“Never mind, Ship,” I said. The absence of pain made me almost giddy. “How long did it take you to finish the repairs?”

  “Five standard months,” said the ship. “Eight and one-half local months. This world has an odd lunar cycle with two highly irregular moons which I have postulated must be captured asteroids because of the …”

  “Five months,” I said. “And you’ve just been waiting the other three and a half years?”

  “Yes,” said the ship. “As instructed. I trust that all is well with A. Bettik and M. Aenea.”

  “I trust that too, Ship. But we’ll find out soon enough. Are you ready to leave this place?”

  “All ship’s systems are functional, M. Endymion. Awaiting your command.”

  “Command is given,” I said. “Let’s go.”

  The ship piped in the holo showing us rising above the river. It was dark out, but the night-vision lenses showed the swollen river and the farcaster arch only a few hundred meters upstream. I had not seen it in the fog. We rose above the river, above the swirling clouds.

  “River’s up from the last time I was here,” I said.

  “Yes,” said the ship. The curve of the planet became visible, the sun rising again above fleecy clouds. “It floods for a period of some three standard months every local orbital cycle, which equals approximately eleven standard months.”

  “So you know what world this is now?” I said. “You weren’t sure when we left you.”

  “I am quite confident that this planet was not among the two thousand eight hundred sixty-seven worlds in the General Catalogue Index,” said the ship. “My astronomical observations have shown that it is neither in Pax space nor in the realm of the former WorldWeb or Outback.”

  “Not in the old WorldWeb or Outback,” I repeated. “Where is it then?”

  “Approximately two hundred and eighty light-years galactic northwest of the Outback system known as NNGC 4645 Delta,” said the ship.

  Feeling slightly groggy from the painkiller, I said, “A new world. Beyond the Outback. Why did it have farcasters then? Why was the river part of the Tethys?”

  “I do not know, M. Endymion. But I should mention that there is a multitude of interesting life-forms which I observed by remotes while resting on the river bottom. Besides the river manta-ish creature which you and M. Aenea and A. Bettik observed downriver, there are more than three hundred observed species of avian variety and at least two species of humanoids.”

  “Two species of humanoids? You mean humans.”

  “Negative,” said the ship. “Humanoids. Definitely not Old Earth human. One variety is quite small—little more than a meter in height—with bilateral symmetry but quite variant skeletal structure and a definite reddish hue.”

  A memory flitted by of a red-rock monolith Aenea and I had scouted on the lost hawking mat during our short stay here. Tiny steps carved in the smooth stone. I shook my head to clear it. “That’s interesting, Ship. But let’s set our destination.” The curve of the world had become pronounced and stars were gleaming unblinkingly. The ship continued to rise. We passed a potato-shaped moon and moved farther from orbit. The unnamed world became a blinding sphere of sunlit clouds. “Do you know the world known as T’ien Shan, or the ‘Mountains of Heaven’?”

  “T’ien Shan,” repeated the ship. “Yes. As far as my memory serves, I have never been there, but I have the coordinates. A small world in the Outback, settled by refugees of the Third Chinese Civil War late in the Hegira.”

  “You won’t have any trouble getting there?”

  “None would be anticipated,” said the ship. “A simple Hawking-drive jump. Although I recommend that you use the autosurgeon as your cryogenic fugue cubby during the jump.”

  I shook my head again. “I’ll stay awake, Ship. At least after the doc heals my leg.”

  “I would recommend against that, M. Endymion.”

  I frowned. “Why? Aenea and I stayed awake during the other jumps.”

  “Yes, but those were relatively short voyages within the old WorldWeb,” said the ship. “What you now call Pax space. This will be a bit more extensive.”

  “How extensive?” I said. My naked body felt a sudden chill. Our longest jump—to Renaissance Vector System—had taken ten days of ship travel time and five months of time-debt for the Pax Fleet waiting for us. “How extensive a trip?” I said again.

  “Three standard months, eighteen days, six hours, and some minutes,” said the ship.

  “That’s not too bad a time-debt,” I said. I last saw Aenea just after her sixteenth birthday. She would gain a few months on me. Her hair might be longer. “We had a greater time-debt jumping to Renaissance System.”

