He hesitated. "Well, I think so. How should I know? And between the Crust and the Quantum Sea is the Mantle - the Air we breathe - about six hundred meters deep." He looked into her face, a disconcerting mixture of suspicion and pity evident there. "That's the shape of the Star. The world. Any kid in Parz City could have told you all that."

She shrugged. "Or any Human Being. Maybe there was no difference once."

She wished Adda were awake, so she could learn more of the secret history of her people. She turned her face to the window.

In the last hours of the journey the inverted Crust landscape changed again.

Dura, with Farr now awake and at her side, stared up, fascinated, watching the slow evolution of the racing Crustscape. There was very little left of the native forest here, although a few trees still straggled from small copses. The clean, orderly regularity of the fields they'd pa.s.sed under to the North - further upflux, upflux, as she was learning to call it - was breaking up into a jumble of forms and textures. as she was learning to call it - was breaking up into a jumble of forms and textures.

Farr pointed excitedly, his eyes round. Dura followed his gaze.

They weren't alone in the sky, she realized: in the far, misted distance something moved - not a car; it was long, dark, like a blackened vortex line. And like Mixxax's car it was heading for the Pole, threading along the Magfield.

She said, "That must be thousands of mansheights long."

Toba glanced dismissively. "Lumber convoy," he said. "Coming in from upflux. Nothing special. d.a.m.n slow, actually, if you get stuck behind one."

Soon there were many more cars in the Air. Mixxax, grumbling, often had to slow as they joined streams of traffic sliding smoothly along the Magfield flux lines. The cars came in all shapes and sizes, from small one-person buggies to grand chariots drawn by teams of a dozen or more pigs. These huge cars, covered in ornate carvings, quite dwarfed poor Mixxax's; Toba's car, thought Dura, which had seemed so grand and terrifying out in the forest upflux, now appeared small, shabby and insignificant.

Much, she was coming to realize, like its owner.

The colors of the Crust fields were changing: deepening and becoming more vivid. Farr asked Mixxax, "Different types of wheat?"

Mixxax showed little interest in these rich regions from which he was excluded. "Maybe. Flowers, too."

"Flowers?"

"Plants bred for their beauty - their shape, or color; or the scent of the photons they give off." He smiled. "Actually, Ito grows some blooms which..."

"Who's Ito?"

"My wife. Nothing as grand as this, of course; after all, we're flying over the estates of Hork's court now."

Farr had his face pressed to a window of the car. "You mean people grow plants just for the way they look?"

"Yes."

"But how do they live? Don't they have to hunt for food, as we do?"

Dura shook her head. "Folk here don't hunt, Farr. I've learned that much. They grow special kinds of gra.s.ses, and eat them."

Mixxax laughed bitterly. " 'Folk here,' as you call them, don't even do that, I I do that, in my scrubby farm on the edge of the upflux desert. I grow food to feed the rich folk in Parz... and I pay them taxes so they can afford to buy it. And that," he finished bitterly, "is how Hork's courtiers have enough leisure time to grow flowers." do that, in my scrubby farm on the edge of the upflux desert. I grow food to feed the rich folk in Parz... and I pay them taxes so they can afford to buy it. And that," he finished bitterly, "is how Hork's courtiers have enough leisure time to grow flowers."

The logic of that puzzled Dura, but - understanding little - she let it pa.s.s.

Now, suddenly, the queue of cars in front of them cleared aside, and the view ahead was revealed.

Dura heard herself gasp.

Farr cried out, sounding like a small child. "What is it?"

Mixxax turned and grinned at him, evidently enjoying his moment of advantage. "That," he said, "is Parz City. We have arrived."

6.

MUUB ARRIVED AT THE RECEPTION Gallery shortly before the start of the Grand Tribute. He moved to the front of the Gallery, so that he could see down the full depth of Pall Mall, and selected a body-coc.o.o.n close to Vice-Chair Hork's customary place. A servant drifted around him for a few moments, adjusting the coc.o.o.n so it fit snugly, and offered him drinks and other refreshments. Muub, unable to shake off weariness, found the harmless little man as irritating as an itch, and he chased him away.

