But she found more than remains.
Galiana’s resting place, if it could be called that, was a long way from the central core of the ship. She had secured herself behind armoured barricades, well away from the others. Careful forensic study showed that the data links between Galiana’s resting place and the remainder of the ship had been deliberately severed from within. She had obviously tried to isolate herself, cutting her mind off from the other Conjoiners on the ship.
Self-sacrifice or self-preservation? Skade wondered.
Galiana was in reefersleep, cooled down to a point where all metabolic processes were arrested. But the black machines had still reached her. They had smashed through the armour of the reefersleep casket, cramming themselves into the space between Galiana and the casket’s interior surface. When the casket was dismantled, the machines formed a mummylike shell of pure black around Galiana. There was no doubt that it was she: scans peering through the cocoon picked out bone structure, which matched Galiana’s perfectly. The body within appeared to have suffered no damage or decay during the flight, and the sensors were even able to pick up weak signals from Galiana’s implant web. Although the signals were too faint to allow mind-to-mind linkage, it was clear that something inside the cocoon was still capable of thought, and was still reaching out.
Attention shifted to the cocoon itself. Chemical analysis of the cubes drew a blank: they appeared not to be ‘made’ of anything, or to possess any kind of atomic granularity. The faces of the cubes were simply blank walls of sheer force, transparent to certain forms of radiation. They were very cold — still active in a way that none of the other machines had been so far. But the individual cubes did not resist being prised away from the larger mass, and once they were separated they shrunk rapidly, dwindling down to microscopic size. Skade’s team attempted to focus scanners on the cubes themselves, trying to glimpse anything buried beneath the facets, but they were never quick enough. Where the cubes had been they found only a few micrograms of smouldering ashes. Presumably there were mechanisms at the heart of the cubes that were programmed to self-destruct under certain circumstances.
Once Skade’s team had removed most of the surrounding plaque, they took Galiana to a dedicated room nestling in one wall of the spacecraft bay. They worked in extreme cold, determined not to inflict more damage than had already been done. Then, with immense care and patience, they began to peel away the final layer of alien machinery.
Now that they had less obstructive matter to peer through, they began to get a clearer impression of what had happened to Galiana. The black machines had indeed forced their way into her head, but the accommodation appeared more benign than had been the case with any of her crew. Her own implants had been partly dismantled to make way for the invading machines, but there was no sign that any major brain structures had been harmed. Skade had the impression that the cubes had been learning how to invade skulls until then, but that with Galiana they had finally found out how to do it without hurting the host.
And now Skade felt an optimistic rush. The black structures were concentrated and inert. With the right medichines it would be possible — trivial, even — to dismantle them, ripping them out cube by cube.
We can do it. We can bring her back, as she was.
[Be careful, Skade. We’re not home and dry just yet.]
The Night Council, as it transpired, was right to be cautious. Skade’s team began removing the final layer of cubes, beginning at Galiana’s feet; they were pleased when they found that the underlying tissue was largely undamaged, and continued to work upwards until they reached her neck. They were confident that she could be warmed back to body temperature, even if it would be a more difficult exercise than a normal reefersleep revival. But when they began to expose her face, they learned that their work was far from over.
The cubes moved, slithering without warning. Sliding and tumbling over each other, contracting in nauseating waves, the final part of the cocoon oozed into Galiana like a living oil slick. The black tide sucked itself into her mouth, her nose, her ears and her eye-sockets, flowing around her eyeballs.
She looked the way Skade had hoped she would: a radiant homecoming queen. Even her long black hair was intact, frozen and fragile now, but exactly as it had been when she had left them. But the black machinery had reestablished itself inside her head, augmenting the formations that were already present. Scans showed that there was still little displacement of her own brain tissue, but more of her implant loom had been dismantled to make way for the invader. The black parasite had a crablike aspect, extending clawed filaments into different parts of her brain.
Slowly, over many days, they brought Galiana back to just below normal body temperature. All the while Skade’s team monitored the invader, but it never changed, not even as Galiana’s remaining implants began to warm and re-interface with her thawing brain tissue.
Perhaps, Skade dared to wonder, they might still win?
She was, it turned out, almost right.
She heard a voice. It was a human voice, feminine, lacking the timbre — or the strange Godlike absence of timbre — that ordinarily meant that the voice was originating inside her skull. This was a voice that had been shaped in a human larynx and propagated through metres of air before being decoded by a human auditory system, accumulating all manner of subtle imperfections along the way. It was the sort of voice that she had not heard in a very long time.
The voice said, ‘Hello, Galiana.’
Where am I?
There was no answer. After a few moments the voice added kindly, ‘You’ll have to speak as well, if you can. It’s not necessary to do more than attempt to make the sound shapes; the trawl will do the rest, picking up the intention to send electrical signals to your larynx. But simply thinking your response won’t work, I’m afraid — there are no direct links between your mind and mine.’
The words seemed to take an eternity to arrive. Spoken language was horridly slow and linear after centuries of neural linkage, even if the syntax and grammar were familiar.
She made the intention to speak, and heard her own amplified voice ring out. ‘Why?’
‘We’ll come to that.’
‘Where am I? Who are you?’
‘You’re safe and sound. You’re home; back in the Mother Nest. We recovered your ship and revived you. My name’s Skade.’
Galiana had been aware only of dim shapes looming around her, but now the room brightened. She was lying on her back, canted at an angle to the horizontal. She was inside a casket very much like a reefersleep casket but with no lid, so that she was exposed to the air. She saw things in her peripheral vision, but she could not move any part of her body, not even her eyes. A blurred figure came into focus before her, leaning over the open maw of the casket.
‘Skade? I don’t remember you.’
‘You wouldn’t,’ the stranger replied. ‘I didn’t become one of the Conjoined until after your departure.’
There were questions — thousands of questions — that needed to be asked. But she could not ask all of them at once, most especially not via this clumsy old way of communicating. So she had to begin somewhere. ‘How long have I been away?’
‘One hundred and ninety years, almost to the month. You left in…’
‘2415,’ Galiana said promptly.
‘…Yes. And the present date is 2605.’
There was much that Galiana did not properly remember, and much that she did not think she wanted to remember. But the essentials were clear enough. She had led a trio of ships away from the Mother Nest, into deep space. The intention was to probe beyond the well-mapped frontier of human space, exploring previously unvisited worlds, looking for complex alien life. When rumours of war reached the three vessels, one ship had turned back home. But the other two had carried on, looping through many more solar systems.
