04-Protector Read online

  He was on a time limit. In thirty-two years Ttuss would reach the age of change. She would become an intelligent being, and a heavily armored one, with skin that would turn a copper knife and strength to lift ten times her own weight. She would be ideally designed for the purpose of fighting, but she would have nothing to fight for.

  She would stop eating. She would die, and Phssthpok would stop eating. Ttuss’s lifespan was his own.

  But sometimes a protector could adopt the entire Pak species as his descendants. At least he would have every opportunity to find a purpose in life. There was always truce for a childless protector, for such had no reason to fight. And there was a place he could go.

  The Library was as old as the radioactive desert which surrounded it. That desert would never be recultivated; it was reseeded every thousand years with radiocobalt so that no protector could covet it. Protectors could cross that desert; they had no gonadal genes to be smashed by subatomic particles. Breeders could not.

  How old was the Library? Phssthpok never knew, and never wondered. But the section on space travel was three million years old.

  He came to the Library with a number of—not friends, but associates in misery, childless former members of the Pitchok families. The Library was huge and rambling, a composite of at least three million years of Pak knowledge, crossfiled into sections according to subject. Naturally the same book often appeared in several sections. The associates divided at the entrance, and Phssthpok didn’t see any of them again for thirty-two years.

  He spent that time in one vast room, a floor-to-ceiling labyrinth of bookshelves. At scattered corners there were bins of tree-of-life root kept constantly filled by attendants. There were other foodstuffs brought at seeming random: meats, vegetables, fruits, whatever was available to childless protectors who had chosen to serve the Library rather than die. Tree-of-life root was the perfect food for a protector, but he could eat nearly anything.

  And there were books.

  They were nearly indestructible, those books. They would have emerged like fluttering meteors from the heart of a hydrogen fusion explosion. All were written more or less in the present language, and all were constantly being recopied by librarians as the language changed. In this room the books all dealt with space and space travel.

  There were treatises on the philosophy of space travel. They all seemed to make a fundamental assumption: someday the Pak race must find a new home; hence any contribution to the techniques of spaceflight contributed to the immortality of the species. Phssthpok could discount that assumption, knowing that a protector who did not believe it would never write a book on the subject. There were records of interstellar and interplanetary flights, tens of thousands of them, starting with a fantastic trip some group had made almost three million years ago, riding a hollowed-out asteroidal rock into the galactic arms in search of yellow dwarf suns. There were technical texts on anything that could possibly bear on space: spacecraft, astrogation, ecology, miniaturization, nuclear and subnuclear physics, plastics, gravity and how to use it, astronomy, astrophysics, records of the mining of worlds in this and nearby systems, diagrams for a hypothetical Bussard ramjet (in an unfinished work by a protector who had lost his appetite halfway through), ion drive diagrams, plasma theory, light-sails...

  He started at the left and began working his way around.

  He’d chosen the section on space travel more or less at random; it had looked less crowded than the others. The romance of space was not in Phssthpok’s soul. He kept with it rather than start over elsewhere. He might need every minute of his thirty-four years of grace no matter where be chose to work. In twenty-eight years he read every book in the Astronautics section, and still he had found nothing that drastically needed doing.

  Start a migration project? It simply wasn’t that urgent. The Pak sun had at least hundreds of millions of years to live... longer than the Pak species, probably, given the constant state of war. And the chance of disaster would be high. Yellow suns were scarce in the galactic core; they would have to travel far... with the protector crew constantly fighting for control of the ship. Come to that, the cores of galaxies could sometimes explode in a chain reaction of supernovae. A migration project really should travel into the arms.

  The first expedition to try that had met a horrible fate.

  So. Join the Library staff? He’d thought of it many times, but the answer always came out the same. No matter what phase of the Library he concerned himself with, his life would depend on others. To retain his will to live he would need to know that all Pak would benefit from his aspect of Library work. Let there be a dry spell in new discoveries, let his faith flag, and he would find himself no longer hungry.

  It was frightening not to be hungry. During the last few decades it had happened several times. Each time he would force himself to reread the communications from the Valley of Pitchok. The latest communication always told him that Ttuss bad been alive when it was sent. Gradually his appetite would come back. Without Ttuss he would be dead.

  He had investigated the librarians. Their lives were usually short. Joining the staff was no answer.

  Find a way to keep Ttuss alive? If he could do that he would have used the method on himself.

  Study theoretical astronomy? He had some ideas, but they would not help the Pak species. The Pak did not seek abstract knowledge. Mine the asteroids? The asteroids of this and nearby stars were as thoroughly mined out as the surface of the planet had often been, with the difference that convection currents in the planet’s interior eventually replaced worked-out mines. He should have gone in for metal reclamation. Now it was too late to change studies. Put plastic-bubble cities in orbit to provide more living room for breeders? Nonsense: too vulnerable to capture or accidental destruction.

  One day Phssthpok’s appetite was gone. The letters from the Valley of Pitchok did not help; he didn’t believe them. He thought of returning to the valley, but he knew he would starve to death on the way. When he was sure, he sat down against a wall, the last in a line of protectors who also did not eat, who were waiting to die.

