Satan's World

  At full pseudospeed, from the nameless star to the sun of Dathyna took a bit under a week. The prisoner ship must strain to keep pace with the warcraft that surrounded her. But she succeeded, which told Earthman and Wodenite something about Shenn space capabilities.

  They gathered quite a few other facts en route. This did not include the contents of Gahood’s message, nor the reason why it sent the team plunging immediately homeward. But their captors questioned them at irregular intervals, by hypercom. The interrogation was unsystematic and repetitive, seemingly carried out whenever some individual Shenn got the impulse, soon degenerating into boasts and threats. Van Rijn gave many truthful answers, because the aliens could generally have obtained them directly from Thea—population, productivity, et cetera of the major Technic worlds; nature and activities of the Polesotechnic League; picturesque details about this or that life form, this or that culture—She was plainly distressed at the behavior of her lords, and tried to recast their words into something better organized. By playing along with her, van Rijn was able to draw her out. For example:

  “Lord Nimran wants to hear more about the early history of Earth,” she told the merchant. Computers on either vessel converted between dot-dash transmission and voice. “He is especially interested in cases where one civilization inherited from another.”

  “Like Greeks taking over from Minoans, or Western Christendom from Roman Empire, or Turks from Byzantines?” van Rijn asked. “Cases are not comparable. And was long ago. Why should he care?”

  He could imagine how she flushed. “It suffices that he does care.”

  “Oh, I don’t mind making lectures at him. Got nothings else to do except pour me another beer. Speaking about which—” Van Rijn leaned over and fumbled in the cooler that Adzel had carried to the bridge for him. “Ah, there you are, fishie.”

  The computer turned this into hyperimpulses. The receiving computer was not equipped to translate, but its memory bank now included an Anglic vocabulary. Thea must have told Nimran that he had not properly replied. Did the minotaur growl and drop hand to gun? Her plea was strained through the toneless artificial voice: “Do not provoke him. They are terrible when they grow angry.”

  Van Rijn opened the bottle and poured into a tankard. “Ja, sure, sure. I only try for being helpful. But tell him I got to know where he wants his knowledge deepened before I can drill in the shaft. And why. I feel the impression that Shenn culture does not produce scientists what wants to know things from pure curiosity.”

  “Humans overrate curiosity. A monkey trait.”

  “Uh-huh, uh-huh. Every species got its own instincts, sometimes similar at some other race’s but not necessary so. I try now to get the basic instinct pattern for your . . . owners . . . because elsewise what I tell them might not be what they want, might not make any sense to them whatsomever. Hokay, you tell me there is no real science on Dathyna. No interest in what isn’t practical, or edible, or drinkable (Aaahhh!), or salable, or useful in other ways I should not mention to a lady.”

  “You oversimplify.”

  “I know. Can’t describe one single individual being in a few words, let alone a whole intelligent race. Sure. But speaking rough, have I right? Would you say this society is not one for abstracted science and odd little facts what aren’t relevancy right away?”

  “Very well, agreed.” There came a pause, during which Thea was probably calming Nimran down again.

  Van Rijn wiped foam off his nose and said: “I collect from this, is only one Shenn civilization?”

  “Yes, yes. I must finish talking to him.” After a couple of minutes: “If you do not start answering, the consequences may be grave.”

  “But I told you, sweetling, I’m not clear what is his question. He has not got a scientific curiosity, so he asks about successions of culture on Earth because might be is something useful to his own recent case on Dathyna. True?”

  After hesitation: “Yes.”

  “All right, let us find out what kind of succession he is interested in. Does he mean how does a supplanter like Hindu appear, or a hybrid like Technic or Arabic, or a segue of one culture into another like Classical into Byzantine, or what?”

  No doubt forlornness crossed her eyes. “I don’t know anything myself about Earth’s history.”

  “Ask him. Or better I should ask him through you.”

