The Rise of Endymion

by Dan Simmons

  I lifted my wrist and spoke to the comlog, “Where the hell am I?”

  There was a hesitation and for a moment I thought the thing had been broken on Vitus-Gray-Balianus B. Then it spoke in the ship’s supercilious voice, “Unknown, M. Endymion. I have some data, but it is incomplete.”

  “Tell me.”

  There followed a rapid-fire listing of temperatures in Kelvin, atmospheric pressure in millibars, estimated mean density in grams per centimeter cubed, probable escape velocity in kilometers per second, and perceived magnetic field in gauss, followed by a long list of atmospheric gases and element ratios.

  “Escape velocity of fifty-four point two klicks per second,” I said. “That’s gas-giant territory, isn’t it?”

  “Most assuredly,” said the ship’s voice. “Jovian baseline is fifty-nine point five kilometers per second.”

  “But the atmosphere isn’t like a gas giant’s?” I could see the stratocumulus ahead of me building, like a nature holo run at accelerated speeds. The towering cloud must have reached ten klicks above me, its base disappearing in the purple depths below. Lightning flickered at its base. The sunlight on its far side seemed rich and low: evening light.

  “The atmosphere is unlike anything in my records,” said the comlog. “Carbon monoxide, ethane, acetylene, and other hydrocarbons violating Solmev equilibrium values can be easily explained by Jovian-style molecular kinetic energy and solar radiation breaking down methane, and the presence of carbon monoxide is a standard result of methane and water vapor mixing at deep layers where the temperature exceeds twelve hundred degrees Kelvin, but the oxygen and nitrogen levels …”

  “Yes?” I prompted.

  “Indicate life,” said the comlog.

  I turned completely around, inspecting the clouds and sky as if something were sneaking up on me. “Life on the surface?” I said.

  “Doubtful,” came the flat voice. “If this world follows Jovian-Whirl norms, the pressure at the so-called surface would be under seventy million Old Earth atmospheres with a temperature of some twenty-five thousand degrees Kelvin.”

  “How high are we?” I said.

  “Uncertain,” said the instrument, “but with the current atmospheric pressure of point seven six Old Earth standard, on a standard Jovian world I would estimate that we were above the troposphere and tropopause, actually in the lower reaches of the stratosphere.”

  “Wouldn’t it be colder that high? That’s almost outer space.”

  “Not on a gas giant,” said the comlog in its insufferable professorial voice. “The greenhouse effect creates a thermal inversion layer, heating layers of the stratosphere to almost human-optimum temperatures. Although the difference of a few thousand meters may show pronounced temperature increases or drops.”

  “A few thousand meters,” I said softly. “How much air is above and below us?”

  “Unknown,” said the comlog again, “but extrapolation would suggest that equatorial radius from the center of this world to its upper atmosphere would be approximately seventy thousand kilometers with this oxygen-nitrogen-carbon-dioxide layer extending for some three to eight thousand kilometers approximately two thirds of the distance from the planet’s hypothetical center.”

  “A three- to eight-thousand-klick layer,” I repeated stupidly. “Some fifty thousand klicks above the surface …”

  “Approximately,” said the comlog, “although it should be noted that at near-core pressures, molecular hydrogen becomes a metal …”

  “Yeah,” I said. “That’s enough for now.” I felt like I was going to be sick over the side of the kayak.

  “I should point out the anomaly that the interesting coloration in the nearby stratocumulus suggests the presence of ammonium monosulfide or polysulfides, although at apotropospheric altitudes, one would assume only the presence of ammonia cirrus clouds with true water clouds not forming until depths reach some ten standard atmospheres because of …”

  “Enough,” I said.

  “I only point this out because of the interesting atmospheric paradox involving …”

  “Shut up,” I said.

  IT GOT COLD AFTER THE SUN WENT DOWN. THE SUNSET itself I shall remember until I die.

  High, high above me, glimpses of what might be blue sky had darkened to a Hyperion-like deep lapis and then deepened further to dark purple. The clouds all around me grew brighter as the sky far above and the depths far below both grew darker. I say clouds, but the generic term is laughably unequal to conveying the power and grandeur of what I watched. I grew up in a nomadic-shepherd caravan on the treeless moors between Hyperion’s Great South Sea and the Pinion Plateau: I know clouds.

