It hadn't been rage that made Tate destroy the equipment; it had been fear. Kearney ran into the street without looking back.

SEVENTEEN

The Lost Entradas

Human beings, hooked by the mystery of the Kefahuchi Tract, arrived on its doorstep two hundred years after they got into space.

They were arrant newcomers, driven by the nouveau enthusiasms of a cowboy economy. They had no idea what they had come for, or how to get it: they only knew they would. They had no idea how to comport themselves. They sensed there was money to be made. They dived right in. They started wars. They stunned into passivity five of the alien races they found in possession of the galaxy and fought the sixth -- which they called 'the Nastic' out of a mistranslation of the Nastic's word for 'space'-to a wary truce. After that they fought one another.

Behind all this bad behaviour was an insecurity magnificent in scope, metaphysical in nature. Space was big, and the boys from Earth were awed despite themselves by the things they found there: but worse, their science was in a mess. Every race they met on their way through the Core had a star drive based on a different theory. All those theories worked, even when they ruled out one another's basic assumptions. You could travel between the stars, it began to seem, by assuming anything. If your theory gave you a foamy space to work with -if you had to catch a wave-that didn't preclude some other engine, running on a perfectly smooth Einsteinian surface, from surfing the same tranche of empty space. It was even possible to build drives on the basis of superstring-style theories, which, despite their promise four hundred years ago had never really worked at all.

It was affronting to discover that. So when they fetched up on the edge of the Tract, looked it in the eye, and began to despatch their doomed entradas, the Earthlings were hoping to find, among other things, some answers. They wondered why the universe, which seemed so harsh on top, was underneath so pliable. Anything worked. Wherever you looked, you found. They were hoping to find out why. And while the entradistas were dying in ways no one could imagine, crushed, fried, expanded or reduced to mists of particles by the Tract itself, lesser hearts took with enthusiasm to the Beach, where they found Radio Bay. They found new technologies. They found the remains of ancient races, which they ragged about like bull terrier pups with an old bone.

They found artificial suns.

There had been, some time in the deep past, such a premium on the space closest to the Tract that there were more artificial suns in the Radio Bay cluster than natural ones. Some had been towed in from other locations; others had been built from scratch, in situ. Planets had been steered into place around them, and inserted into unnatural orbits designed to keep the Tract in maximum view. Ferociously goosed magnetic fields and ramped-up atmospheres protected them from radiation. Between the planets, under the sleets of raging light, rogue moons wove their way, in fantastically complex orbits.

These were less star systems than beacons, less beacons than laboratories, and less laboratories than experiments in themselves: enormous detectors designed to react to the unimaginable forces pouring out of the uncontained singularity hypothetically present at the centre of the Tract.

This object was massively energetic. It was surrounded by gas clouds heated to 50,000 degrees Kelvin. It was pumping out jets and spumes of stuff both baryonic and non-baryonic. Its gravitational effects could be detected, if faintly, at the Core. It was, as one commentator put it: 'A place that had already been old by the time the first great quasars began to burn across the early universe in the unimaginable dark.' Whatever it was, it had turned the Tract around it into a region of black holes, huge natural accelerators and junk matter-a broth of space, time, and heaving event horizons; an unpredictable ocean of radiant energy, of deep light. Anything could happen there, where natural law, if there had ever been such a thing, was held in suspension.

None of the ancient races managed to penetrate the Tract and bring back the news; but they all had their try. They had their try at finding out. By the time human beings arrived, there were objects and artifacts up to sixty-five million years old hanging off the edge, some clearly left by cultures many orders stranger or more intelligent than anything you saw around today. They all came prepared with a theory. They brought a new geometry, a new ship, a new method. Every day they launched themselves into the fire, and turned to cinders.

They launched themselves from places like Redline.

Whoever built Redline, whoever built its actinic, enraged-looking sun, wasn't even broadly human. Added to which a peculiar orbital motion, designed to keep the artefact at its south pole presented to a location deep inside the central area of the Kefahuchi Tract, gave it nauseous, undependable rhythms. On Redline, spring arrived twice in five years, then for a whole year in the next twenty; then every other day. When it came it was the colour and quality of cheap neon. Steaming radio-jungles and blue-lit, UV-scoured deserts precluded much in the way of direct dealing by human beings. (Though, in a broad metaphor of the exploration of the Bay itself, the brave, the unlucky and the morally dyslexic still despatched themselves on hasty half-planned entradas. In search of what? Who knew. They were quickly lost in the mists among the foetid ruins. Those that returned, having cracked their faceplates better to examine what they found, would brag around the Motel Splendido spaceport bars for a week or two on their return, then die in the tradition of the entrada, from indescribable diseases.)

Seria Mau consulted her fakebooks. 'The South Polar Artefact,' they informed her, 'resists analysis, though it appears to be a receiver rather than a transmitter.' And later: 'While "day" and "night" can be said to occur on Redline, their occurrence does not seem to be determined simply.' This was the place that lay below her, so pure and unambiguous it was a joy to behold. Also, her fate, at least in a sense. She opened a line.

'Billy Anker,' she said. 'I'm here to see you.'

After some time a voice replied, patched and faint, bracketed by static. 'You want to come down?' it said. Immediately she was nervous.

'I'll send a fetch,' she temporised.

Billy Anker had a thin stubbly face, from which the dark hair swept back into a brutal little ponytail freighted with grey. His age was uncertain, his skin darkened by the light of a thousand suns. His eyes were greeny-grey, set in deep sockets: if he liked you they considered you for some time, often becoming warmly amused; if he didn't, they slid away. They delivered nothing. Billy Anker had an enthusiasm to be out there in the Bay (some said he was born there, but what did they know? They were junkie entradistas and particle-jockeys whose soft voices, wrecked by Carmody bourbon laced with the ribosomes of local bats, told only their own romantic inner legend) always searching for something. He had no patience with anyone who didn't feel the same. Or who at least didn't feel something.

'We're here to look,' he'd say, 'and be amazed. We're not here long. Look at this. See that? Look!'

He was a thin, active, seeking little man, skin and tendons, who at all times wore the bottom half of an ancient air-pilot's G-suit, two leather coats, a red and green do-rag tied in a fanciful knot. He lost two fingers of one hand in a bad landing on Sigma End, on the edge of the accretion disc of the notorious black hole they called Radio RX-1 (nearby was the entrance to an artificial wormholewhich, he believed at the time, had its eye on the same target as the Redline South Polar Artefact). These he never had replaced.
