Have I created a unique headcanon for my characters? Hell yes! Pull up a chair, this could take a while.
My headcanon for them relies on both what info I've found in Wookieepedia and best guesses made from what the game gives us (that I've encountered so far). I've never read any Old Republic era fiction and I didn't play the KoTOR games. And I can't seem to find much information about either Republic or Sith Empire society, as a whole or by planet. If one can wild mass guess by oneself, I've done so.
