Xeelee: An Omnibus: Raft, Timelike Infinity, Flux, Ring

by Stephen Baxter

  Over time, some contact - a kind of implicit trade - opened up between the inhabitants of the lower levels and the jungle folk. But there was no incursion from below, no will to break open Deck Zero. And so, with iron determination, Uvarov enforced his huge experiment, century after century.

  Arrow Maker and Spinner-of-Rope - face-painted, young-old pygmies were the extraordinary result.

  Milpitas listened, apparently bemused, as Uvarov ranted. ‘When I started this work the average lifespan, without AS, was about a hundred. Now we have individuals over two hundred and fifty years old . . . ’ Spittle looped across his toothless mouth. ‘A thousand AS years isn’t enough. Ten thousand wouldn’t suffice. I’m talking about changing the nature of the species, man . . .’

  Milpitas laughed at him. ‘Was there ever a more obsessive control of any unfortunate population than that? To deny the benefits of AS to so many generations—’ The Planner shook his bare, scarred head. ‘To waste so much human potential, so many “mute, inglorious Miltons” . . .’

  ‘I’m transforming the species itself,’ Uvarov hissed. ‘And it’s working, damn you. Arrow Maker, here—’ he cast about vaguely ‘- is eighty years old. Eighty. Look at him. By successively breeding out the lethal genes, I’ve—’

  ‘If your programme was so laudable, then why did you feel it necessary to barricade yourself into the forest Deck?’

  Morrow, helpless, felt as if he had wandered into an old, worn-out argument. He remembered his last interview with Milpitas, in which Milpitas had - calmly and consistently - denied the reality of the society above Deck One: a society whose independent existence had been obvious long before Arrow Maker and the others came firing darts down through the opened hatches of the Locks. And now - even when confronted with Uvarov and these painted primitives - Milpitas seemed unable to break away from his own restricted world-view.

  Uvarov was noisy, of alien appearance, visibly half-insane, and locked inside a partial, incomplete - yet utterly inflexible - mind-set. Milpitas, by contrast, was calm, his manner and speech ordered, controlled. And yet, Morrow reflected uneasily, Milpitas was, in his way, just as rigid in his thinking, just as willing to reject the evidence of his senses.

  We’re a frozen society, Morrow thought gloomily. Intellectually dead. Maybe Uvarov is right about mind-sets. Perhaps we’re all insane, after this long flight. And yet - and yet, if Uvarov is correct about the end of the flight - then perhaps we can’t afford to remain this way much longer.

  With a sense of desperation, he turned to Milpitas. ‘You must listen to him. The situation’s changed, Planner. The ship—’

  Milpitas ignored him. He looked weary. ‘I’m growing bored with this. I will ask my question once more. And then you will leave. All of you.

  ‘Uvarov, why have you come here?’

  Uvarov wheeled his chair forward; Morrow heard a dull thud as the chair frame collided softly with Milpitas’ desk. ‘Survivalist,’ he said, ‘the journey is over.’

  Milpitas frowned. ‘What journey?’

  ‘The flight of the Great Northern. Our odyssey through time, and space, to the end of history.’ His ruined face twisted. ‘I hate to admit it, but our factionalism serves no more purpose. Now, we have to work together - to reach the wormhole Interface, and—’

  ‘Why,’ Milpitas asked steadily, ‘do you believe the journey is over?’

  ‘Because I’ve seen the stars.’

  ‘Impossible,’ Milpitas snapped. ‘Your eyes are gone. You’re insane, Uvarov.’

  ‘My people—’ Uvarov’s voice dried to a croak. Spinner-of-Rope stepped forward, took a wooden bowl of water from a rack within the body of the chair, and allowed a little of the fluid to trickle into Uvarov’s cavern of a mouth.

  ‘My people are my eyes,’ Uvarov said, gasping. ‘Arrow Maker climbed the tallest tree and studied the stars. I know, Milpitas. And I understand.’

  Milpitas’ eyes narrowed. ‘You understand nothing.’ He glanced, briefly and dismissively, at Arrow Maker, who returned his look with cool calculation. ‘I’ve no idea what this - person - saw, when he climbed his tree. But I know you’re wrong, Uvarov. We’ve nothing to discuss.’

