But Adda was still troubled by the light change. He scoured the horizon, cursing the distortion of the clearwood wall before him.
Then he saw it.
Far upflux, far to the north, the vortex lines had disappeared.

With standard humans.
Dura and Hork looked at each other. He hissed, "How much of this do you understand?"
Dura stared at Karen Macrae. The floating image had drifted away from the center of the cabin, now, and seemed to be growing coa.r.s.er; it was not a single image, in fact, but a kind of mosaic formed by small, jostling cubes of colored light. Dura asked, "Are you an Ur-human?"
Karen Macrae fizzed. A what? Oh, you mean a standard human. No, I"m not. I was, though... A what? Oh, you mean a standard human. No, I"m not. I was, though...
Karen Macrae and five hundred others had come to the Star from - somewhere else. Mars, perhaps, Dura thought. They had established a camp outside the Star. When they"d arrived the Star had been empty of people; there were only the native lifeforms - the pigs, the rays, the spin-spiders and their webs, the Crust-trees.
Karen Macrae had come to populate the Star with people.
The structure of a neutron star is astonishingly rich, whispered Karen Macrae. whispered Karen Macrae. Do you realize that? I mean, the Core is like a huge, single nucleus - a hypernucleus, laced with twenty-four percent hyperonic matter. And it"s fractal. Do you know what that means?

And it"s fractal. Do you know what that means? It has structure on all scales, right down to the...
"Please." Hork held up his hands. "This is a storm of words, conveying - nothing."
The blocks of Karen"s face jostled like small insects. I am a first-generation Colonist, I am a first-generation Colonist, she said. she said. We established a Virtual environment in the hypernucleus - in the Core. I was downloaded via a tap out of my corpus callosum - downloaded into the environment here, in the Core.

Do you understand me? Do you understand me?
Hork said slowly, "You are - a copy. Of an Ur-human. Living in the Core."
Dura said, "Where is the Ur-human Karen Macrae? Is she dead?"
She"s gone. The ship left, once we were established here. I don"t know where she is now... Dura tried to detect emotion in the woman-thing"s voice - was she resentful of the original who had made her, who had thrust her into the Core of the Star? Was she envious? - but the quality of the voice was coa.r.s.e, too harsh to tell; Dura was reminded of the Speaker system on Toba Mixxax"s Air-car.

The colony of human copies, downloaded into the Core, had devices which interfaced with the physical environment of the Star, the woman-thing told them. They had a system to produce something called exotic matter; they laced the Mantle with wormholes, linking Pole to Pole, and they built a string of beautiful cities.
When they"d finished, the Mantle was like a garden. Clean, empty. Waiting.
Dura sighed. "Then you built us."
"Yes," Hork said. "Just as our fractured history tells us. We are made things. Like toys." He sounded angry, demeaned.
The world had been at peace. There had been no need to struggle to live. There were no Glitches (few, anyway). The downloaded Colonists, still residing in the Core, had been there for the Human Beings like immortal, omniscient parents.
One could Wave from upflux to Pole, through the wormhole transit ways, in a heartbeat.
Hork pushed forward, confronting the woman-thing. "You expected us to come here, to seek you."
We hoped you would come. We could not come to you.
"Why?" He seemed to be snarling now, Dura thought, unreasonably angry at this ancient, fascinating woman-sh.e.l.l. "Why do you need us now?"
Karen Macrae turned her head. The light-boxes drifted, colliding noiselessly - no, Dura saw, they drifted through each other, as smoothly as if they were made of colored Air.
The Glitches, she said slowly. she said slowly. They are damaging the Core... they are damaging us. They are damaging the Core... they are damaging us.
Dura frowned. "Why don"t you stop them?"
We haven"t a physical Interface any more. We withdrew it. Karen"s voice was growing more indistinct, her component blocks larger; the form of a human was gradually being submerged in loss of detail. Karen"s voice was growing more indistinct, her component blocks larger; the form of a human was gradually being submerged in loss of detail.
Hork pushed himself forward from the cabin wall, his heavy hands outspread against the wood. "Why? Why did you withdraw? You built us, and took away our tools, and abandoned us. You waged war against us; you took our treasures, our heritage. Why? Why?" Why?"
Karen turned to him, her mouth open, purple boxes streaming from her coa.r.s.ely defined lips. She expanded and blurred, the boxes comprising her image swelling.
Hork threw himself at the image. He entered it as if it were no more than Air. He batted at the drifting, crumbling light-boxes with his open palms. "Why did you make us? What purpose did we serve for you here? Why did you abandon us?" "Why did you make us? What purpose did we serve for you here? Why did you abandon us?"
