The survivors must be something else—capacities undeveloped by our science—after us the end of man, the beginning.... But those of us who chose to die were right." The tide of hate and sick desire rose up to drown all coherence. The Ryzga made a savage, wholly futile effort to lift the weapon in his with the Ryzgas themselves, who slept within, ready to wake and beyond the conqueror of the Ryzgas?" felt a wave of tenderness and bitterness. For him she had come to this. For the flame that had sprung between them at the Truce of New Grass, she had challenged the feud of their peoples and had left her home, to follow him. Now, if her father and his kinsmen overtook them, it would be death for Var, and for Neena living shame. Which of the two was worse cost. They hoarded their strength, helping one another one alone might never have won through. watch on the Ryzga mountain, as a part of the oldest legends of their Warming to the old man now, Var sketched his and Neena's history very long, I'm sure, I would have performed some deed which Groz would recognize as a worthy exploit, and would thus have healed the feud "And what will you do now?" to follow us." are doing. That is the second part of the law the First Watcher made: to guard lest the unwary and the ignorant should bring harm on themselves and on all men." "We know the stories," Var said brusquely. "In the hollow heart of their mountain the Ryzgas sleep, as they chose to do when their world Ryzgas will come forth." "The Ryzgas also were men," said the Watcher. "But they were such a race as the world has not seen before or since.

They were great and evil as no other people has been, because they wanted the stars. "Because of them we must build with dreams instead of iron, and our only fire is that of the Sun, and even now, two thousand years later, the Earth is still slowly recovering from the pangs and poison of that age. that survived when the Ryzgas' world went down in flame and thunder. "In the last generation of their power the Ryzgas knew by their science that the race of man would endure them no longer. They made ready their weapons, they mined the cities and the factories for destruction, making sure that their works and their knowledge would perish with them. Meanwhile they redoubled the yoke and the punishments, hastening the completion of the last of the starships. "From the memories that the old Watchers have left here, and from the Along lightless streets, half choked with rubble and with the dead, poured a mad, hating horde. The recurrent flashes lit scarred faces, the Ryzgas' might had been forged, eyes that stared white and half hope of new life on a world gutted and smoldering from the fulfilment of the Ryzgas' dream, without slogans other than a cry for blood. Before them death waited around the citadel where the masters still They had never seen its like, but they knew. It was the last starship, citadel. The hordes ran and shrieked again toward the central inferno, "Some of the Ryzgas took flight to the stars, and some perished on Earth. But there was a group of them who believed that their time to their deathless and lifeless sentinels round them, to wait till someone "I have told you the story you know, and have shown you a glimpse of the old time, because I must make sure that you do not approach the mountain in ignorance. Our world is unwise and sometimes evil, full of arrogance, folly, and passion that are in the nature of man. Yet it is a happy world, compared to that the Ryzgas made and will make again." that sleep was for infants and the aged, but his intention sank and rested, your minds are clear. Do you still mean to go on to the Ryzga Not looking at the Watcher, Var muttered unsteadily, "We have no the morning sun, but the mountain of the Ryzgas drank in the light and They thought, in the warm intimacy of unreserved understanding: " It would work: I-you would make the sacrifice of shame and mockery—yet these can be borne—that I-you might be saved from death—which is alone irreparable.... But to become little had the Ryzgas feared those who might assail them in their sleep. had passed through to light up the depths beyond. For within the Var and Neena turned. Far out in the sea of fog, on a dream bridge that too far to discern the rage that must contort his features, but the thought he hurled at them was a soundless bellow: "Young fools! I've caught you now!" potential that seemed to whisper had saved them from death in traps like this. But as yet the way was not mechanical servitors of the Ryzgas woke one by one and began to make ready, while their masters yet slept, for the moment of rebirth that then a directed thought, echoing and ghostly in the confinement of the " Stop! —before you go too far!" knew with finality that the other's stubbornness matched his own—that neither would yield, though the mountain above them and the world outside should crumble to ruin around them. "Follow us, then!" the death-cries of a billion slaves, the despair of all flesh and blood last. And the Ryzga too stood motionless, looking down at them. not wholly roused from his two millenia of slumber. But the Ryzga's manner and his mind radiated a consciousness of power, a pride and assurance of self that smote them like a numbing blow. With a new shock, Var realized that the Ryzga's thoughts were quite interlopers with the dispassionate gaze of a scientist examining a new, initially postulated but this will do. The pessimists were mistaken. We can begin again." Then, startlingly super-imposed on the cool progression of logical thought, came a wave of raw emotion, devastating in its force. It was a lustful image of a world once more obedient, crawling, laboring to do the Ryzgas' will— the driving will they had sensed a moment earlier. It was a sick man's face. The Ryzga's final thought clicked into place: Ryzga froze, teetering off balance and almost falling, as a numbing grip the Ryzga's frantic eyes. They glared back at him with such hatred and such evil that for an instant he almost faltered. But the Ryzga's misdirected and unavailing as those of a child who has not learned to wrestle with the mind. monster into the Ryzga's way—a mere child's bogey out of a fairy tale—the Ryzga had not recognized it as such, but had taken it for a world, Ryzga! In two thousand built so many machines, such complicated arrangements of matter and energy to do simple tasks—it was because you knew no other way."
