Rey will be heading to the Mountain Clan on account of being worried about them trying to incite a war due to her interrogation with Keith.

She will probably try to convince people to stop for the skirmishes along the way.

And once in the castle, she can jedi mind trick guards for added stealth points.

She doesn't know anything about politics really so as far as proposals go, she's mostly just gonna be listening to what other ppl think and settling on what sounds like it makes the most sense.
