Perhaps her train.
The unbidden thought was like a flash-freezing of the spleen.
My train. My people. I could wave and cheer and shout. I could send down flares, I could throw lightning, I could explode whole stars and they still wouldn't know it was me. They wouldn't even look up from the track and drive levers. Do they even think about me?
Taal did. Great Taal, mother of grandmothers. Taal would have heard her, noticed her, received her message. But Taal was in Molesworth and she was up here on the way to Grand Valley with no way of telling a soul living or astral.
Sweetness watched the train out of sight among the other scintilla of the scarp land, then settled back in her harness and did not look at the ground again.
This time, she caught herself just as she was dropping off with a convulsive judder.
Dropping off!
She decided she would look at the stars. There was nothing to make her feel track-sick in those original patterns of light in the darkness. On the long night runs she had learned the names of the major constellations from her mother, but most of the night sky was just lights to her, patternless and magical. Sweetness knew the Cup, and the Dogs, and the Hunting Cat, but the nomenclature seemed tenuous and arbitrary. The Cup could as easily be the Diaphragm; the Hunting Cat, the Bouquet of Oddly Shaped Lilies. Who had these men been, whose particular visions became imprinted on the night sky? Sweetness amused herself down toward midnight by drawing up new constellations and naming them. That wasp-waisted configuration could be the Hornet, or, if you extended it to those three bright stars up there, the Nasty Vase. Just beneath it lay the Angular Banjo, to the left of it, hovering on the dawnward horizon, the Banyan. That band of silver; fainter, softer, broader than the moonring, was the Great Southern Railroad, that tight collection of eleven stars the Sunshine Express. Just visible under the rim of the canopy, the Really Little Church, at eleven o'clock to it, Snortus the Hog. Rolling along the upper rim of the moonring, the Hoop and Stick, behind it, in zodiacal procession, the Typewriter, the Star-Goat, Zelda the Cheap Woman, the Yawning Man, the Open Newspaper; the Five Tickets, the Pram, the Safety Pin, the Letter B, the Big Slipper, the Wishbone.
As she was about to set to work naming the southern constellations, a star fell out of the Letter B, transforming it into a P. It burned brief and bright to the east, a streak of swift fading silver light. While it ebbed from her eyeballs, three more plummeted out of moonring in close formation. They kindled and burned on the southern horizon. Then all three legs of Marco the Three-Legged Pig came off and blazed across the night like a firework display.
While Sweetness gaped, half-wondering if the Powers and Dominions had taken offence at her renaming them, the moonring blazed lilac. The band around the world was a loom of lasers: beams flickered and duelled, parried, stabbed, cut. Sweetness cried out in astonishment as the sky burned, almost let slip her hold on the heat-exchanger. Stars burst, bright enough to light the land beneath like day. Others hurtled on mad trajectories across the orbital marches to die in searing light, slashed apart by scythes of lilac light. Fleets and squadrons moved in from the outer constellations toward the edge of the affray: crimson struck back at lilac. A hundred novas burned on Sweetness's retinas. Stars fell from heaven by the legion, scoring the sky as if fingernails had left love-scratches in the bowl of night to the ur-light beyond. By the lights of any and every of her world's plethora of religions, this was the big one. God the Panarchic, the Ekaterina Angelography, the Seven Sanctas, the Thrones and Dominions, the Orders Lofty and Lesser together with the Rider on the Many-Headed Beast had come out slugging. From the point of view of a runaway traingirl lashed to the bottom of a limping airship-basilica somewhere over central Canton Banninger, God looked on the ropes.
We're in big trouble, Sweetness thought, face lit by the heat-death of falling angels. What's happening, why, who's doing it? The questions answered themselves the instant she shaped them. That man, up there, just a fistful of metres above your head. But was this the big one, the Angels and Devastation Harx, duking it out, mano a mano, or was he merely testing the limits of his powers?
