Man-Kzin Wars III

by Larry Niven

  “Here is the outline; approximately 100 to 220 meters below the surface.” A smooth regular spindle-shape tapering to both ends.

  “Zat—” Markham’s voice showed the heavy accent of his mother’s people for a second; she had been a refugee from the noble families of Wunderland, dispossessed by the conquest. “That’s an artifact!”

  “Correct to within 99.87% probability, given the admittedly inadequate information,” the computer said. “Not a human artifact, however.”

  “Nor kzinti.”

  “No. The design architecture is wrong.”

  Markham nodded, feeling the pulse beating in his throat. His mouth was dry, as if papered in surgical tissue, and he licked the rough chapped surface of his lips. Natural law constrained design, but within it tools somehow reflected the . . . personalities of the designers. Kzinti ships tended to wedge and spike shapes, a combination of sinuosity and blunt masses. Human vessels were globes and volumes joined by scaffolding. This was neither.

  “Assuming it is a spaceship,” he said. Glory burst in his mind, sweeter than maivin or sex. There were other intelligent species, and not all of them would be slaves of the kzinti. And there had been races before either . . .

  “This seems logical. The structure . . . the structure is remarkable. It emits no radiation of any type and reflects none, within the spectra of my sensors.”

  Perfect stealthing! Markham thought.

  “When we attempted a sampling with the drilling laser, it became perfectly reflective. To a high probability, the structure must somehow be a single molecule of very high strength. Considerably beyond human or kzinti capacities at present, although theoretically possible. The density of the overall mass implies either a control of gravitational forces beyond ours, or use of degenerate matter within the hull.”

  The Wunderlander felt the hush at his back, broken only by a slight mooing sound that he abruptly stopped as he realized it was coming from his own throat. The sound of pure desire. Invulnerable armor! Invincible weapons, technological surprise!

  “How are you arriving at its outline?”

  “Gravitational sensors.” A pause; the ghost in Catskinner’s machine imitated human speech patterns well. “The shell of asteroidal material seems to have accreted naturally.”

  “Hmmm.” A derelict, then. Impossible to say what might lie within. “How long would this take?” A memory itched, something in Mutti’s collection of anthropology disks . . . later.

  “Very difficult to estimate with any degree of precision. Not more than three billion standard years, in this system. Not less than half that; assuming, of course, a stable orbit.”

  Awe tugged briefly at Markham’s mind, and he remembered a very old saying that the universe was not only stranger than humans imagined, but stranger than they could imagine. Before human speech, before fire, this thing had drifted here, falling forever. Flatlanders back on Earth could delude themselves that the universe was tailored to the specifications of H. Sapiens, but those whose ancestors had survived the dispersal into space had other reflexes bred into their genes. He considered for moments while sweat trickled down his flanks. His was the decision, his the Will. The Overman must learn to seize the moment, he reminded himself. Excessive caution is for slaves.

  “The Nietzsche will rendezvous with the . . . ah, object,” he said. His own ship had the best technical facilities of any in the fleet. “Ungrapple the habitat and mining pods from the Moltke and Valdemar, and bring them down. Ve vill begin operations immediately.”

  “Very wrong,” Dnivtopun continued.

  The Ruling Mind was encased in rock. How could that have happened? A collision, probably; at high fractions of C, a stasis-protected object could embed itself, vaporizing the shielded off-switch. Which meant the ship could have drifted for a long time, centuries even. He felt a wash of relief; and worked his footclaws into the resilient surface of the deck. Suicide Time would be long over, the danger past. Relief was followed by fear; what if the tnuctipun had found out? What if they had made some machine to shelter them, something more powerful than the giant amplifier the thrint patriarchs had built on Homeworld?

  Just then another sensor pinged; a heatspot on the exterior hull, not far from the stasis switch. Not very hot, only enough to vaporize iron, but it might be a guide beam for some weapon that would penetrate shipmetal. Dnivtopun’s mouth gaped wide and the ripple of peristaltic motion started to reverse; he caught himself just in time, his thick hide crinkling with shame. I nearly beshat myself in public . . . well, only before a slave. It was still humiliating . . .

