The World of Ptavvs

by Larry Niven

  The statue had seemed formidable, armed and crouched and ready to spring. Now it was merely pitiful. Larry asked, “Can’t you bring him out of it?”

  Jansky shook his head violently. “No. You see that unshiny bump on his back?”

  Larry saw it, just below the apex of the triangular hump. It was just duller than the perfect mirror surface which surrounded it, and faintly reddened.

  “It sticks out of the field, just a little. Just a few molecules. I think it was the switch to turn, off the field. It may have burned off when our friend came through the air, or it may have rusted away while he was at the bottom of the ocean. So now there is no way to turn it off. Poor designing,” he added contemptuously.

  “Well, I think they are ready.”

  Larry’s uneasiness returned. They were ready. Machinery hummed and glowed outside the cage. The disk were steady on the humped contact machine, from which two multicolored cables led to the helmets. Four workmen in lab smocks stood nearby, not working but not idling. Waiting.

  Larry walked rapidly back to the table, poured and drained half a cup of coffee, and went back into the cage. “I’m ready too,” he announced.

  Jansky smiled. “Okay,” he said, and stepped out of the cage. Two workmen immediately closed the flap with a zipper twenty feet long.

  “Give me two minutes to relax,” Larry called.

  “Okay,” said Jansky.

  Larry stretched out on the couch, his head and shoulders inside the metal shell which was his contact helmet, and closed his eyes. Was Jansky wondering why he wanted extra time? Let him wonder. The contact worked better when he was resting.

  Two minutes and one second from now, what wonders would he remember?

  Judy Greenberg finished programming the apartment and left. Larry wouldn’t be back until late tonight, if then; various people would be quizzing him. They would want to know how he took the “contact.” There were things she could do in the meantime.

  The traffic was amazing. In Los Angeles, as in any other big city, each taxi was assigned to a certain altitude. They took off straight up and landed straight down, and the coordinator took care of things when two taxis had the same destination. But here, taxi levels must have been no more than ten feet apart. In the three years they had been living here Judy had never gotten used to seeing a cab pass that close overhead. The traffic was faster in Kansas but at least it was set to keep its distance.

  The taxi let her off at the edge of the top strip, the transparent pedestrian walk thirty stories above the vehicular traffic, in a shopping district. She began to walk.

  She noticed the city’s widely advertised cleanup project at work on many of the black-sided buildings. The stone came away startlingly white where the decades, sometimes centuries, of dirt had washed off. Judy noticed with amusement that only corner buildings were being cleaned.

  “I should have said, ‘What do you mean, experience in reading alien minds? Dolphins have been legally human since before you were born!’ That’s what I should have said,” said Judy to herself. She began to laugh quietly. That would have impressed him! Sure it would!

  She was about to enter a women’s leather goods store when it happened. In the back of her mind something slowed, then disappeared. Involuntarily Judy stopped walking. The traffic around her seemed to move with bewildering speed. Pedestrians shot by on twinkling feet or were hurled at suicidal velocities by the slidewalks.

  She had known something was coming, but she had never imagined it would feel like this, as if something had been jerked out of her.

  Judy went into the shop and began searching for gifts. She was determined not to let this throw her. In six hours he would be back.

  “Zwei minuten,” Doctor Jansky muttered, and threw the switch.

  There was a complaining whine from the machinery, rising in pitch and amplitude, higher and louder until even Jansky blinked uncomfortably. Then it cut off, sharply and suddenly. The cage was an unbroken mirror.

  The timing mechanism was inside the cage. It would cut the current in “one second.”

  “It is thirteen twenty,” said Jansky. “I suggest we should be back here at nineteen hours.” He left the room without looking back.

  Kzanol dropped the wire and pushed the button in his chest. The field must have taken a moment to build up, for the universe was suddenly jagged with flying streaks of light.

  Gravity snatched at him. If there were other changes in his personal universe Kzanol didn’t notice. All he knew was the floor beneath him, and the block of something beneath each heel-spur, and the weight which yanked him down. There was no time to tense his legs or catch his balance. He bleated and threw both arms out to break his fall.

