I don’t suppose there’s any way we could integrate RLM’s Ewok death cult idea? I really wish we’d gotten it. I’m picture a barely living corpse covered in cybernetic implants (preferably with spider legs) being worshipped by mangey, cannibalistic Ewoks, who have been nursing him back to health with the flesh of their enemies. Integrating all that is impossible, but maybe we could have Exegol as some part of Endor, related to the Death Star wreckage (canonically two different moons, but whatever)? There’d be some close ups revealing the Sith cultists to be mangey Ewoks? I know it probably wouldn’t work, but it’s just a thought.
On a different note, I was thinking of perhaps having the cultists visibly chanting. I know it’s implicit they’re chanting in the film, but I’m talking close-ups where their mouths move to the music. Bonus points if they sing Duel of the Fates.
