A Stone in Heaven df-12

by Poul Anderson

  When it becomes freshly abundant, as around an active volcano, these organisms multiply until sheer numbers make them visible, a yellow smoke in air, a hue in water. Dying, they enrich the soil. This is the Golden Tide whose coming has brought fertility to land after land, whose dwindling has brought famine till populations died sufficiently back. The natives also transport sulfur, on a far smaller scale; their trade in it has conditioned their histories more than the salt trade has those of humans.

  Given the oxygen concentration and the incidence of lightning, fires kindle easily and burn fiercely. Outside of wetlands, such a thing as a climax forest scarcely exists; woods burn down too often. Vegetation has made various adaptations to this, deep roots or bulbs, rapid reseeding, and the like. Most striking is that of the huge, diverse botanical family which we call pyrasphale. It synthesizes a silicon compound which makes it incombustible.

  The pyrasphales have numerous analogies to the grasses of Terra or the yerbs of Hermes. They are comparative latecomers, that have taken over the larger part of most lands and proliferated into a bewildering variety of forms. Many do bear a superficial resemblance to this or that grass. Their appearance was doubtless responsible for a period of massive extinction about fifty million years ago; they crowded out older plants, and countless animals could not digest their fireproofing. Later herbivores have adjusted, either excreting it unchanged or breaking it down with the help of symbiotic microbes.

  Pyrasphale has not displaced everything else. Where it reigns alone, that is apt to be by default. Ordinarily, a landscape covered by it has stands of trees, shrubs, thorn, or cane as well.

  The animals of Ramnu exhibit their own abundant analogies to those of Terra, including two sexes, vertebrates and invertebrates, exothermic and endothermic metabolisms. The typical vertebrate has a head in front, with jaws, nose, two eyes, two ears; it bears four true limbs; commonly it sports a tail. But the differences exceed the likenesses.

  Among the most obvious is the general smallness, under that gravity. Outside the seas, the very biggest creatures mass a couple of tonnes; and they inhabit regions of lake and swamp, where the water supports most of their weight as they browse around. A plain may teem with herds of assorted species, but nearly every one is dog-sized or less. An occasional horse-tall beast may loom majestic above them. It has a special feature, of which more later. Otherwise, at first it strikes a human odd to see a graviportal build on an animal no bigger than a collie. The gracile forms are tiny.

  The long, cold nights set a premium on endothermy. Exotherms must find a place to sleep where they won’t freeze (or, they hope, be dug up and eaten) or else start a new generation by sunset whose juvenile stage can survive. Plants have developed their own solutions to the same problem, including a family which secretes antifreeze and several families which make freezing a part of their life cycles.

  An intermediate sort of animal has a high metabolism to keep warm at night but—outside the polar regions and highlands—must take shelter by day, lest it get too warm. Complete endothermy is harder to achieve than on Terra, since water evaporates reluctantly. The larger animals grow cooling surfaces such as big ears or dorsal fins. Flyers face less difficulty in this regard, for their wings provide those surfaces; but it is worth noting that none have feathers. They are abundant on Ramnu, where the gravity is more or less offset by the thickness of the atmosphere. The swift drop of pressure with altitude does make most of them stay close to the ground. A few scavengers can soar high. Then there are the gliders; but of these, too, more later.

  Among the land Vertebrates, an order of viviparous endotherms exists which has no Terran parallel: the pleurochladoi. Between the fore- and hindlimbs, a pair of ribs has become the foundation, anchored to an elaborate scapular process, of two false limbs, which humans call extensors. It is thought that these lengths of muscle originated in a primitive, short-legged creature which thus found a way to hitch itself along a trifle faster. The development was so successful that descendants radiated into hundreds of kinds.

  Extensors give added support; grasping, hauling, pushing, they give added locomotion. Hence they have enabled certain of their possessors to become as big as mustangs.