  “That is not time-debt, M. Endymion,” said the ship. “That is shiptime.”

  This time the chill along the length of my body was real. My tongue seemed thick. “Three months’ shiptime … how much time-debt?”

  “For someone waiting on T’ien Shan?” said the ship. The jungle world was a speck behind us now as we accelerated toward a translation point. “Five years, two months, and one day,” said the ship. “As you are aware, the time-debt algorithm is not a linear function of C-plus duration, but includes such factors as …”

  “Ah, Jesus,” I said, raising my wrist to my clammy forehead in the autosurgeon coffin. “Ah, damn.”

  “Are you in pain, M. Endymion? The dolorometer suggests you are not, but your pulse has become erratic. We can increase the level of painkiller …”

  “No!” I snapped. “No, it’s all right. I just … five years … damn.”

  Did Aenea know this? Had she known that our separation would cover years of her life? Perhaps I should have brought the ship through the downriver farcaster. No, Aenea had said to fetch the ship and fly it to T’ien Shan. The farcaster had brought us to Mare Infinitus last time. Who knows where it would have taken me this time.

  “Five years,” I muttered. “Ah, damn. She’ll be … damn, Ship … she’ll be twenty-one years old. A grown woman. I’ll have missed … I won’t see … she won’t remember …”

  “Are you sure you are not in pain, M. Endymion? Your vital signs are turbulent.”

  “Ignore that, Ship.”

  “Shall I prepare the autosurgeon for cryogenic fugue?”

  “Soon enough, Ship. Tell it to put me under while it heals my leg tonight and deals with the fever. I want at least ten hours’ sleep. How long until translation point?”

  “Only seventeen hours. It is well inside this system.”

  “Good,” I said. “Wake me in ten hours. Have a full breakfast ready. What I used to have when we celebrated ‘Sunday’ on our voyage out.”

  “Very good. Anything else?”

  “Yeah, do you have any record holos of … of Aenea … on our last trip?”

  “I have stored several hours of such records, M. Endymion. The time you were swimming in the zero-g bubble on the outer balcony. The discussion you had about religion versus rationality. The flying lessons down the central dropshaft when …”

  “Good,” I said. “Cue those up. I’ll look through them over breakfast.”

  “I will prepare the autosurgeon for three months of cryogenic sleep after your seven-hour interlude tomorrow,” said the ship.

  “I took a breath. “All right.”

  “The surgeon wishes to commence repairing nerve damage and injecting antibiotics now, M. Endymion. Do you wish to sleep?”

  “Yes.”

  “With dreams or without? The medication may be tailored for either neurological state.”

  “No dreams,” I said. “No dreams now. There’ll be time enough for those later.”

  “Very good, M. Endymion. Sleep well.”

  Part Two

  15

  am on the Phari marketplace shelf with A. Bettik, Jigme Norbu, and George Tsarong when I hear the news that Pax ships and troops have finally come to T’ien Shan, the “Mountains of Heaven.”

  “We should tell Aen
ea,” I say. Around us, above us, and under us, thousands of tons of scaffolding rock and creak with the weight of crowded humanity buying, selling, trading, arguing, and laughing. Very few have heard the news of the Pax’s arrival. Very few will understand the implications when they do hear it. The word comes from a monk named Chim Din who has just returned from the capital of Potala, where he works as a teacher in the Dalai Lama’s Winter Palace. Luckily, Chim Din also works alternate weeks as a bamboo rigger at Hsuan-k’ung Ssu, the “Temple Hanging in Air,” Aenea’s project, and he hails us in Phari Marketplace as he is on his way to the Temple. Thus we are among the first people outside the court at Potala to hear of the Pax arrival.

  “Five ships,” Chim Din had said. “Several score of Christian people. About half of them warriors in red and black. About half of the remaining half are missionaries, all in black. They have rented the old Red Hat Sect gompa near Rhan Tso, the Otter Lake, near the Phallus of Shiva. They have sanctified part of the gompa as a chapel to their triune God. The Dalai Lama will not allow them to use their flying machines or go beyond the south ridge of the Middle Kingdom, but he has allowed them free travel within this region.”

