Slow Train to Arcturus Page 10

  "Howard," said Kretz.

  He was learning to read the alien's expressions by now. That was irritation. "Yes?" he answered.

  "Do you see these bones? That is what will happen to you if you do not put on a suit, helmet and boots and clip on the air tank."

  It was a powerful argument, when put like that. Howard stripped. He allowed Kretz to help him dress, and they dealt with the unfamiliar fastenings together. Kretz also found a rack of cylinders. He took one and fitted it onto a box-device on the back of the suit. Howard was startled to see a plate on his wrist change color from red to green. He pointed it out.

  Kretz pursed his lips into his smile. "Good. It must be an air-pressure indicator. I did not know if the cylinders would still retain pressure. The humans who built this were first-class engineers."

  He didn't say that the Brethren weren't, but somehow Howard got the feeling that he was saying and you carry water in wooden buckets.

  Kretz handed Howard a helmet. "Once that is on we will not be able to talk. I am going to attach you to me. If you need to say something, press your helmet against mine." Howard noticed, in the dissociated way of someone who is on the verge of panic, that Kretz had extended a hood from the suit that he was so fond of and that a transparent screen now covered his face. He noticed that Kretz had taken the little parcel of journey bread and preserves and soup and put it into a suit too. And then put boots and hood onto that, which was truly strange. Did the alien think that it had a life of its own?

  "Depressurization sequence beginning," said the box voice, as Kretz clicked the helmet into place. Howard still wanted to know: how did they fit someone into a box that size? Anyway, he preferred thinking about that type of problem than about what he was about to see, outside of New Eden. Ideas on the subject kept troubling his mind as Kretz attached a rope onto a clip on his suit's belt. Would there be the corridors of Earth-the source of persecution and corruption-out there? Or would there be a way through to Kretz's "ship"?

  Kretz had tried to explain. All that Howard had managed to understand was that it was big and empty and that the light out there did not come from light-tubes. And it was not easy to cross.

  Then, after an eternity, a door at the far side of the room slid open, and Kretz pointed at it. Awkwardly, as his boots seemed to stick to the floor, Howard moved forward. Out onto a metal platform… and froze in the doorway.

  He was looking out onto more emptiness than his mind could deal with. Tiny points of light turned in the blackness. And there was no end to it. He knew that he was screaming, but he couldn't help himself.

  Eventually Kretz had to pull him inside. The door to the terrible nothingness closed. Howard just stood there. Even the bones looked familiar and safe compared to that.

  "It is now safe to release the helmet seals," a voice said-the same voice that had spoken from the box.

  Voices in your head! A sure sign of demonic possession! Brother Galsson had been right.

  Kretz lifted the helmet off Howard's head. "I could not prepare you," he said.

  Howard shook his head, slowly. "What was that?"

  "That was what you would call 'the heavens,' " explained Kretz.

  "Not heaven," said Howard, sitting down, slumping against the wall. "Not hell either. That is a place of hellfire. Out there it is just dark."

  "It is, out here, far from the light of the sun."

  "But it is so big. So open. Where is the end of it?" Howard was still stunned and fearful.

  "We're not sure if there is one," answered Kretz.

  Howard's next words surprised himself. But they were drawn from somewhere deep inside his mind. "We've been so small. How could we be so small in the face of something so great? We have hidden away from it."

  The alien cocked his head in that oddly human gesture. "It is both frightening and magnificent."

  "Yes. Both frightening and magnificent," said Howard. He'd never had the experience that others had described of a spiritual enlightenment. And now, in the midst of his fear and the smell that came from the suit… he knew that he had finally done so. "I have looked on the infinity of God," he said humbly. "And I was very afraid. What were the spots of light, Brother Kretz?"

  "Suns. Very far off suns."

  Was it not written "And the sun shall not smite thee by day.. ."? So that was what it referred to.

  "The brightest one you saw is ours. Miran is the second world orbiting it."

  Kretz had obviously learned to recognize Howard's blank look. "That is where I came from. My spacecraft crossed the heavens to come here."