  In quite a different direction, extensors produced the sub-order of gliding animals. These grew membranes from the forequarters to the tips of the extensors, and from the tips to the hindquarters. The membranes doubtless began as a cooling device, which they remain, but they have elaborated into airfoils—vanes. Such a beast can fold them and run around freely. Or it can stiffen the extensors, thereby spreading the vanes, and glide down from a height. Given favorable currents, it can go astonishingly far in the dense air, or perform extraordinary maneuvers. Thereby it gets fruit, prey, escape from enemies, easy transportation.

  Most gliders are bat-sized, but a few have become larger, and a few of these have become bipedal. Among them are the sophonts.

  Red-gold, Niku waxed bright among the stars. In less than a day, it would be the sun.

  Flandry saw how Banner’s glance kept straying to its image in the screen. This was to have been a happy evenwatch, the last peaceful span they would know for a time they did not know—perhaps an eternity. Garbed in the finest they had along, they sipped their drinks in between dances until Chives set forth the best dinner he was capable of. Afterward Flandry had him join them in a valedictory glass, but the batman said goodnight as soon as that was done. Now—

  Cognac was mellow on the tongue, fragrant in the nostrils, ardent along the throat and in the blood. Flandry didn’t smoke while he savored stuff as lordly as this. He did make it an obbligato to the sight and nearness of Banner. They were side by side; when she looked ahead, into the stars, he saw the proud profile. Tonight a silver circlet harnessed the tide of her mane. The hair flowed lustrous brown, touched by minute, endearing streaks of white. A bracelet Yewwl had given her, raw gemstones set in bronze, would have been barbarically massive on her left wrist, save that the casting was exquisite. She wore a deep-blue velvyl gown, long, low-cut, and though her bosom was small, the curve of it up toward her throat made him remember Botticelli.

  He was not in love with her, nor—he supposed—she with him, except to the gentle degree that was only natural and that, in ordinary life, would only have added piquancy to friendship. He did find her attractive, and thought the cosmos of her as a person, in her own right, not merely because she was daughter to Max Abrams. So much had he come to respect her on this voyage that he no longer felt guilty about having brought her.

  Soft in the background, music played as it had done for forty generations before theirs, the New World Symphony.

  Abruptly she turned face and body about, toward him. The green eyes widened. “Dominic,” she asked, “why are you here?”

  “Huh?” he responded inelegantly. Don’t let her get too serious. Help her stay happy. “Well, that depends on your exact meaning of the word ‘why.’ In an empirical sense, I am here because sixty-odd years ago, an operatic diva had an affair with a space captain. In the higher or philosophical sense—”

  She interrupted by laying a hand over his. “Please don’t clown. I want to understand.” She sighed. “Though maybe you won’t want to tell me. Then I won’t insist; but I hope you will.”

  He surrendered. “What is it you’d like to know?”

  “Why you are here—bound for Ramnu instead of Hermes.” Quickly: “I know you had to investigate what Cairncross is hiding. If he really does plan a coup—”

  Yes, I do believe that’s his aim. What else? As Grand Duke, he’s gone as far as he can, and he’s known to be a man of vaulting ambition. He’s popular among his people, and they are resentful of the Imperium; it’d be no trick to quietly collect personnel for the illicit preparation of war materiel, and he controls plenty of places where the work can go on in secret—Babur, Ramnu—When he’s ready, when he announces his intention, men will flock to his standard. It won’t take any enormous striking force if the operation is wel
l organized. He can exploit surprise, punch through, kill Gerhart, and proclaim himself Emperor. When Terra lies hostage to his missiles, he won’t be directly attacked.

  Fighting will occur elsewhere, no doubt, but it will be between those who’ll want to accept him and those who’ll not. Many will. Gerhart is not beloved. Cairncross can set forth the claim that he is righting grievous wrongs and intends to right others; that in this dangerous era, the Empire needs the leader of greatest, proven ability; even that he has a dash of Argolid in his ancestry. A lot of Navy officers will feel they should go along with him simply to end the strife before it ruins too much, and because he is now the alternative to a throne back up for grabs. Others, as his cause gathers momentum, will deem it prudent to join. Yes, Edwin has a good chance of pulling it off, amply good for a warrior born.

