‘We nearly did the same. We lost planet after planet to it, and it subsumed and killed billions. We exterminated billions on the worlds we sterilized.’

Blegg decided he wanted to get straight to the point. ‘Was it a Pyrrhic victory in the end? Your civilization no longer exists, but then few Jain nodes exist either. The ones we are having trouble with now are those brought here by the Maker.’

That chuckle again. The gabbleduck stretched out one limb and opened out a hand composed of talons like black bananas. ‘You know that Jain technology is nanotechnology, but study it long enough and you find that its foundations go deeper. All matter is merely knotted space and time in the end, adhering to certain rules soon learnt by any sufficiently advanced species.’ Floating inside that claw appeared some construct of light. ‘When you organize the underlying structure of matter, the difference is always noticeable when observed from the right place.’ The creature turned to peer at him. ‘There is a price.’

‘Name it.’

‘You return us to the surface of the place you call Masada—home of the gabbleducks.’

Blegg considered that. The plan had been to keep the artefact aboard the Hourne so it could quickly be moved to different locations in the event of war. Such a repository of valuable information must be protected. However, the survival of the Polity might depend on being able to locate Jain nodes. He did not need to confer. He replied, ‘It will be done. You have my word, and that is good.’

‘I know—it’s the word of a ruler,’ the gabbleduck replied cryptically.

The construct drifted down from its claw, turning as it came. Blegg kept utterly still as it hovered before him, and as it drifted towards his forehead and penetrated. ‘The Jain used U-space, yet their destructive technology does not. It was made by their AIs, which were based on the Jain themselves as yours are on you, before those AIs transcended their erstwhile masters and left them to kill each other. Why they left the U-space option out is a question best addressed to those same AIs, wherever they might be.’

It was a pattern in his mind, seven, eight dimensional: something beyond what he could encompass, but at least recognizable as a U-space signature. With a sudden flush of excitement Blegg realized what he saw: a Jain node as viewed via underspace.

The gabbleduck peered down at him. ‘This is what you came for?’

‘It is.’

It nodded slowly. ‘You never get them all—there’re always some overlooked, to start the process all over again. There is only one way to win.’

‘And what is that?’ Blegg asked, wondering what the quickest way out of this realm might be.

‘You cease to be what the Jain hated.’

Blegg turned away.

Never.

Was that what the Atheter did? Hatred of the futility of intelligent life and technical civilizations . . .