The boxes exploded; Dura quailed from a monstrous, ballooning image of Karen Macrae"s face, of the pale forms infesting her eyecups. There was a soundless concussion, a flood of purple light which filled the cabin before fleeing through the walls of the ship and into the ocean beyond. The human-thing, the simulacrum of Karen Macrae, was gone. Hork twisted in the Air, punching at emptiness in his frustration.
But there were new shadows in the cabin now, blue-green shadows cast by something behind Dura. Something outside the ship. She turned.
The object was a tetrahedron, she recognized immediately; a four-faced framework of glowing blue lines, like fragments of vortex lines. Sheets of gold, rippling, glistened over the faces. The construct was perhaps ten mansheights to a side, and its faces were easily wide enough to permit a ship the size of the "Pig" to pa.s.s.
It was a gate. A four-sided gate...
Dura felt like a child again; she found a smile, slow and heavy with wonder, spreading across her face. This was a wormhole Interface, the most precious of all the treasures lost in the Core.
It could be a gateway out of the Star.
She grabbed at Hork"s tunic, wonder flooding out her fear. "Don"t you understand what it means? We"ll be able to travel, to cross the Star in a moment, as we could before the Wars..."
He pushed her away roughly. "Sure. I understand what this means. Karen Macrae can"t stop the Glitches. And so - for the first time since dumping us in the Mantle all those years ago, since leaving us to our fate - she and her Core-infesting friends need us. We - you and I - are going to have to travel through that thing, to wherever it takes us, and stop the Glitches ourselves." stop the Glitches ourselves."
22.
CRIS MIXXAX CLIMBED ONTO his board. The wood under his bare feet was polished, warm, familiar; his soles gripped the ridged surface, and the ribs of Corestuff embedded in the wood felt like cold, hard bones. He flexed his knees experimentally. Electron gas hissed around his ankles and toes as the board cut through the flux lines. The Magfield felt springy, solid.
Cris grinned savagely. It felt good. good. It all felt good. At last this day had come, and it was going to be his. It all felt good. At last this day had come, and it was going to be his.
The sky was a huge diorama, all around him. The South Pole, with its brooding purple heart sunk deep in the Quantum Sea, was almost directly below him; he could feel the ma.s.sive Polar distortion of the Magfield permeating his body. Above him the Crust seemed close enough to touch, the dangling Crust-trees like shining hairs, immensely detailed; patterns of cultivation showed in rectangular patches of color and texture - sharp, straight-line edges imposed by humans on the vibrant nature of the Star.
The City hovered in the Air over the Pole. Parz was so far below him he could cover it with the palm of his hand, and imagine he was alone in the sky - alone, save for his fellow racers. Parz looked like some elaborate wooden toy, surrounded by its cage of shining anchor-bands and pierced by a hundred orifices from which the green light of wood-lamps seeped, sickly. Sewage cascaded steadily from its underside, around the Spine of the Harbor. He could see the shining bulge that was the Stadium; it clung to the City"s upper lip like a fragile growth, with the Committee Box a colorful balcony over it. Somewhere in there his parents would be watching, he knew - praying for his success, he"d like to think. But perhaps they were wishing he might fail - give up this dream, this distraction of Surfing, and join them in their quiet, constrained lives once more.
He shook his head, staring down on the City as if he were some G.o.d, suspended over it. Out here the inwardness, the frustration of his life in and around the City, seemed remote, reduced to the trivial; he felt exalted, able to view it all with compa.s.sion, balance. His parents loved him, and they wanted what was best for him - as they saw it. The cries of the race marshals, tiny in the huge, glowing sky, floated to him. Almost time. Almost time. He glanced around. There were a hundred Surfers, drawn into a rough line across the sky; now they were drawing precisely level, into line with the squads of marshals in their distinctive red uniforms. Cris flicked at his own board, once, twice; he felt it kick at the Magfield and bring him exactly into his place in the line. He stared ahead. He was facing along the direction of the vortex lines, toward the rotation pole; the closest line was a few mansheights from him, and the lines swept around him like the walls of some intangible corridor, beckoning him to infinity.

He was facing along the direction of the vortex lines, toward the rotation pole; the closest line was a few mansheights from him, and the lines swept around him like the walls of some intangible corridor, beckoning him to infinity.
The challenge of the race was to Surf along the vortex lines, far across the roof of the world - across the Pole - to a finishing cross-section; there another group of marshals marked out an area of the sky, like human spin-spiders. The race was won - not just by the fastest, the first to complete the course - but by whoever applied the most technical skill, the most style in following the course.