  In this manner, van Rijn got confirmation of what he suspected. The Shenna had not created the magnificent cybernetic structure they used. They took it over from an earlier race, along with much else. Still more appeared to have been lost, for the Shenna were conquerors, exterminators, savages squatting a house erected by civilized beings whom they had murdered. (How was this possible?)

  They were not less dangerous on that account, or because they were herbivorous. (What kind of evolution could produce warlike herbivores?)

  They had the wit to heed the recommendation of the Serendipity computer as regards the planet at Beta Crucis. They could see its industrial potential. But they were more concerned with denying this to others than with making intensive use of it themselves. For they were not traders or manufacturers on any significant scale. Their robots produced for them the basic goods and services they required, including construction and maintenance of the machinery itself. They had no desire for commercial or intellectual relations with Technic societies. Rather, they believed that coexistence was impossible. (Why?)

  The Serendipity operation typefied them. When they first happened upon other races that traveled and colonized through space, out on the fringe of the existing Technic sphere, they proceeded to study these. Their methods were unspecified, and doubtless varied from place to place and time to time, but need not always have been violent. A Shenn could be cunning. Since no one can remember all the planets whose natives may go a-roving, he need not admit he came from Outside, and he could ask many natural-sounding questions.

  Nevertheless, they could not secretly get the detailed information they wanted by such hit-and-run means. One brilliant male among them conceived the idea of establishing spies in the heart of the other territory: spies who could expect the eager cooperation of their victims. His fellows agreed to help start the enterprise. No Shenn had the patience to run that shop in Lunograd. But computers did.

  Even so, the basic program for the machines and doctrine for the people were drawn up by Shenna. And here the nature of the beast again revealed itself. When something important and urgent comes up, react aggressively—fast! Most species would have given an agency more caution, more flexibility. The Shenna could not endure to. Their instinct was such that to them, in any crisis, action was always preferable to wait-and-see. The pieces could be picked up later.

  The Shenna did have a rationale for their distrust of other spacegoing races. (Which distrust automatically produced murderous hatred in them.) They themselves were not many. Their outplanet colonies were few, small, and none too successful. Four-fifths of their adults must be counted out as significant help—because the females outnumbered the polygynous males by that fraction, and were dullbrained subservient creatures. Their political structure was so crude as to be ridiculous. Baronial patriarchs, operating huge estates like independent kingdoms, might confer or cooperate at need, on a strictly voluntary basis; and this constituted the state. Their economics was equally primitive. (How had a race like this gone beyond the Paleolithic, let alone destroyed another people who had covered the planet with machines and were reaching for the stars?)

  The companies of the League could buy and sell them for peanuts. The outward wave of Technic settlement would not necessarily sweep over them when it got that far—why bother?—but would certainly engulf every other desirable world around Dathyna. At best, with enormous effort, the Shenna might convert themselves into one more breed of spacefarers among hundreds. To natures like theirs, that prospect was intolerable.

  However their society was describable, they were not ridiculous themselves. On t
he contrary, they were as ominous as the plague bacillus when first it struck Europe. Or perhaps more so; Europe did survive.

  The sun of Dathyna looked familiar to Adzel—middle F-type, 5.4 times as luminous as Sol, white more than gold—until he studied it with what instruments he had available. Astonished, he repeated his work, and got the same results. “That is not a normal star,” he said.

  “About to go nova?” van Rijn asked hopefully.

  “No, not that deviant.” Adzel magnified the view, stepping down the brilliance, until the screen showed a disk. The corona gleamed immense, a beautiful serene nacre; but it was background for the seething of flares and prominences, the dense mottling of spots. “Observe the level of output. Observe likewise the intricate patterns. They show a powerful but inconstant magnetic field . . . Ah.” A pinpoint of eye-hurting light flashed and died on the surface. “A nuclear explosion, taking place within the photosphere. Imagine what convection currents and plasma effects were required. Spectroscopy is consistent with visual data, as is radiation metering. Even at our present distance, the solar wind is powerful; and its pattern as we move inward is highly changeable.” He regarded the scene with his rubbery lips pulled into an alarming smile. “I had heard of cases like this, but they are rare and I never thought I would have the good fortune to see one.”

