Behind the Walls of Terra

  He pushed the bell ahead of him and then threw himself to one side so he would not be in front of the hoop. He had had enough experience with the Lords to suspect that the place on the other side was trapped. It was always best to throw something into the trap to spring it.

  There was a blast that deafened him. His face and the side of his body were seared with heat. He had shut his eyes, but light flooded them. And then he sat up and opened them in time to see the bell shooting across the pool, though still at its original height. It sped above the mercury pool and the walk and stopped only when it slammed into the wall. There it remained, a few inches from the wall because of its rebound.

  Immediately thereafter, the door fell outward and down against the walk. He could not hear it; he could hear only the ringing in his ears from the blast. But he saw the Beller dive through, the beamer held close to him, hit the floor, roll, and come up with the beamer held ready. By then, Kickaha had jumped up. As he saw the Beller look around and suddenly observe him, he leaped through the hoop. He had no choice. He did not think it would be triggered again, since that was not the way the Lords arranged their traps. But if the trap on the other side was reset, it would blow him apart, and his worries would be over.

  He was through, and he was falling. There were several thousands of feet of air beneath him, a blue sky above, and a thin horizontal bar just before him. He grabbed it, both hands clamping around smooth cold iron, and he was swinging at arm's length below a bar, the ends of which were set in two metal poles that extended about twenty feet out from a cliff.

  It was a triumph of imagination and sadism for Red Orc. If the prisoner was careless enough to go through the hoop without sending in a decoy, he would be blown apart before he could fall to death. And if he did not jump, but stepped through the gate, he would miss the bar.

  And, having caught the bar, then what?

  A man with lesser nerve or muscle might have fallen. Kickaha did not waste any time. He reached out with one hand and gripped the support bar. And as quickly let loose while he cursed and swung briefly with one hand.

  The support pole was almost too hot to touch.

  He inched along the bar to the other support pole and touched it. That was just as hot. The metal was not quite too hot to handle. It pained him so much that Kickaha thought about letting go. But he stuck to it, and finally, hurting so much that tears came to his eyes and he groaned, he pulled himself up over the lip of the cliff. For a minute he lay on the rock ledge and moaned. The palms of his hands and the inner sides of his fingers felt as if they had third-degree burns. They looked, however, as if they had only been briefly near a fire, not in it, and the pain quickly went away.

  His investigation of his situation was short because there was not much to see. He was on the bare top of a pillar of hard black rock. The top was wider than the bottom, and the sides were smooth as the barrel of a cannon. All around the pillar, as far as he could see, was a desolate rock plain and a river. The river split the circle described by the horizon and then itself split when it came to the column. On the other side, it merged into itself and continued on toward the horizon. The sky was blue, and the yellow sun was at its zenith. Set around the pillar near its base, at each of the cardinal points of the compass, was a gigantic hoop. One of these meant his escape to a place where he might survive if he chose the right one. The others probably meant certain death if he went through them.

  They were not an immediate concern. He had to get down off the pillar first, and at the moment he did not know how he was going to do that.

  He returned to the bar projecting from the cliff. The Beller could be about ready to come through the gate. Even if he was reluctant, he would have to come through. This was the only way out.

  Minutes passed and became an hour, if he could trust his sense of time. The sun curved down from the zenith. He walked back and forth to loosen his muscles and speed the blood in his legs and buttocks. Suddenly a foot and a leg came out of the blue air. The Beller, on the other side of the gate, was testing out the unknown.

  The foot reached here and there for substance and found only air. It withdrew, and, a few seconds later, the face of the Beller, like a Cheshire Cat in reverse, appeared out of the air.

  Kickaha's knife was a streak of silver shooting toward the face. The face jerked back into the nothingness, and the knife was swallowed by the sky at a point about a foot below where the face had been.

  The gate was not one-way. The entrance of the knife showed that. The fact that the Beller could stick part of his body through it and then withdraw it did not have anything to do with the one-way nature of some gates. Even a one-way gate permitted a body to go halfway through and then return. Unless, of course, the Lord who had designed it wished to sever the body of the user.

  Several seconds passed. Kickaha cursed. He might never find out if he had thrown true or not.

  Abruptly, a head shot out of the blue and was followed by a neck and shoulders and a chest and a solar plexus from which the handle of the knife stuck out.

  The rest of the body came in view as the Beller toppled through. He fell through and out and his body became smaller and smaller and then was lost in distance. But Kickaha was able to see the white splash it made as it struck the river.

  He took a deep breath and sat down, trembling. The Beller was at last dead, and all the Universes were safe forever from his kind.

  And here I am, Kickaha thought. Probably the only living thing in this universe. As alone as a man can be. And if I don't think of something impossible to do before my nonexistent breakfast, I will soon be one of the only two dead things in this universe.

  He breathed deeply again and then did what he had to do. It hurt just as much going back out on the pole as it had coming in. When he reached the bar, he rested on it with one arm and one leg over it. After the pain had gone away in his hands and legs, he swung up onto the bar and balanced himself standing on it. His thousands of hours of practicing on tightwires and climbing to great heights paid off. He was able to maintain his equilibrium on the bar while he estimated again the point through which the Beller had fallen. It was only an undefined piece of blue, and he had one chance to hit his target.

