So obviously, Mirialans are a Republic species (at least originally). However, if you look at the map of the galaxy (for example this one), you can see that the planet Mirial (border of squares P4-Q4 on the map) is right next to the Imperial core (Korriban and Ziost, square Q5 on the map).
So is there any way Mirial is still part of the Republic? You'd think it would be one of the first to fall when the Sith attacked, during or shortly after the Tingel Arm campaign. Is Mirial occupied by the Empire and are player Mirialans refugees? Wookieepedia sheds no light on the issue (other than saying that Mirial did briefly join the Empire during the Jedi Civil War). I was wondering if there's any official word on the matter, or whether people here have some ideas.
