Redemption Ark

by Alastair Reynolds

  All stars already sang to themselves. The outer layers of every star rang constantly at a multitude of frequencies, like an eternally chiming bell. The great seismic modes tracked oscillations that plunged deep into the star, down to the caustic surface just above its fusing core. Those oscillations were modest in a star of dwarf type, like Delta Pavonis. But the singer tuned itself to them, swinging around the star in its equatorial rotation frame, pumping gravitational energy into the star at precisely the right resonant frequencies to enhance the oscillations. The singer was what the mammals would have called a graver, a gravitational laser.

  In the heart of the singer a microscopic closed cosmic string, a tiny relic of the rapidly cooling early universe, had been tugged out of the seething foam of the quantum vacuum. The string was barely a scratch compared with the largest cosmic flaws, but it would suffice for the singer’s purposes. It was tugged and elongated like a loop of toffee, inflated with the same vacuum phase energy that the singer tapped for all its needs, until it had macroscopic size and macroscopic mass-energy density. Then the string was deftly knotted into a figure-of-eight configuration and plucked, generating a narrow cone of throbbing gravitational waves.

  The oscillations increased in amplitude, slowly but surely. At the same time, chirping gravitational pulses with precision and elegance, the singer sculpted the patterns themselves, causing new vibrational modes to spring into play, enhancing some and suppressing others. The star’s rotation had already destroyed any spherical symmetry in the original oscillation modes, but the modes had still been symmetric with respect to the star’s axis of spin. Yet now the singer worked to instil more profoundly asymmetric modes in the star, focusing its efforts on a single equatorial point immediately between the singer and the star’s centre of mass. It increased its power and focus, the closed cosmic string oscillating even more vigorously. Immediately below the singer, on the outer envelope of the star, mass flows were pinched and reflected, heating and compressing surface hydrogen to near-fusion conditions. Fusion did indeed erupt in three or, four concentric rings of stellar matter, but that was incidental. What mattered, what the singer intended, was that the star’s spherical envelope should begin to pucker and distort. Something like a navel was appearing in the star’s seething hot surface, an inward dimple wide enough to swallow a whole rocky world. Concentric rings of fusion, circles of searing brightness, spread out from the dimple, squalling X-rays and neutrinos into space. Still the singer continued pulsing the star with gravitational energy, the timing surgically acute, and still the dimple sank deeper, as if an invisible finger were pushing against the pliant skin of a balloon. Around the dimple the star was bulging higher into space as matter was redistributed. The matter had to go somewhere, for the singer was excavating a hole deep into the star’s interior.

  It would continue until it had reached the star’s nuclear-burning core.

  It was a fifteen-hour trip from Resurgam orbit to Nostalgia for Infinity and Khouri spent every minute of it in a state of extreme apprehension. It was not simply the strange and worrying thing that had started to happen to Delta Pavonis, although that was certainly a significant part of it. She had seen the Inhibitor weapon start its work, pointing like a great flared bugle at the surface of the star, and she had seen the star respond by growing a furious hot eye on its surface. Magnification showed the eye to be a zone of fusion, several zones, in fact, which surrounded a deepening pit in the star’s envelope. It was in the face of the star that was turned towards Resurgam, which did not seem likely to be accidental. And whatever the weapon was doing, it was doing it with astonishing speed. The weapon had taken so long to reach readiness that Khouri had mistakenly assumed that the final destruction of Delta Pavonis would take place on the same leisurely timescale. This was clearly not going to be the case. She would have been better thinking of an elaborate build-up to an execution, with many legal hurdles and delays, but which would conclude in a single bullet shot or killing surge of electrical current. That was how it was going to be with the star: a long, grave preparation followed by an extremely swift execution.

  And they had still evacuated only two thousand people — in fact, it was far worse: they had transported two thousand people from the surface of Resurgam, but none of those had yet seen Nostalgia for Infinity, or had any idea of what they were going to find when they stepped aboard it. Khouri hoped that none of her nervousness was apparent, since the passengers were volatile enough already.