  A week passed. The librarians found that two at the head of the line were dead. They picked them up, a pair of skeletons clothed in dry, wrinkled leather armor, and carried them away.

  Phssthpok remembered a book.

  He still had the strength to reach it.

  He read carefully, with the book in one hand and a root in the other. Presently he ate the root...

  The ship had been a roughly cylindrical asteroid, reasonably pure nickel-iron with stony strata running through it, about six miles long and four through. A group of childless protectors had carved it out with solar mirrors and built into it a small life-support and controls system, a larger frozen-sleep chamber, a breeder atomic pile and generator, a dirigible ion drive, and an enormous cesium tank. They had found it necessary to exterminate the protectors of a large family in order to get control of a thousand breeders. With two protectors as pilots and seventy more in frozen sleep with the thousand breeders, with a careful selection of the beneficial lifeforms of the Pak world, they set out into one arm of the galaxy.

  Though their knowledge was three million years scantier than Phssthpok’s, they had good reason for choosing the galaxy’s outer reaches. They’d have a better chance of finding yellow suns out there, and a better chance to find a double planet at the right distance. Perturbations from stars an average of half a light year apart made double planets scarce in the galactic core; and there was reason to think that only an oversized moon could give any world an atmosphere capable of supporting Paklike life.

  An ion drive and a certain amount of cesium... They expected to move slowly, and they did. At twelve thousand miles per second relative to the Pak sun, they coasted. They fired a laser message back at the Pak sun to tell the Library that the ion drive had worked. The blueprints were somewhere in the Library, with a list of suggested design changes.

  Phssthpok was not interested. He mov
ed on to the last section, which was nearly half a million years more recent.

  It was a record of a laser message that had come plowing through the Pak system, torn and attenuated and garbled by dust clouds and distance, in a language no longer spoken. The librarians had translated it and filed it here. It must have been retranslated hundreds of times since then. Hundreds of searchers like Phssthpok must have read it, and wondered about the part of the story they could never know, and passed on...

  But Phssthpok read it very carefully.

  They had traveled deep into the galactic arms. Half the protectors had been gone at journey’s end, dying not of starvation or violence but of age. This was so unusual that a detailed medical description had been included as part of the message. They had passed yellow suns with no planets, others whose worlds were all gas giants. Yellow suns had gone by carrying worlds that might have been habitable; but all were too far off course to be reached on the maneuvering reserve of cesium. Galactic dust and the galaxy’s gravity had slowed their strange craft, increasing their maneuver reserve. The sky had darkened around them as suns became rare.

  They had found a planet.

  They had braked the ship. They had transferred what was left of the plutonium to the motors of landing craft, and gone down. The decision was not final; but if the planet failed to measure up they would have to work for decades to make their rockship spaceworthy again.

  It had life. Some was inimical, but none that could not be handled. There was soil. The remaining protectors woke the breeders and turned them loose in the forests to be fruitful and multiply. They planted crops, dug mines, made machines to dig more mines, made machines to tend crops...

  The black, nearly starless night sky bothered some, but they got used to it. The frequent rains bothered others, but did not hurt the breeders, so that was all right. There was room for all; the protectors did not even fight. None stopped eating. There were predators and bacteria to exterminate, there was a civilization to build, there was much to do.

  With spring and summer came crops—and disaster. There was something wrong with the tree-of-life.

  The colonists themselves did not understand what had gone wrong with the crop. Something had come up. It looked and tasted like tree-of-life, though the smell was wrong, somehow. But for all its effect on breeders and protectors alike, they might as well have been eating weeds.

  They could not return to space. Their scant remaining store of roots represented an inflexible number of protector work-hours. They might refuel their cesium tanks, they might even build a plutonium-producing technology in the time they had left, but to find and reach another Pak-like world—no. And if they reached it, what guarantee had they that it would grow tree-of-life?

  They had spent their last years building a laser beam powerful enough to pierce the dust clouds that hid them from the galactic core. They did not know that they had succeeded. They did not know what was wrong with the crop; they suspected the sparsity of a particular wavelength of starlight, or of starlight in general, though their experiments along those lines had produced nothing. They gave detailed information on the blood lines of their breeder passengers, in the hope that some of the lines might survive. And they asked for help.

  Two and a half million years ago.

  Phssthpok sat by the root bin, eating and reading. He would have smiled if his face had been built that way. Already he could see that his mission would involve every childless protector in the world.

  For two and a half million years those breeders had been living without tree-of-life. Without any way to make the change to the protector stage. Dumb animals.

  And Phssthpok alone knew how to find them.

  You’re flying from New York, USA, to Piquetsburg, North Africa. Suddenly you become aware that New York is flying in one direction, Piquetsburg in another, and a hurricane wind is blowing your plane off course in still a third...

  Nightmare? Well, yes. But travel in the solar system is different from travel on a planet. Each individual rock moves at its own pace, like flecks of butter in a churn.