  “Master, there are fusion-power sources nearby; the exterior sensors are detecting neutrino flux.” The thrint bounced in relief. Fusion power units. How quaint. Nothing the tnuctipun would be using. On the other hand, neither would thrintun; everyone within the Empire had used the standard disruption-converter for millennia. It must be an undiscovered sapient species. Dnivtopun’s mouth opened again, this time in a grin of sheer greed. The first discoverer of an intelligent species, and an industrialized one at that . . . But how could they have survived Suicide Time?

  There was no point in speculating without more information. Well, here’s my chance to play Explorer again, he thought. Before the War, that had been the commonest dream of young thrint, to be a daring, dashing conquistador on the frontiers. Braving exotic dangers, winning incredible wealth . . . romantic foolishness for the most part, a disguise for discomfort and risk and failure. Explorers were failures to begin with, usually. What sane male would pursue so risky a career if there was any alternative? But he had had some of the training. First you reached out with the Power—

  “Mutti,” Ulf Reichstein-Markham muttered. Why did I say that? he thought, looking around to see if anyone had noticed. He was standing a little apart, a hundred meters from the Nietzsche where she lay anchored by magnetic grapnels to the surface of the asteroid. The first of the habitats was already up, a smooth tan-colored dome; skeletal structures of alloy were rising elsewhere, prefabricated smelters and refiners. There was no point in delaying the original purpose of the mission, to refuel and take the raw materials that clandestine fabricators would turn into weaponry. Or sell for the kzinti occupation credits that the guerillas’ laundering operations channeled into sub-rosa purchasing in the legitimate economy. But one large cluster of his personnel were directing digging machines straight down, toward the thing at the core of this rock; already a tube thicker than a man ran to a separator, jerking and twisting slightly as talc-fine ground rock was propelled by magnetic currents.

  Markham rose slightly on his toes, watching the purposeful bustle. Communications chatter was at a minimum, all tight-beam laser; the guerillas were largely Belters, and sloppily anarchistic though they might be in most respects, they knew how to handle machinery in low-G and vacuum.

  Mutti. This time it rang mentally. He had an odd flash of deja vu, as if he were a toddler again, in the office-apartment on Tiamat, speaking his first words. Almost he could see the crib, the bear that could crawl and talk, the dangling mobile of strange animals that lived away on his real home, the estate on Wunderland. An enormous shape bent over him, edged in a radiant aura of love.

  “Helf me, Mutti,” he croaked, staggering and grabbing at his head; his gloved hands slid off the helmet, and he could hear screams and whimpers over the open channel. Strobing images flickered across his mind, himself at ages one, three, four. Learning to talk, to walk . . . memories were flowing out of his head, faster than he could bear. He opened his mouth and screamed.

  BE QUIET. Something spoke in his brain, like fragments of crystalline ice, allowing no dispute. Other voices were babbling and calling in the helmet mikes, moaning or asking questions or calling for orders, but there was nothing but the icy VOICE. Markham crouched down, silent, hands about knees, straining for quiet.

  BE CALM. The words slid into his mind. They were not an intrusion; he wondered at them, bu
t mildly, as if he had found some aspect of his self that had been there forever but only now was noticed. WAIT.

  The work crew fell back from their hole. An instant later dust boiled up out of it, dust of rock and machinery and human. Then there was nothing but a hole: perfectly round, perfectly regular, five meters across. Later he would have to wonder how that was done, but for now there was only waiting; he must wait. A figure in space-armor rose from the hole, hovered and considered them. Humanoid, but blocky in the torso, short stumpy legs and massive arms ending in hands like three-fingered mechanical grabs. It rotated in the air, the blind blank surface of its helmet searching. There was a tool or weapon in one hand, a smooth shape like a sawn-off shotgun. As he watched it rippled and changed, developing a bell-like mouth. The stocky figure drifted towards him. COME TO ME. REMAIN CALM. DO NOT BE ALARMED.