  He leaped outward and up, and his head came through the hoop and the upper part of his body and then he went "Whoof!" as his belly struck on the edge of the hoop. He reached out and gripped the stone with his fingertips and pulled himself on through. For a while, he lay on the stone until his heart resumed its normal beat. He saw that the bell was above him and the beamer was on the floor of the island only a foot from him.

  He rose and examined the bell. It was indestructible, and the tips of the antennas were encased in the same indestructible stuff. When the antennas were withdrawn, the tips plugged up the two tiny holes at the base of the bell. But the antennas themselves were made of less durable metal, and they had suffered damage from the blast. Or so he supposed. He could see no damage. In fact, he could not even see the antennas, they were so thin, though he could feel them. But the fact that the Beller had not sent the bell ahead through the gate proved to Kickaha that something had damaged the bell. Perhaps the blast had only momentarily impaired the relatively delicate brainwave and flight-governing apparatus inside the bell. This was, after all, something new, something which the Beller had not had time to field-test.

  Whatever had happened, it was fixed at its altitude above the island. And it still put up a weak resistance against a horizontal push. Kickaha presumed that its antennas must still be operative to some degree. Otherwise, the bell would net know how to maintain a constant height from the ground.

  It gave him his only chance to get to the ground several thousand feet below. He did not know how much of a chance. It might just stay at this level even if the ground beneath it were to suddenly drop away. If that happened, he still might be able to get to the top of the stone pillar.

  He put the strap of the beamer over one shoulder, hugged the bell to his chest, and st
epped out through the hoop.

  His descent was as swift as if he were dangling at the end of a parachute, a speed better than he had hoped for. From time to time, he had to kick against the sides of the pillar because the bell kept drifting back toward it, as if the mass of the pillar had some attraction for it.

  Then he was ten feet above the river and released his hold on the bell. He fell a little faster, hit the water, which was warm, and came up in a strong current. He had to fight to get to shore but managed it. After he had regained some of his strength, he walked along the shore until he saw the bell. It was stopped against the side of the pillar, like a baby beast nuzzling its gigantic mother. There was no way for him to get to it nor did he see any reason why he should.

  A few yards on, he found the body of the Beller. It had come to rest against a reef of rock which barely protruded above the surface of the small bay. Its back was split open, and the back of the head was soft, as if it had struck concrete instead of water. The knife was still in its solar plexus. Kickaha pulled it out, and cleaned it on the wet hat of the Beller. The fall had not damaged the knife.

  He pulled the body from the river. Then he considered the giant gates set hoop-like in the rock like the smaller one in the island in that other world. Two were on this side of the river and two on the other. Each was at the corner of a square two miles long. He walked to the nearest one and threw a stone into it. The stone went through and landed on the rock on the other side. It was one of Red Orc's jokes. Perhaps all four were just hoops and he would be stuck on this barren world until he starved to death.

  The next hoop, in the northeast corner also proved to be just that, a hoop.

  Kickaha was beginning to get tired and hungry. He now had to swim over the river, through a very strong current, to get to the other two hoops. The walk from one to the other was two miles, and if he had to test all four, he would walk eight miles. Ordinarily, he would not have minded that at all, but he had been through much in the last few hours.

  He sat down for a minute and then he jumped up, exclaiming and cursing himself for a fool. He had forgotten that gates might work when entered in one direction but not work in the other. Picking up a stone, he went around to the other side of the big hoop and cast the stone through it. The hoop was still just a hoop.

  There was nothing to do then but to walk back to the first hoop and to test that from the other side. It, too, gave evidence that it was no gate.

  He swam the river and got to the other side after having been carried downstream for a half-mile, thus adding to his journey. The beamer made the swimming and the walking more difficult, since it weighed about thirty pounds. But he did not want to leave it behind.

  The southwest hoop was only a huge round of metal. He went toward the last one while the sun continued westward and downward. It shone in a silent sky over a silent earth. Even the wind had died down, and the only sound was the rushing of the river, which died as he walked away from it, and his own feet on the rocks and his breathing.

  When he got to the northwest hoop, he felt like putting off his rock-throwing for a while. If this proved to be another jest of Red Orc, it might also prove to be the last jest that Kickaha would ever know. So he might as well get this over with.

  The first stone went through and struck the rock beyond.

  The second went through the other side and fell on the ground beyond.

  He jumped up and down and yelled his frustration and hit the palm of one hand with the fist of the other. He kicked at a small boulder and then went howling and hopping away with pain. He pulled his hair and slapped the side of his head and then turned his face toward the blind blue sky and the deaf bright yellow sun and howled like a wolf whose tail was caught in a bear trap.

  After a while he became silent and still. He might as well have been made of the light-red rock which was so abundant on this earth, except that his eyelids jumped and his chest rose and fell.

