"What if they were?" Horza took another look at the holo display of the GSV's internal layout. He briefly magnified the volume around Smallbay 27492 before switching the repeater screen off. The drone was silent for a second, then backed off through the doorway.
"Great. I'm locked in an antique with a paranoid lunatic. I think I'll go and look for somewhere safer than this."
"You do that!" Horza yelled down the corridor after it. He turned the hangar circuit back on. "Aviger?" he said.
"I've done it," said the old man's voice.
"Right. Get to the mess fast and strap in." Horza killed the circuit again.
"Well," Wubslin said, sitting back in his seat and scratching his head, looking at the bank of screens in front of him with their arrays of figures and graphs, "I don't know what it is you're intending to do, Kraiklyn, but whatever it is, we're as ready as we'll ever be to do it." The stout engineer looked across at Horza, lifted himself slightly from his seat and pulled the restraining straps over his body. Horza grinned at him, trying to look confident. His own seat's restrainers were a little more sophisticated, and he just had to throw a switch for cushioned arms to swing over and inertia fields to come on. He pulled his helmet over his head from the hinged position and heard it hiss shut.
"Oh my God," Wubslin said, looking slowly away from Horza to stare at the almost featureless rear wall of the Smallbay shown on the main screen. "I sure as hell hope you're not going to do what I think you are.
Horza didn't reply. He hit the button to talk to the mess. "All right?"
"Just about, Kraiklyn, but-" Yalson said. Horza killed that circuit, too. He licked his lips, took the controls in his gloved hands, sucked in a deep breath, then flicked the thumb buttons on the CAT's three fusion motors. Just before the noise started he heard Wubslin say:
"Oh, my God, you are-"
The screen flashed, went dark, then flashed again. The view of the Smallbay's rear wall was lit by three jets of plasma bursting from underneath the ship. A noise like thunder filled the bridge and reverberated through the whole craft. The two outboard motors were the main thrust, vectored down for the moment; they blasted fire onto the deck of the Smallbay, scattering the machinery and equipment from underneath and around the craft, slamming it into walls and off the roof as the blinding jets of flame steadied under the vessel. The inboard, lift-only nose motor fired raggedly at first, then settled quickly, starting to burn its own hole through the thin layer of ultradense material which covered the Smallbay floor. The Clear Air Turbulence stirred like a waking animal, groaning and creaking and shifting its weight. On the screen, a huge shadow veered across the wall and the roof in front as the infernal light from the nose fusion motor burned under the ship; rolling clouds of gas from burning machinery were starting to haze over the view. Horza was amazed that the walls of the Smallbay had held out. He flicked the bow laser at the same time as increasing the fusion motor power.
The screen detonated with light. The wall ahead burst open like a flower seen in time lapse, huge petals throwing themselves towards the ship and a million pieces of wreckage and debris flashing past the vessel's nose on the shock wave of air bursting in from the far side of the lasered wall. At the same time, the Clear Air Turbulence lifted off. The leg-weight readouts stopped at zero, then blanked out as the legs, glowing red with heat, stowed themselves inside the hull. Emergency undercarriage cooling circuits whined into action. The craft started to slew to one side, shaking with its own power and with the impact of debris swirling about it. The view ahead cleared.
Horza steadied the ship, then gunned the rear motors, flinging some of their power backwards, towards the Smallbay doors. A rear screen showed them glowing white hot. Horza would dearly have liked to head that way, but reversing and ramming the doors with the CAT would have probably been suicidal, and turning the craft in such a confined space impossible. Just going forward was going to be hard enough…
The hole wasn't big enough. Horza saw it coming towards him and knew straight away. He used one shaking finger on the laser beam-spread control set in the semi-wheel of the controls, turning the spread up to maximum then firing once more. The screen washed out with light again, all around the perimeter of the hole. The CAT stuck its nose and then its body into another Smallbay. Horza waited for something to hit the sides or roof of the white-hot gap, but nothing happened; they sailed through on their three pillars of fire, throwing light and wreckage and waves of smoke and gas before them. The dark waves blasted out over shuttles; the whole Smallbay they were now moving slowly through was full of shuttles of every shape and description. They were floating over them, battering them and melting them with their fire.