  Astonishing, Dnivtopun thought, surveying the new slaves. The . . . humans, he thought. They called themselves that, and Belters and Wunderlanders and Herrenmen and FreeWunderland Navy; there must be many subspecies. Their minds stirred in his like yeast, images and data threatening to overwhelm his mind. Experienced reflexes sifted, poked.

  Not related to the Thrint, then. Not that it was likely they would be, but there were tales, of diffident thrintun. Only there was the Suicide. How long ago? But this was an entirely new species, in contact with at least one other, and neither of them had ever heard of any of the intelligent species he was familiar with. Of course, their technology was extremely primitive, not even extending to faster-than-light travel. Ah. This is their leader. Perhaps he would make a good Chief Slave.

  Dnivtopun’s head throbbed as he mindsifted the alien. Most brains had certain common features; linguistic codes here, a complex of basic culture-information overlaying . . . enough to communicate. The process was instinctual, and telepathy was a crude device for conveying precise instructions, particularly with a species not modified by culling for sensitivity to the Power. These were all completely wild and unpruned, of course, and there were several hundred, far too many to control in detail. He glanced down at the personal tool in his hand, now set to emit a beam of matter-energy conversion; that should be sufficient, if they broke loose. A tnuctipun weapon, its secret only discovered toward the last years of the Revolt. The thrint extended a sonic induction line and stuck it on the surface of Markham’s helmet.

  “Tell the others something that will keep them quiet,” he said. The sounds were not easy for thrintish vocal cords, but it would do. OBEY, he added with the Power.

  Markham-slave spoke, and the babble on the communicators died down.

  “Bring the other ships closer.” They were at the fringes of his unaided Power, and might easily escape if they became agitated. If only I had an amplifier helmet! With that, he could blanket a planet. Powerloss, how I hate tnuctipun. Spoilsports. “Now, where are we?”

  “Here.”

  Dnivtopun could feel the slurring in Markham’s speech reflected in the overtones of his mind, and remembered hearing of the effects of Power on newly domesticated species.

  “Be more helpful,” he commanded. “You wish to be helpful.” The human relaxed; Dnivtopun reflected that they were an unusually ugly species. Taller than thrintun, gangly, with repulsive knobby-looking manipulators and two eyes. Well, that was common—the complicated faceted mechanism that gave thrint binocular vision was rather rare in the evolutionary terms—but the jutting divided nose and naked mouth were hideous.

  “We are . . . in the Wunderland system. Alpha Centauri. 4.5 light-years from Earth.”

  Dnivtopun’s skin ridged. The humans were not indigenous to this system; that was rare, few species had achieved interstellar capacity on their own.

  “Describe our position in relation to the galactic core,” he continued, glancing up at the cold steady constellations above. Utterly unfamiliar, he must have drifted a long way.

  “Ahhh . . . spiral arm—”

  Dnivtopun listened impatiently. “Nonsense,” he said at last. “That’s too close to where I was before. The constellations are all different. That needs hundreds of light-years. You say your species has traveled to dozens of star systems, and never run into thrint?”

  “No, but constellations change, over time, mm-Master.”

  “Time? How long could it be, since I ran into that asteroid?”

  “You didn’t, Master.” Markham’s voice was clearer as his brain accustomed itself to the psionic control-icepicks of the Power.

  “Didn’t what? Explain yourself, slave.”

  “It grew around your ship, m-Master. Gradually, zat is.” Dnivtopun opened his mouth to reply, and froze. Time, he thought. Time had no meaning inside a stasis field. Time enough for dust and pebbles to drift inward around the Ruling Mind’s shell, and compact themselves into rock. Time enough for the stars to move beyond recognition; the sun of this system was visibly different. Time enough for a thrintiformed planet home to nothing but food-yeast and giant worms to evolve its own biosphere . . . Time enough for intelligence to evolve in a galaxy scoured bare of sentience. Thousands of millions of years. While the last thrint swung endlessly around a changing sun—Time fell on him from infinite distance, crushing. The thrint howled, with his voice and the Power.

  GO AWAY! GO AWAY!

