She formed a hypothesis. It was not difficult. The cubes had glued themselves on to the outside of Galiana’s ship. They had multiplied, growing as they absorbed and reprocessed the ship’s integument. In that respect it was indeed a little plaguelike. But the plague was microscopic; one never saw the individual elements of the spore with the naked eye. This was more brutal and mechanistic, almost fascistic, in the way it replicated. The plague at least imbued transformed matter with something of its earlier characteristics, yielding chimeric phantasms of machine and flesh.
No, Skade told herself. She was certainly not dealing with the Melding Plague, as comforting as that might now have been.
The cubes had wormed into the ship and then formed attacking units — soldier conglomerations. These soldiers had done the killing, advancing slowly away from each infection point. Judging by the remains they were lumpy and asymmetric, more like dense swarms of hornets than individual entities. They must have been able to squirm through the tiniest opening, reassembling on the other side. Nonetheless, the battle had taken time. By Skade’s estimate, it might have taken many days for the whole ship to fall. Many weeks, even.
She shivered at the thought of it.
A day after they had first entered, her servitors found some human bodies that were nearly intact, except that their heads had been swallowed by black helmets of surrounding cubes. The alien machinery appeared inert. The servitors removed parts of the helmets and found that prongs of machine-growth reached into the corpses’ skulls, through the eye sockets or the ears or the nasal cavity. Further study showed that the prongs had bifurcated many times, until they reached microscopic scale. They extended deep into the brains of the dead, establishing connections with their native Conjoiner implants.
But the machines, and their hosts, were now very much dead.
Skade tried to work out what had happened; the ship’s records were thoroughly scrambled. It was obvious that Galiana had encountered something hostile, but why hadn’t the cubes simply destroyed her ship in one go? The infiltration had been slow and painstaking, and it only made sense if the cubes wanted to keep the ship intact for as long as possible.
There had been another ship: two had gone on — what had happened to that one?
[Ideas, Skade?]
Yes. But nothing I like.
[You think the cubes wanted to learn as much as possible, don’t you?]
I can’t think of any other reason. They put taps into their minds, reading their neural machinery. They were intelligence-gathering.
[Yes. We agree. The cubes must have learned a great deal about us. We have to consider them a threat, even if we don’t yet know where Galiana was when they found her. But there is a glimmer of hope, wouldn’t you say?]
Skade failed to see what that glimmer could possibly be. Humanity had been searching for an unambiguous alien intelligence for centuries. All they had found so far had been tantalising leads — the Pattern Jugglers, the Shrouders, the archaeological remains of another eight or nine dead cultures. They had never encountered another extant machine-using intelligence, nothing to measure themselves against.
Until now.
And what this machine-using intelligence did, so it seemed, was stalk, infiltrate and slaughter, and then invade skulls.
It was not, Skade conceded, the most fruitful of first encounters.
Hope? Are you serious?
[Yes, Skade, because we don’t know that the cubes were ever able to transmit that knowledge back to whatever it was that sent them. Galiana’s ship made it back home, after all. She must have steered it here, and she would not have done that if she thought there was any danger of leading the enemy back to us. Clavain would be proud, I think. She was still thinking of us; still thinking of the Mother Nest.]
But she ran the risk…
The voice of the Night Council cut her off sharply. [The ship is a warning, Skade. That is what Galiana intended and that is how we must read it.]
A warning?
[That we must be ready. They are still out there, and one way or another we will meet them again.]
You almost sound as if you were expecting them to arrive.
But the Night Council said nothing.
It was another week before they found Galiana, for the ship was vast and there had been many changes to its interior that prohibited a rapid search. Skade had gone inside it herself, along with other sweep teams. They wore heavy ceramic armour over their pressure suits, oiled carapacial plaques that made movement awkward unless one exercised great care and forethought. After several minutes of fumbling and locking herself into postures that could only be got out of by laborious back-tracking, Skade wrote a hasty body-image/motion patch and assigned it to run on a clump of idle neural circuits. Things became easier then, though she had the unpleasant feeling that a shadowy counterpart of herself was driving her. Skade made a mental note to revise the script later, so that the movement routines would feel totally voluntary no matter how illusory that might be.
By then the servitors had done about all they were able. They had secured large volumes of the ship, spraying diamond-fibred epoxy over the ruins of the alien machines, and they had DNA-sampled most of the corpses in the explored zones. Every individual sample of genetic material had been identified against the crew manifests in the Mother Nest, preserved since the departure of the exploratory fleet, but there were many names on the list that had yet to be matched to DNA samples.
There were bound to be names Skade would never match. When the first ship had returned home, the one carrying Clavain, the Mother Nest had learned that there had been a decision in deep space, dozens of light-years out, to split the expedition. One party wanted to come back home, having heard rumours of war against the Demarchists. They also felt that it was time to deliver the data they had already accrued — far too much to be transmitted home.
The separation had not been acrimonious. There had been regret, and sadness, but no real sense of disunity. After the usual period of debate typical of any Conjoiner decision-making process, the split came to be viewed as the most logical course of action. It allowed the expedition to continue, while safeguarding the return of what had already been learned. But while Skade knew exactly who had chosen to stay out there in deep space, she had no way of knowing what had happened subsequently. She could only guess at the exchanges that had taken place between the remaining two ships. The fact that this was Galiana’s ship did not mean that she had to be on it, so Skade readied herself for the inevitable disappointment should that prove to be the case.
More than that, it would be a disappointment for the entire Mother Nest. Galiana was their figurehead, after all. She was the woman who had created the Conjoiners in the first place, four hundred years ago and eleven light-years away, in a huddle of labs beneath the surface of Mars. She had been away for nearly two centuries; long enough to assume the mythic stature that she had always resisted during her time amongst them. And she had returned — if she was indeed aboard this ship — on Skade’s watch. It hardly mattered that she was very likely dead, along with all the others. For Skade, it would be enough to bring home her remains.