  “—though things you’ve said about the Emperor do make me wonder if you care what happens to him,” Banner stumbled onward.

  Flandry scowled. “I don’t, per se. However, he isn’t intolerably bad; in fact, he shows reasonable intelligence and restraint. Besides, well, he is a son of Hans, and I rather liked that old bastard. But mainly, we can’t afford a new civil war, and anybody who’d start one is a monster.”

  Her fingers tightened across his. “You talked about buying years for people to live in.”

  He nodded. “I’m no sentimentalist, but I’ve witnessed wars. I don’t relish the idea of sentient beings with their skins burnt off and their eyeballs melted, but not yet able to die.” He stopped. “Sorry. That’s not nice dinner table conversation.”

  She gave him a faint smile. “No, but I’m not a perfectly nice person myself. All right, agreed, this has to be prevented. Before it’s too late, you have to find out if a coup is in the works, and in that case get proof that’ll make the Navy act. You think probably there’s evidence in the Nikuan System. But why are you going to collect it yourself? Wouldn’t it be wiser to proceed to Hermes and potter around, being harmless? Meanwhile I could accompany men of yours to Ramnu and they’d do the job.”

  Flandry shook his head. “I considered that, obviously,” he replied; “but I’ve told you before, I’m afraid Cairncross is almost ready to strike. I dare not be leisurely.”

  “Still, you could have covered your ass, couldn’t you?”

  He blinked, then laughed. “Perhaps. Though on Hermes I’d be at Cairncross’ mercy, you realize.”

  “But you could have made an excuse to stay home, and dispatched a crew in secret,” she persisted. “Feigned illness or whatnot. You’re too clever for anybody to make you go where you don’t want to.”

  “You’re trying to flatter me,” he said. “You’re succeeding. As a matter of fact, with my usual humility I admit that you’ve pointed to the real reason. I’ve trained several excellent people, but none are quite as clever as me. None would have quite the probability of success that I do.” He preened his mustache. “Also, to be honest, I confess I was getting bored. I was much overdue for raising a bit of hell.”

  Still her eyes would not release him. “Is that the whole truth, Dominic?”

  He shrugged. “In a well-known phrase from an earlier empire, what is truth?”

  Her tone shivered. “I think your underlying reason is this. The mission is dangerous. Failure means a terrible punishment for whoever went and got caught afterward. The fact that he went under your orders wouldn’t save him from the wrath of a Grand Duke whose ‘insulted honor’ the Imperium would find it politic to avenge.” She drew breath. “Dominic, you served under my father, and he was an officer of the old school. An officer does not send men to do anything he would not do himself. Isn’t that it, dear?”

  “Oh, I suppose a bit of it is,” he grumbled.

  Her glance dropped. How long the lashes lay, above those finely carven cheekbones. He saw the blood rise in face and bosom. “I felt sure, but I wanted to hear it from you,” she whispered. “We’ve got plenty of noble titles around these days, but damn few noble spirits.”

  “Oh, hai, hai,” he protested. “You know better. I lie, I steal, I cheat, I kill, I fornicate and commit adultery, I use shocking language, I covet, and once I had occasion to make a graven image. Now can we relax and enjoy our evening?”

  She raised her countenance to his. Her smile brightened. “Oh, yes,” she said. “Why, in your company I’d expect to enjoy exile.”

  They had talked about that, what to do if the mission failed but they survived. A court martial would find him guilty of worse than insubordination; defiance of a direct Imperial command was treason. She was an accomplice. The maximum penalty was death, but Flandry feared they would get the “lighter” sentence of life enslavement. He didn’t propose to risk that. He’d steer for a remote planet where he could assume a new identity, unless he decided to seek asylum in the Domain of Ythri or collect a shipful of kindred souls and fare off into the altogether unknown.

  Banner had agreed, in pain. She had far more to lose than he did, a mother, a brother and sister and their families, Yewwl and her lifework.

  Has she found hope, now, beyond the wreckage of hope? His heart sprang for joy.