  Howard stared in awe at the alien. "How could anyone cross that?"

  Kretz narrowed his lips in his smile. "Howard. As I said to you: This 'New Eden' of yours is a spacecraft. Or, rather, your whole world is part of a spacecraft. We saw you crossing the heavens and came to find out what you were."

  Howard wrestled with this one. "New Eden is also definitely this thing you call a spacecraft?" Yes. He remembered that Kretz had said that before. But that was before it meant anything to him.

  "Yes," Kretz nodded. "Much bigger than ours, intended for a far longer journey."

  Howard looked at the metal floor. "I believed… in my heart of hearts that New Eden was all that really existed."

  Kretz shook his head. "There are millions and millions of worlds out there. Orbiting around hundreds of millions of suns. They're many thousands of times bigger than New Eden," said the alien, cheerfully compounding Howard's turmoil. "I suppose in a way, you are naturally going to be frightened…"

  "You don't understand," said Howard, interrupting, fierce feeling overwhelming politeness. He had to tell someone, and Kretz was the only person there was to tell. "I have been kept in a tiny little cage all my life. With limits. Limits on what I could think. Limits on what I could do. It chafed me. But I did not know why. I didn't even know that I was inside the cage. I feel as if I've been a chick growing inside an egg. I didn't know there was an outside to the egg. Why didn't you tell me?!"

  Kretz smiled. "I was not sure that you could deal with a bigger universe. Your kind have lived in a very sheltered and protected environment for many generations, even if you did build this ship."

  "I don't think some of us would deal with it too well," admitted Howard. "Someone like Brother Galsson, probably couldn't. It still frightens me, but another part of me wants to go out and see it. See all of it."

  This definitely amused Kretz. "There is rather a lot of it. I will settle for seeing if we can get to my spacecraft. I must be honest with you, Howard. If we can go along the outer skin of the habitats I don't really need you, except perhaps as security. I wanted a human with me if I had to venture back inside. I am very afraid of your kind."

  Howard was a little puzzled by this. But he'd heard what Kretz had said about the next space habitat. He was part way to understanding just what a habitat was, now. It would be a world such as his own New Eden. A tiny enclosed piece of greenness and light in an infinity of blackness. But that Eden had been taken over by striped-faced snakes.

  He took a deep breath. "But if you cannot, you will need my help. So: let us go and find out."

  "Very well. Put on your helmet again. It is important that we move quite fast out there."

  Howard knew that it would be the most courageous thing he'd ever done. But somehow, he could not have resisted trying again. He took a deep breath. Held up a hand to stop Kretz. "Brother. I will try not to look other than at my feet as I may slow you down. Will you lead me?"

  This time Howard kept his eyes on the metal floor of the hanging catwalk, trying not to be distracted by the vast panoply visible through the bars.

  The headlights helped, making a narrow pool of light for his feet. He couldn't help but see some of space, and the vastness of New Eden above him, but at least it kept him from being too distracted.

  They walked a long way. And then, when he was just daring to take a peek sideways, they stopped. Kretz was at a gate. Beyond it, Howard cou
ld see a metal-runged ladder. However, despite Kretz's efforts, the gate did not open. It appeared to have no form of catch. After some passage of time, they walked back to the airlock.

  Howard had gotten far more used to looking around by then. He could see, across the blackness, the cable that linked New Eden to the next habitat. It was a good five cubits thick-still an incredibly frail link for something as vast as their world.

  Once the airlock had cycled closed, Howard removed his helmet. Kretz sat down, next to the bones of the exiled brethren, and-even if he was alien-looked despairing. "I've lost the tool I need to open the gate," he said. "I used it to gain access to the tube I crawled down to reach your habitat. I thought we could go around, outside and over the equatorial ridge."

  He sighed, again, an oddly human mannerism. "I cannot get back to my ship. The only possibility is the lander, and that is five habitats on from here."

  Howard patted his arm awkwardly. "Then that is what we must do."

