other. Bacteria, gas and radiations had covered the Earth like a vast cloud. In the first days of that war, invincible secret weapon had succeeded secret weapon with almost monotonous regularity. And after the last hand had pushed the last button, the bombs, automatically guided and impelled, had continued to rain down. The unhappy Earth was a huge junkyard, without a living thing, plant or animal, from pole to pole. He had watched a good part of it. He had waited until he was fairly sure the last bomb had been dropped; then he had come down. Very clever of you, he thought bitterly, looking out the mouth of the cave at the lava plain his ship rested on, and at the twisted mountains behind it. You're a traitor—but who cares? He had been a captain in the Western Hemisphere Defense. Within two days of warfare, he had known what the end would be. Filling a cruiser with canned air, food and water, he had fled. In the confusion and destruction, he knew that he would never be missed; after a few days there was no one left to miss him. He had raced the big ship to the dark side of the Moon, and waited.

Landing on the Earth should have killed him, for the air itself was poisoned. He hadn't cared—and he had lived. He seemed to be immune to the various kinds of germs and radiations, or perhaps that was part of his new power. He certainly had encountered enough of both, skipping around the world in his ship, from the ruins of one city to another, across blasted valleys and plains, scorched mountains. He had found no life, but he did discover something. He could create. He realized the power on his third day on Earth. Wistfully, he had wished for a tree in the midst of the melted rock and metal; a tree had appeared. The rest of the day he experimented, and found that he could create anything that he had ever seen or heard about. Things he
