<passage>:
She prayed that a God would come from the skies and carry her away to bright adventures. But when he came in a metal globe, she knew only disappointment—for his godliness was oddly strange! [Transcriber's Note: This etext was produced from Planet Stories March 1943. It was twilight on Venus—the rusty red that the eyes notice when their closed lids are raised to light. Against the glow, fantastically twisted trees spread claws of spiky leaves, and a group of clay huts thrust up sharp edges of shadow, like the abandoned toy blocks of a Venusian speech, "How I envy you, Koroby! I wish I were being married She left them, moving gracefully to the door. Venus-girls were generally of truly elfin proportions, so delicately slim that they seemed incapable of the slightest exertion. But Koroby's body deepen to purple. "I want romance," she said, so softly that the girls had to strain forward to hear her. "I wish that there were other worlds than this—and that someone would drop out of the skies and claim the Stone City." She ran slim hands down her sides, smoothing the blue sarong she trilled softly to herself, "Yes, I am beautiful tonight—the loveliest if only He would come ... the man of my dreams!" the lights of the other litter-bearers, colored sparks as befitted a wedding-conveyance. The winking lights were enclosed in shells of colored glass for another reason—the danger of their firing the papery jungle verdure. them they rustled dryly. Too bad—it had been such a dry year— of elephant-eared leaves. Above the monotonous music came the hiss of the torches, the occasional startled cry of a wakened bird. The glow of the flames, in the dusty air, hung around the party, sharply defined, "What was it?" another bearer asked. "Thought I heard something," the other replied. "Shrill and high—like something screaming—" There was a babble of voices as the musicians crowded together, asking what had it been, and where—just exactly—could one suppose it had happened, that thunder—was it going to storm! They waited, but nothing further happened—there were no more stabs of "I don't care," she said. "Take me there." Her order had reached the others' ears, and they slowed their pace. "Lady—believe me—it's impossible. There's nothing but matted jungle won't take me, I'll go by myself. I must get to that fire, whatever it is!" She put a hand to her heart. "I must! I must!" Then she faced the green glare again, smiling to herself. demoralized. The musicians had not accompanied them, preferring to carry the message to Yasak in the Stone City that his prospective bride had gone off on a mad journey. The bearers were powdered grey with dust, striped with blood where the dry grass-stems had cut them. her carefully-arranged braids had fallen loose dust on her face had hid its youthful color, aging her. globular before the crash, and was pierced with holes like windows. What could it possibly be? A house? But whoever heard of a metal house? Why, who could forge such a thing! Yasak's house in the City had iron doors, and they were considered one of the most wonderful things of the age. It would take a giant to make such a ponderous thing as this. A house, fallen from the sky? The green lights poured out of its crumpled part, and a strange bubbling and hissing filled the air. Koroby hastily grasped a corner of her gown, moistened it with saliva, and scrubbed her face. She rearranged her hair, and stepped forward. "Don't go there—it's magic—he'll cast a spell—!" one of the bearers whispered urgently, reaching after her, but Koroby pushed him away. The almost frightening, unhuman, mechanical. It was unlined and without expression, somehow unreal. Mysterious, compelling. He was clothed very peculiarly. A wonderfully-made metallic garment enclosed his whole body—legs and all, unlike the Venus-men's tunics. Even his feet were covered. Perhaps it was armor—though the Venus-men the man's head except his face. Around his waist was a belt with many incomprehensible objects dangling from it. If he was so well armored, why was he not carrying a sword—a dagger at least! Of what use were those things on his belt—for instance, that notched L-shaped thing? It would not even make a decent club! Venus!" he said slowly. "No name? But who are you? Where are you from? And what is that?" She pointed at the metal globe. "The vehicle by which I came here from a land beyond the sky," he said. "From a world known as Terra." Terra—it is incredibly far away." The glare was beginning to die, the green flames' hissing fading to a "I read your mind," he explained indifferently. "I have a remarkable memory." "Remarkable indeed!" she mocked. "No one here could do that." "But my race is infinitely superior to yours," he said blandly. "You little people—ah—" He gestured airily. Her lips tightened and her eyes narrowed. "And I?" superior to me— me ?" He looked her up and down. "Of course!" Her eyes jerked wide open and she took a deep breath. "And just who do you think you are? A god?" He shook his head. "No. Just better informed, for one thing. And—" was not quite a sigh. "Here I am stranded on Venus, my ship utterly "Good," he said. "Let's go there." They took another glance at the metal globe and the green fire, which she was bleeding from many scratches. She tripped over tangled roots and exclaimed in pain. Then the man took one of the strange implements from his belt, pressed a knob on it, and light appeared as if by magic! a strange light that gave no heat, nor flickered in the breeze. Finally she accepted it from him, but carried it gingerly at arm's length. "Call me Robert. It is an ancient name on Terra." because she wanted to impress this indifferent man that she was not as had happened. "A green light—loud sounds—fire—this man there—" and then dropped into sleep. weave. The furniture was elegantly carved and painted there were even been lying here for weeks. Where's Yasak? Where's the strange man in armor?" striding toward his sky-ship, a widening cloud of dust rising behind to hear. She watched him a little longer. Then she deliberately stooped and drew the firestone out of its sheath. She touched it to a blade of the tall writhing fire, her hand protectively over her face. The flames crackled at first—like the crumpling of thin paper. Then, as they widened and began climbing hand over hand up an invisible its roar came shouts from the City. The flames rose in a monstrous twisting pillar, brighter than even the dust-palled sky, lighting the buildings and the prairie. The heat was dreadful. laid clear. There were exclamations of amazement and perplexity from the people. It was a metal skeleton, and the fragments of complicated machinery, caked with soot. "He wasn't human at all!" Yasak marvelled. "He was some kind of a toy made to look like a man—that's why he wore armor, and his face never changed expression—" "Magic!" someone cried, and backed away. "Magic!" the others repeated, and edged back ... and that was the end of one of those robots which had been fashioned as servants for Terrestial men, made in Man's likeness to appease Man's vanity, then conquered him.