  ‘But the stars - don’t you see, Milpitas? There was no starbow. The relativistic phase of the flight must be over . . .’

  Milpitas smiled thinly. ‘Even now, through the fog that has swamped your intellect, you’ll probably concede that one great strength of the bureaucracies you despise so much is record-keeping.

  ‘Uvarov, we keep good records. And we know that you’re wrong. After all this time there’s some uncertainty, but we know that the thousand-year flight has at least half a century to run.’

  Something stirred in Morrow’s heart at that. Somehow, he suspected, he’d never quite believed Uvarov’s pronouncement - but the authority of a Planner was something else. Just fifty years . . .

  ‘You’re a damn fool,’ Uvarov railed; his chair jerked back and forth, displaying his agitation.

  Milpitas said coolly, ‘No doubt. But we’ll cope with journey’s end when it comes. Now I want you out of my office, old man. I have more than enough work to do without—’

  Morrow couldn’t help but come forward. ‘Planner. Is that all you have to say? The first contact between the Decks for hundreds of years—’

  ‘And the last, if I’ve anything to do with it.’ Milpitas raised his face to Morrow; his remodelled flesh was like a sculpture, Morrow thought abstractedly, a thing of cold, hard planes and edges. ‘Get them out of here, Morrow. Take them back to their jungle world.’

  ‘Was I wrong to bring them here?’

  ‘Get them out.’ Tension showed in Milpitas’ voice, and the prominence of the muscles in his neck. ‘Get them out.’

  She wondered how she must appear to these photino creatures.

  They would find it as difficult to perceive baryonic matter as she, a baryonic creature, found it to see them. Perhaps the birds saw a pale tetrahedron, the faint dark-matter shadow of the exotic matter Interface framework which formed the basis of her being. Perhaps they caught some dim sense of the wormhole itself, the throat of space and time through which she pumped away the heat which would otherwise destroy her.

  The old theories had predicted dark-matter particles colliding with the swarming protons of the Solar core, absorbing a little of their energy and so transporting heat out from the fusing heart. This was how, it was thought, dark matter cooled the Sun.

  She saw now that these notions had been right in essence, but too crude. The birds absorbed Solar heat energy. They fed on interactions with protons in the plasma. Incorporating energy from photino-proton interactions within their structures, the birds grew, and spiralled out from the hotter, denser heart of the Sun, taking the heat energy with them.

  The ancient theorists had envisaged a particle-based physical process to extract core heat, and so suppress the fusion processes there. The truth was, the birds fed on the Sun’s heat.

  And, by feeding - like unwise parasites - they would eventually kill their host.

  Unwise - unless, of course, that had been the intention all along.

  Lieserl had learned about the Qax.

  The Qax had originated as clusters of turbulent cells in the seas of a young planet. Because there were so few of them the Qax weren’t naturally warlike - individual life was far too precious to them. They were natural traders; the Qax worked with each other like independent corporations, in perfect competition.

  They had occupied Earth simply because it was so easy - because they could.

  The only law governing the squabbling junior races of the Galaxy was, Lieserl realized, the iron rule of economics. The Qax enslaved mankind simply because it was an economically valid proposition.

  They had to learn the techniques of oppression from humans themselves. Fortunately for the Qax, human history wasn’t short of object lessons.

  The wormhole station maintaining contact with Lieserl was abandoned, once again, durin
g the Qax occupation.

  Finally the Qax were overthrown. The details hadn’t been clear to Lieserl; it was something to do with a man named Jim Bolder, and an unlikely flight in a stolen Xeelee derelict craft, to the site of the Xeelee’s greatest project: the Ring . . .

  This was the first time Lieserl had heard of the Ring.

  After the overthrow, once more humans returned to the Sun, and restored contact with the ageing, increasingly incongruous artifact that contained Lieserl.

  This time, Lieserl was shocked by the humans who greeted her.

  The Qax, during the occupation, had withdrawn AntiSenescence technology. Death, illness, had returned to the worlds of mankind. It hadn’t taken long for toil and disease to erase most of the old immortals - some of whom had still remembered the days before the Squeem, even - and, within a few generations, humans had forgotten much of their past.