  “I’m glad you get fun out of now,” van Rijn grumbled. “Next funeral I attend, I want you along for doing a buck-and-wing while you sing ‘Hey nonny nonny.’ So what we got here?”

  “A sun not only massive, but of unusual composition, extremely rich in metals. Probably it condensed in the neighborhood of a recent supernova. Besides the normal main-sequence evolution, a number of other fusion chains, some of which terminate in fission, go on during its life. This naturally influences interior phenomena, which in turn determine the output. Consider it an irregularly variable star. It isn’t really, but the pattern is so complex that it does not repeat within epochs. If I interpret my findings correctly, it is at present receding from a high peak which occurred—zanh-h-h, several thousand years ago, I would guess.”

  “But did not wipe out life on Dathyna?”

  “Obviously not. The luminosity will never become that great, until the sun leaves the main sequence altogether. Nevertheless, there must have been considerable biological effect, especially since the charged-particle emission did reach an extreme.”

  Van Rijn grunted, settled deeper in his chair, and reached for his churchwarden. He usually smoked it when he wanted to think hard.

  The flotilla approached Dathyna. The computer of the captive ship kept all sensors open as instructed, and reported much activity in surrounding space—ships in orbit, ships coming and going, ships under construction. Adzel took readings on the globe itself.

  It was the fourth one out from its sun, completing a period of 2.14 standard years at a mean distance of two a.u. in mass it likewise resembled Mars: 0.433 Terrestrial, the diameter only 7,950 kilometers at the equator. Despite this, and a third again the heat and light which Earth receives, Dathyna had an extensive oxynitrogen atmosphere. Pressure dropped off rapidly with altitude, but at sea level was slightly greater than Terrestrial. Such an amount of gas was surely due to the planetary composition, an abundance of heavy elements conferring an overall specific gravity of 9.4 and thus a surface acceleration of 1,057 cm/sec2. The metal-rich core must have produced enormous outgassing through vulcanism in the world’s youth. Today, in combination with the fairly rapid spin—once around in seventeen and a quarter hours—it generated a strong magnetic field which screened off most of the solar particles that might otherwise have kicked air molecules free. The fact was also helpful that Dathyna had no moons.

  Visually, swelling upon blackness and stars, the planet was equally strange. It had far less hydrosphere then Earth; quanta from the ultraviolet-spendthrift sun had split many a water molecule. But because mountains and continental masses were less well defined, the surface flatter on the average, water covered about half. Shallow, virtually tideless, those seas were blanketed with algalike organisms, a red-brown-yellow mat that was sometimes ripped apart to show waves, sometimes clotted into floating islands.

  With slight axial tilt and comparatively small edge effect, the polar regions did not differ spectacularly from the equatorial. But with a steep air pressure gradient, the uplands were altogether unlike the valleys beneath—were glacier and naked rock. Some lowlands, especially along the oceans, appeared to be fertile. The brownish-gold native vegetation colored them; forests, meadows, croplands showed in the magniscreen. But enormous regions lay desert, where dust storms scoured red rock. And their barrenness was geologically new—probably not historically too old—because one could identify the towers and half buried walls of many great dead cities, the grid of highways and power pylons that a large population once required.

  “Did the sun burn the lands up when it peaked?” For once, van Rijn almost whispered a question.

  “No,” Adzel said. “Nothing that simple, I think.”

  “Why not?”

  “Well, increased temperature would cause more evaporation, more clouds, higher albedo, and thus tend to control itself. Furthermore, while it might damage some zones, it would benefit others. Life should migrate poleward and upward. But you can see that the high latitudes and high altitudes have suffered as badly as any place. Then too, a prosperous, energetic machine culture ought to have found ways of dealing with a mere change in climate—a change which did not come about overnight, remember.”