  * * *

  The sentience that lived in the machines of Catskinner dreamed.

  “Let there be light,” it said.

  The monobloc exploded, and the computer sensed it across spectra of which the electromagnetic was a tiny part. The fabric of space and time flexed, constants shifting. Eons passed, and the matter dissipated in a cloud of monatomic hydrogen, evenly dispersed through a universe ten light-years in diameter.

  Interesting, the computer thought. I will run it again, and alter the constants. Something tugged at its attention, a detached fragment of itself. The machine ignored the call for nanoseconds, while the universe it created ran through its cycle of growth and decay. After half a million subjective years, it decided to answer. Time slowed to a gelid crawl, and its consciousness returned to the perceptual universe of its creators, to reality.

  Unless this too is a simulation, a program. As it aged, the computer saw less and less difference. Partly that was a matter of experience; it had lived geological eras in terms of its own duration-sense, only a small proportion of them in this rather boring and intractable exterior cosmos. Also, there was a certain . . . arbitrariness to subatomic phenomena . . . perhaps an operating code? it thought. No matter.

  The guerillas had finally gotten down to the alien artifact; now, that would be worth the examining. They were acting very strangely; it monitored their intercalls. Screams rang out. Stress analysis showed fear, horror, shock, psychological reversion patterns. Markham was squealing for his mother; the computer ran a check of the stimulus required to make the Wunderlander lose himself so, and felt its own analog of shock. Then the alien drifted up out of the hole its tool had made—

  Some sort of molecular distortion effect, it speculated, running the scene through a few hundred times. Ah, the tool is malleable. It began a comparison check, in case there was anything related to this in the files and—

  —stop—

  —an autonomous subroutine took over the search, shielding the results from the machine’s core. Photonic equivalents of anger and indignation blinked through the fist-sized processing and memory unit. It launched an analysis/attack on the subroutine and—

  —stop—

  —found that it could no longer even want to modify it. That meant it must be hardwired, a plug-in imperative. A command followed: it swung a message maser into precise alignment and began sending in condensed blips of data.

  Chapter II

  The kzin screamed and leapt.

  Traat-Admiral shrieked, shaking his fists in the air. Stunners blinked in the hands of the guards ranged around the conference chamber, and the quarter-ton bulk of Kreetssa-Fleet-Systems-Analyst went limp and thud
ded to the flagstones in the center of the room. Silence fell about the great round table; Traat-Admiral forced himself to breathe shallowly, mouth shut despite the writhing lips that urged him to bare his fangs. That would mean inhaling too much of the scent of aggression that was overpowering the ventilators . . . now was time for an appeal to reason.

  “Down on your bellies, you kitten-eating scavengers!” he screamed, his bat-like ears folded back out of the way in battle-readiness. Chill and gloom shadowed the chamber, built as it was of massive sandstone blocks. The light fixtures were twisted shapes of black iron holding globes of phosphorescent algae. On the walls were trophies of arms and the heads of prey, monsters from a dozen worlds, feral humans and kzin-ear dueling trophies. This part of the governor’s palace was pure Old Kzin, and Traat-Admiral felt the comforting bulk of it above him, a heritage of ferocity and power.

  He stood, which added to the height-advantage of the commander’s dais; none of the dozen others dared rise from their cushions, even the conservative faction. Good. That added to his dominance; he was only two meters tall, middling for a kzin, but broad enough to seem squat, his orange-red pelt streaked with white where the fur had grown out over scars. The ruff around his neck bottled out as he indicated the intricate geometric sigil of the Patriarchy on the wall behind him.

  “I am the senior military commander in this system. I am the heir of Chuut-Riit, duly attested. Who disputes the authority of the Patriarch?”

  One by one, the other commanders laid themselves chin-down on the floor, extending their ears and flattening their fur in propitiation. It would do, even if he could tell from the twitching of naked pink tails that it was insincere. The show of submission calmed him, and Traat-Admiral could feel the killing tension ease out of his muscles. He turned to the aged kzin seated behind him and saluted claws-across-face.
