"I've decided not to bring my people here." " You of his arrival. adolescent. Worse." "Earthman, wait...." "No!" Stinson shot back. "You've owned this planet for a million climatic phenomena on earth practically non-existent. The cloud did not move, though, except to spin on its axis rapidly, emitting mammal, round, furry, hopped by, sniffing inquisitively. adults?" o'clock in the afternoon, if this had been Earth. Not a tree, nor a ?" A frenzied searching of the planet, the solar system, the galaxy. Then a returning to the planet. Empty.... Change. Buildings, roads, bridges weathering slowly. Such a race would have built of durable metal. Durable? Centuries, eons passed. Buildings crumbled to dust, dust blew away. Bridges eroded, fell, decomposed into basic elements. The shape of constellations changed. All trace of civilization passed except in the cavern of the heated pool. "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 illusion. life. There is a oneness, a bond that ties each living thing to every 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." was here to investigate, to determine if this planet was capable of nervous system. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? central place you could point to and say, here is the brain, or the When the symbols were repeated he pointed to each in turn, excitement first grains of sand, the realization of what was happening dawned with wall surrounding the pool was inscribed with intricate art work and indecipherable symbols. Life. Intelligence. The planet was inhabited. given cylinders, and who were now struggling for life against those who desired them. The unknown artist had been clever. From one angle they were animals, from another birds, from a third they were vaguely humanoid creatures, line was visible, yet he felt, or saw—he did not know which senses wondered, fleetingly, if a lethal instrument was in the statue. The cavern was crowded. These creatures were not only humanoid, but definitely human, although more slight of build than earth people. The only difference he could see at first sight was that they had webbed feet. All were dressed from the waist down only, in a shimmering skirt that sparkled as they moved. They walked with the grace of ballet dancers, moving about the plaza, conversing in a musical language with no meaning for Stinson. The men were dark-skinned, the women somewhat lighter, with long flowing hair, wide lips and a beauty that was utterly sensual. He was in chains! They were small chains, light weight, of a metal that the musical language. planet Earth." They looked at each other and jabbered some more. Useless. They could not understand. For all he knew, they might think This weapon was completely out of place in a culture such as this. Or was it? What did he know of these people? Very little. They were humanoid. They had exhibited human emotions of anger, fear and, that most human of all characteristics, curiosity. But up to now the tube and the chain was the only evidence of an advanced technology, unless lining the wall were evidences. There was a stirring among the crowd. An object like a pallet was breasts dipping slightly at each step. Her eyes held a language all their own, universal. She pressed her body against him and bore him to Incongruously, he thought of Benjamin back on earth, and all the others Those in the cavern looked at the woman with fear and respect. She about their activities. They did not hear. "Who are you?" "I do not understand how. You have a body, a physical body composed of atoms. It is impossible to move a physical body from one place to 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 rather than reason. It is of no importance." "I'd hardly call them primitive, with such weapons." "The tube is not of their technology. That is, they did not make it directly. These are the undesirables, the incorrigibles, the nonconformists from the sixth planet. I permit them here because it occupies my time, to watch them evolve." forgotten. You are a strange entity. You travel by a means even I cannot fully understand, yet you speak of time as if some event were about to take place. I believe you think of death. I see your physical body has deteriorated since yesterday. Your body will cease to exist, almost as soon as those of the sixth planet peoples. I am most interested in you. You will bring your people, and live here." don't understand you. I see you as a cone of sand which keeps changing color and configuration. Is it your body? Where do you come from? Is cavern, the heated pool, the statues, the inscriptions. Half a million years ago my people were as you. That is, they lived in physical bodies. Our technology surpassed any you have seen. The tube these 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 "I do not know. I alone exist. I have searched all the levels of time now on the pallet. The men had left her and stood in groups, talking, glancing at him, apparently free of their awe and fear already. 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." have a right to live like any one else." "Right? What is it—'right?' They are entities. They exist, therefore they always will. My people are the only entities who ever died. To kill the body is unimportant." is a scientific hypothesis. It has to do with what comes after physical entity, once existing, must not be harmed in any way. To do so changes the most basic structure of nature." hiding place behind a large rock they watched, as several web-footed men emerged into the sunlight. They blinked, covered their eyes, and will come out and follow us." "We'd better make tracks." "No," she said, "we must run, and make no tracks." God." "But...." "No buts. Right now we'd better get out of here." hampered by a woman, slinking through a frozen wilderness like an 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 "I thought only criminals were brought here." She nodded. "Criminals, and their children." "When will your people come again?" She shook her head. "Never. They are no longer my people. They have business is it of yours if she lives or dies? My race discarded such primitive logic long before it reached your level of development." "Yes," Stinson said, "and your race no longer exists." 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 for the first time. "Where is your ship?" "They will not find us...." in an audible range. Soon after, while they sat huddled together, watching the chaos of exuded impressions of death, of hopeful words solemnly spoken over lowered coffins, of cold earth and cold space, of dank, wet catacombs, of creeping, crawling nether things.
