have to wait," said Rorden, "until more important problems have been settled. In any case, I can picture Alaine's mind rather well: once we must have had a good deal in common."

  They walked in silence for a few hundred yards, following the edge of the great excavation. The Tomb of Yarlan Zey was now poised on the brink of a chasm, at the bottom of which scores of robots were working furiously.

  "By the way," said Alvin abruptly, "did you know that Jeserac is staying in Lys? Jeserac, of all people! He likes it there and won't come back. Of course, that will leave a vacancy on the Council."

  "So it will," replied Rorden, as if he had never given the matter any thought. A short time ago he could have imagined very few things more unlikely than a seat on the Council; now it was probably only a matter of time. There would, he reflected, be a good many other resignations in the near future. Several of the older councillors had found themselves unable to face the new problems pouring upon them.

  They were now moving up the slope to the Tomb, through the long avenue of eternal trees. At its e
nd, the avenue was blocked by Alvin's ship, looking strangely out of place in these familiar surroundings.

  "There," said Rorden suddenly, "is the greatest mystery of all. Who was the Master? Where did he get this ship and the three robots?"

  "I've been thinking about that," answered Theon. "We know that he came from the Seven Suns, and there might have been a fairly high culture there when civilization on Earth was at its lowest. The ship itself is obviously the work of the Empire.

  "I believe that the Master was escaping from his own people. Perhaps he had ideas with which they didn't agree: he was a philosopher, and a rather remarkable one. He found our ancestors friendly but superstitious and tried to educate them, but they misunderstood and distorted his teachings. The Great Ones were no more than the men of the Empire—only it wasn't Earth they had left, but the Universe itself. The Master's disciples didn't understand or didn't believe this, and all their mythology and ritual was founded on that false premise. One day I intend to go into the Master's history and find why he tried to conceal his past. I think it will be a very interesting story."

  "We've a good deal to thank him for," said Rorden as they entered the ship. "Without him we would never have learned the truth about the past."

  "I'm not so sure," said Alvin. "Sooner or later Vanamonde would have discovered us. And I believe there may be other ships hidden on Earth: one day I mean to find them."

  The city was now too distant to be recognized as the work of Man, and the curve of the planet was becoming visible. In a little while they could see the line of twilight, thousands of miles away on its never-ending march across the desert. Above and around were the stars, still brilliant for all the glory they had lost.

  For a long time Rorden stared at the desolate panorama he had never seen before. He felt a sudden contemptuous anger for the men of the past who had let Earth's beauty die through their own neglect. If one of Alvin's dreams came true, and the great transmutation plants still existed, it would not be many centuries before the oceans rolled again.
