Well, I'm using some of Robotech's novel canon to explain it in quite a (I hope) clever way, that sort of links into some of the established Canon, while making it different enough that meta-gaming - not that any of you would do that - shouldn't be an issue either. 
I'll also be spicing things up by throwing in and adapting bits of Macross Canon too, and shifting things about a bit in the timeline as well, so some things will appear earlier or later, just so it fits what I want it too.