Muub looked down. Pall Mall was the City's main avenue. Broad and light-filled, it was a rectangular corridor cut vertically through the complex heart of Parz - from the elaborate superstructure of the Palace buildings at the topmost Upside, down through hundreds of dwelling levels, all the way to the Market, the vast, open forum at the center of the City. The Reception Gallery was poised at the head of Pall Mall, just below the Palace buildings themselves; Muub, trying to relax in his coc.o.o.n, was bathed in the subtly shaded light filtering down through the Palace's lush gardens, and was able to survey, it seemed, the whole of the City as if it were laid open before him. Pall Mall itself glowed with light from the Air-shafts and wood-lamps which lined its perforated walls; threads of the shafts, glowing green and yellow, converged toward the Market itself, the City's dusty heart. The great avenue - normally thronged with traffic - was deserted today, but Muub could make out spectators peering from doors and viewing-balconies: ordinary little faces turned up toward him like so many flowers. And in the Market itself - all of five thousand mansheights below the Palace - the Tribute procession was almost a.s.sembled, as thousands of common citizens gathered to present the finest fruit of this quarter's labor to the Committee. No coc.o.o.ns down there, of course; instead the Market was crisscrossed by ropes and bars to which people clung with their hands or legs, or hauled themselves along in search of vantage points. To Muub, staring down at the swarming activity, it was like gazing into a huge net full of young piglets.

The Gallery itself was laced with ropes of brushed leather - to guide those Committee members and courtiers, Muub thought sourly, too poor to be simply carried to their coc.o.o.ns. The Gallery's cool, piped Air was scented with fine Crust-flowers. Vice-Chair Hork was already in his place close to Muub, alongside the vacant coc.o.o.n reserved for his father, Hork IV. Hork glared ahead, sullen and silent in his bulk and glowering through his beard. Perhaps half the courtiers were in their places; but they had congregated toward the rear of the Gallery, evidently sensing, in their dim, self-seeking way, that today was not a good day to attract the attention of the mercurial Vice-Chair.

So already the elaborate social jostling had begun. It would be a long day.

In fact - thanks to the recent Glitch - it had already been a long day for Muub. The latest in a series of long days. He was princ.i.p.al Physician to the First Family, but he also had a hospital to run - indeed, the retention of his responsibilities at the Hospital of the Common Good had been a condition of his acceptance of his appointment to Hork's court - and the burden placed on his staff by the Glitch had still to unravel. He studied the vapid, pretty, aging faces of the courtiers as they preened in their finery, and wondered how many more ravaged bodies he would have to tend before sleep claimed him.

Vice-Chair Hork seemed to notice him at last. Hork nodded to him. Hork was a bulky man whose size gave him an appearance of slowness of wit - a deceptive appearance, as more than one courtier had found to his cost. Under his extravagant beard - extravagantly manufactured, actually, Muub reflected wryly - Hork's face had something of the angular n.o.bility of his father's, with those piercing, deep black eyecups and angular nose; but the features tended to be lost in the sheer bulk of the younger Hork's fleshy face, so that whereas the Chair of the Central Committee had an appearance of gentle, rather bruised n.o.bility, his son and heir appeared hard, tough and coa.r.s.e, the refined elements of his looks serving only to accentuate his inherent violence. Today, though, Hork seemed calm. "So, Muub," he called. "You've decided to join me. I was fearful of being shunned."

Muub sighed as he worked his way deeper into his coc.o.o.n. "You glower too much, sir," he said. "You frighten them all away."

Hork snorted. "Then through the Ring with them," he said, the ancient obscenity coming easily to his lips. "And how are you, Physician? You're looking a little subdued yourself."

Muub smiled. "I'm afraid I'm getting a little old for my burden of work. I've spent most of the last few days in the Hospital. We're - very busy, sir."

"Glitch injuries?"

"Yes, sir." Muub rubbed a hand over his shaven scalp. "Of course we should have seen the worst now... or rather, the more serious cases we have not yet reached must, sadly, be beyond our care. But there remains a steady stream of lesser injuries which..."

"Minor?"

"Lesser," Muub corrected him firmly. "Which is very different. Not life-threatening, but still, perhaps, disabling. Most of them patients from the central districts, of course. When Longitude I failed..."

"I know," Hork said, chewing his lip. "You don't need to tell me about it."

Longitude I was an anchor-band, one of four superconducting toroids wrapped around the City to maintain the structure's position over the South Pole. Longitudes I and II were aligned vertically, while their twins Lat.i.tudes I and II were placed horizontally, so that the toroids crisscrossed around the City.

