‘Perhaps,’ Thorn said. ‘There’s certainly speculation along those lines. But there’s no sign that any major planets have ever been dismantled in this system before, no resonance gaps in orbits where a Jovian would have belonged. But then again, it was a million years ago. Maybe the Inhibitors tidied up after they’d done their dirty work.’
‘Inhibitors?’ asked a bearded man whom Thorn recognised as an unemployed palaeobotanist.
‘That’s what the government calls the alien machines. I don’t know why, but it seems as good a name as any.’
‘What will they do to us?’ asked a woman who had exceptionally bad teeth.
‘I don’t know.’ Thorn tightened his fingers around the edge of the podium. He had felt the mood of the room change within the last minute. It always happened this way, when they saw what was happening. Those who knew of the thing in the sky had viewed it with alarm from the moment the rumours began. For most of the year it had not been visible at all from Cuvier’s latitude, where most of the citizenry still lived. But no one had been of the opinion that it was likely to be a good omen. Now it had hoved into the evening sky, unignorable.
The government’s experts had their own ideas about what was going on around the giant. They had correctly deduced that the activities could only be the result of intelligent forces, rather than some outlandish astronomical cataclysm, although that had, for a while, been considered. A minority considered it likely that the agency behind the destruction was human: the Con-joiners, perhaps, or a new and belligerent group of Ultras. A smaller and less credible minority thought that the Triumvir herself, Ilia Volyova, had to have something to do with it. But the majority had correctly deduced that alien intervention was the most likely explanation, and that it was in some way a response to Sylveste’s investigations.
But the government’s experts had access only to the sketchiest of data. They had not glimpsed the alien machinery in close-up, as Thorn had.
Volyova and Khouri had their own theories.
As soon as the arc was finished, as soon as the giant had been girdled, there had been a dramatic change in the properties of the planet’s magnetosphere. An intense quadrupole field had been set up, orders of magnitude more intense than the planet’s natural field. Loops of magnetic flux curled between lines of latitude from equator to pole, ramming far out of the atmosphere. The field was clearly artificial, and it could only have been produced by current flow along conductors laid along those lines of latitude, great metallic loops wound around the planet like motor windings.
That was the process Thorn and Khouri had observed with their own eyes. They had watched the loops being laid, spooled deep into the atmosphere. But they had no idea how deep they had gone. The windings must have sunk far into the metallic hydrogen ocean, deep enough to achieve some kind of torque coupling with the planet’s shrivelled yet immensely metal-rich rocky kernel. An exterior acceleration force transmitted to the windings would be transferred to the planet itself.
Meanwhile, around the planet, the orbital arc generated a pole-to-pole current flow, passing through the giant and returning to the arc via the mag-netospheric plasma. The charge elements in the ring reacted against the field in which they were embedded, forcing a tiny change in angular momentum in the motor windings.
Imperceptibly at first, the gas giant began to rotate faster.
The process had continued for most of a year. The effect had been catastrophic: as the planet had spun faster and faster, so it had been pushed closer and closer towards the critical break-up velocity when its own gravity could no longer stop it from flying apart. Within six months, half the mass of the planet’s atmosphere had been flung into space, ejected into the half-beautiful, half-repulsive new circum-planetary nebula that was visible from Resurgam as a thumb-sized smudge in the evening sky. Now most of the atmosphere was gone. Relieved of the compressive weight of the overlying layers, the liquid-hydrogen ocean had returned to the gaseous state, liberating squalls of energy that had been pumped smoothly back into the spin-up machinery. The metallic-hydrogen ocean had undergone a similar but even more convulsive state change. That too had been part of the plan, for the great process of dismantling had not faltered once.
Now all that remained was a husk of tectonically unstable core matter spinning close to its own fragmentation speed. The machines were surrounding it even as Thorn spoke, processing and refining. In the nebula, revealed as shadowy knots of coherent shape and density, other structures were taking shape, larger than worlds in their own right.
Thorn said again, ‘I don’t know what’s happening. I don’t think anyone does. But I do have an idea. What they’ve done so far has been very hierarchical. The machines are awesome, but they have limitations. Matter has to come from somewhere, and they couldn’t immediately start smashing apart the gas giant. They had to make the tools to do that, and that meant smashing three smaller worlds first. They need raw material, you see. Energy doesn’t seem to be a problem — maybe they can draw it directly from the vacuum — but they obviously can’t condense it back down into matter with any precision or efficiency. So they have to work in stages, one step at a time. Now they’ve ripped apart a gas giant, liberating perhaps one-tenth of one per cent of the entire useful mass in this system. Based on what we’ve seen so far, that liberated mass will be used to make something else. What, I don’t know. But I’m willing to hazard a guess. There’s only one place to go now, only one hierarchy above a gas giant. It has to be the sun. I think they’re going to take it apart.’
‘You’re not serious,’ someone said.
‘I wish I wasn’t. But there has to be a reason why they haven’t smashed Resurgam yet. I think it’s obvious: they don’t have to. In a while, perhaps much sooner than we’d like, there won’t be any need for them to worry about it. It’ll be gone. They’ll have ripped this solar system apart.’
‘No…’ someone exclaimed.
Thorn started to answer, ready to work on their understandable doubts. He had been through this before, and he knew the truth took a while to sink in. That was why he told them about the shuttles first, so that there would be something they could pin their hopes on. It was the end of the world, he would say, but that didn’t mean they all had to die. There was an escape route. All anyone needed was the courage to trust him, the courage to follow him.
But then Thorn realised that the person had said ‘no’ for an entirely different reason. It had nothing to do with his presentation.
It was the police. They were coming through the door.
He jumped from the podium. The police were masked, unrecognisable. They came in with sprays and pacifiers at the ready, moving through the stunned and frightened audience with quick jerky movements and no audible communication. Thorn hit the ground and dashed towards the escape route, the one that would lead to the getaway car two blocks away. Make it look real. Make it look bloody real. He heard chairs scraping as people stood or tried to stand. The crack of fear-gas grenades and the buzz-snap of stun guns filled the room. He heard someone cry out, followed by the sound of armour on bone. There had been a moment of near calm; now it was over. The room erupted into a panicked frenzy as everyone tried to get out.
His exit was blocked. The police were coming in that way as well.
Thorn spun around. Same story the other way. He started coughing, feeling panic rise in him unexpectedly, like a sudden urge to sneeze. The effect of the fear-gas was so absolute that it made him want to crawl into a corner and cower rather than stand his ground. But Thorn fought through it. He grabbed one of the chairs and raised it aloft as a shield as the police stormed towards him.
The next thing he knew he was on his knees, and then his hands, and the police were hitting him with sticks, expertly aimed so that he would have bruises but no major broken bones or internal injuries.
Out of the corner of his eye, Thorn saw another group of police laying into the woman with the bad teeth. She disappeared under them, like something mobbed by rooks.