  Jansky was the last to arrive. He came promptly at nineteen hours, pushing a keg of beer on a cart. Someone took it from him and wheeled it over to a table. His image wavered as it passed the cube; the wire wall couldn’t have been quite flat.

  A newcomer was in the building, a dumpy man about forty years old, with a blond Mohican haircut. When Jansky was rid of the keg he came forward to introduce himself. “I’m Dr. Dale Snyder, Mr. Greenberg’s experimental psychologist. I’ll want to talk to him when he gets out of there, make sure he’s all right.”

  Jansky shook hands and offered Snyder a fair share of the beer. At Snyder’s insistence he spent some time explaining what he hoped to accomplish.

  At nineteen twenty the cage remained solid. “There may be a little delay,” said Jansky. “The field takes a few minutes to die. Sometimes longer.”

  At nineteen thirty he said, “I hope the alien time field hasn’t reinforced mine.” He said it softly, in German.

  At nineteen fifty the beer was almost gone. Dale Snyder was making threatening noises, and one of the technicians was soothing him. Jansky, not a diplomat, sat staring fixedly at the silvered cube. At long intervals he would remember the beer in his paper cup and pour it whole down his throat. His look was not reassuring.

  At twenty hours the cube flickered and was transparent. There was a cheer as Jansky and Snyder hurried forward. As he got closer Jansky saw that the statue had fallen on its face, and was no longer under the contact helmet.

  Snyder frowned. Jansky had done a good job of describing the experiment. Now the psychologist suddenly wondered: Was that sphere really where the alien kept its brain? If it wasn’t, the experiment would be a failure. Even dolphins were deceptive that way. The brains were not in the bulging “forehead,” but behind the blowhole; the “forehead” was a weapon, a heavily padded ram.

  Larry Greenberg was sitting up. Even from here he looked bad. His eyes were glassy, unfocused; he made no move to stand up. He looks mad, thought Dorcas Jansky, hoping that Snyder wouldn’t think so too. But Snyder was obviously worried.

  Larry climbed to his feet with a peculiar rolling motion. He seemed to stumble, recovered, tottered to the edge of the wire curtain. He looked like he was walking on raw eggs, trying not to break them. He stooped like a weight lifter, bending his knees and not his back, and picked up something from where it lay beside the fallen statue. As Jansky reached the wire, Larry turned to him with the thing in his hands.

  Jansky screamed. He was blind! And the skin of his face was coming apart! He threw his arms over his face, feeling the same torment in his arms, and turned to run. Agony lashed his back. He ran until he hit the wall.

  A moment earlier she’d been sound asleep. Now she was wide awake, sitting straight up in bed, eyes searching the dark for—she didn’t know what. She groped for the light switch, but it wasn’t in the right place; her swinging arm couldn’t even find the bed control panel. Then she knew that she was on Larry’s side of the bed. She found his panel on her right and turned on the lamp.

  Where was he? She’d gone to sleep about seventeen, completely beat. He must be still at UCLA. Something had gone wrong, she could feel it!

  Was it just a nightmare?

  If it had been a nightmare she couldn’t remember a single det
ail. But the mood clung, haunting her. She tried to go back to sleep and found she couldn’t. The room seemed strange and awful. The shadows were full of unseen crawling monsters.

  Kzanol bleated and threw both arms out to break his fall.

  And went insane. The impressions poured riotously through his flinching senses and overwhelmed him. With the desperation of a drowning man trying to breathe water, he tried to sort them out before they killed him.

  First and most monstrous were the memories of an unfamiliar breed of slave calling itself Larry Greenberg. They were more powerful than anything that had ever reached his Power sense. If Kzanol had not spent so many years controlling alien life forms, growing used to the feel of alien thoughts, his whole personality would have been drowned.

