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 fibratus 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 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 high 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.