  Far above me, feathered cirrus and rippled cirrocumulus caught the twilight in a pastel riot of soft pinks, rose glows, violet tinges, and golden backlighting. It was as if I were in a temple with a high, rosy ceiling supported by thousands of irregular columns and pillars. The columns and pillars were towering mountains of cumulus and cumulonimbus, their anvil-shaped bases disappearing in the darkening depths hundreds or thousands of kilometers below my floating kayak, their rounded summits billowing high into the halo-tinged cirrostratus hundreds or thousands of kilometers above me. Each column of cloud caught the low, rich light passing through openings in the cloud many thousands of klicks to the west, and the light seemed to ignite the clouds as if their surfaces were made of wildly flammable material.

  “Monosulfide or polysulfides,” the comlog had said: well, whatever constituted these tawny cumulus in the diffuse daylight, sunset set them afire with rust-red light, brilliant crimson streaks, bloody tractus streaming away from the main cloud masses like crimson pennants, rose-colored fibranas weaving together the cirrus ceiling like muscle strands under the flesh of a living body, billowing masses of cumulus so white that they made me blink as if snowblinded, golden, striated cirroform spilling out from the boiling cumulonimbus towers like masses of blond hair blowing back from pale, upturned faces. The light deepened, richened, became so intense that it brought tears to my eyes, and then it became even more brilliant. Great, nearly horizontal shafts of Godlight burned between the columns, illuminating some here, casting others into shadow there, passing through ice clouds and bands of vertical rain on their way, spilling hundreds of simple rainbows and a thousand multiple rainbows. Then shadows moved up from the bruise-black depths, shading more and more of the still-writhing billows of cumulus and nimbus, finally climbing into the high cirrus and pond-rippled altocumulus, but at first the shadows brought not grayness or darkness, but an infinite palette of subtleties: gleaming gold dimming to bronze, pure white becoming cream and then dimming to sepia and shade, crimson with the boldness of spilled blood slowly darkening to the rust-red of dried blood, then fading to an autumnal tawny russet. The hull of my kayak lost its glint and the parasail above me quit catching the light as this vertical terminator moved past and above me. Slowly these shadows crept higher—it must have taken at least thirty minutes, although I was too absorbed in watching to check my comlog—and when they reached the cirrus ceiling, it was as if someone had dimmed all the lights in the temple.

  It was one hell of a sunset.

  I remember blinking then, overwhelmed by the interplay of light and cloud shadow and the oddly disturbing kinetic restlessness of all those broiling cloud masses, ready to rest my eyes while true darkness fell and to gather my thoughts. And that is when the lightning and aurora began playing.

  There had been no aurora borealis on Hyperion—or if there had been, I had never seen it. But I had seen an example of Old Earth’s northern lights on a peninsula that had once been the Scandinavian Republic while on my round-the-world dropship tour of that planet: they had been shimmering and gooseflesh-producing, rippling and dancing along the northern horizon like the filmy gown of a ghost dancer.

  This world’s aurora held none of that subtlety. Bands of light, solid striations of light—as discrete and discernible as the keys of a vertical piano—-began dancing hig
h in the sky in the direction I thought of as south. Other curtains of green, gold, red, and cobalt began shimmering against the dark world of air beneath me. These grew longer, broader, taller, stretching to meet and blend with other curtains of leaping electrons. It was as if the planet were cutting paper dolls out of shimmering light. Within minutes, every part of the sky was alive and dancing with vertical, slanted, and near-horizontal ribbons of banded color. The cloud towers became visible again, billows and pennants reflecting the strobe of thousands of these cold lights. I could almost hear the hiss and rasp of solar particles being driven along the terrifying lines of magnetic force banding this giant world.

  I could hear them: crashes, rumbles, snappings, loud pops, long chains of cracking sounds. I swiveled in my little cockpit and leaned over the hull to look straight down. The lightning and thunder had begun.

  I had seen enough lightning storms as a child on the moors. On Old Earth, Aenea, A. Bettik, and I regularly used to sit outside her shelter in the evening and watch the great electrical storms move over the mountains to the north. Nothing had prepared me for this.