The Glitch had largely spared the Polar regions, the City itself. But at the height of the Glitch, with vortex lines tangling around the City, Longitude I had failed. The City had rattled in its superconducting cage like a trapped Air-pig. The anchor-band's current had been restored quickly, and the effects on the external parts of the structure - such as the Spine and the Committee Palace - had been minimal. But it had been in the hidden interior of the City, where thousands of clerks and artisans toiled their lives away, that the most serious injuries had been incurred.

"Do we have any figures on the casualties yet?"

Muub looked at the Vice-Chair. "I'm surprised you're asking me. I'm your father's Physician, but I'm really just one Hospital Administrator - one of twelve in all of Parz."

Hork waved fat fingers. "I know that. All right, forget I asked. I just wanted your view. The trouble is that the agencies which gather statistics like that for us are precisely those which were wrecked by the Glitch itself." He shook his head, the jowls wobbling angrily. "People think gathering information is a joke - unnecessary. A luxury. I suspect even my highly intelligent father shares that view." The last few words were spat out, venomously. "But the fact is, without such data a government can scarcely operate. I've tried to justify this to my father often enough. You see, Doctor, without central government functions, the state is like a body without a head. We can't even raise t.i.thes successfully, let alone allocate expenditure." Hork grimaced. "It makes today's Grand Tribute look a little pointless, doesn't it, Physician?"

Muub nodded. "I understand, sir."

"I tell you, Muub," Hork said, still nervously chewing on his bearded underlip, "one more Glitch like that and we could be done for."

Muub frowned. "Who are 'we'? The government, the Committee?"

Hork shrugged. "There are plenty of hotheads, out in the ceiling-farms, in the dynamo sheds, in the Harbor... There seems no way of rooting such vermin out. Even Breaking them on the Wheel serves only to create martyrs."

Muub smiled. "A wise observation."

Hork laughed, displaying well-maintained teeth. "And you're a patronizing old fool who pushes his luck... Martyrs. Yet another subtlety of human interaction which seems to evade my poor, absent father." Now Hork looked piercingly at Muub; the Physician found himself flinching. "And you," Hork said. "Do you scent rebellion in the Air?"

Muub thought carefully. He knew he wasn't under any personal suspicion; but he also knew that the Vice-Chair - unlike his father - took careful note of anything said to him. And Hork had dozens, hundreds of informants spread right throughout Parz and its hinterland. "No, sir. Although there are plenty of grumbles - and plenty of folk ready to blame the Committee for our predicament."

"As if we had called the Glitches down on our own heads?" Hork wriggled in his coc.o.o.n, folds of brushed leather rippling over his ample form. "You know," he mused, "if only that were true. If only the Glitches were human in origin, to be canceled at a human command. But then, the scholars tell us - repeating what little wisdom was allowed to survive the Reformation - man was brought to this Mantle by the Ur-humans, modified to survive here. If once we had such control over our destiny, why should we not regain it, ultimately?" He smiled. "Well, Physician?"

Muub returned the smile. "You've a lively mind, sir, and I enjoy debating such subjects with you. But I prefer to restrict my attention to the practical. The achievable."

Hork scowled, his plaited hair-tubes waving with an elegance that made Muub abruptly aware of his own baldness. "Maybe. But let's not forget that that was the argument of the Reformers, ten generations ago. And their purges and expulsions left us in such ignorance we can't even measure the damage they did...

"Anyway, it's not revolt I fear, Physician. It's more the feasibility of government itself - I mean the viability of our state, regardless of whoever sits in my father's chair." The man's wide, fleshy face turned to Muub now, full of unaccustomed doubt. "Do you understand me, Muub? d.a.m.n few do, I can tell you, inside this wretched court or out."

Muub was impressed - not for the first time - by the younger Hork's acuity. "Perhaps, you fear, the Glitches will render an organized society like Parz City impossible. Revolts will become irrelevant. Our civilization itself will fall."

"Exactly," Hork said, sounding almost grateful. "No more City - no more t.i.the-collectors, or Crust-flower parks, or artists or scientists. Or Physicians. We'll all have to Wave off to the upflux and hunt boar."

Muub laughed. "There are a few who would like to see the back of the t.i.thes."

"Only fools who cannot perceive the benefits. When every man must not only maintain his own scrubby herd of pigs, but must make, by hand, by hand, every tool he uses, like the poorest upfluxer... then, perhaps, he will look back on taxation with nostalgic affection." every tool he uses, like the poorest upfluxer... then, perhaps, he will look back on taxation with nostalgic affection."

