To be fair that's 99% of the real appeal of star wars and a thing that they kinda fucked up by doing many of them. Having a cool looking dude show up in a couple of shots leaves you to wonder about who he is. Which is a fun way to world build through background characters and not hand holding and being like "oh that's Jamp Lorkel, he fought the Myths Order at Belto 5 along with Zunk Weedum and the Jantrabs. Disney is making a five part miniseries about his contribution to the unrest on Valtrex Ten. He eats Wheaties for breakfast and he loves romantic walks at dusk. He's looking for a homemaker who isn't too religious but still goes to church. He's 4/20 friendly and likes dogs."
