WALTER M. MILLER, JR. I Made You IT HAD DISPOSED of the enemy, and it was weary. It sat on the crag by night. Gaunt, frigid, wounded, it sat under the black sky and listened to the land with its feet, while only its dishlike ear moved in slow patterns that searched the surface of the land and the sky. The land was silent, airless. Nothing moved, except the feeble thing that scratched in the cave. It was good that nothing moved. It hated sound and motion. It was in its nature to hate them. About the thing in the cave, it could do nothing until dawn. The thing muttered in the rocks "Help me! Are you all dead? Can't you hear me? This is Sawyer. Sawyer calling anybody, Sawyer calling anybody?" The mutterings were irregular, without pattern. It filtered them out, refusing to listen. All was seeping cold. The sun was gone, and there had been near-blackness for two hundred and fifty hours, except for the dim light of the sky-orb which gave no food, and the stars by which it told the time. It sat wounded on the crag and expected the enemy. The enemy had come charging into the world out of the unworld during the late afternoon. The enemy had come brazenly, with neither defensive maneuvering nor offensive fire. It had destroyed them easily?first the big lumbering enemy that rumbled along on wheels, and then the small enemies that scurried away from the gutted hulk. It had picked them off one at a time, except for the one that crept into the cave and hid itself beyond a break in the tunnel. It waited for the thing to emerge. From its vantage point atop the crag, it could scan broken terrain for miles around, the craters and crags and fissures, the barren expanse of dust-flat that stretched to the west, and the squarish outlines of the holy place near the tower that was the center of the world. The cave lay at the foot of a cliff to the southeast, only a thousand yards from the crag. It could guard the entrance to the cave with its small spitters, and there was no escape for the lingering trace of enemy. It bore the mutterings of the hated thing even as it bore the pain of its wounds, patiently, waiting for a time of respite. For many sunrises there had been pain, and still the wounds were unrepaired. The wounds dulled some of its senses and crippled some of its activators. It could no longer follow the flickering beam of energy that would lead it safely into the unworld and across it to the place of creation. It could no longer blink out the pulses that reflected the difference between healer and foe. Now there was only foe. "Colonel Aubrey, this is Sawyer. Answer me! I'm trapped in a supply cache. I think the others are dead. It blasted us as soon as we came near. Aubrey from Sawyer, Aubrey from Sawyer. Listen! I've got only one cylinder of oxygen left, you hear? Colonel, answer me!" Vibrations in the rock, nothing more?only a minor irritant to disturb the blessed stasis of the world it guarded. The enemy was destroyed, except for the lingering trace in the cave. The lingering trace was neutralized however, and did not move. Because of its wounds, it nursed a brooding anger. It could not stop the damage signals that kept firing from its wounded members, but neither could it accomplish the actions that the agonizing signals urged it to accomplish. It sat and suffered and hated on the crag. It hated the night, for by night there was no food. Each day it devoured sun, strengthened itself for the long, long watch of darkness, but when dawn came, it was feeble again, and hunger was a fierce passion within. It was well, therefore, that there was peace in the night, that it might conserve itself and shield its bowels from the cold. If the cold penetrated the insulating layers, thermal receptors would begin firing warning signals, and agony would increase. There was much agony. And, except in time of battle, there was no pleasure except in devouring sun. To protect the holy place, to restore stasis to the world, to kill enemy?these were the pleasures of battle. It knew them. And it knew the nature of the world. It had learned every inch of land out to the pain perimeter, beyond which it could not move. And it had learned the surface features of the demiworld beyond, learned them by scanning with its long-range senses. The world, the demiworld, the unworld?these were Outside, constituting the universe. "Help me, help me, help me! This is Captain John Harbin Sawyer, Autocyber Corps, Instruction and Programming Section, currently of Salvage Expedition Lunar-Sixteen. Isn't anybody alive on the Moon? Listen! Listen to me! I'm sick. I've been here God knows how many days ... in a suit. It stinks. Did you ever live in a suit for days? I'm sick. Get me out of here!" The enemy's place was unworld. If the enemy approached closer than the outer range, it must kill; this was a basic truth that it had known since the day of