Aston stared at her, stomach heaving as the implications sank in.
"Yes, Ster Aston," she said coldly. "They decided, in your idiom, to set a thief to catch a thief. If humans could out-think and out-fight them, they needed humans of their own. Their cyborgs were never quite as good as having regular humans, and they've never trusted them entirely. Strategy and sensitive research are still in strictly Kanga hands, but tactics and actual combat are another matter. Their cyborgs are completely expendable, and obedience is engineered into them; they can't even argue about being expended, but they're very good at what they do.

"My God," he whispered, holding his cold pipe.
"God had very little to do with it," she said softly, "and the hell of it is that the cyborgs hate us even more than the Kangas do. We're the ones who keep killing them, but, in a sense, we're also related, and it horrifies and disgusts both of us. They're slaves to the Kangas; even if we wanted to, we could never forget that, and they know it.

They got them, too. The first time we cornered some of them and tried to talk to them, they slaughtered our entire contact team—over a hundred people—even though they knew we had enough troops and firepower to exterminate them.
"In two hundred years, every single confrontation
