So, for your SW character. I was thinking that you are enslaved by the Empire to work on the Tarisian Imperial Reclamation Initiative (IRI). Your ancestors survived crashing on a moon far-away from civilization 80 years before the Trade Federation's blockading of Naboo.

Your small clan had to rely on less and less technology and more on skill and what your family could remember. You could track and kill a Gizka from 50 yards away using a bow and arrow. You were discovered by opportunistic colonists who arranged a deal with some local slavers who brought you to the Empire. You are on an inbound flight to Taris.

(I can make shit up).

I keep my background obscured to protect my family's village.
