Guh, I just read through this whole thread in search of info for my star charts. I am truly, deeply apologetic to you, Crazen, for underestimating the quality of your creation. This is truly one of the diamonds in the rough, no matter how repellent the below-average punctuation may be to Grammar Nazis. I salute you and greatly look forward to more information on these guys.
On another note, I'm assuming that the Graid's interstellar possessions are comparatively low in number. I read just one reference to "the colonies," and most info was just about Earthsky. One moon was classified as a defensive fortress and these guys are well-equipped for defensive fighting. That and their very homeworld-centric culture implies to me that their exoplanetary dominions are insignificant in size. So am I correct in assuming that they don't have much beyond Earthsky?
