Marvel Comics writer Charles Soule let slip Darth Vader’s castle secrets in the latest issue of the Star Wars comic. The castle in question first appeared in the film, Rogue One: A Star Wars Story. It was on the same planet where Darth Vader had his final duel with Obi-Wan Kenobi in Star Wars: Episode III-Revenge of the Sith. In Rouge One, the film’s main antagonist, Orson Krennic, went to Darth Vader to get his help against Grand Moff Tarkin. Charles Soule’s spin on the book has been primarily focused on the bridge between the infamous ‘I don’t like sand’ Anakin Skywalker from the prequel trilogy to badass, Dark Lord of the Sith. This has included an explanation on how Darth Vader obtained his first red lightsaber, the hunting down of the Jedi who survived Order 66 and going deeper into just why he joined the dark side, to begin with. In addition, it also gives us answers as to why he decided to build his house on Mustafar, to begin with. This latest issue the book reveals his true reason behind putting his base in such a morbid place. In the first image shown, it is revealed that in the depths of the castle is what is described as a door to the dark side. Apparently, by going through it, Darth Vader will be able to meet with the soul of Padme. Excited to discover more? The feeling is mutual.
