Sylveste was reminded that it was fighting a constant battle with the crustal defences of Cerberus, and that he should not count blindly on its protection. If it failed, he knew, it would be consumed in hours; the wound in the crust would close, and with it his escape route.
‘It is necessary to replenish reaction mass,’ the suit said.
‘What?’
Sajaki spoke for the first time since they had left the ship. ‘We used a lot of mass getting here, Dan. We need to top up before we enter hostile territory.’
‘Where from?’
‘Look around you. There’s an awful lot of reaction mass waiting to be used.’
Of course; there was nothing to stop them drawing resources from the bridgehead itself. He agreed, doing nothing while Sajaki took control of his suit. One of the steep, incurving walls loomed nearer, dense with ornate extrusions and random clusters of machinery. The scale of the thing was overwhelming now; like a dam wall which curved round until its ends met. Somewhere in that wall, he thought, were the bodies of Alicia and her fellow mutineers…
There was enough sense of gravity to engender a strong sense of vertigo, not aided by the way the bridgehead narrowed below, which made it seem like an infinitely deep shaft. The best part of a kilometre away, the star-shaped speck of Sajaki’s suit had made contact with the precipitous wall on the far side. A few moments later Sylveste touched a narrow ledge, one that jutted no more than a metre beyond the wall. His feet made soft contact and suddenly he was poised there, ready to topple back into the nothingness behind him.
‘What do I have to do?’
‘Nothing,’ Sajaki said. ‘Your suit knows exactly what to do. I suggest you start trusting it: it’s all that’s keeping you alive.’
‘Is that meant to reassure me?’
‘Do you think reassurance would be especially appropriate at this point? You’re about to enter one of the most alien environments that any human has ever known. I think the last thing you need is reassurance.’
While Sylveste watched, a trunk extruded from the suit’s chest until it made contact with a section of the bridgehead’s wall material. A few seconds later it began to pulse, bulges squirming along its length, back into the suit.
‘Vile,’ Sylveste said.
‘It’s digesting heavy elements from the bridgehead,’ Sajaki said. ‘The bridgehead gives of itself freely, since it recognises the suit as being friendly.’
‘What if we run out of power inside Cerberus?’
‘You’ll be dead long before running out of power becomes a problem to your suit. But it needs to replenish reaction mass for its thrusters. It has all the energy it needs, but it still requires atoms to accelerate.’
‘I’m not sure I like that last bit; about being dead.’
‘It isn’t too late to return.’
Testing me, Sylveste thought. For a moment he considered it rationally, but only for a moment. He was scared, yes — more so than he could comfortably remember; even if he went back to Lascaille’s Shroud. But, as then, he knew that the only way to punch through his fear was to push on. To confront whatever it was that led to that fear. But, when the refuelling process was complete, it took all the nerve in the world to step off the ledge and continue the descent into the emptiness enclosed by the bridgehead.
They sank lower, dropping for long seconds before checking their fall with brief squirts of thrust. Sajaki was beginning to allow Sylveste some voluntary control of his suit now; slowly decreasing the suit’s autonomic dominance until Sylveste was controlling most of it himself; the transition was barely noticeable. They were descending now at a rate of thirty metres per second, but it seemed to quicken as the walls of the funnel came closer together. Now Sajaki was only a few hundred metres away, but the facelessness of his suit offered little sense of human presence, no sense of companionship. Sylveste still felt dreadfully alone. And with good reason, he thought — it was possible that no thinking creature had been this close to Cerberus since it was last visited by the Amarantin. What ghosts had festered here in the intervening thousand centuries?
‘Approaching the final injection tube,’ Sajaki said.
The conic walls constricted now to a diameter of only thirty metres, then plunged vertically into darkness, as far as the eye could see. His suit veered towards the midline of the approaching hole without his bidding; Sajaki’s suit lagged slightly behind.
‘I wouldn’t deny you the honour of being first in,’ said the Triumvir. ‘You’ve waited for it long enough, after all.’
They were in the shaft. Sensing their arrival, the walls lit up with recessed red lights. The impression of vertical speed was huge now, and more than a little sickening; too much like being injected down a syringe. Sylveste remembered the time when Calvin had shown him the passage of an endoscope through one of his patients; the ancient surgical tool with a camera eye at one end of its coiled length. He remembered the headlong rush along an artery. He remembered the night flight to Cuvier after he had been arrested at the obelisk excavation, streaking through canyons towards his political nemesis. He wondered if there had ever been a time in his life when he was certain of what lay at the end of those rushing walls.
Then the shaft vanished and they were dropping through emptiness.
Volyova reached the hangar chamber, pausing at one of the observation windows to check that the shuttles really were accounted for, and that the data she had seen on her bracelet had not been manipulated by Sun Stealer. The plasma-winged transatmospheric ships were still there, clamped in their holding pens like rows of arrowheads in a fletcher’s workshop. She could begin powering one of them now, via the bracelet, but that was too dangerous, too likely to draw Sun Stealer’s attention and alert him to what she was planning. At the moment she was safe enough, since she had not entered a part of the ship where Sun Stealer’s senses could penetrate. At least, she hoped not.
She could not simply stroll aboard any of the shuttles. The usual access routes would take her through parts of the ship she did not dare enter; places where servitors had free range and janitor-rats were in direct biochemical consort with Sun Stealer. She had only one weapon now: the needler. She had left Khouri with the slug-gun, and while she did not doubt her proficiency, there were limits to what could be achieved by mere skill and determination. Especially as the ship would by now have had time to synthesise armed drones.
So now she found her way to an airlock chamber; not one which led to outside space, but one which accessed the depressurised vault of the hangar. The chamber was knee-deep in effluent, and all its lighting and heating systems had failed. Good. No chance then of Sun Stealer being able to watch her remotely, or even know she was there. She opened a locker and was relieved to find that the lightweight suit it was meant to contain was still present, and that it had not been visibly damaged by exposure to ship-slime. It was less bulky than the kind of suit Sylveste would have taken; less intelligent too, with no servosystems or integral propulsion. Before donning the suit she recited a series of words — well rehearsed — into her bracelet, and then arranged the bracelet to respond to vocal commands spoken into her communicator, rather than via its own acoustic sensors. Then she had to latch on a thruster backpack, taking a moment to stare intently at its controls, as if knowledge of how to use it would bubble up from her memory by sheer force of will. She decided that the basics would come back to her as soon as she required them, and carefully stowed the needler on the suit’s external equipment belt. She exited without fuss, jetting into the hangar, using a small constant thrust level to prevent herself drifting down the chamber. No part of the ship was in freefall, since the ship itself was not orbiting Cerberus, but holding itself artificially fixed in space, a tiny drain on the power of its engines.
She selected the shuttle she would use; the spherical
Hit, both machines began to drift down the hangar, bleeding smoke.
She thumbed the backpack controls, imploring it to push her faster. The