Crimson strove against the lilac. Beam by beam, duel by duel, angel by angel, crimson was failing. Sweetness's carefully constructed constellations were unravelling as reinforcements were de-mothballed from centuries of cyber-sleep, powered up their altitude jets and rolled into attack orbits. Waves of crimson and lilac crashed against each other, surged back and forth across the moonring like the rather cheap rippling sand tank sculpture Uncle Mort had got, together with a dose, from that maintenance woman in Llangonedd Junction, and was meant to be relaxing but made Sweetness feel bilious. Stars fell like sparks from a wheel foundry, scattered across the nightside of the planet. It was an oddly soothing sight, war in heaven, until Sweetness realised the only reason she was not free-floating atoms in a cloud of superheated helium was because of the very weapon Devastation Harx was using to gain access to the battle systems.
He cuts down angels like grass in the city park, and you're going against him with nothing more than a stick of sunblock, the bottom of a tube of glue, two thirds of a posh frock and a half-eaten romantic novel?
He who fights the tiger has no eye for the mosquito on his neck, she reminded herself, which was like something Cadmon, or, for that matter, Uncle Neon, might have said.
Yeah, until the mosquito bites.
High in the planetary approaches, inconceivable forces marched and countermarched, outflanked and ambushed, attacked and were thrown back. The Banninger sky still burned with the corpses of angels, but the lilac assault had been halted. The western horizon was lit by hundreds of puff-ball novas, sparkling like corroboree whizz-bangs: Harx's orbital partacs, Sweetness guessed. The picket of lilac beams faltered, then failed. Crimson rushed through in ten, twenty, fifty places, invading like cancer. The lilac rallied but Devastation Harx's intervention was at an end. The lilac was forced back on itself, inward, like a black hole collapsing under its own weight. Like an imploding star, it was merely overture to explosion. A single starburst, brilliant as the sun, lit the night hemisphere. Sweetness blinked afterimages out of her eyes as the nova turned the sky white, then faded. Something big had gone up, up there. A stardock, a Skywheel transfer station; maybe an orhab. There were people on those big cylinders. No legs and four arms and way too long and snooty people because they disdained coming down to earth, but still people. They probably never even knew they were dying.
Dark night returned, darker for having been broken by unnatural light. Even to non-astronomical Sweetness Engineer, the moonring looked tattered, moth-eaten. The constellations would never be the same again. Now someone would have to think up new names for them. The man in the flying cathedral had been beaten, at permanent cost to the night sky. This time. The next war would be fought on another battlefield entirely: the shifting interplay of alternative quantum universes. Next time, reality would be the casualty.
“Oh, man!” Sweetness said, suddenly cold and small and very high up, far from her close little cubby, and alone. She drew her knees up against her chest, hugged them to her, bound them close with cable and wished for something more to look at than lights in darkness.
A third time, that dislocation of having fallen asleep without knowing. Sweetness came to herself with a gasp and shudder. No nod, no doze, this; she woke with the light of early morning full in her face. Huddled over in her web of cables, she had slept away entire cantons and quarterspheres. The sun was a spreading scab of blood on the western horizon, clotted between the continental upthrusts of the Great Volcanoes, the only hint of the terrible war that had been fought in the dark. The air was miraculously clear and bright; light flooded across the land, driving early ribbons of cloud before it like a Purging Priest a poolful of swingers. Sweetness painfully lifted her arm to shade her eyes, tried to blink the morning gold out of it. Blinded. Then the sun lifted clear from the hollow between the mountains and one of the great vistas of her solar syst
em unveiled itself to Sweetness Asiim Engineer 12th.
This little red world was never the nearest, but had always been dearest to the hearts and bones of Motherworld. Since before words, in the great songtime of the dry plain, the ancestors of humans had looked up to this the speck of blood where the needle of imagination pricked the sky and invested it with power. An angry star, the eye of a martial god, masculine, stomping and sanguine, armoured in rust. It rose and set on a million lootings, burnings, invadings and besiegings. When the gods died, the warlike aspect was transferred and made concrete in the planet itself. It hung by night, watching, while minds immeasurably superior to man's drew up plans. The world itself was our red enemy. Even its puny, pumicey moons were demonised. Fear! Terror! Our true enemy is always our neighbour. Naked to our lenses, human imagination had engineered its surface. Whether watered by slow canals, galloped across by green or red barbarians; contemplated by a wistful, autumn people; the little world next one out, unlike the other globes in the system, rocky or smothered with steam, had always possessed a geography. It had regions, landscapes, places. Names were written on its skin. To name a thing has always been to claim possession of it.
