I’m sorry if I came off too strong, I like the current crawl, I’m only voicing my opinion on what could possibly improve it.
Even if you need to mention Mustafar, I think it could be worded better to imply Kylo has been doing more in search of Exegol before the attack on Mustafar. When we see him on the surface killing everyone he seems to be in a manic state, as if he’s been chasing this phantom for a while now. I feel that’s how it worked in the original crawl since it said Kylo “rages in search of the phantom Emperor”.