Muub frowned, scratching at one eyecup. "Do you think such a collapse is near?"

"Not yet," Hork said. "Not unless the Glitches really do smash us wide open. But it's possible, and growing more so. And only a fool closes his eyes to the possible."

Muub, wary of what traps might lie under the surface of that remark, turned to stare down through the dusty, illuminated Air of Pall Mall.

Hork growled, "Now I've embarra.s.sed you. Come on, Muub, don't start acting like one of these d.a.m.n piglet-courtiers. I value your conversation. I didn't mean to imply my father is such a fool."

"...But he does not necessarily share your perspective."

"No. d.a.m.n it." Hork shook his head. "And he won't give me the power to do anything about it. It's frustrating." Hork looked at Muub. "I hear you saw him recently. Where is he?"

Shouldn't you know? "He's at his garden, at the Crust. He can't take the thin Air, of course, so he mostly stays in his car, watching the coolies getting on with their work." "He's at his garden, at the Crust. He can't take the thin Air, of course, so he mostly stays in his car, watching the coolies getting on with their work."

"So he's healthy?"

Muub sighed. "Your father is an old man. He's fragile. But - yes; he is well."

Hork nodded. "I'm glad." He glanced at the Physician, seeking his reaction. "I mean it, Muub. I get frustrated with him because I'm not always sure he addresses the key issues. But Hork is is still my father. And besides," he went on pragmatically, "the last thing we need right now is a succession crisis." still my father. And besides," he went on pragmatically, "the last thing we need right now is a succession crisis."

There was a buzz of conversation from around the Gallery.

Hork leaned forward in his coc.o.o.n. "What's going on?"

Muub pointed. "The pipers are moving into position." There were a hundred of the pipers, dressed in bright, eyecatching clothes, now Waving out of doorways all along Pall Mall and taking up their positions, lining the route of the parade. The closest pipers - four of them, one to each of the Mall's complex walls - were earnest young men, efficiently stoking the small furnaces they carried on belts around their waists. Fine, tapered tubes led from the furnaces in elaborate whorls to wide, flower-like horns; the horns of polished wood gaped above the head of the pipers like the mouths of shining predators.

"There!" Hork cried, pointing down the avenue, his face illuminated with a mixture of excitement and avarice.

Muub, suppressing a sigh, leaned further forward and squinted down the Mall, trying to pick out the distant specks in the Air that would be the approaching Tribute parade: earnest, overweight citizens bearing vast sheaves of wheat, or grotesquely bloated Air-pigs.

The pipers pushed valves on their furnace-boxes. Within each horn, complex Air patterns swirled, sending pulses of heat along the necks of the horns - pulses which emerged from the horns, by a process which had always seemed magical to the resolutely non-musical Muub, as stirring peals of sound.

Far below, in the Market, the crowd roared.

Toba Mixxax twitched his reins and stared unblinking out of his window. "I'm going to take him straight into the Hospital. The Common Good. It's a decent place. Hork's own Physician runs it..."

Cars of all sizes came hurtling past them in a constant, random stream. Pig teams farted clouds of green gas. Speakers blared. Toba yelled back through his own car's system, but the amplified voices were too distorted for Dura to understand what was being said.

It was, frankly, terrifying. Dura, hovering with Farr behind Toba's seat and staring out at the chaotic whirl of hurtling wooden boxes, bit the back of her hand to avoid crying out.

But somehow Toba Mixxax was managing not only to avoid collisions but also to drive them forward - slowly, but forward - to the staggering bulk of the City itself.

"Of course it's not the cheapest. The Common Good, I mean." Toba laughed hollowly. "But then, frankly, you're not going to be able to afford even the cheapest. So you may as well not be able to afford the best."

"Your talk means little, Toba Mixxax," Dura said. "Perhaps you should concentrate on the cars."

Toba shook his head. "Just my luck to come into town with three upfluxers on the day of the Grand Tribute. Today of all days. And..."

Dura gave up listening. She tried to ignore the cloud of hurtling cars in the foreground of her vision, to see beyond them to Parz itself.