It was only when the first space vehicles went out from Motherworld that its humanity realised the long injustice they had committed. This was no war-lord, no red destroyer. Beneath the thin, cold unbreathable atmosphere—no life here, another myth dashed—and the veils of dust was the face of a woman, graceful, refined, strong and mysterious. It had good bones, the little red world.
Here, in the early space days, the ancient and persistent lie of “Motherworld” was exposed. The genders had always bent the other way. A woman must be possessed. A gentle wooing by go-betweens, then the men were sent out from the aggressive bigger blue dot to lay claim to the world next door. They drove round in their machines, put their feet on it, stuck their flags in it, made it theirs. A forced marriage of worlds. After wedding, impregnation. The barren must be made to carry life. The arrogance was monumental, the vision more than its equal. It was a big universe out there, and hostile to clever carbon. But even the technologically extended lives of the golden who controlled the home planet's immense resources were too short to measure the scale of transforming one world into another. Water gushing down the dried-up riverbeds, spring green blooming across the high plateaulands, waves breaking on the red shores of shallow blue seas: these were visions no amount of their wealth could buy them. Their engineering advisers gave them a quick, flashy, hideously pricey fix: see that great rift valley? Four and a half thousand kilometres long, five kilometres deep? Stick a glass roof over it. Turn it into one mother of a greenhouse. Better still, make it to last. Build it out of diamond. Diamond as big as the Ritz? Phah! Diamond as big as a continent. Good, hard science. Technical and manly.
Fleets of vast, visually chaotic engineering ships were sent into slow transfer orbits to the wife-world. Surface workers surveying the sites watched the thirty-kilometre units move into low orbit and disassemble themselves from their drive-spines. They dropped automated construction modules on Grand Valley day and night for seven weeks.
Pressure-dome hoovervilles mushroomed up the length of the valley floor; as the easterlies clocked off, the westerlies clocked on, new dawn on their hard helmet faceplates. Construction plants drew in megatons of carbon dioxide—all the better for the atmospheric manforming—and by the alchemy of molecular processing, spun it into engineering-grade carbon nanofibre. Diamond trees began to rise from great Mariner rift. Day by day they grew as the assemblers wove carbon; through blinding CO2 fogs, through the hurricane seasons, through the blanketing dust storms when engineers went blind even by their helmet lights and navigated by heavy sonar. Carbon on carbon, molecules locking together. One kilometre, two kilometres they rose. One and a half long years after the engineer-towns, which would one day be the great and civilised cities of the valley, struck their taproots into the cold, dead mantle, two million trunks topped the highest of the canyon mesas and budded into four branches. A forest of diamond grew in the great valley. Out on the high blasted plains, a thousand vitrification plants moved over their immaculately surveyed and levelled sites, fusing silicon sand to trace-doped glass hexagons five hundred metres across. Flotillas of robot aerobodies cautiously shifted the panes into position; even in lower gravity, one warp could have thrown the tensile integrity of an entire canton. They settled on to their bolt-posts; one by one the nuts were tightened while scuttling groutbots filled the gaps with light-permeable expansion mastic. By scabs and scars, like some archaic children's game of territory and capture, a tessellation of hexagons spread across the canyonlands of Grand Valley. Twenty long-years after the first gaffers had surveyed their sites and threw up their Carbonbergs, the last constructor units disassembled, reconfigured into maintenance mode and buried themselves in the regolith.
As one pundit put it, Grand Valley now ran to thirty trillion carats.
Even as the last roofplates were being bolted into place, a new and noble guild was receiving its letters patent; a nation as individual and caste-ridden as the trainfolk: the Ancient and Pristine Order of Windowcleaners. Only when the glass was spotless, utterly transparent to every spectrum of light, could the ecological engineers be moved in. Nothing Pristine about this order. A grubby crew, these, soily-handed, humusy, stained and muddied. Dirty knees on their pressure suits. It is a work of years to make a soil, yet more to weave an atmosphere, decades longer for a mix of gases to become a self-perpetuating, self-regulating and adjusting homoeostatic system that some people think of as a planetary organism and call Gaia, except that here it was Gaia-in-a-bottle, and needed a different name altogether.
