I think making Jakku in/near Imperial space makes perfect sense. Canonically it is on the edge of the Unknown Regions, where the First Order apparently has been hiding. It’s also where the Empire made their last stand, so it would make sense for it to be near some kind of Imperial/Republic border.

How would you go about showing this vision? A prophetic vision, so someone Force-sensitive would have had this vision to motivate the Resistance to find Luke. I’m guessing Leia? That could work. But personally I think it just comes down to Luke Skywalker being Snoke’s greatest threat. He is clearly afraid of him, thinking it would be Luke that would “rise to meet the darkness”. I even think destroying the Republic/Resistance with Starkiller was an afterthought, and he mainly helped the First Order build it so he could find out wherever Luke was and blow up the entire system he was in. He was that afraid of him returning.

Though the whole vision theme could make sense since you are giving Rey more visions.

Yeah, it is fun to talk about them! We will work on the TFA crawl forever and then spend months on the TLJ crawl too, probably. Hopefully it won’t take as long though!

Also I’m sure you have already talked about this but were you planning to eventually do prequel edits? Just curious.