  “We should tell Aenea,” I say again to A. Bettik, leaning close so that I can be heard over the marketplace babble.

  “We should tell everyone at Jo-kung,” says the android. He turns and tells George and Jigme to complete the shopping—not to forget arranging porters to carry the orders of cable and extra bonsai bamboo for the construction—and then he hoists his massive rucksack, tightens his climbing hardware on his harness, and nods to me.

  I heft my own heavy pack and lead the way out of the marketplace and down the scaffolding ladders to the cable level. “I think the High Way will be faster than the Walk Way, don’t you?”

  The blue man nods. I had hesitated at suggesting the High Way for the return trip, since it has to be difficult for A. Bettik to handle the cables and slideways with just one hand. Upon our reunion, I had been surprised that he had not fashioned a metal hook for himself—his left arm still ends in a smooth stump halfway between his wrist and elbow—but I soon saw how he used a leather band and various leather attachments to make up for his missing digits. “Yes, M. Endymion,” he says. “The High Way. It is much faster. I agree. Unless you want to use one of the flyers as courier.”

  I look at him, assuming that he is kidding. The flyers are a breed apart and insane. They launch their paragliders from the high structures, catching ridge lift from the great rock walls, crossing the wide spaces between the ridges and peaks where there are no cables or bridges, watching the birds, looking for thermals as if their lives depended on it … because their lives do depend on it. There are no flat areas on which a flyer can set down if the treacherous winds shift, or if their lift fails, or if their hang gliders develop a problem. A forced landing on a ridge wall almost always means death. Descent to the clouds below always means death. The slightest miscalculation in gauging the winds, the updrafts, the downdrafts, the jet stream … any mistake means death for a flyer. That is why they live alone, worship in a secret cult, and charge a fortune to do the Dalai Lama’s bidding by delivering messages from the capital at Potala, or to fly prayer streamers during a Buddhist celebration, or to carry urgent notes from a trader to his home office to beat competitors, or—so the legend goes—to visit the eastern peak of T’ai Shan, separated for months each local year from the rest of T’ien Shan by more than a hundred klicks of air and deadly cloud.

  “I don’t think we want to entrust this news to a flyer,” I say.

  A. Bettik nods. “Yes, M. Endymion, but the paragliders can be purchased here at the marketplace. At the Flyer’s Guild stall. We could buy two and take the shortest route back. They are very expensive, but we could sell some of the pack zygoats.”

  I never know when my android friend is joking. I remember the last time I was under a parasail canopy and have to resist the urge to shiver. “Have you ever paraglided on this world?” I say.

  “No, M. Endymion.”

  “On any world?”

  “No, M. Endymion.”

  “What would you think our chances would be if we tried?” I say.

  “One in ten,” he says without a second’s hesitation.

  “And what are our chances on the cables and slideway this late in the day?” I say.

  “About nine in ten before dark,” he says. “Less if sunset catches us short of the slideway.”

  “Let’s take the cables and slideway,” I say.

  WE WAIT IN THE SHORT QUEUE OF MARKET-GOERS leaving by cable, and then it is our turn to walk onto the step-off platform. The bamboo shelf is about twenty meters beneath the lowest marketplace scaffolding and it extends about five meters farther out over the abyss than does the rest of Phari. Beneath us there is nothing but air for thousands of meters and at the bottom of that emptiness only the ubiquitous sea of clouds that rolls against the ridges of upthrust rock like a white tide spilling against stone pilings. More kilometers beneath those clouds, I know, are poisonous gases and the surging, acidic sea that covers all of this world except its mountains.

  The cablemaster gestures us forward and A. Bettik and I step onto the jump platform together. From this nexus, a score or more of cables slant out and down across the abyss, creating a black spiderweb that disappears at the edge of vision. The nearest cable terminus is more than a kilometer and a half to the north—on a little rock fang that stands out against the white glory of Chorno Lori, “Queen of Snow”—but we are going east across the great gap between the ridges, our terminal point is more than twenty kilometers away, and the cable dropping away in that direction appears to end in midair as it blends into the evening glow of the distant rock wall. And our final destination is more than thirty-five klicks beyond that to the north and east. Walking, it would take us about six hours to make the long trip north along Phari Ridge and then east across the system of bridges and catwalks. Traveling by cable and slideway should take less than half that time, but it is late in the day and the slideway is especially dangerous. I glance at the low sun again and wonder again about the wisdom of this plan.

