“distant worlds beyond the reach of the New Republic”- this seems repetitive. You’re saying the same thing twice because they both relate to how far away the worlds are. I’d replace the word “distant” with something else. I recommend “remote” to emphasize these worlds are isolated from other ones, too.
“hero of the legendary force” - I’m not entirely sure what you’re trying to say here. Are you talking about the Force? Idk the wording here just seems kinda clunky. I’d focus more on how they perceive Luke since that’s integral to the entire trilogy: “in search of the last Jedi, certain that only his faith can restore peace and justice to the darkening stars.” This is a play on words - they want his hope and optimism but also the faith itself of the Jedi.