  "I am afraid," said Kretz.

  "So am I," admitted Howard. "Although, for me, these experiences have almost become dreamlike, they are so far beyond my understanding, Kretz. I think I would be rigid with terror if I wasn't… somehow detached." He paused. "I have one question… all of those spots of light?"

  "Suns, yes. Very distant suns, as I told you."

  "Why are the suns moving? Where are they going to?" asked Howard.

  "The suns are not moving. Or at least they're not moving very fast. The space habitat-New Eden-spins, to provide a simulated gravity through centripetal force."

  Howard looked blankly at him. "I don't understand it," he said, eventually. "But I want to. I want to understand it all."

  Kretz drew his lips into his smile. "Like space, there is quite a lot of it. What I am going to suggest we do now is entirely insane. That was how I got my place on this expedition. Because I am a little mad."

  "Mad?" asked Howard, warily.

  "Yes. By the standards of my people. Of course there are many mad people, but not all of them are biologists and mechanical engineers." He paused. "We need to cross the gap between the two habitats. I crossed the gap by crawling down the hollow inside of the cable. It is plainly intended to be possible. There are other pipes in there, perhaps linking all the habitats, perhaps there to replenish ones that are in need. But we can't get in there. So we must go along the outside."

  "It looked like a long way to climb," said Howard, doubtfully.

  "It would be too far to climb. Besides I do not think we could. But I think we can fly," said Kretz.

  Howard looked long and hard at him. "You have assured me you were not an angel, or a demon. I have seen your body, and I know you have no wings. How do you plan to fly? Even in the low gravity heart of New Eden, men cannot fly. Can you?"

  "I'd forgotten that you would be familiar with low gravity. When we leave the ship and go along the cable, there will be virtually no gravity. And the slightest thrust would send us away into the heavens. There is nothing to push against to come back, either."

  Howard digested this. "Then I think we must use this rope that they have seen fit to equip these suits with. If we tied it to one wrist and then passed it around the cable, and then tied it to the other wrist again… but how strong is that arm of yours?"

  Kretz nodded. "I had thought about that. My arm will be strong enough. But I am surprised you thought of it, Howard. You have surprised me a great deal. You appear to be such primitive people, and yet you grasp things with speed."

  "I've surprised myself," said Howard, standing just a little taller. "But all of this has left me very hungry. I saw you put the food into a suit. Were you planning to take it with us, or should we eat?"

  Kretz shook his head and smiled. "Perhaps we Miranese need you humans. I had forgotten about it."

  "Why did you put it in the suit?" asked Howard.

  "Depressurization and cold would have ruined it," explained Kretz.

  "There is still so much for me to learn," said Howard humbly.

  He hadn't yet learned to work out quite what alien laughter sounded like, but he suspected that the gurgling noise Kretz made might just be that.

  They ate, carefully sitting where the bones were not visible. Then Kretz rigged a sling from a safety rope to carry several extra bottles of air. Or tried to, at least. Once Howard had worked out what the alien was doing, he took over. Howard had made things with his hands all his life. Kretz plainly had not. Besides, if they could take cylinders he could take his clothes, even use them to make part of the carrier.

  When it was time to go, Kretz turned to Howard. "We could be dead, shortly. Do you not wish to remain here?"

  A part of Howard wanted to stay, very, very badly. Even staying here with the bones was better than what even the alien plainly regarded as a mad enterprise. But…

  He'd lived through so many mad enterprises since he came through that airlock. The frequency of them had numbed him. He just stood up, and took the sling. They had no way of taking the rest of the provisions, sadly. It went against every grain of Howard's conservative soul to waste.

  They went out again. By now Howard felt that he was becoming a seasoned explorer of space. He was quite blase about it. Not even shaking that much.

  But he was totally unprepared for what Kretz did, this time.

  The alien climbed out between the bars of the catwalk where it met the airlock and was a little wider, and turned himself upside down so his boots came into contact with the white roof… well, not really the roof. The outside of New Eden itself. He hung upside down. Like a bee. And then he motioned for Howard to follow.

