<passage>:
The sand-thing was powerful, lonely and strange. No doubt it was a god—but who wasn't? Stinson lay still in the sand where he fell, gloating over the success "I've changed my mind. You will be welcomed." "Listen to that, will you?" Stinson said angrily. "Just listen! You of his arrival. coming here if the door was open." He touched the pencil-line scar behind his ear where the cylinder was set yourself up as a God for the webfoots. You get them eating out of "No!" Stinson shot back. "You've owned this planet for a million years. You have brooded here alone since before my people discovered fire, and in all those ages you never learned self-control. I can't your hand. Then what do you do? You throw a fit. Yes, a fit! Like an when it pleases him." Stinson relaxed. He'd had his say. Sybtl trembled beside him. A small mammal, round, furry, hopped by, sniffing inquisitively. Sybtl said, "Is the Sand God happy?" She shook her head. "No, he is not not like to be a God." "Stinson," the Sand God said. "You said I was adolescent. You are correct. Do you remember I told you how my people, the entire race, "But you continued to develop after...." "No." Stinson tried to imagine it. At first there must have been a single voice crying into a monstrous emptiness, "Mother, where are you? MOTHER! It stopped. It was about ten feet tall by three feet in diameter at the base. Then Stinson backed away again. It was changing. Now it became a sand blowing in the wind? A wind devil?" unutterably total void of time—FIVE HUNDRED THOUSAND YEARS! And a nine-year-old child brooding over an empty world. "I don't understand why your development stopped," Stinson said. "Nor do I. But perhaps ... well, I sense that I would continue, if you brought your people here. You have already taught me the value of Again Stinson felt the urge to run, or to use the cylinder to project himself somewhere else, but he said, "No!" very firmly to himself. He but it was composed only of grains of sand. There was no core, no The Sand God disappeared. Sybtl said "Is the Sand God angry again?" sand possibly have a nervous system? They saw him struggling. Two of the men came over and spoke to him in the musical language. "My name is Stinson," he said, pointing to himself. "I'm from the ceilinged cavern. "SBTL!" it said, "ZBTL ... XBTL ... zbtl." The men instantly prostrated themselves before him. The one who had poked Stinson with the stick rose, and handed it to him. Still angered, Stinson grasped it firmly, with half a notion to break it over his head. As he did so, a flash of blue fire sprang from it. The man disappeared. A small cloud of dust settled slowly to the floor. Disintegrated! Stinson's face drained pale, and suddenly, unaccountably, he was ashamed because he had no clothes. "I didn't mean to kill him!" he cried. "I was angry, and...." Useless. They could not understand. For all he knew, they might think speaking, and pointed to himself. "Me?" "Yes." "I am Stinson, of the planet Earth." another by a mere thought and a tiny instrument, yet you have done so. You deserted me out in the desert." "I deserted you?" Stinson cried angrily, "You tried to kill me!" "I was attempting communication. Why should I kill you?" He was silent a moment, looking at the people in the cavern. "Perhaps Stinson felt a mental shrug. "It is of no importance. When they arrived on this planet I attempted to explain that I was not a God, but the primitive is not deeply buried in them. They soon resorted to emotion "As for the webfoots," the wind devil, or Sand God, said, "I will "Destroy them?" Stinson asked, incredulously, "all these people? They have a right to live like any one else." the most basic structure of nature." The Sand God did not reply. The great bodiless, directionless voice was silent, and Stinson felt as if he had been taken from some high place When he looked back, the Sand God was gone. with hatred in their voices. He could not understand the words now. But he understood her. "They'll kill me!" she cried. Stinson pointed the disintegrating weapon at them and yelled. They dropped back. "We'll have to get outside," he told her. "This mob will soon get out of hand. Then the tube won't stop them. They will rush in. that we're in trouble together, we may as well introduce ourselves. My name is Stinson." "I am Sybtl," she said. "Syb-tl." He tried to imitate her musical pronunciation. "A very nice Stinson's bare feet were numb from walking on ice. Christ, he thought, what am I doing here, anyway? He glanced down at Sybtl and remembered the Sand God. It was blood red now. It pulsed violently. The great "What form of primitive stupidity are you practicing now? Leave, or they will kill you." Stinson shook his head. The Sand God pulsed more violently than before. Ice melted in a wide primitive logic long before it reached your level of development." "Yes," Stinson said, "and your race no longer exists." The Sand God became a sphere of blue flame. A wave of intense heat Sybtl shivered against his arm. "The Sand God is angry," she said. "My Kaatr got the tube-weapon. It was the only thing the Sand God didn't burn, that and the skirts. Then, when he had burned the ship, the Sand God went to the sixth planet and burned two of the largest cities, as a warning that no more of us must come here." Well, Stinson said to himself, that does it. We are better off on Earth. We can't fight a monster like him. Sybtl touched his arm. "Why did the Sand God come? He did not speak." "Don't worry. The Sand God travels without a ship, why shouldn't I?" no time, now, to warm cold feet or dwell on the vagaries of Sand Gods. attack. "They will not find us...." A high-pitched keening burst suddenly around them. Stinson knew they "The Sand God," Sybtl said. "Sometimes he plays among the clouds. He angry?" "The Sand God isn't doing this," Stinson said. "It's only a storm." She covered his lips with her fingers. "Don't say that. He may hear you and be more angry." understand. The Sand God is terrible, even when he plays. See the Stinson had never been in a sand storm before, even on Earth. He could not breathe. He could not see. Bullets of sand stung his skin. Bullets of sand shot into his eyes. Clouds of sand howled around him. He fell, and the wind rolled him over and over in the sand like a tumbleweed. put the lightning to shame. It bore down on the cave swiftly, purposefully. Stinson prepared himself to leave. In spite of his desire to protect Sybtl, it was useless to get himself killed when he was powerless to help her. But at the last moment it veered off. "Fiend!" Stinson screamed the word, vaguely marvelling at his own fury. "The Sand God is tired," Sybtl said. "He is not angry now. I'm glad. "Earthman," the Sand God said, as if he were about to make a statement. Stinson ignored him. He glanced down at Sybtl, who sensed that this was a time for good-bys. He thought, perhaps I can stay here alone with her. The webfoots might find us, or the Sand God might destroy us in
