Consider Phlebas

"Where is it coming from? Quickly!"

"Everywhere!" Horza yelled, glancing all round the control area. "From near your eye… under the seats, over the screens, under the screens… I can't see…!"

"Go on! I can smell smoke, too, now!"

Horza looked at the slight smudge of grey filtering into the control area from the spluttering fire in the short corridor where he had shot the craft. "It's… coming from those places, and those info screens on either side of the end seats, and… just above the seats, on the side walls where that bit juts out-"

"What?" screamed the shuttle brain. "On the left facing forward?"

"Yes!"

"Put that one out first!" the shuttle screeched.

Horza dropped the extinguisher and gripped the gun in both hands again, aiming it at the bulge in the wall over the left-hand seat. He pulled the trigger: once, twice, three times. The gun blasted, shaking his whole body; sparks and bits of flying debris flew from the holes the bullets were smashing in the casing of the machine.

"EEEeee…" said the shuttle, then there was silence.

Some smoke rose from the bulge and it joined with that coming from the corridor to form a thin layer under the ceiling. Horza let the gun down slowly, looking around and listening.

"Mug," he said.

He used the hand-held extinguisher to put out the small fires in the wall of the corridor and where the shuttle's brain had been, then he went out into the passenger area to sit near the open doors while the smoke and the fumes cleared. He couldn't see any Eaters on the sand or in the forest, and the canoes were out of sight, too. He looked for some door controls and found them; the doors closed with a hiss, and Horza gri

He went back to the control area and started punching buttons and opening sections of panelling until he got some life from the screens. They all suddenly blinked on while he was fiddling with some buttons on the arm of one of the couch-like seats. The noise of surf in the flight deck made him think the doors had opened again, but it was only some external microphones relaying the noise from outside. Screens flickered and lit up with figures and lines, and flaps opened in front of the seats; control wheels and levers sighed out smoothly and clicked into place, just ready to be held and used. Feeling happier than he had been in many days, Horza started an eventually successful but longer and more frustrating search for some food; he was very hungry.

Some small insects were ru

The little insects started by eating the deep-set eyes, which were open. They hardly noticed as the shuttle rose, wobbling, into the air, picked up speed and turned inelegantly above the mountain, then roared off, through the early evening air, away from the island.

Interlude in darkness

The Mind had an image to illustrate its information capacity. It liked to imagine the contents of its memory store written out on cards; little slips of paper with tiny writing on them, big enough for a human to read. If the characters were a couple of millimetres tall and the paper about ten centimetres square and written on both sides, then ten thousand characters could be squeezed onto each card. In a metre long drawer of such cards maybe one thousand of them — ten million pieces of information — could be stored. In a small room a few metres square, with a corridor in the middle just wide enough to pull a tray out into, you could keep perhaps a thousand trays arranged in close-packed cabinets: ten billion characters in all.

A square kilometre of these cramped cells might contain as many as one hundred thousand rooms; a thousand such floors would produce a building two thousand metres tall with a hundred million rooms. If you kept building those squat towers, squeezed hard up against each other until they entirely covered the surface of a largish standard-G world — maybe a billion square kilometres — you would have a planet with one trillion square kilometres of floor space, one hundred quadrillion paper-stuffed rooms, thirty light-years of corridors and a number of potential stored characters sufficiently large to boggle just about anybody's mind.

In base 10 that number would be a 1 followed by twenty-seven zeros, and even that vast figure was only a fraction of the capacity of the Mind. To match it you would need a thousand such worlds; systems of them, a clusterful of information-packed globes… and that vast capacity was physically contained within a space smaller than a single one of those tiny rooms, inside the Mind…

In darkness the Mind waited.

It had counted how long it had waited so far; it had tried to estimate how long it would have to wait in the future. It knew to the smallest imaginable fraction of a second how long it had been in the tu

It had explored the Command System tu

And all of it was at once boring and frighteningly depressing. The level of technology possessed by the builders of the Command System was very limited indeed; everything in the tu

There was something too about the inexactitude of it all that the Mind found almost frightening. It could look at some carefully machined piece of metal or some delicately moulded bit of plastic, and know that to the people who had built the Command System — to their eyes — these things were exact and precise, constructed to fine tolerances with dead straight lines, perfect edges, smooth surfaces, immaculate right angles… and so on. But the Mind, even with its damaged sensors, could see the rough edges, the crudity of the parts and the components involved. They had been good enough for the people at the time, and no doubt they had fulfilled the most important criterion of all; they worked…

But they were crude, clumsy, imperfectly designed and manufactured. For some reason the Mind found this worrying.

And it would have to use this ancient, crude, shop-soiled technology. It would have to co
