Alvin was disappointed-disappointed and annoyed. Rut he was young, and his opponent was old and tired. He began again to go through the argument, shifting his attack and pressing home each advantage. And now for the first time Theon saw an Alvin he had never suspected before-a personality, indeed, that was surprising Alvin himself. The men of the Dawn Ages had never let obstacles bar their way for long, and the will-power and determination that had been their heritage had not yet passed from Earth. Even as a child Alvin had withstood the forces seeking to mould him to the pattern of Diaspar. He was older now, and against him was not the greatest city of the world but only an aged man who sought nothing but rest, and would surely find that soon.

MASTER OF THE ROBOT

The evening was far advanced when the ground-car slid silently through the last screen of trees and came to rest in the great glade of Airlee. The argument, which had lasted most of the journey, had now died away and peace had been restored. They had never quite come to blows, perhaps because the odds were so unequal. Theon had only Krif to support him, but Alvin could call upon the argus-eyed, many-tentacled machine he still regarded so lovingly.

Theon had not minced his words. He had called his friend a bully and had told Alvin that he should be thoroughly ashamed of himself. But Alvin had only laughed and continued to play with his new toy. He did not know how the transfer had been effected, but he alone could control the robot now, could speak with its voice and see through its eyes. It would obey no one else in all the world.

Seranis was waiting for them in a surprising room which seemed to have no ceiling, though Alvin knew that there was a floor above it. She seemed to be worried and more uncertain than he had ever seen her before, and he remembered the choice that might soon lie before him. Until now he had almost forgotten it. He had believed that, somehow, the Council would resolve the difficulty. Now he realized that its decision might not be to his liking.

The voice of Seranis was troubled when she began to speak, and from her occasional pauses Alvin could tell that she was repeating words already rehearsed.

“Alvin,” she began, “there are many things I did not tell you before, but which you must learn now if you are to understand our actions.

“You know one of the reasons for the isolation of our two races. The fear of the Invaders, that dark shadow in the depths of every human mind, turned your people against the world and made them lose themselves in their own dreams. Here in Lys that fear has never been so great, although we bore the burden of the attack. We had a better reason for our actions, and what we did, we did with open eyes.

“Long ago, Alvin, men sought immortality and at last achieved it. They forgot that a world which had banished death must also banish birth. The power to extend his life indefinitely brought contentment to the individual but stagnation to the race. You once told me that you were the only child to be born in Diaspar for seven thousand years-but you have seen how many children we have here in Airlee. Ages ago we sacrificed our immortality, but Diaspar still follows the false dream. That is why our ways parted-and why they must never meet again.”