  “Ready,” growls the cablemaster, a brown little man in a stained patchwork chuba. He is chewing besil root and turns to spit over the edge as we step up to the clip-on line.

  “Ready,” A. Bettik and I say in unison.

  “Keep ’ur distance,” growls the cablemaster and gestures for me to go first.

  I shake my traveling risers loose from my full-body harness, slide my hands over the crowded gear sling that we call a rack, find the two-bearing pulley by feel, clip it on to the riser ring with a carabiner, run a Munter hitch into a second carabiner as a friction-brake backup to the pulley brake, find my best offset-D carabiner and use it to clip the pulley flanges together around the cable, and then run my safety line through the first two carabiners while tying a short prusik sling onto the rope, finally clipping that on to my chest harness below the risers. All of this takes less than a minute. I raise both hands, grab the D-ring controls to the pulley, and jump up and down, testing both the pulley connection and my clip-ons. Everything holds.

  The cablemaster leans over to inspect the double-D-ring attachment and the pulley clamp with expert eyes. He runs the pulley up and back a meter, making sure that the near-frictionless bearings are sliding smoothly in their compact housing. Finally he puts all of his weight on my shoulders and harness, hanging on me like a second rucksack, and then releases me to make sure that the rings and brakelines hold. I am sure that he cares nothing if I fall to my death, but if the pulley was to stick somewhere on the twenty klicks of braided monofilament cable running out there to invisibility, it will be this cablemaster who will have to clear the mess, hanging from his etriers or belay seat over kilometers of air while waiting commuters seethe. He seems satisfied with the equipment.

  “Go,” he says and slaps me on the shoulder.

  I jump into space, shifting my bulging rucksack high
on my back as I do so. The harness webbing stretches, the cable sags, the pulley bearings hum ever so slightly, and I begin to slide faster as I release the brake with both thumbs on the D-ring controls. Within seconds I am hurtling down the cable. I lift my legs and sit back up into the harness seat in the way that has become second nature to me in the past three months. K’un Lun Ridge, our destination, glows brightly as sunset shadow begins to fill the abyss beneath me and evening shade moves down the wall of Phari Ridge behind me.

  I feel a slight change in the cable tension and hear the cable humming as A. Bettik begins his descent behind me. Glancing back, I can see him leaving the jump-off platform, his legs straight ahead of him in the approved form, his body bobbing beneath the elastic risers. I can just make out the tether connecting the leather band on his left arm to the pulley brakeline. A. Bettik waves and I wave back, swiveling in my harness to pay attention to the cable screaming past me as I continue hurtling out over the gorge. Sometimes birds land on the cable to rest. Sometimes there is a sudden ice buildup or braid spurs. Very rarely there is a snagged pulley of someone who has met with an accident or cut away from their harness for reasons known only to themselves. Even more rarely, but enough to fix it in the mind, someone with a grudge or vague psychopathic tendencies will pause on the cable to loop a chock sling or spring-loaded cam around it, leaving a little surprise for the next person to come flying along the line. The penalty for that crime is death by flinging from the highest platform of Potala or Jo-kung, but this is of little solace to the person who first encounters the chock or cam.

  None of these eventualities materialize as I slide across the emptiness under the ultralight cable. The only sound is the slight hum from the pulley brake as I moderate my speed and the soft rush of air. We are still in sunlight and it is late spring on this world, but the air is always chilly above eight thousand meters. Breathing is no problem. Every day since I arrived on T’ien Shan, I thank the gods of planetary evolution that even with the slightly lighter gravity here—0.954 standard—the oxygen is richer at this altitude. Glancing down at the clouds some klicks below my boots, I think of the seething ocean in that blind pressure, stirred by winds of phosgene and thick C02. There is no real surface land on T’ien Shan, merely that thick soup of a planetary ocean and the countless sharp peaks and ridges rising thousands of meters to the O2 layer and the bright, Hyperion-like sunlight.
