Yeah, that's EXACTLY the sort of feeling I want. They probably settled matters rather peacefully before, because the way their hormones and mental processes are set up and the way life on their original planet was probably developed... They didn't know much strife and didn't need to compete for resources.

It'd have to be a planet in which they probably developed a means of survival pre-sentience that involved just not getting eaten, so they're probably omnivores that favor plantlife.

I imagine they have very little natural aggression, and so they themselves make really awful combatants whose instincts in such situations would NORMALLY scream "flight." It had to have taken severe training and diligence to get to the point where they could fight back against the X'cor... after, y'know, already being bombed and conquered and enslaved.

I haven't decided if this fleet consists of former slaves OR consists of the remnants of the race that escaped conquest. I'm leaning toward the latter, thus why they still have their own vessels.