The South Magnetic Pole itself was spectacular enough - like a huge artifact, an immense sculpting of Magfield and spin lines. Vortex lines followed - almost - the shape of the Magfield, so it was easy to trace the spectacular curvature of the magnetic flux. It was nothing like the gentle, easy, Star-girdling curvature of her home region, far upflux; here, at the furthest downflux, the vortex lines converged from all over the Mantle and plunged into the bulk of the Star around the Pole itself, forming a funnel of Magfield delineated by sparkling, wavering vortex lines.

And, suspended right over the mouth of that immense funnel, as if challenging the Pole's very right to exist, the City of Parz hung in the Air.

The City was shaped like a slender, upraised arm, with a fist clenched at its top. The "arm" was a spine of wood which thrust upward, out of the Pole's plunging vortex funnel, and the "fist" was a complex ma.s.s of wooden constructions which sprawled across many thousands of mansheights. Four great hoops of some glittering substance - "anchor-bands," Toba called them, two aligned vertically and two horizontally - surrounded the fist-ma.s.s; Dura could see struts and spars attaching the hoops to the ma.s.s of the "fist."

The "fist," the City itself, was a perforated wooden box, suspended within the hoops. Ports - circular, elliptical and rectangular - punctured the box's surface, and cars streamed in and out of many of the ports like small creatures feeding off some greater beast. Toward the base of the City the ports were much wider: they gaped like mouths, dark and rather forbidding, evidently intended for bulk deliveries. Into one of these Dura could see tree-stalks being hauled from a great lumber-jacking convoy.

Sparkling streams, hundreds of them, flowed endlessly from the base of the City and into the Air, quite beautiful: they were sewer streams, Toba told her, rivers of waste from Parz's thousands of inhabitants.

As the car veered around the City - Toba, braying incoherently into his Speaker tube, was evidently looking for a port to enter - Dura caught tantalizing glimpses through the many wide shafts of complex structures, layers of buildings within within the bulk of the City itself. A complex set of buildings perched on the crown of the City, grand and elegant even to Dura's half-baffled eyes. There were even small Crust-trees arcing into the Air from among those upper buildings. When she pointed this out to Toba he grinned and shrugged. "That's the Committee Palace," he said. "Expense is little object if you live that far Upside..." the bulk of the City itself. A complex set of buildings perched on the crown of the City, grand and elegant even to Dura's half-baffled eyes. There were even small Crust-trees arcing into the Air from among those upper buildings. When she pointed this out to Toba he grinned and shrugged. "That's the Committee Palace," he said. "Expense is little object if you live that far Upside..."

Light filled the City, shining from its many ports and casting beams across the dusty Air surrounding it, so that Parz was surrounded by a rich, complex mesh of green-yellow illumination. The City was immense - almost beyond Dura's imagination - but it seemed to her bright, Air-filled, full of light and motion. People swarmed around the buildings, and streams of Air-cars laced around the spires of the Palace. Even the "arm" below the City-fist, the Spine (as Toba called it) that grew down toward the Pole, bore tiny cars which clambered constantly up and down ropes threaded along the Spine's length.

The City grew as they approached - growing so huge, at last, that it more than filled the small window of the car. Dura began to find the whole a.s.semblage overwhelming in detail and complexity. She recalled - with a strange feeling of nostalgia - her feelings of panic on first encountering Toba's car. She'd soon learned to master her panic then, and had come to feel almost in control of this strange, weak person, Toba Mixxax. But now she was confronted by strangeness on an unimaginably huger scale. Could she ever come to terms with all this - ever again take control over her own destiny, let alone influence events around her?

Her discomfiture must have shown in her expression. Toba grinned at her, not unsympathetically. "It must be pretty overwhelming," he said. "Do you know how big the City is? Ten thousand mansheights, from side to side. And that's not counting the Spine." The little car continued to edge its way, cautiously, around the City, like a timid Air-piglet looking for a place to suckle. Toba shook his head. "Even the Ur-humans would have been impressed by ten thousand mansheights, I'll bet. Why, that's almost a centimeter..."

The car entered - at last - a narrow rectangular port which seemed to Dura to be already filled with jostling traffic. The car pushed deeper into the bulk of the City along a narrow tunnel - a "street," Toba Mixxax called it - through which cars and people thronged. These citizens of Parz were all dressed in thick, heavy, bright clothing, and all seemed to Dura utterly without fear of the streams of cars around them. Dura's impressions from without of the airiness and brightness of the City evaporated now; the walls of the street closed in around her, and the car seemed to be pushing deeper into a clammy darkness.