  She leaned close. Her blush had faded to a glow, her look and voice were steady. “Dominic, dear,” she said, “ever since that hour in the gym, you’ve been the perfect knight. It isn’t necessary any longer.”

  Ramnu swelled steadily in the forward screen, until it owned the sky and its dayside radiance drowned stars out of vision. The colors were mostly white upon azure, like Terra’s, though a golden tinge lay across them in this weaker, mellower sunlight. Cloud patterns were not the same, but wider spread and more in the form of bands, spots, and sheets than of swirls; surface features were hidden from space, save as vague shadowiness here and there. The night side glimmered ghostly under moonlight and starlight. Brief, tiny fire-streaks near the terminator betokened monstrous lightning strokes. Brought into being by a magnetic field less than Jovian but stronger than Terran, auroras shook their flags for an incoming man to see above polar darkness.

  Flandry sat at the pilot console. Hooligan continued doing the basic navigation and steering herself, but he wanted his hand and judgment upon her, that he might arrive in secret. Besides, he meant to use the instruments in the control section to study the moons and any possible traffic in the system.

  He passed close enough by Diris, the innermost, that he could make out Port Lulang, the scientific base. It was a huddle of domes, hemicylinders, masts, dishes, beside a spacefield, in the middle of a large, symmetrical formation oddly like Sullivan’s Hoofprint on Io; little that was Cynthian remained except the name. Otherwise the satellite was nearly featureless. Once it had exceeded his mother world in size; but the supernova whiffed away everything above its metallic core. Probably naught whatsoever would have survived, had not the shrunken bulk of Ramnu given some shielding. As the melted ball cooled to solidity, no asteroids ormeteoroids smote to crater it. Those had been turned into gas, and dissipated with the rest of the nebula among the stars.

  Tiglaia showed a measure of ruggedness; it had kept the mass to generate orogenic forces. Elaveli, outermost and largest, bore mountains, sharp-edged as when first they were uplifted.

  Flandry probed toward the latter, but got no sight of Port Asmundsen, the industrial base there. He wasn’t observing from the proper angle, and dared not accelerate into a different course lest he be noticed. If his idea about Cairncross was right, these days the expanded facilities included war-craft. Anyway, Banner had confirmed that nothing unusual was apparent from outside. Whatever evil was hatching did so under camouflage or in man-made caverns. Neutrino detectors spoke of substantial nuclear powerplants. Yes, they impress me as being rather more than required by mining operations. Having an exposed planetary core makes the enterprise worthwhile for Hermes—but scarcely this profitable, when the same metals are available closer to home.

  As for Dukeston—His look strayed back to Ramnu. The commercial base on the
planet had likewise been a minor thing, until lately. A sulfur-rich marshland produced certain biologicals, notably a finegrained hardwood and the antibiotic oricin, effective against the Hermetian disease cuprodermy. They were barely cheaper to obtain here and to ship back than to synthesize. They might not have been were not the nearby Chromatic Hills a well-endowed source of palladium and other minerals.

  Why had Dukeston, too, seen considerable recent growth? And why had it, too, become hard to enter and to deal with? True, it and Wainwright Station were separated by five thousand kilometers of continent. A parameter in choosing the site for it had been the desire that its cultural influence reach only the natives in its vicinity, not those whom the xenologists made their principal subjects of study. Nevertheless, people used to flit freely back and forth, often just to visit. General Enterprises used to be generous in supplying the Ramnu Research Foundation with help, equipment, materials.

  But under the present director, Nigel Broderick—Well, he explained the niggardliness and the infrequency of contact by declaring that the expansion itself, under adverse conditions, took virtually all the resources at his beck. The undertaking was a part of great Duke Edwin’s far-sighted plan for restoring the glory and prosperity of Hermes. His Grace had ordered stringent security measures against the possibility of sabotage, in these uneasy times. No exceptions could be made, since a naive scientist might innocently pass information to the wrong persons. If this attitude seemed exaggerated, that was because you did not know the ramifications of the whole situation. His Grace alone did that, and ours was not to question him.
