I don't know anything about that race so I'll be going to Google straight on from here. My question isn't speciific to Miraluka but definitely applies to them.
When an entire race has a strong affinity for the Force, how does the Empire respond?
I'm guessing that each member of a race with a Force Rating has a very large chance of becoming a Jedi. They're definitely a ready pool of recruits for anyone trying to rebuild a Jedi order. So I think the Empire would be pretty hard on them. Quarentine them to a single world, hunt down any who violate quarentine, keep them repressed and controlled... at best.
If I'm right, that would make playing such a character pretty difficult.