  “Maybe they held a war what got rough?”

  “I see no signs of large-scale misuse of nuclear energies. And would any plausible biological or chemical agents wreck the entire ecology of an entire planet, right down to the humble equivalents of grass? I think,” said Adzel grimly, “that the catastrophe had a much larger cause and much deeper effects.”

  He got no chance to elaborate then, for the ship was ordered into atmosphere. A pair of destroyers accompanied. Moath and Thea directed the robots from a tender. The group landed near the Shenn’s ancestral castle. An armed swarm ran forth to meet them.

  In the next three days, van Rijn and Adzel were given a look around. Thea guided them. “My lord permits this on my recommendation, while he is away at the Grand Council that’s been called,” she said. “By giving you a better comprehension of our society, we make you better able to help us with information.” Pleadingly, not meeting their eyes: “You will help, won’t you? You can’t do anything else, except die. My lord will treat you well if you serve him well.”

  “So let’s see what it’s like where we got to pass our lives,” van Rijn said.

  The party was heavily guarded, by young males—the sons, nephews, and retainers who comprised Moath’s fighting cadre—and robot blastguns that floated along on gravity platforms. Adzel’s size inspired caution, though he acted meek enough. Youngsters and idle servants trailed after. Females and workers goggled as the outworlders passed by. The Shenna race was not absolutely devoid of curiosity; no vertebrate is, on any known planet. They simply lacked the intensity of it that characterizes species like Homo or Dracocentaurus Sapiens. They were quite analogous in their love of novelty.

  “Castle” was a misleading word for the establishment. Once there had been an interlinked set of buildings, an enormous block, five or six kilometers on a side, a full tenth as high—yet for all that mass, graceful, many-colored, with columns of crystal that were nonfunctional but a joy to the eye, with towers that soared so far above the walls that their petal-shaped spires nearly vanished in heaven. It had been a place where millions lived and worked, a community which was an engineered unit, automated, nuclear-powered, integrated through traffic and communication with the whole planet.

  Now half of it was a ruin. Pillars were fallen, roofs gaped to the sky, machines had corroded away, creatures like birds nested in the turrets and creatures like rats scuttered through the apartments. Though destruction had pa
ssed the rest by, and the patient self-maintaining robots kept it in repair, the echoing hollowness of too many corridors, the plundered bareness of too many rooms and plazas and terraces, were more oppressive than the broken sections.

  Thea refused to say what had happened, centuries past. “Are you forbidden to tell us?” Adzel asked.

  She bit her lip. “No,” she said in a sad little voice, “not exactly. But I don’t want to.” After a moment: “You wouldn’t understand. You’d get the wrong idea. Later, when you know our lords the Shenna—”

  About half of the functional half of the complex was occupied today. The dwellers were not haunted by the past. They seemed to regard its overwhelming shell as part of their landscape. The ruins were quarried—that was one reason they were in poor condition—and the remainder would be taken over as population grew. A busy, lusty, brawling life surged between the walls and across the countryside. While robots did most of the essential work, Moath’s folk had plenty of tasks left to do, from technical supervision to their crude arts and crafts; from agriculture and forestry to prospecting and hunting; from education for one’s state in a hierarchical society to training for war. Aircraft bore passengers and cargo from other domains. Gravships shuttled between the planets of this system; hyperships trafficked with colonies newly planted among the nearer stars, or prowled further in exploration and imperialism. Even the peaceful routines of Dathyna had that thunderous vigor which is the Minotaur’s.

  Nonetheless, here was a life-impoverished world—metal-rich but life-impoverished. The crops grew thin in dusty fields. A perpetual faint stench hung in the air, blown from the nearby ocean, where the vast sea-plant blanket was dying and rotting faster than it replenished itself. The eastern hills were wooded, but with scrubby trees growing among the traces of fallen giants. At night, a hunter’s trumpet sounded from them lonelier than would have been the howl of the last wolf alive.