  When he broke loose from the mold of contemplation, he walked briskly but unemotionally to the river. Here he drank his fill and then he looked for a sheltered place to spend the night. After fifteen minutes, he found a hollow in the side of a small hill of hard rock that would protect him from the wind. He fell asleep after many unavoidable thoughts of the future.

  In the morning, he looked at the Beller's body and wondered if he was going to have to eat it.

  To give himself something to do, and also because he never entirely gave up hope or quit trying, he waded around in the shallows of the river and ran his hands through the waters. No fish were touched or scared into revealing their presence. It did not seem likely that there would be any, especially when there was an absolute absence of plant life.

  He walked to the top of the hill in the base of which he had slept. He sat on the hard round peak for a while, moving only to ease the discomfort of the stone on his buttocks. His situation was desperate and simple. Either Red Orc had prepared a way for his prisoner to escape if he was clever and agile enough or he had not. If he had not, then the prisoner would die here. If he had, then the prisoner-in this case, Kickaha -was just not bright enough. In which case, the prisoner was going to die soon.

  He sat for a long while and then he groaned. What was the matter with his brain? Sure, the stone had gone through the gates, but no flesh had passed through them. He should have tried them himself instead of trickily testing them only with the stones. The gates could be set up to trigger only if matter above a certain mass passed through them or sometimes only if protein passed through them. Or even only if human brainwaves came close enough to set them off. But he had been so concerned with traps on the other side that he had forgotten about this possibility.

  However, any activated gate might be adjusted to destroy the first large mass that entered, just as the gate from the room with the mercury pool had been booby-trapped.

  He groaned at the thought of the strain and sweat involved, but he had not survived thus far by being lazy. He lifted the body of the Beller onto his shoulder, thanking his fortunes that the man was small, and set off toward the nearest gate.

  It was a long, hot, and muscle-trembling day. The lack of food weakened him, and every failure at each gate took more out of him. The swim across the river with the dead weight of the corpse and the beamer drained him of even more. But he cast the body six times through the three gates, once through each side.

  And now he was resting beside the fourth. The Beller lay near him, its arms spread out, its face upturned to the hot sun, its eyes open, its mouth open, and a faint odor of corruption rising like invisible flies from it. At least, there were no real flies in this world.

  Time passed. He did not feel much stronger. He had to get up and throw the body through both sides. Just rolling it through was out of the question because he did not want to stand in the path of any explosion. It was necessary to stand by the edge of the hoop, lift the body up and throw it through and then leap to one side.

  For the seventh time, he did so. The body went through the hoop and sprawled on the ground. He had one last chance, and this time, instead of resting, he picked up the corpse and lifted it up before him until it was chest-high and heaved.

  When he raised his head up from his position on the rock, he saw that the body was still visible.

  So much for that theory. And so much for him. He was done for. He sat up instead of just lying there with his eyes closed. This move, made for no motive of which he was aware, saved his life.

  Even so, he almost lost it. The tigerish beast that was charging silently over the hard rock roared when it saw him sit up and increased the lengths of its bounds and its speed. Kickaha was so surprised that he froze for a second and thus gave the annual an edge. But he did not give enough. The beamer fired just as the animal rose for its final arc, and the ray bored through its head, sliced it, cut through the neck and chest, took off part of a leg, and drilled into the rock beyond. The body struck the ground and slid into him and knocked him off his feet an
d rolled him over and over. He hurt in his legs and his back and chest and hands and nose when he arose. Much skin had been burned off by his scraping against the rock, and where the body of the beast had slammed into his legs was a dull pain that was to get sharper.

  Nevertheless, the animal looked edible. And he thought he knew where it had come from. After he had cut off several steaks and cooked and eaten them, he would return to the northwest gate and investigate again.

  The beast was about a quarter larger than a Siberian tiger, had a cat-like build, thick long fur with a tawny undercoat and pale red zigzag stripes on head and body and black stocking-like fur on the lower part of the legs and the paws. Its eyes were lemonade-yellow, and its teeth were more those of a shark than those of a cat.

  The steaks tasted rank, but they filled him with strength. He took the Beller by the arm and dragged him the two miles to the gate. The corpse, by this time, was in a badly damaged condition. It stank even stronger when he lifted it up and threw it through the gate.

  This time, it disappeared, and it was followed by a spurt of oil from the gate that would have covered him if he had been standing directly before it within a range of ten yards. Immediately after, the oily substance caught fire and burned for fifteen minutes.

  Kickaha waited until long after the fire was out and then he jumped through with his beamer ready. He did not know what to expect. There might be another of the tigers waiting for him. It was evident that the first time he had thrown the Beller through it, he had set off a delaying activation which had released the beast through it some time after he had given up on it. It was a very clever and sadistic device and just the sort of thing he could expect from Red Orc. It seemed to him, however, that Red Orc might have given up setting any more machines. He would believe that it was very unlikely that anybody could have gotten this far. For a second, he was in a small bare room with a large cage, its door open, and a black dome on three short legs. Then, he was in another room. This one was larger and was made of some hard gray metal or plastic and lacked any decoration and had no furniture except a seatless commode, a washbowl and a single faucet, and a small metal table fastened to the floor with chains.