The grunt engineering had been the easy bit. The golden rich fretted long decades—twice as unendurable as those of their homeworld—for the day when the first of the ecoengineers undogged her helmet, lifted it off, took a long, deep breath and found it very good. Few remained of that impatient generation; the last twenty lived out their days in canyonside adobes hunting in pristine parklands under diamond skies. A great oasis, sheltered from the scoring winds and terrifying energies of ROTECH's larger scale manforming, green on red like a colour blindness test for an entire planet. A strip development that reached round one third of a world. When sunrising and sunsetting flashed from the roof glass tiles, they heliographed across interplanetary space. Watchers on nightside Motherworld would wink and blink the novadazzle out of their eyes. Within their roofed-in world, the ancient rich, spry in the low gravity, observed their night sky fill up with stars: the vanguard of the new generation of planetary engineers seeding themselves across the parking orbits. A scary people, this; less patient even than the greenhouse gardeners, their angel-machines would engineer realities wholesale.
Selah. So be it. Around here, this history began to abut into another Sweetness had recently heard and little more need be said of it, save that beneath the great glass roof, the last of the golden died and their sculpted mesa-chateaux became the cores of the elegant and diverse cities of Grand Valley, a patchwork of four hundred cantonettes and city-states and the densest and most diverse cultural region in the solar system. And that it was the dawn glory of Worldroof that so amazed Sweetness Asiim Engineer, left hanging in her precarious web.
With a wan, early mist clinging to the roof panels, Sweetness first thought of ice mornings on the winter transpolar runs, when the temperatures high high north dropped so low the carbon dioxide smoked out of the atmosphere into a thin rime. Then, as the sun gained in strength and the mist burned off, she imagined that she was flying over the board of a titanic children's game, a thing she had once hallucinated when she went down with one of those necessary childhood diseases and her temperature hit the high thirties. Vast playing pieces should be moving from hexagon to hexagon, manoeuvring and threatening. Shading her eyes, she could discern distant dark shapes standing out above the fields of hexes, stalky and angular: mooring towers for Skywheel ground-to-orbit shuttles, commun
ications masts, but her imagination made them Peons and Palisers and Prelates investing and humiliating Princes and Palaces. She reminded herself she had had very little sleep last night, and she had witnessed a fragment of Armageddon, so powers and dominions were lodged in her head. The light was still low and glancing enough to render the glass opaque, a golden highway over which the flying cathedral drifted. Half a degree of altitude, and on an instant, the ground beneath her feet went transparent. She thought of clouds lifting or some inky solution in a School of the Air chemistry demonstration clearing with a drop of reagent. Sweetness's was not a seafaring family—she had never set foot on a water-borne craft—but her childhood bedtimes had been filled with stories from the shallow oceans, of pirates and shipwrecks and drowned cities of the wicked, down there, where the people still went about their business in the watery streets and on clear, fearful nights, their bells could be heard, tolling from the submerged campaniles. The small, manicured farms, the geometric roads, the tightly packed villages and towns beneath her feet were the stuff of such stories. The cathedral passed over the support branch of one of the roof-trees. At its tip, it split into finer and finer branchings, suggesting a new image to Sweetness; blood vessels, capillaries: a city beneath the skin, if such a thing could be. Peering down between her feet, she saw that the upper levels of pier were encrusted with orioles and turrets and perilous balconies. Grand Valley was as familiar to her as any other piece of the planet's terrain; the vertical cities that clung to the bottom couple of kilometres of the roof-trees held no wonder for her any more, but the view from above revealed details previously hidden by perspective. On one of the very highest terraces, tiny figures celebrated some dawn party: as the airship's shadow fell over them, Sweetness thought they looked up, and that one waved. She waved back. Now she crossed the junction of two roofplates; a perfect black fault line across the outer burbs of one of the valley cities, like a knife cut in reality. A couple of minutes onward, dark scurrying machines worked doggedly at a hole punched through the tough glass: some bolide snuck through while the anti-meteor defences had been otherwise occupied in the night. They fused over the cracks, wove silica from their mandibles like spiders walling themselves up in egg-cocoons of silk. Sweetness noticed that they were working on both sides of the wound; the ones beneath clung nonchalantly with suckered feet.