  It was not simply the fact that the transfer craft was designed to take far fewer occupants, and so they were forced to endure the journey in cramped, prisonlike conditions, with the environmental systems strained to the limit just to provide sufficient air, water and refrigeration. These people were taking a tremendous risk, putting their faith in forces utterly beyond their control. The only thing holding them together was Thorn, and even Thorn appeared on the edge of nervous exhaustion. There were constant squabbles and minor crises breaking out all over the ship, and whenever they happened Thorn was there, soothing and reassuring, only to dash off somewhere else as soon as the trouble had been allayed. His charisma was being stretched butter-thin. He had not only been awake for the entire trip, but also for the day before the lift-off of the final shuttle flight and the six hours it had taken to find places for the five hundred new arrivals.

  It was taking too long; Khouri could see that. There would have to be another ninety-nine flights like this before the evacuation operation was done, ninety-nine further opportunities for all hell to break loose. It might get easier once word got back to Resurgam that there was a star ship at the end of the journey, rather than some diabolical government trap. On the other hand, when the precise nature of the starship became clearer things might get an awful lot worse. And there was every likelihood that the weapon would soon finish whatever it had initiated around Delta Pavonis. When that happened, every other problem would suddenly look very slight indeed.

  But at least they were nearly home and dry with this trip.

  The transfer ship was not designed for transatmospheric flight. She was a graceless sphere with a cluster of motors at one pole and the dimple of a flight deck at the other. The first five hundred passengers had spent many days aboard, exploring every grubby cranny of her austere interior. But at least they had had some room to spare. When the next load came up, things became a little more difficult. Food and water had to be rationed and each passenger assigned a specific cubbyhole. But it was still tolerable. Children had still been able to run around and make nuisances of themselves, and adults had still been able to find a little privacy when they needed it. Then the next shipment had come up — another five hundred — and the whole tone of the ship had changed subtly, and for the worse. Rules had to be enforced rather than politely suggested. Something very close to a miniature police state had been created aboard the ship, with a harsh scale of penalties for various crimes. So far there had been only minor infringements of the draconian new laws, but Khouri doubted that every trip would run as smoothly. Sooner or later she would probably be required to make an example of someone, for the benefit of the others.

  The final five hundred had been the greatest headache. Slotting them in had resembled a fiendish puzzle: no matter how many permutations they tried, there were always fifty people still waiting on the shuttle, glumly aware that they had been reduced to irksome surplus units in a problem that would have been a great deal more tractable had they not existed.

  And yet, finally, a way had been found to get everyone aboard. That part at least would be simpler next time, but the rule of discipline might have to be even stricter. The people could be allowed no rights aboard the transfer craft.

  Thirteen hours out, a kind of exhausted calm fell across the ship. She met Thorn by a porthole, just out of earshot of the nearest huddle of passengers. Ashen light made his face statuelike. He looked utterly dejected, sapped of any joy in what they had achieved.

  ‘We’ve done
it,’ she said. ‘No matter what happens now, we’ve saved two thousand lives.’

  ‘Have we?’ he asked, keeping his voice low.

  ‘They’re not going back to Resurgam, Thorn.’

  They spoke like business associates, avoiding physical contact. Thorn was still a ‘guest’ of the government and there must not appear to be any ulterior motive behind his co-operation. Because of that necessary distance, an act that had to be maintained at all times aboard the shuttle, she felt the urge to sleep with him more strongly than she had ever done before. She knew that they had come very close aboard the ship after the encounter with the Inhibitor cubes in Roc’s atmosphere. But they had not done it then, and nor had they when they were on Resurgam. The erotic tension that had existed between them ever since had been thrilling and painful at the same time. Her attraction to him had never been stronger, and she knew that he wanted her at least as much. It would happen, she knew. It was just a question of accepting what she had long known she had to accept, which was that one life was over and another must begin. It was about making the choice to discard her past, and accepting — forcing herself to believe — that she was not dishonouring her husband by that act of disavowal. She just hoped that wherever he was, alive or dead now, Fazil Khouri had come to the same realisation and had found the strength to close the chapter on the part of his life that had included Ana Khouri. They had been in love, desperately in love, but the universe cared nothing for the vicissitudes of the human heart. Now they both had to follow their own paths.