Horza was aware of Wubslin sitting on the seat beside him, his eyes locked onto the view ahead, his legs drawn up as far as possible so that his knees stuck up above the edge of the console, and his arms locked in a sort of square over his head, each hand grasping the bicep of the other arm. His face was a mask of fear and incredulity when Horza turned round to glance at him, and grinned. Wubslin pointed frenziedly at the main screen. "Watch!" he shrieked over the racket.
The CAT was shaking and bouncing, rocked by the stream of superheated matter pouring from under its hull. It would be using the atmosphere around it to produce plasma, now that there was air available, and in the relatively confined space of the Smallbays the turbulence created was enough to shake the vessel bodily.
There was another wall ahead, coming up faster than Horza would have liked. They were slewing slightly again as well; he narrowed the laser angle again and fired, pulling the ship round at the same time. The wall flashed once around its edges; the roof and floor of the Smallbay flashed in loops of flame where the laser caught them, and dozens of parked shuttles ahead of them pulsed with light and heat.
The wall ahead started to fall slowly back, but the CAT was coming up on it faster than it was crumpling. Horza gasped and tried to pull back; he heard Wubslin howl, as the vessel's nose hit the undamaged centre of the wall. The view on the main screen tilted as the ship rammed into the wall material. Then the nose came down, the Clear Air Turbulence quivered like an animal shaking water from its fur, and they were rocking and yawing into yet another Smallbay. It was totally empty. Horza gunned the engines a little more, took a couple of bursts with the laser at the next wall, then watched in amazement as this wall, instead of falling back like the last one, crashed down towards them like a vast castle drawbridge, slamming in one fiery piece onto the deck of the empty Smallbay. In a fury of steam and gas, a mountain of water appeared over the top of the collapsing wall and poured out in a huge wave towards the approaching ship.
Horza heard himself shouting. He rammed the motor controls full on and kept the laser fire button hard down.
The CAT leapt forward. It flashed over the surface of the cascading water, enough of the plasma heat smashing into its liquid surface to instantly fill all the space of Smallbays its passage had created with a boiling fog of steam. As the tide of water continued to pour from the flooded Smallbay and the CAT screeched above it, the air about the ship filled with superheated steam. The external pressure gauge went up too quickly for the eye to follow; the laser blasted even more vapour off the water in front, and with an explosion like the end of the world the next wall blew out ahead of the vessel — weakened by the laser and finally blasted away by the sheer pressure of steam. The Clear Air Turbulence shot out from the tunnel of linked Smallbays like a bullet from a gun.
Motors flaming, in the middle of a cloud of gas and steam which it quickly outdistanced, it roared into a canyon of air-filled space between towering walls of bay doors and opened accommodation sections, lighting up kilometres of wall and cloud, screaming with its three flame-filled throats, and seemingly pulling after it a tidal wave of water and a volcano-like cloud of steam, gas and smoke. The water fell, turning from a solid wave into something like heavy surf, then spray, then just rain and water vapour, following the huge flapping card of the bay doo
r tumbling through the air. The CAT wrenched itself round, twisting and slewing through the air in an attempt to check its headlong rush towards the far wall of Smallbay doors facing it across that vast internal canyon. Then its motors flickered and went out. The Clear Air Turbulence started to fall.
Horza gunned the controls, but the fusion motors were dead. The screen showed the wall of doors to other bays on one side, then air and clouds, then the wall of bay doors on the other side. They were in a spin. Horza looked over at Wubslin as he fought with the controls. The engineer was staring at the main screen with a glazed expression on his face. "Wubslin!" Horza screamed. The fusion motors stayed dead-
"Aaah!" Wubslin seemed to have woken up to the fact that they were falling out of control; he leapt at the controls in front of him. "Just fly it!" he shouted. "I'll try the primers! Must have over-pressured the motors!"