  With a tremendous effort he managed to exclude most of the Greenberg mind from his consciousness. The vertigo didn’t pass. Now his body felt weird, hot and malformed. He tried to open his eye, but the muscles wouldn’t work. Then he must have hit the right combination and his eye opened. Twice! He moaned and shut it tight, then tried again. His eye opened twice, two distinct and separate motions, but he kept them open because he was looking down at his own body. His body was Larry Greenberg.

  He’d had enough warning. The shock didn’t kill him.

  Gingerly Kzanol began to probe the Greenberg mind. He had to be careful to get only a little information at a time, or he would be swamped. It was very different from ordinary use of the Power; it was a little like practicing with an amplifier helmet. He got enough to convince him that he really had been teleported, or telepathed, or some ptavv-sired thing, into an alien slave body.

  He sat up slowly and carefully, using the Greenberg reflexes as much as he dared because he wasn’t used to the strange muscles. The double vision tended to confuse him, but he could see that he was in a sort of metal mesh enclosure. Outside…Kzanol got the worst shock of all, and again he went insane.

  Outside the enclosure were slaves, of the same strange breed as his present self. Two of them were actually coming toward him. He hadn’t sensed them at all—and he still couldn’t.

  Powerless!

  A thrint is not born with the Power. Generally it takes around two thrintun years for the Power sense to develop, and another year before the young thrint can force a coherent order on a slave. In some cases the Power never comes. If a thrint reaches adulthood without the Power, he is called a ptavv. He is tattooed permanently pink and sold as a slave, unless he is secretly killed by his family. Very secretly. There is no better ground for blackmail than the knowledge that a wealthy family once produced a ptavv.

  An adult thrint who loses the Power is less predictable. If he doesn’t go thrint-catatonic he may commit suicide; or he may go on a killing spree, slaughtering either every slave or every thrint that crosses his path; or he may compulsively forget even the existence of a Power. The Powerloss is more crippling than going blind or deaf, more humiliating than castration. If a man could lose his intelligence, yet retain the memory of what he had lost, he might feel as Kzanol felt; for the Power is what separates Thrint from Animal.

  Still daring to hope, Kzanol looked directly at the advancing aliens and ordered them to STOP! The sense wasn’t working, but maybe…The slaves kept coming.

  They were looking at him! Helplessly he cast about for some way to stop them from looking. They were witnessing his shame, these undersized furry whitefoods who now considered him an equal. And he saw the disintegrator, lying near the abandoned Kzanol body’s out-flung hand.

  He got to his feet all right, but when he tried to hop he almost fell on his face. He managed to walk over, looking like a terrified novice trying to move in low gravity. The nearest slave had reached the cage. Kzanol bent his funny knees until he could pick up the disintegrator, using both hands because his new fingers looked so fragile and delicate and helpless. With a growl that somehow got stuck in his throat, he turned the digging instrument on the aliens. When they were all cowering on the floor or against the walls he whirled and ran, smashed into the wire, backed off and disintegrated a hole for himself and ran for the door. He had to let Greenberg through to open the door for him.

  For a long time he thought only of running.

  There were green lights below, spaced sparsely over the land between the cities. You had to fly high to see two at a time. Between cities most cars did fly that high, especially if the driver was the cautious type. The lights were service stations. Usually a car didn’t need servicing more than twice a year, but it was nice to be able to see help when you were in open country. The loneliness could get fierce for a city man, and most men were city men.

  It was also nice to know you could land near a green light without finding yourself on top of a tree or halfway over a cliff.

  Kzanol steered very wide of the cities, and avoided the green lights too. He couldn’t have faced a slave in his present state. When he left the physics level he had gone straight to the roof parking levels, to the haven of his Volkswagen, and taken it straight up. Then he had faced the problem of destination. He didn’t really want to go anywhere. When he reached altitude he set the car for New York, knowing that he could change back to California before he got there. Henceforth he let the car drive itself, except when he had to steer around a city.

  He did a lot of steering. The green country was more nearly islands in a sea of city than vice versa. Time and again he found narrow isthmuses of city, lines of buildings half a mile across following old superhighways. He crossed these at top speed and went on.

