"I've changed my mind. You will be welcomed." "Listen to that, will you?" Stinson said angrily. "Just listen! You set yourself up as a God for the webfoots. You get them eating out of your hand. Then what do you do? You throw a fit. Yes, a fit! Like an adolescent. Worse." 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 happy. He is old, old, old. I can feel it. My people say that when one portion of this planet that suits you. Take the web-footed woman for your wife. Have children. I promise never to harm you in any way." "The webfoots?" "You and they shall share the planet." The Sand God disappeared. Sybtl said "Is the Sand God angry again?" "No, he is not angry." offender, spun him around and slapped his face. A cry of consternation rose from the group, echoing in the high ceilinged cavern. "SBTL!" it said, "ZBTL ... XBTL ... zbtl." The men instantly prostrated themselves before him. The one who had direction. It came from the ceiling, the floor, the walls, the steaming pool. It was in the language of the web-footed people it was in his own tongue. "No harm must come to this woman. The God with fingers on "I was attempting communication. Why should I kill you?" He was silent a moment, looking at the people in the cavern. "Perhaps because you feared I would become the God of these people in your place." 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 interested in you. You will bring your people, and live here." "I haven't decided. There are these web-footed people, who were hostile until they thought I was a God. They have destructive weapons. Also, I don't understand you. I see you as a cone of sand which keeps changing webfoots use is a toy by comparison. Our scientists found the ultimate nature of physical law. They learned to separate the mind from the body. Then my people set a date. Our entire race was determined to free God," she said, "to speak to my people again. Their fear of him does not last. When He is gone they will probably kill us." "As for the webfoots," the wind devil, or Sand God, said, "I will destroy them. You and your people will have the entire planet." "Destroy them?" Stinson asked, incredulously, "all these people? They When he looked back, the Sand God was gone. Instantly a new note rose in the cavern. The murmur of unmistakable mob fury ran over the webfoots. Several of the men approached the woman with hatred in their voices. He could not understand the words now. But he understood her. "They'll kill me!" she cried. had thoughtfully brought along from the cavern. He took it, and they ran down the slippery path leading away from the entrance. From the hiding place behind a large rock they watched, as several web-footed men emerged into the sunlight. They blinked, covered their eyes, and jabbered musically among themselves. One slipped and fell on the ice. "I am Sybtl," she said. "Syb-tl." He tried to imitate her musical pronunciation. "A very nice name." she is his chosen. Otherwise, why not let her die? You are a strange God." "Listen, Sybtl," he said desperately, "I am not a God and you are not my wife. Let's get that straight." "But...." and ran. He doubted the wisdom of keeping her with him. Alone, the webfoots were no match for him. He could travel instantly to any spot he chose. But with Sybtl it was another matter he was no better than depended on him. Anyway, he decided, pursuit was impossible. They left no tracks on the ice. They were safe, unless the webfoots possessed talents unknown to him. what am I doing here, anyway? He glanced down at Sybtl and remembered the webfoots. He stopped, tempted to use his cylinder and move to a warmer, less dangerous spot. The woman pulled on his arm. "We must hurry!" the Sand God. It was blood red now. It pulsed violently. The great voice burst forth. "Leave the woman!" it demanded angrily. "The webfoots are nearing your position." "I cannot leave her. She is helpless against them." drove them backward. "Earthman," the great voice said, "go back to your Earth. Take your inconsistencies with you. Do not come here again to infect my planet with your primitive ideas. The webfoots are not as intelligent as you, but they are sane. If you bring your people here, I shall destroy you all." the thunder of its passing shook the ground and echoed among the lonely hills. Sybtl shivered against his arm. "The Sand God is angry," she said. "My people tell how he was angry once before, when we first came here. He killed half of us and burned the ship that brought us. That is how 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 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." "He spoke to me." "I did not hear." mound of rock. Here they came to the creek again, which flowed into a small canyon. They climbed the canyon wall. Far away, small figures moved. The webfoots were on their trail. She drew him into a small cave. It was heated, like the great cavern, but held no walled pool nor mysterious lighting. But it was warm, and "They will not find us...." "But it is, don't you see? You give him powers he does not possess." Sybtl shook her head and stroked his face with her long, slim fingers. "Poor little God-with-fingers-on-his-feet," she said. "You do not understand. The Sand God is terrible, even when he plays. See the trembled. Sybtl moved closer, trembling also. "He never did this before," she said. "He never made the earth shake before." 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. Thunder rumbled distantly. Clouds disappeared. Stinson and Sybtl emerged from the cave. There was no longer a question of attack from the webfoots, the storm and throwing shadows and coaxing life out into the open again. Down in the canyon a bird sang, a lonely, cheerful twitter. "The Sand God is tired," Sybtl said. "He is not angry now. I'm glad. Perhaps he will let you stay." "No. Even if he allowed it, I couldn't stay. My people could never live 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 one of his fits, but it might be worth it. "Don't go," she said. "Not yet."