He looked along the line. Ray, he knew, was three places down from him - the only other of his friends to have qualified for the Games this year. There she was, her lithe, bare body coiled over her board, her hair swept back and her teeth shining in a broad, hungry grin. He caught her eye, and she raised a fist, her smile broadening.
The Surfers were all in place now; he saw how they settled over their boards, concentrating, spreading their feet and lifting their arms. The marshals continued to scurry around the line like worried little animals, checking positions, adjusting boards with small pushes and shoves. Silence spread along the line; the marshals were withdrawing. Cris felt his senses open up. The board under his feet, the fizz of the Magfield, the freshness of the Air so far from the womb of the City as it sighed through his mouth and capillaries - these were vital and real things, penetrating his head; he had never felt so alive. alive.
And perhaps, a distant, unwelcome part of him said, he never would again.
Well, if that was to be so - if his life was to be a long-drawn-out anticlimax after this superb moment - then let it be; and let this be his finest time.
The marshals glanced along their line at each other. In unison they raised their right arms - and brought them down with a chop, a cry of "Begin"!
Cris thrust savagely at his board. He felt the Magfield surge through the board and his limbs, dragging at the currents of charged particles there. He lunged forward with a roar, lancing through the Air. The tunnel of vortex lines seemed to explode outward around him; blue-white electron gas sparkled over his body. He was half-aware of similar yells around him, from the rest of the line, but he shut out the other Surfers; he focused on his board, the Magfield, his balance and position in the Air.
The line of marshals, ragged and breaking up, hurtled beneath him.
He opened his mouth and yelled again, incoherent. In his peripheral vision he saw that only Ray, and one or two others, had matched his start. He was in the lead, already ahead of the other Surfers! And he knew his style was good, his balance right; the Magfield surged through his body like a wave of heat. He raised a hand before his face and watched electron gas shower from his fingertips; shrouded in blue light he must look like a figure from a dream racing across the sky...
His board slammed upward, into his feet.
He gasped, almost thrown off the board with the shock. It had been like hitting something solid in the Magfield. He let his knees bend, trying to absorb the upward surge; but still he was hurled up into the Air, balanced perilously on his board. The vortex lines slid down the sky around him, and the Magfield flux lines tore at his stomach and chest as he was dragged brutally across them.
He heard screams from the Surfers around him.
The surge pa.s.sed. Shaken, his knees and ankles aching, he straightened up. He risked glances to left and right. The line of Surfers was ragged, scattered, broken up. Whatever had caused that surge had hit the others as hard as it had him.
...Ray had gone. He saw a glinting sparkle which might have been her board, turning end over end through the Air; but of the girl herself there was no sign.
He felt a stab of concern - an awful, unfamiliar sense of waste waste - but the feeling was drowned by a flood of triumph. By luck or skill, or both, he had survived. He was still on his board, still in the race, and still determined to win. - but the feeling was drowned by a flood of triumph. By luck or skill, or both, he had survived. He was still on his board, still in the race, and still determined to win.
But there was still something wrong. He was drifting downward through the hexagonal array of lines. He corrected his line of flight, pushed himself hard along the Magfield - but again there came that d.a.m.nable drift downward. He felt confused, disoriented, as if his instincts were betraying him.
...No, he realized slowly; his instincts, his skill, were fine. He was holding his line. The vortex lines themselves were drifting upward, toward the Crust. The vortex lines themselves were drifting upward, toward the Crust.
He was a City boy, but he knew what that meant.
The Mantle was expelling its rotational momentum. Glitch. Glitch.
Suddenly, for the first time, he felt lost, vulnerable, alone in the sky. He couldn"t help but cry out, longing to be back in the remote wooden womb of Parz.
He forced himself to concentrate. He wasn"t in any direct danger yet. With luck, and skill, he could still get through this.
Still he pushed across the sky, keeping in line with the drifting vortex lines. But now he slowed a little, glancing around. He was virtually alone now; of the hundred starters in the race, perhaps thirty were still on their boards, paralleling his path through the Air. Of the rest - of the marshals - there was no sign. The City still hung in the Air like a dusty lantern, solid and unperturbed.
The vortex lines were drifting faster. They looked tangled, untidy. Looking more closely he saw instabilities searing along the lines from both upflux and downflux; the huge, complex waveforms pa.s.sed through each other, seeming to drag and reinforce each other.