  Thorn touched her hand gently, the gesture hidden in the shadows that hung between them. ‘No,’ he said. ‘We’re not taking them back to Resurgam. But can we honestly say we’re taking them to a better place? What if all we’re doing is taking them to a different place to die?’

  ‘It’s a starship, Thorn.’

  ‘Yes, one which isn’t going anywhere in a hurry.’

  ‘Yet,’ she said.

  ‘I sincerely hope you’re right.’

  ‘Ilia made progress with the Captain,’ she said. ‘He began to come out of his shell. If she managed to persuade him to deploy the cache weapons, she can talk him into moving.’

  He turned from the porthole, harsh shadows emphasising his face. ‘And then?’

  ‘Another system. It doesn’t matter which one. We’ll take our pick. Anything’s got to be better than staying here, hasn’t it?’

  ‘For a while, perhaps. But shouldn’t we at least investigate what Sylveste can do for us?’

  She took her hand from his and said guardedly, ‘Sylveste? Are you serious?’

  ‘He took an interest in our affairs inside Roc. At the very least, something did. You recognised it as Sylveste, or a copy of his personality. And the object, whatever it was, returned to Hades.’

  ‘What are you suggesting?’

  ‘That we consider the unthinkable, Ana: seeking his help. You told me that the Hades matrix is older than the Inhibitors. It may be something stronger than them. That certainly appeared the case inside Roc. Shouldn’t we see what Sylveste has to say on the matter? He might not be able to help us directly, but he might have information we can use. He’s been in there for subjective aeons, and he’s had access to the archive of an entire starfaring culture.’

  ‘You don’t understand, Thorn. I thought I told you, but obviously it didn’t sink in. There’s no easy way into the Hades matrix.’

  ‘No, I remember that. But there is a way, even if it involves dying, isn’t there?’

  ‘There was another way, but there’s no guarantee it still works. Dying is the only way I know. And I’m not going there again, not in this life or the next.’

  Thorn looked down, his face a mask that she found difficult to read. Was he disappointed or understanding? He had no idea what it had been like to fall towards Hades knowing that certain death awaited her. She had been resurrected once, after meeting Sylveste and Pascale, but there had been no promises that they would repeat the favour. The act itself had consumed a considerable fraction of the computational resources of the Hades object, and they — whoever were the agents that directed its endless calculations — might not sanction the same thing again. It was easy for Thorn; he had no idea what it had been like.

  Thorn…‘ she began.

  But at that moment pink and blue light stammered across the side of his face.

  Khouri frowned. ‘What was that?’

  Thorn turned back towards space. ‘Lights. Flashing lights, like distant lightning. I’ve been watching them every time I walk past a porthole. They seem to lie near to the ecliptic plane, in the same half of the sky as the Inhibitor machine. They weren’t there when we left orbit. Whatever it is must have started in the last twelve hours. I don’t think it’s anything to do with the weapon itself.’

  ‘Then it must be our weapons,’ Khouri said. ‘Ilia must have started using them already.’

  ‘She said she’d give us a period of grace.’

  It was true; Ilia Volyova had promised them that she would not deploy any of the cache weapons for thirty days, and that she would review her decision based on the success of the evacuation operation.

  ‘Something must have happened,’ Khouri said.

  ‘Or she lied,’ Thorn said quietly. In the shadows he took her hand again, and with one finger traced a line from her wrist to the conjunction of her middle and forefingers.

  ‘No. She wouldn’t have lied. Something’s happened, Thorn. There’s been a change of plan.’

