Get ready to (maybe) return to the Dark Side, Star Wars fans! Thanks to an eagle-eyed blogger, Darth Vader is rumored to make a grand onscreen return to the sci-fi film franchise in the upcoming spinoff, Rogue One: A Star Wars Story.

On May 17, a German fansite called JediBibliothek uncovered what appears to be the cover and ten draft pages of an as-yet-unpublished forthcoming film guide for the movie. Reportedly titled Rogue One: A Star Wars Story - The Official Visual Story Guide, the book—which is allegedly due on shelves January 2017 and seems to be a work-in-progress—contains a number of potential plot and character spoilers, as well as a plethora of images from the film... including a massive illustration of the OG Sith Lord looming over both Rebel Alliance fighters and Galactic Empire stormtroopers alike.

The foreboding image suggests that Vader may play a more integral role in the film's story-line than previously thought. In addition, the artwork only fuels earlier speculation that Welsh actor and "special creature performer" Spencer Wilding (Guardians of the Galaxy, Harry Potter) may portray the man formerly known as Anakin Skywalker in the forthcoming motion picture, as opposed to Hayden Christensen, who played the hero-turned-villain in the series' prequels.

However, only time will tell if fans will truly be graced by Vader's booming voice and shiny black space armor once more—seven months, to be exact. Rogue One opens December 16.