  At one hour he had to bring the car down. The drive had been grueling. Only his mad urge to flee had kept him going; and he was beginning to know that he had nowhere to flee to. He felt aches and pains that were sheer torture to him, although Greenberg would have ignored them from habit. His fingers were cramped and sore; they seemed more delicate than ever. He was not mistaken in this. The Greenberg memory told him why the little finger of his left hand ached constantly: a baseball accident that had healed wrong. And Greenberg had taken this crippling disaster for granted! Kzanol was almost afraid to use his hands for anything. There were other pains. His cramped muscles ached from sitting in one position for five hours. His right leg was in agony from its constant pressure on the throttle during override maneuvers. He itched everywhere that clothing pressed against his body.

  He brought the car down in the middle of a stunted wood in Arizona. Hurriedly lie got out and stripped off his clothes. Much better! He tossed them into the right-hand seat—he might need them again sometime—got back in and turned on the heater. Now he itched where he touched the seat, but he could stand it.

  He had been letting Greenberg’s reflexes drive the car, and in the process had gotten used to the presence of Greenberg in his mind. He could draw on the memory set with little discomfort and without fear. But he had not become used to the alien body he now wore, and he had no slightest intention of adjusting to the loss of the Power. Kzanol wanted his body back.

  He knew where it was: he’d seen it when he got the disintegrator. The Greenberg memories filled in the details for him. Obviously he had thrown the disintegrator when he put his arms out to protect himself. The body would keep until he found some way of getting back to it.

  To do that he would need a way to operate the men who operated the contact machine. He would need a great deal of technological help to break the Kzanol body out of stasis; he’d seen, as Greenberg, the rusted spot on his back. But to get all this help he needed the Power. How? His human brain didn’t have the Power in it.

  But there was one chance. Humans had space travel, remembered Kzanol/Greenberg. Pitiful space travel: ships that took decades to cross between the inhabited worlds, and days even to cruise the planets of the “solar system.” But space travel it was. If he could find the F124 system, and if it were close enough to reach, he could get the amplifier helmet. And Greenberg had had rudimentary telepathy.

  The helmet could boost his tiny talent into a semb
lance of thrintun Power.

  Where was he now? He must have missed F124, Kzanol decided, and gone on to a haphazard collision with this planet Earth. Where and when had he landed? Could he reach the lost planet within Greenburg’s lifetime?

  Greenberg’s body wanted dinner (it was 1:20 hours), water, and a cigarette. Kzanol had no trouble ignoring the hunger and thirst, for a thrint would kill himself if he ate enough to satisfy his hunger, and rupture his storage sac if he drank until he wasn’t thirsty. The battle for food had been very fierce among the thrint’s dumb ancestors. But he had cigarettes. He smoked and found that he liked it, although he had to fight an urge to chew the filter.

  Where was he? He let Larry Greenberg’s memory come to the surface. High school. History class, with lousy grades. The race for space; Moon bases; Mars bases. The Belt. Colonization of the Belt. The economics behind the Belt. Confinement Asteroid. Overpopulation on Earth. Fertility Laws; Fertility Board; Superman Insurrection. Sanction against the Belt, during an argument over the use of the Jovian moons. There was a lot of extraneous material coming through, but Kzanol was getting a good picture of the solar system. He was on the third planet, and it was binary. He had been extremely lucky to hit it.

  The UN power sender on Mercury. Failure of the economic sanction. Limits of Belt autonomicity. Industrial warfare. Why was the Belt being treated as a villain? Forget it. Belt mining of Saturn’s rings for water. Saturn’s rings. Rings!

  “Youch!” Kzanol hurled the cigarette butt away and stuffed his burnt fingers in his mouth.

  F124. So this is F124, he thought. It doesn’t look like F124. He started to shiver, so he turned up the heater.

  At one-thirty Judy got up and went out. The nightmare feeling had become too much to bear, alone in the dark. And Larry hadn’t called.

  A cab dropped to the corner in answer to her ring. She didn’t know the address of the UCLA Physics Level, but there was a phone in the cab. She had Information type the address on the cab destination board. The cab whirred and rose.