  The discontinuity in human culture after the Qax was immeasurably greater than that arising from the Squeem occupation. The new people who emerged from the Qax era - and who now peered out of sketchy images at Lieserl in her cocoon of Solar plasma - seemed alien to her, with their shaven heads and gaunt, fanatical expressions.

  Expansion had begun again, but this time fuelled by a hard-edged determination. Never again would humanity be made to serve some alien power. Lieserl in her whale-dream, watching centuries flicker by in fragments of image and speech, saw humans erupt out of their systems once more. A new period began - a period called the Assimilation.

  During the Assimilation, humans - aggressively and deliberately - absorbed the resources and technologies of other species.

  Human culture evolved rapidly in this period. The link with Lieserl was maintained, but with increasingly long interruptions. The motivation of these remote humans seemed to be a brand of hostile curiosity; she saw only calculation in the faces presented to her. She was seen, she suspected, only as another resource to be exploited for the continuing, endless expansion of mankind.

  Soon - astonishingly quickly - humans became the dominant of the junior races. Humanity’s growth in power and influence grew exponentially.

  At last, only the Xeelee themselves were more potent than mankind . . . And the legend of the Xeelee’s achievements - the construction material, the manipulation of space and time, the Ring itself - grew into a deep-rooted mythology.

  Then, for the last time, her wormhole telemetry link was shut down.

  Drifting through her endless, unchanging ocean of plasma, she felt a distant twinge of regret - a feeling that soon dispersed into the peaceful, numb silence around her.

  Humans had become alien to her. She was better off without them.

  The birds must have some lifecycle, she thought; a circle of birth and life and death, much like every baryonic creature. Individual photino birds moved past her too rapidly to follow; but still, she studied them carefully, and was rewarded with glimpses - she thought - of growth.

  Eventually she saw a bird reproduce.

  She could see there was something unusual about this bird, even as it approached. The bird was fat, swollen with proton heat-energy. It seemed somehow more solid - more real, to Lieserl’s baryonic senses - than its neighbours.

  The bird shuddered - once, twice - its lenticular rim quivering. She almost felt some empathy with the creature; it seemed in agony.

  Abruptly - startling Lieserl - the bird shot away from its orbital path. It hovered for a moment - then it hurtled down into the heat-rich core of the Sun once more. Lieserl’s processors told her that the bird seemed a little less massive than before.

  And it had left something behind.

  Lieserl enhanced her senses as far as they would go. The mother-bird had left behind a copy of herself - a ghostly copy, rendered in clumps of higher density in the plasma proton-electron mix. It was a three-dimensional image of the mother, in baryonic matter. Within fractions of a second the clumps had started to disperse - but not before more photinos had clustered around the complex pattern of baryonic matter, rapidly plating over its internal structure.

  The whole process took less than a second. At the end of it, a new photino bird, sleek and small, moved away from the site of its birth; the last traces of the higher-density baryonic material left behind by the mother bird drifted away.

  Lieserl ran the image sequence over and over. As a method of reproduction, it was a long way from any Earth-bound form - even cloning. It was more like making a straight copy - an imprint from a three-dimensional mould, mediated by baryonic matter.

  The newborn must be an almost exact copy of its parent - more exact than any clone, even. Presumably it carried a copy of its parent’s memories - even, perhaps, of its awareness . . .

  And, presumably, a copy too of the generation before that - and before that, and . . .

  Lieserl smiled. Each photino child must carry within it the soul of all of its grandmothers, a deep tree of awareness reaching right back to the dawn of the species.

  And all mediated by baryonic matter, she thought wonderingly. The birds depended on the relative transparency of dark and baryonic matter to take their detailed, three-dimensional copies of themselves.

  But this meant, she realized, that the photino birds could only breed in places where they could find high densities of baryonic matter. They could only breed in the hearts of stars.

  She replayed the birth images, over and over.

  There was something graceful, immensely appealing, about the photino birds, and she found herself warming to them. Spiritually she felt much closer to the birds, now, than to the hard-eyed humans of the Assimilation, beyond the Solar ocean.

  She hoped her theory - that the birds were deliberately destroying the Sun - was wrong.

