Slash Film's research into the origins of Darth Vader's castle also indicate that the location could play a major role in a future "Star Wars" film -- even, possibly, "Episode VIII." A passage from the "Art of Rogue One" book hints at its future role:

Vader’s Mustafar castle in Rogue One would be concepted, designed, and explored beyond even the narrative needs of Rogue One itself. “We were building worlds, so we always had to keep in mind the broad strokes and the big picture, in case they were needed for the story,” said [Doug] Chiang.

"Rogue One: A Star Wars Story" is in theaters now.