Horza wrestled with the controls while Wubslin tried to restart the engines. On the screen, walls spun crazily about them and clouds beneath them were coming up fast — beneath them; really beneath them; a dead flat layer of clouds. Horza shook the controls again.
The nose motor burst into life, guttering wildly, sending the spinning craft careering off towards one side of the artificial cliff of bay doors and walls. Horza cut the motor out. He steered into the spin, using the craft's control surfaces rather than the motors, then he aimed the whole ship straight down and put his fingers on the laser buttons again. The clouds flashed up to meet the vessel. He closed his eyes and squeezed the laser controls.
The Ends of Invention was so huge it was built on three almost totally separate levels, each over three kilometres deep. They were pressure levels, there because otherwise the differential between the very bottom and the very top of the giant ship would have been the difference between standard sea level and a mountain top somewhere in the tropopause. As it was, there existed a three and a half thousand metre difference between the base and roof of each pressure level, making sudden journeys by traveltube from one to the other inadvisable. In the immense open cave that was the hollow centre of the GSV the pressure levels were marked by force fields, not anything material, so that craft could pass from one level to another without having to go outside the vessel, and it was towards one of those boundaries, marked by cloud, that the Clear Air Turbulence was falling.
Firing the laser did no good whatsoever, though Horza didn't know that at the time. It was a Vavatch computer, which had taken over the internal monitoring and control from the Culture's own Minds, which opened a hole in the force field to let the falling vessel through. It did so in the mistaken assumption that less damage would be caused to The Ends of Invention by letting the rogue vessel fall through than having it impact.
In the centre of a sudden maelstrom of air and cloud, in its own small hurricane, the CAT burst through from the thick air at the bottom of one pressure level and into the thin atmosphere at the top of the one below. A vortex of rag-clouded air blew out after it like an inverted explosion. Horza opened his eyes again and saw with relief the distant floor of the GSV's cavernous interior, and the climbing figures on the main fusion motors" monitor screens. He hit the engine throttles again, this time leaving the nose motor alone. The two main engines caught, shoving Horza back in his seat against the cloying hold of the restrainer fields. He pulled the nose of the diving craft up, watching the floor far below gradually disappear from view as it was replaced by the sight of another wall of opened bay doors. The doors were much larger than those of the Smallbays in the level they had just left, and the few craft Horza could see either nosing into or appearing out of the lit lengths of the huge hangars were full-size starships.
Horza watched the screen, piloting the Clear Air Turbulence exactly like an aircraft. They were travelling quickly along a vast corridor over a kilometre across, with the layer of clouds about fifteen hundred metres above them. Starships were moving slowly through the same space, a few on their own AG fields, most towed by light lifter tugs. Everything else was moving slowly and without a fuss; only the CAT disturbed the calm of the giant ship's interior, screaming through the air on twin swords of brilliant flame pulsing from white-hot plasma chambers. Another cliff-face of huge hangar doors faced them. Horza looked about him at the curve of main screen and pulled the CAT over on a long banking left turn, diving a little at the same time to head down an even broader canyon of space. They flashed over a slow-moving clipper being towed towards a distant open Mainbay, rocking the starship in their wake of superheated air. The wall of doors and opened entrances slanted towards them as Horza tightened the turn. Ahead, Horza could see what looked like a cloud of insects: hundreds of tiny black specks floating in the air.
Far beyond them, maybe five or six kilometres away, a thousand metre square of blackness, bordered with a slowly flashing strip of subdued white light, was the exit from The Ends of Invention. It was a straight run.
Horza sighed and felt his whole body relax. Unless they were intercepted, they had done it. With a little luck now, they might even get away from the Orbital itself. He gunned the engines, heading for the inky square in the distance.
Wubslin suddenly sat forward, against the pull of acceleration, and punched some buttons. His repeater screen set in the console magnified the centre section of the main screen, showing the view ahead. "They're people!" he shouted.
Horza frowned over at the man. "What?"
"People! Those are people! They must be in AG harnesses! We're going to go right through them!"