  It came out of the darkness two hours later. There was nothing that could be done to prevent some of the occupants of the transfer craft from seeing Nostalgia for Infinity from the outside, so all Khouri and Thorn could do was wait and hope that the reaction was not too extreme. Khouri had wanted to slide baffles across the portholes — the ship was of too old a design for the portholes to be simply sphinctered out of existence — but Thorn had warned her that she should do nothing that implied that the view was in any way odd or troublesome.

  He whispered, ‘It may not be as bad as you expect. You know what a lighthugger’s meant to look like, and so the ship disturbs you because the Captain’s transformations have turned it into something monstrous. But most of the people we’re carrying were born on Resurgam. Most of them haven’t ever seen a starship, or even any images of what one should look like. They have a very vague idea based on the old records and the space operas they’ve been fed by Broadcasting House. Nostalgia for Infinity may strike them as a bit… unusual… but they won’t necessarily jump to the conclusion that she’s a plague ship.’

  ‘And when they get aboard?’ Khouri asked.

  ‘Now that might be a different story.’

  Thorn, however, turned out to be more or less correct. The shocking excrescences and architectural flourishes of the ship’s mutated exterior looked pathological to Khouri, but she knew more about the plague than anyone on Resurgam. It turned out that relatively few of the passengers were as disturbed as she had expected. Most were prepared to accept that the flourishes of diseased design served some obscure military function. This, after all, was the ship that they believed had wiped out an entire surface colony. They had few preconceptions about what it should look like, other than that it was, by its very nature, evil.

  ‘They’re relieved that there’s a ship here at all,’ Thorn told her. ‘And most of them can’t get anywhere near a porthole anyway. They’re taking what they’re hearing with a large pinch of salt, or they just don’t care.’

  ‘How can they not care when they’ve thrown away their lives to come this far?’

  ‘They’re tired,’ Thorn told her. ‘Tired and past caring about anything except getting off this ship.’

  The transfer craft executed a slow pass down the side of Infinity’s hull. Khouri had seen the approach enough times to view the prospect with only mild interest. But now something made her frown again.

  ‘That wasn’t there before,’ she said.

  ‘What?’
r />   She kept her voice low and refrained from pointing. ‘That… scar. Do you see it?’

  ‘That thing? I can’t miss it.’

  The scar was a meandering gash that wandered along the hull for several hundred metres. It appeared to be deep, very deep, in fact, gouging far into the ship, and it had every sign of being recent: the edges were sharp and there were no traces of any attempts at repair. Something squirmed in Khouri’s stomach.

  ‘It’s new,’ she said.

  Chapter 32

  THE TRANSFER SHUTTLE slid alongside the larger spacecraft, a single bubble drifting down the flank of a great scarred whale. Khouri and Thorn made their way to the rarely used flight deck, sealed the door behind them and then ordered some floodlights to be deployed. Fingers of light clawed along the hull, throwing the topology into exaggerated relief. The baroque transformations were queasily apparent — folds and whorls and acres of lizardlike scales — but there was no sign of any further damage.

  ‘Well?’ Thorn whispered. ‘What’s your assessment?’

  ‘I don’t know,’ she said. ‘But one thing’s for sure. Normally we’d have heard from Ilia by now.’

  Thorn nodded. ‘You think something catastrophic happened here, don’t you?’

  ‘We saw a battle, Thorn, or what looked like one. I can’t help jumping to conclusions.’

  ‘It was a long way off.’

  ‘You can be certain of that, can you?’

  ‘Fairly, yes. The flashes weren’t spread randomly around the sky. They were clustered, and they all lay close to the plane of the ecliptic. That means that whatever we saw was distant — tens of light-minutes, maybe even whole light-hours from here. If this ship was in the thick of it, we’d have seen a much larger spatial extent to the flashes.’

  ‘Good. You’ll excuse me if I don’t sound too relieved.’

  ‘The damage we’re seeing here can’t be related, Ana. If those flashes really were on the far side of the system, then the energy being unleashed was fearsome. This ship looks as if it took a hit of some kind, but it can’t have been a direct hit from the same weapons or there wouldn’t be a ship here.’
