I saw a trailer for the new Old Republic thing, with the two guys who I think are brothers, and their creepy dad(?). One is in all white, one is in all black. I tried to read up on this on Wookieepedia, but then it was giving me really incomplete and conflicting info. I was hoping someone could explain this. Thank you.