  Mars moved in a nearly circular path. Asteroids moved nearby in orbits more elliptical, catching up to the red planet or falling behind. Some carried telescopes. Their operators would report to Ceres if they saw purposeful action on the surface.

  The abandoned Bussard ramjet crossed over the sun and curved inward, following a shallow hyperbola which would take it through the plane of the planets.

  The Blue Ox followed an accelerating higher-order curve, a J whose upright would eventually match the Ox’s velocity and position to the Outsiders.

  U Thant rose from Earth on a ram-and-wing rented from Death Valley Port. There was a lovely scenic ride up and out over the Pacific. One hundred and fifty miles up and orbiting, as required by law, Nick switched to fusion power and headed outward. He left the ram-and-wing to find its own way home.

  The Earth wrapped itself around itself and dropped away. It was four days to Mars at one gee, with Ceres to tell them which asteroids to dodge.

  Nick put the ship on autopilot. He was not entirely displeased with the U Thant. It was a flatlander navy job, its functions compromised by streamlining; but the equipment seemed adequate and the controls were elegantly simple. And the kitchen was excellent.

  Luke said, “Okay to smoke?”

  “Why not? You can’t be worried about dying young.”

  “Does the UN have its money yet?”

  “Sure. They must have got it transferred hours ago.”

  “Fine. Call them, identify yourself, and ask for everything they’ve got on Mars. Tell them to put it on the screen, and you’ll pay for the laser. That’ll kill two birds with one stone.”

  “How?”

  “It’ll tell them where were going.”

  “Right... Luke, do you really think this will get them moving? I know how unwieldy the UN is. There was the Müller case.”

  “Look at it from another direction, Nick. How did you come to represent the Belt?”

  “Aptitude tests said I had a high IQ and liked ordering people around. From there I worked my way up.”

  “We go by the vote.”

  “Popularity contests.”

  “It works. But it does have drawbacks. What government doesn’t?” Garner shrugged. “Every speaker in the UN represents one nation—one section of the world. He thinks it’s the best section, filled with the best people. Otherwise he wouldn’t have been elected. So maybe twenty representatives each think they know just what to do about the Outsider, and no one of them will knuckle down to the others. Prestige. Eventually they’d work out a compromise. But if they get the idea that a civilian and a Belter could beat them to the Outsider, they’ll get off their thumbs faster. See?”

  “No.”

  “Oh, make your call.”

  A message beam found them some time later. They began to skim Earth’s stored information on Mars.

  There was quite a lot of it. It covered centuries. At one point Nick said, “I’m ready for summer vacation. Why do we have to watch all this? According to you we’re just running a bluff.”

  “According to me we’re running a search, unless you have something better to do. The best time to bluff is with four aces.”

  Nick switched off the screen. The lecture was on tape now; they wouldn’t miss anything. “Come, let us reason together. I paid a million marks in Belt funds for this stuff, plus additional charges for the message beam. Thrifty Sohl that I am, I feel almost compelled to use it. But we’ve been studying the Müller case for the past hour, and it all came out of Belt files!”

  Eleven years ago a Belt miner named Müller had tried to use the mass of Mars to make a drastic course change. He had come too close; had been forced to land. There would have been no problem. The goldskin cops would have picked him up as soon as they had clearance from the UN. No hurry... until Müller was murdered by martians.

  Martians had been a myth until then. Müller must have been amazed. But
, strangling in near-vacuum, he had managed to kill half a dozen of them, using a water tank to spray death in all directions.

  “Not all of it. We were the ones who studied the martian corpses you recovered,” said Garner. “We may need that information. I’m still wondering why the Outsider picked Mars. Maybe he knows about martians. Maybe he wants to contact them.”

  “Much good may it do him.”

  “They use spears. By me that makes them intelligent. We don’t know how intelligent, because nobody’s ever tried to talk to a martian. They could have any kind of civilization you can imagine, down there under the dust.”

  “A civilized people, are they?” Nick’s voice turned savage. “They slashed Müller’s tent! They let his air out!” In the Belt there is no worse crime.

  “I didn’t say they were friendly.”

  The Blue Ox coasted. Behind her the alien ship was naked-eye visible and closing. It made Tina nervous to be unable to watch it. But that could work two ways; and this was the Outsider’s blind side, where three Belters worked to free Einar Nilsson’s singleship from its vast metal uterus.

  “Clamps free back here,” said Tina. She was sweating. She felt the breeze on her face, as the air system worked to keep her faceplate from fogging.

  Nate’s voice spoke behind her ear. “Good, Tina.”

  Einar’s said, “We could have carried a fourth crewman in the singleship's lifesystem. Damn! I wish I’d thought of it. There’d be two of us to meet the Outsider.”

  “It probably won’t matter. The Outsider’s gone. That’s a dead ship.” Nonetheless Nate sounded uneasy.

  “And how many crew got left behind? I never much believed the Outsider would come riding between the stars alone in a singleship. Too poetic. Never mind. Tina, give us five seconds of thrust under the fusion tube.”

  Tina set her shoulders and fired her backpac jets. Other flames sprouted forward under the lifesystem hull. The old singleship drifted slowly up between the great doors.