creation. Only the healers might move with impunity over all the land, but now the healers never came. It could no longer call them nor recognize them?because of the wound. It knew the nature of itself. It learned of itself by introspecting damage, and by internal scanning. It alone was "being." All else was of the outside. It knew its functions, its skills, its limitations. It listened to the land with its feet. It scanned the surface with many eyes. It tested the skies with a flickering probe. In the ground, it felt the faint seisms and random noise. On the surface, it saw the faint glint of starlight, the heat-loss from the cold terrain, and the reflected pulses from the tower. In the sky, it saw only stars, and heard only the pulse-echo from the faint orb of Earth overhead. It suffered the gnawings of ancient pain, and waited for the dawn. After an hour, the thing began crawling in the cave. It listened to the faint scraping sounds that came through the rocks. It lowered a more sensitive pickup and tracked the sounds. The remnant of enemy was crawling softly toward the mouth of the cave. It turned a small spitter toward the black scar at the foot of the Earthlit cliff. It fired a bright burst of tracers toward the cave, and saw them ricochet about the entrance in bright but noiseless streaks over the airless land. "You dirty greasy deadly monstrosity, let me alone! You ugly juggernaut, I'm Sawyer. Don't you remember? I helped to train you ten years ago. You were a rookie under me . . . heh heh! Just a dumb autocyber rookie ... with the firepower of a regiment. Let me go. Let me go!" The enemy-trace crawled toward the entrance again. And again a noiseless burst of machine-gun fire spewed about the cave, driving the enemy fragment back. More vibrations in the rock "I'm your friend. The war's over. It's been over for months . . . Earthmonths. Don't you get it, Grumbler? 'Grumbler'?we used to call you that back in your rookie days?before we taught you how to kill. Grumbler. Mobile autocyber fire control. Don't you know your pappy, son?" The vibrations were an irritant. Suddenly angry, it wheeled around on the crag, gracefully maneuvering its massive bulk. Motors growling, it moved from the crag onto the hillside, turned again, and lumbered down the slope. It charged across the flatlands and braked to a halt fifty yards from the entrance to the cave. Dust geysers sprayed up about its caterpillars and fell like jets of water in the airless night. It listened again. All was silent in the cave. "Go 'way, sonny," quavered the vibrations after a time. "Let pappy starve in peace." It aimed the small spitter at the center of the black opening and hosed two hundred rounds of tracers into the cave. It waited. Nothing moved inside. It debated the use of radiation grenade, but its arsenal was fast depleting. It listened for a time, watching the cave, looming five times taller than the tiny flesh-thing that cowered inside. Then it turned and lumbered back across the flat to resume its watch from the crag. Distant motion, out beyond the limits of the demiworld, scratched feebly at the threshold of its awareness?but the motion was too remote to disturb. The thing was scratching in the cave again. "I'm punctured, do you hear? I'm punctured. A shard of broken rock. Just a small leak, but a slap-patch won't hold. My suit! Aubrey from Sawyer, Aubrey from Sawyer. Base Control from Moonwagon Sixteen, Message for you, over. He he. Gotta observe procedure. I got shot! I'm punctured. Help!" The thing made whining sounds for a time, then: "All right, it's only my leg. I'll pump the boot full of water and freeze it. So I lose a leg. Whatthehell, take your time." The vibrations subsided into whining sounds again. It settled again on the crag, its activators relaxing into a lethargy that was full of gnawing pain. Patiently it awaited the dawn. The movement toward the south was increasing. The movement nagged at the outer fringes of the demiworld, until at last the movement became an irritant. Silently, a drill slipped down from its belly. The drill gnawed deep into the rock, then retracted. It slipped a sensitive pickup into the drill hole and listened carefully to the ground. A faint purring in the rocks?mingled with the whining from the cave. It compared the purring with recorded memories. It remembered similar purrings. The sound came from a rolling object far to the south. It tried to send the pulses that asked "Are you friend or foe," but the sending organ was inoperative. The movement, therefore, was enemy?but still beyond range of its present weapons. Lurking anger, and expectation of battle. It stirred restlessly on the crag, but kept its surveillance of the cave. Suddenly there was disturbance on a new sensory channel, vibrations similar to those that came from the cave; but this time the vibrations came across the surf...