  The return journey seemed much longer. Morrow felt angry, disappointed, weary. ‘I can’t understand how Milpitas reacted.’ He shook his head. ‘It’s as if he didn’t even see you people . . .’

  ‘Oh, I understand.’ Uvarov twisted his head. ‘I understand. We are all too old, you see. In a way Milpitas was right about me; after all I share some of these flaws myself.’ Uvarov’s voice, while still distorted by age, was calmer, more rational than at any point during the interview with Milpitas, Morrow thought.

  Uvarov went on, ‘But at least I can recognize my limitations - the tunnel-vision of my age and condition. And, by recognizing it, deal with it.’

  Spinner-of-Rope had been leading the way up the hundred-yard ramp to Deck One. Now, as she neared the top, she slowed. Her hand dropped, seemingly automatically, to her blowpipe and the little sack of feathered darts at her waist.

  ‘What is it?’ Morrow asked drily. ‘More problems with human body odour?’

  She turned, her eyes huge behind her spectacles. Not that. But something . . . Something’s wrong.’

  Arrow Maker raised his face. ‘I can smell it, too.’

  ‘Describe,’ Uvarov snapped.

  ‘Sharp. Smoky. A little like fire, but more intense . . .’

  Uvarov grunted. He sounded somehow satisfied. ‘Cordite, probably.’

  Arrow Maker looked blank. ‘What?’

  They reached the top of the ramp. Hastily, with both forest people bearing their weapons in their hands, they made for the Lock down which Uvarov had been carried.

  As they approached the Lock, they slowed, almost as if synchronized. The three of them - Arrow Maker, Morrow and Spinner - stood and stared at the Lock.

  Uvarov twisted his face to left and right. ‘Tell me what’s wrong. It’s the Lock, isn’t it?’

  ‘Yes.’ Morrow stepped forward cautiously. ‘Yes, it’s the Lock.’ The cylinder of metal had been burst open, somewhere near its centre; bits of its fabric, twisted, scorched, none larger than his hand, lay scattered across the Deck surface. There was a stink of smoke and fire - presumably Uvarov’s cordite.

  Arrow Maker stood clutching his bow, open-mouthed, impotent. Spinner ran off towards the next Lock, her bare feet padding against the metal floor.
/>
  Uvarov nodded. ‘Simple and effective. We should have expected this.’

  Morrow bent to pick up a piece of hull metal; but the twisted, scorched fragment was still hot, and he withdrew his fingers hastily.

  Spinner came running back. She looked breathless, wide-eyed and very young; she stood close to her father and clutched his arm. ‘The next Lock’s been blown out as well. I think they all have. The Locks are impassable. We can’t get home.’

  Uvarov whispered, ‘We should check. But I am sure she is right.’

  Morrow slammed his fist into his palm. ‘Why? I just don’t understand. Why this destruction - this waste?’

  ‘I told you why,’ Uvarov said evenly. The existence of the upper level was an unacceptable challenge to the mind-set of Milpitas and the rest of your damn Planners. I doubt if they will have done any damage to the forest Deck itself. Sealing it off - sealing it away from themselves, apparently forever - should do the trick just as well.’

  ‘But that’s insane,’ Morrow protested.

  Uvarov hissed, ‘No one ever said it wasn’t. We’re human beings. What do you expect?’

  Arrow Maker paced about the floor. Morrow became aware, nervously, of the muscles in the back of the little man which flexed, angrily; Maker’s face paint flared. ‘Whether it was intended or not, we’re trapped here. We’re in real danger. Now, what in Lethe are we going to do?’

  Morrow’s fear seemed to have been burned out of him by his anger at the foolishness, the wastefulness of the destruction of the Locks. ‘I’ll help you. I’ll not abandon you. I’ll take you to my home - I live alone; you can hide there. Later, perhaps we can find some way to open up a Lock again, and—’

  Arrow Maker looked grateful; but before he could speak Uvarov wheeled forward.

  ‘No. We won’t be going back to the forest.’

  Arrow Maker said, ‘But, Uvarov—’

  ‘Nothing’s changed.’ Uvarov turned his blind face from side to side. ‘Don’t you see that? Arrow Maker, you saw the stars yourself. The ship’s journey is over. And we have to go on.’