Horza looked briefly over at Wubslin's repeater screen. It was true; the black cloud which almost filled the screen was made up of humans, flying slowly about in suits or ordinary clothes. There were thousands of them, Horza saw, less than a kilometre ahead, and closing quickly. Wubslin was staring at the screen, waving his hand at the people. "Get out the way! Get out the way!" he was shouting.
Horza couldn't see a way round, over or beneath the mass of flying people. Whether they were playing some curious mass aerial game or were just enjoying themselves, they were too many, too close, too widespread. "Shit!" Horza said. He got ready to cut the rear plasma motors before the Clear Air Turbulence went into the cloud of humans. With luck they might make it through before they had to relight them, and so not incinerate too many people.
"No!" Wubslin screamed. He threw the restraining straps off, leapt across towards Horza and dived at the controls. Horza tried to fend the bulky engineer off, but failed. The controls were wrenched from his hands, and the view on the main screen tipped and swirled, pointing the nose of the speeding ship away from the black square of the GSV exit, away from the huge cloud of airborne people, and towards the cliff of brightly lit Mainbay entrances. Horza clouted Wubslin across the head with his arm, sending the man falling to the floor, stunned. He grabbed the controls back from the relaxing fingers of the engineer, but it was too late to turn away. Horza steadied and aimed. The Clear Air Turbulence darted for an open Mainbay; it flashed through the open entrance and swept over the skeleton of a starship being rebuilt in the bay, the light from the CAT's motors starting fires, singeing hair, smouldering clothes and blinding unprotected eyes.
Horza saw Wubslin lying unconscious on the floor out of the corner of his eye, rocking gently as the CAT careered through the half kilometre length of Mainbay. The doors to the next bay were open, and the next and the next. They were flying through a two kilometre tunnel, racing over the repair and docking facilities of one of Evanauth's displaced shipbuilders. Horza didn't know what was at the far end, but he could see that before they got there they would have to fly over the top of a large spaceship which almost filled the third bay along. Horza vectored the fusion fire ahead so that they started to slow. Twin beams of fire flashed on either side of the main screen as the fusion power kicked forward. Wubslin's unrestrained body slid forward on the floor of the bridge, wedging under the console and his own seat. Horza lifted the CAT's nose as the blunt snout of the parked spacecraft sitting in the bay ahead appr
oached.
The Clear Air Turbulence zoomed towards the ceiling of the Mainbay, flashed between it and the top surface of the ship, then fell on the other side and, although still slowing, shot through the final Mainbay and into another corridor of free air space. It was too narrow. Horza dived the craft again, saw the floor coming up and fired the lasers. The CAT burst through a rising cloud of glowing wreckage, bumping and shaking, Wubslin's squat frame sliding out from under the console and floating back up towards the rear door of the bridge.
At first Horza thought they were out at last, but they weren't; they were in what the Culture called a General bay.
The CAT fell once more, then levelled out again. It was in a space which seemed even larger than the main interior of the GSV. It was flying through the bay they had stored the Megaship in: the same Megaship Horza had seen on the screen earlier being lifted out of the water by a hundred or so ancient Culture lifter craft.
Horza had time to look around. There was plenty of space, lots of room and time. The Megaship lay on the floor of the giant bay, looking for all the world like a small city sitting on a great slab of metal. The Clear Air Turbulence flew past the stern of the Megaship, past tunnels full of propeller blades tens of metres across, round the side of its rearmost outrigger, where beached pleasure craft waited for a return to water, over the towers and spires of its superstructure, then out over its bows. Horza looked forward. The doors, if they were doors, of the General bay faced him, two kilometres away. They were that same distance from top to bottom, and twice that across. Horza shrugged and checked the laser again. He was becoming, he realised, almost blasé about the whole thing. What the hell? he thought.
The lasers picked a hole in the wall of material ahead, punching a slowly widening gap which Horza aimed straight for. A vortex of swirling air was starting to form around the hole; as the CAT rushed closer, it was caught in a small horizontal cyclone of air and started to twist. Then it was through, and in space.
