o far what we do know about the movie is that Luke Skywalker's lightsaber crash lands on a planet where it is found by the characters played by Daisy Ridley and John Boyega. This leads them on a search to find Luke, during which time they come across Han and Chewie. They team up and continue to search for Luke who has been missing since the events of Return of the Jedi. Apparently Luke is being held captive.
Now on to some new information! The villains of the film are the Inquisitors, who are loosely based on the Inquistors from the Expanded Universe. We've previously heard these referred to as Jedi Hunters. The are described as being "mixed with the hardended Sith look of Rebels' villain." They are the defenders of the Sith Order and they’ve been around for a very long time. The site goes on to explain:
When our hero(es) find Luke and the Inquisitors are revealed, Luke’s explanation on the history of this order is going to trigger a flashback to explain that the Inquisitors have been tied into the Sith all along.
That flashback is said to include a much younger Princess Leia that will be played by Carrie Fisher's daughter, Billie Lourd, as previously rumored.
One other huge thing that we will see in this flashback are the Inquisitors serving none other than Darth Vader! That's right folks, it sounds like Vader will be making his return to the big screen as well. It will only be a brief one, but he'll be there! Suddenly that "far-fetched" rumor about WWE Superstar Sheamus being in Episode VII doesn't seem so crazy anymore.
