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 control 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."