  Doing so was the greatest leap of faith that the New Eden man had ever made.

  His boots also stuck… and sank slightly into the white stuff. But to walk-having to pull loose each foot, hanging-was pure torture. Howard was sure that he was going to fly off into the endless void with each step

  The strangest thing was that it got slowly better. By the time the base of the cable came in sight, Howard didn't feel as if he was walking upside down any more. Instead, the force tried to drag him backwards. But it decreased, step by step, until, at last, they stood at the cable.

  There was a railing around the base of it, and it stretched up into the blackness, to the distant curve of another habitat, like a huge bead on a string. The cable was several feet thick, but it seemed very thin when it had the gulf of the void all around it. Without conscious thought, Howard began to pray, the simple prayers of his childhood.

  They walked around the cable-it was more like a very thick pole in appearance-and put the ropes around it, then attached them to their belt snap-links. Then came the worst. Kretz reclaimed the sling-bag, and got up onto the rails, using the rope around the cable to keep his balance. Breathing hard, although Kretz had said he shouldn't, Howard got up too. He put a hand against the great cable to steady himself.

  As he fell, he realized that the cable was turning-or perhaps New Eden was. But he was floating only secured by the thin cord on his belt. And his fall had pulled his partner too… Or perhaps Kretz had jumped.

  They were free-floating a few yards above the turning railings. And then Kretz took out an air cylinder, opened the valve at the top, and pointed it back at the outside of New Eden. They began to move, not too fast, but steadily, toward the next space habitat.

  Flight was something the bees could keep to themselves, so far as Howard was concerned.

  Theirs was not a fast progression. As they crossed farther out into the gulf, Howard had a long time to consider how insignificant he was against the hugeness of God's creation. He even got detached enough to think that the experience would do the likes of Brother Galsson the world of good.

  They were using the third and last cylinder when Howard noticed something faintly alarming. The disc on his arm that Kretz had said indicated air-pressure was no longer green. Instead a good two thirds of it was now red. And although Kretz was shaking the cylinder in his hand furiously…
they weren't moving forward very fast.

  The turning surface of the new habitat was still a good hundred yards below them. And if he was any judge of alien expression-Kretz was at edge of panic. Kretz threw the cylinder back toward New Eden. It produced a few yards of movement… They were still a long way from the next Habitat.

  And plainly the alien was out of ideas as well as the air that had pushed them this far.

  Howard took a deep breath-even if he shouldn't do so. And pulled himself closer to the cable. He was one of the Society of Brethren. He knew God had given man muscles to use, and the cable was thick, but not frictionless.

  Wrapping his hands around the rope clipped to his belt, he pulled himself flush against it, and began shinning his way along the cable to a new world, towing his alien companion. After the briefest pause, Kretz pulled himself in and then, alien and human, they linked hands and pulled themselves towards what was slowly becoming down.

  The Brethren believed in the virtue of hard work, and by the time they reached the railings of the habitat, Howard was glad of it. It was hard to judge through the view plate of Kretz's suit, but the alien's grip had weakened on the last part. Howard would bet he was tired too. Still-their feet were down on the outside of whole new habitat. A new world!

  They un-clipped and began walking… Howard noticed that the disk on his sleeve now showed a thin band of green and was otherwise almost entirely red. If he understood it correctly that meant he had very little air left. He tried to walk a little faster. Then he noticed that Kretz-whose line had constantly pulled him forward on their walk to the cable, was lagging. Actually, the alien had stopped completely. Kretz staggered, almost pulling Howard from his upside-down stance. Now that he understood that the habitats spun on the cable, the feeling of being upside down was quite understandable. Logical, in fact. It was still uncomfortable, but he could see the railing of the catwalk ahead. It drew him like a magnet. Besides they were walking with the spin-it was less effort.

  Something in his helmet flashed red just above his eyes. At the top edge of the visor, Howard saw text appear, as if by a miracle.
