The one question on everyone's lips during Star Wars: The Force Awakens was: where the hell is Luke Skywalker?!
The Jedi master was noticeably absent - banished to the wilderness, only to return in the closing moments of the film.
But why? A new fan theory may have the answer.
YouTuber Thor Skywalker is saying that it is all down to Supreme Leader Snoke.
The claim goes that Snoke predates the First Order and is the one responsible for turning Kylo Ren to the dark side. And since Kylo massacred Luke's Jedi apprentices, Luke had in fact set off on a quest to discover the first ancient Jedi.
The YouTuber goes on to say: "Snoke is old. He even predates the Sith and is likely the first Dark Side user in the galaxy."
"He may be the one who inspired the Sith and trained them at one point, but considered himself above them, almost like a god. He used the Sith to rule the galaxy and was defeated thousands of years ago when the first Jedi emerged and imprisoned him in a distant part of the galaxy."
Star Wars screenwriter, Michael Arndt had previously claimed that Skywalker's absence was down to a simple case of upstaging.
"It just felt like every time Luke came in and entered the movie, he just took it over," Arndt said at a post-screening Q&A back in 2015.
"Suddenly you didn't care about your main character anymore because, 'Oh f***, Luke Skywalker's here. I want to see what he's going to do.'"
We guess we'll just have to wait until Star Wars Episode 8 is released this December to find out whether Luke was on a quest to defeat the dark side, yet again.