  The depths, as I had called them, had been little more than a dark floor so far below me as to be laughable, a broiling promise of terrible pressures and more terrible heat. But now those depths were alive with light, leaping with lightning storms that moved from one visible horizon to the rest like a chain of nuclear bombs going off. I could imagine entire hemispheres of cities being destroyed in one of those rumbling chain reactions of light. I gripped the side of the kayak and reassured myself that the storms were hundreds of klicks below me.

  The lightning moved up the towers of cumulonimbus. Flashes of internal white light vied with the shimmers of colored light from the connecting auroras. The thunder-noise was subsonic, then sonic, subtly terrifying at first, then not subtle, but even more terrifying. The kayak and its parasail bucked and rocked in sudden downdrafts and elevator-quick lifts of thermals. I gripped the sides with mad strength and wished to God that I were on any other world but this.

  Then the lightning discharges began flashing from cloud tower to cloud tower.

  The comlog and my own reasoning had evaluated the scale of this place—an atmosphere tens of thousands of klicks deep, a horizon so far away that I could have dropped scores of Old Earths or Hyperions between me and the sunset—but the lightning bolts finally convinced me that this was a world made for giants and gods, not for humankind.

  The electrical discharges were wider than the Mississippi and longer than the Amazon. I had seen those rivers and I could see these bolts. I knew.

  I hunkered down in my little cockpit as if that would help me when one of these bolts caught my little flying kayak. The hairs on my forearms were standing straight up and I realized that the crawling sensation I felt on my neck and scalp was precisely that—the hair on my head was writhing like a nest of snakes. The comlog was flashing overload alarms on its diskey plate. It was probably shouting at me as well, but I could not have heard a laser cannon firing ten centimeters from my ear in that maelstrom. The parasail rippled and tore at the risers as heated air and imploding vacuums battered us. At one point, riding the wake of a bolt that blinded me, the kayak swung above horizontal, higher than the parasail. I was sure that the risers were going to collapse, the kayak and I were going to fall into the parasail shroud, and we would fall for minutes—hours—until pressure and heat ended my screaming.

  The kayak rocked back, then back again, then continued swinging like a maddened pendulum—but under the sail.

  In addition to the storm of lightning beneath me, in addition to the rising chain of explosions in every tower of cumulus, in addition to the searing bolts that now laced the towers like a web of firing neurons in a brain gone berserk, bundles of ball lightning and chain lightning suddenly began breaking loose from the clouds and floating in the dark spaces where my kayak flew.

  I watched one of these rippling, surging spheres of electricity drift not a hundred meters beneath me: it was the size of a small, round asteroid—an electric moonlet. The noise it made was beyond description, but memories surged unbidden of being caught in a forest fire in the Aquila fens, of the tornado that skipped over our caravan on the moors when I was five years old, of plasma grenades detonating against the great blue glacier on the Claw Iceshelf. No combination of these memories could match the energy violence tumbling along beneath the kayak like some runaway boulder made of blue and gold light.

  The storm lasted more than eight hours. Darkness lasted another eight. I survived the first. I slept through the last. When I awoke, shaken and thirsty, filled with dreams of light and noise, still partially deafened, badly needing to urinate and worried about falling out of the cockpit while I knelt to do so, I saw that morning light was painting the opposite side of the cloud pillars that had replaced the temple columns from the night before. Sunrise was simpler than sunset: the brilliant white and gold crawled down from the cirrus ceiling, along the roiling sides of the cumulus and nimbus, down to my layer where I sat shaking from the cold. My skin and clothes and hair were wet. Sometime during that night’s bedlam, it had rained on me and rained hard.

  I got to my knees on the padded floor of the hull, held tight to the cockpit rim with my left hand, made sure that the kayak’s swaying had steadied somewhat, and attended to business. The thin, gold stream glinted in morning light as it dropped into infinity. The depths were black, purple, and inscrutable once again. My lower back hurt and I remembered the kidney stone nightmare of the previous few days. That seemed like another life to me now, long ago and far away. Well, I thought, if there’s another tiny stone being passed, I’m not going to catch it today.

