So, I've talked it over extensively with my Co-GM, because we have very different views on the matter of the Astray. We would rather it not be used for reasons pertaining to its aesthetics (Namely its similarity to a Gundam in appearance), more specifically due to a plot point that an Astray would be a little weird to reconcile with.

That said, if it is [i]really[/i] important to you, it could be considered. It would, however, require fairly heavy aesthetic modification to be allowable. I'm sorry if that ruins an idea.

EDIT: Well, space probably isn't entirely uninhabited even now. It's just that it's too ravaged to be able to sustain a sizable population. So yes, that'd work.
