Man, character diversity in the PT is a major problem. Between Obi Wan, Anakin and Luke & Leia’s mother you have this kind of core trio that are presumably all Human and white, judging from the appearance of Luke and Leia.
I’ve tried to offset this with Darth Vader being alien and I’m considering making Zara Arcadia a Near-Human like a Miraluka or a Hapan or something, but then you’d expect to see some of those differntiating traits expressed in Luke or Leia.
Also I cannot for the life of me think how to work a substantial droid character into the story.
