Very few details for Disney’s first Star Wars spinoff have been revealed, and the first teaser trailer only added to the mystery. Thanks to a big info dump on Wednesday, however, we finally have more story details for Rogue One, including confirmation of a certain character’s return.

If you don’t want to know general story details for Star Wars: Rogue One, I suggest you avert your eyes.

The biggest reveal in a new story from Entertainment Weekly is the return of Darth Vader. We had heard the Sith Lord would make a triumphant return to the big screen—come on, think of the merchandising opportunities—and it sounds like he’ll actually feature in the film more than we expected.

More details about Vader’s involvement are on the way though his return to the Star Wars universe will apparently have big implications to the larger universe; vague, I know.

In addition, Entertainment Weekly’s story has also confirmed Mads Mikkelsen’s character (rumored name is Galen) is a scientist “whose knowledge is sought” by both the Rebellion and Empire; also important is the fact that he’s Jyn Erso’s father, which could give us insight as to how she eventually comes into possession of the Death Star plans.

We also get confirmation of a new vehicle called TIE Striker, while we’re promised candid details about those rumored reshoots. Specifically, what they’re adding to the story.

We should know much more soon. Star Wars: Rogue One hits theaters on Dec. 16, 2016.