He looked over his shoulder at the far upflux. There the Air glowed yellow, empty. No vortex lines at all. No vortex lines at all.
Now purple light flooded up through the Air, sudden, shocking, so that his board cast a shadow over his legs and arms. He leaned over his board, glanced down.
The Quantum Sea had exploded, right under the City; a neutrino fount rose steadily toward Parz, like an immense fist.
Resentment flooded Cris. No, No, he thought. he thought. Not today. Not on my day... Not today. Not on my day...
The Magfield surged again, ramming upward into his board with force and immediacy.
I was winning! Oh, I was winning!
Like a fragment of food swimming toward its own consumption, the crude wooden cylinder with its precious cargo of people and animals labored toward the unblemished mouth of the Ur-human artifact.
Dura worked with the Air-pigs, feeding and patiently soothing as their farts drove the turbine. To bring the "Pig" to the wormhole mouth Hork had taken the ship through a long, flat sweep to a position above one facet of the Interface. Through the wide windows she watched the wormhole gate sink briefly into the turgid glimmering of the underMantle, to reemerge as if surfacing as they approached it once more.
Now the Interface rose toward them, like an outstretched hand framed in the clearwood panel set into the base of the ship; within it light flashed, impossibly distant and vortex-line blue.
Hork worked his controls with savagery. For all his outer flippancy in the earlier stages of the voyage, he seemed to have become enraged since the encounter with Karen Macrae. Or perhaps that anger had been there in him all along, Dura thought; perhaps he had always resented the position of humans, left stranded and helpless in this Star. But now, for the first time, he had a focus for that rage: Karen Macrae, and her intangible Colonist companions in the Core of the Star.
Dura wondered at her own composure. She was fearful, yes; and an inner fluidity threatened to overwhelm her as she stared into the approaching maw of the wormhole. But at the same time, she realized, she was not confronting the unknown, she was not confronting the unknown, as was Hork. The lore of the Human Beings was calm, detailed and a.n.a.lytical. The universe beyond the Star, the universe of the past beyond the here-and-now: those realms were abstract, remote, but they were as real to Dura as the world of Air, pigs, trees. Although she had never seen them she had grown up with the Xeelee and their works, with the artifacts of the Ur-humans, and to her they were no more exotic than the wild Air-boars of the Crust. as was Hork.

Perhaps, in the end, the lore of the Human Beings - their careful, almost obsessive, preservation of apparently useless knowledge from the past - was actually a survival mechanism.
The Interface was very close now, Dura saw; the fine, perfect vertices of the upper face spread away from the curving window of the ship, and the rest of the frame was foreshortened by perspective.
Then the clean lines of the artifact began to slide across across the windows of the ship, as slow as knife-blades drawn across skin. The ship"s downward trajectory had been carrying it steadily toward the center of the face; but now they were clearly drifting, sliding toward one knife-sharp edge. the windows of the ship, as slow as knife-blades drawn across skin. The ship"s downward trajectory had been carrying it steadily toward the center of the face; but now they were clearly drifting, sliding toward one knife-sharp edge.
Something was wrong.
Hork hauled at his levers and slammed his hand into the fragile console. "d.a.m.n it. She won"t respond. The Magfield here is disrupted - maybe by the presence of the Interface - and..."
"Look!" Dura pointed downward.
Hork stared at the edge, its fizzing blue light painting deep, shifting shadows on his face as it approached. He swore. "It"s going to hit us."
"We might be safe. Maybe the Ur-humans designed this wormhole to be as safe as possible; maybe the ship will just rebound, and..."
"Or maybe not. Maybe the Ur-humans didn"t expect anyone to be stupid enough to go careering through their doorway in a wooden ship. I think that d.a.m.n thing is going to cut us in two."
The Interface edge, wheeling past the windows, had widened from the abstraction of a line into a glowing rod as broad as a human arm.
Dura wrapped her arms around herself. Behind her the pigs were a comforting, warm ma.s.s, an oasis of familiarity. "At least try, d.a.m.n you. Maybe you can get a purchase on the Interface"s magnetic field."
Now, beyond the walls of the ship, there was a spectacular flash, a sudden storm of blue-white light which flooded the cabin and made her cry out. The pigs squealed, terrified again. The ship lurched. Hork rolled in his seat and Dura grabbed at the pigs" restraining harness.
"We"ve hit!" she cried.
Hork dragged at his levers. "No. It"s the ship"s own field; it must be brushing against the edge... The ship"s responding. Dura, I think you"re right; I think we"re starting to work against the artifact"s field. Keep feeding those animals, d.a.m.n you!"