  I was buttoning up and settling back into the cockpit, trying to stretch my aching legs without actually falling out, thinking about the impossibility of finding another farcaster ring anywhere in this endless sky after that night of being blown off course—as if I had ever had a course—when I suddenly realized that I was not alone.

  Living things were rising from the depths and circling around me.

  • • •

  AT FIRST I SAW ONLY ONE CREATURE AND HAD NO scale with which to judge the size of the visitor. The thing could have been a few centimeters across and only meters from my floating kayak, or many kilometers across and far, far away. Then the organism swam between a distant cloud pillar and a more distant cumulus tower, and I realized that kilometers was a more reasonable guess of size. As it came closer, I saw the myriad of smaller forms accompanying it through the morning sky.

  Before I attempt to describe the things, I have to say that little in the history of humankind’s expansion in this arm of the galaxy had prepared us to describe large alien organisms. On the hundreds of worlds explored and colonized during and after the Hegira, most of the indigenous life discovered had been plants and a few very simple organisms, such as the radiant gossamers on Hyperion. The few large, evolved animal forms—the Lantern Mouths on Mare Infinitus, say, or the zeplins of Whirl—tended to be hunted to extinction. The more common result was a world filled with a few indigenous life-forms and a myriad of human-adapted species. Humanity had terraformed all these worlds, bringing its bacteria and earthworms and fish and birds and land animals in raw DNA form, defrosting embryos in the early seedships, building birthing factories in the later expansions. The result had been much as on Hyperion-vital indigenous plants such as the tesla trees and chauna and weirwood and some surviving local insects coexisting with thriving Old Earth transplants and biotailored adapts such as triaspen, everblues, oak trees, mallards, sharks, hummingbirds, and deer. We were not used to alien animals.

  And these were definitely alien animals rising to meet me.

  The largest one reminded me of the cuttlefish—again, one of Old Earth’s adapts—that thrived in the warm shallows of the Great South Sea on Hyperion. This creature was squidlike but almost transparent, its internal organs quite visible, although I admit that it was difficult to determine its ext
erior from its interior as it pulsed and throbbed and changed shape from second to second, almost like a starship morphing for battle. The thing had no head as such, not even a flattened, squidlike extension that might be considered a head, but I could make out a variety of tentacles, although fronds or filaments might be better words for the constantly swaying, retracting, extending, and quivering appendages. But these filaments were inside the pale, clear body as much as outside, and I was not sure if the creature’s movement through the clear air was a result of the swimming motion of the filaments or because of gases expelled as the giant cuttlefish expanded and contracted.

  As far as I could recall from old books and Grandam’s explanations, the zeplins on Whirl were much simpler in appearance—blimp-shaped gasbags, mere medusalike cells to hold their mix of hydrogen and methane, storing and metabolizing helium in their crude liftsacs, giant jellyfish floating in the hydrogen-ammonia-methane atmosphere of Whirl. As best I could remember, the zeplins ate a sort of atmospheric phytoplankton that floated in the noxious atmosphere like so much airborne manna. There were no predators on Whirl … until humans arrived in their floating bathyscaphes to harvest the rarer gases.

  As the cuttlefish creature grew closer, I saw the complexity of its innards: pale, pulsing outlines of organs and intestine-looking coils and what might be feeding filaments and tubes that might be for reproduction or elimination, and there were some appendages that might be sex organs, or perhaps eyes. And all the while it folded in on itself, retracted its curling filaments, then pulsed forward, tentacles extended fully, like a squid swimming through clear water. It was five or six hundred meters long.

  I began to notice the other things. Around the cuttlefish swarmed hundreds or thousands of golden, disc-shaped creatures, ranging in size from tiny ones perhaps as large as my hand to others larger than the heavy river mantas used to pull barges on Hyperion’s rivers. These things were also nearly transparent, although their insides were clouded by a sort of greenish glow that might have been an inert gas excited to luminescence by the animal’s own bio-electrical field. These things swarmed around the cuttlefish, at times appearing to be swallowed or absorbed by some orifice or another, only to reappear outside again. I could not swear that I saw the cuttlefish eating any of the swarming discs, but at one point I thought that I could see a cloud of the green-glowing things moving along the inside of the cuttlefish’s gut like ghostly platelets in a clear vein.
