Darth Vader's Castle In 'Rogue One': Your Questions Answered

The first question I've seen a lot of people asking is "where is this planet?" The answer to that question lies in Anakin Skywalker's tragic history. That's right; this is Mustafar, the volcanic planet we saw in Star Wars Episode III: Revenge of the Sith. The scorching lava world was where Obi-Wan Kenobi had the infamous lightsaber duel with Anakin Skywalker, which resulted in the loss of his limbs and severe scarring all over his body. It was basically the place that Darth Vader was born.

In the Art of Book, original screenwriter Gary Whitta says "the fact that he has chosen to build his mausoleum here is a nod to the conflict in him — that he would go back to this place to reflect on what happened to the man he once was. At the same time, it's also terrifying, and when he emerges with all of his armor, he's Darth Vader."

After seeing the film, some fans have theorized that Vader's attendant becomes Snoke, the leader of Kylo Ren and the First Order as seen in Star Wars: The Force Awakens. This seems unlikely at best.

But I have heard that we will see more of this location in the future of Star Wars stories. If that means the comic books, novels or Star Wars: Episode VIII, we don't know. It has been rumored that some aspect of this film is a set-up for something we will see in Rian Johnson's eighth installment of the Skywalker saga. After seeing the movie a second time, it seems as if Vader's castle would be the most likely.

Even the Art of Rogue One book hints that this location may be featured in future Star Wars projects:

Vader's Mustafar castle in Rogue One would be concepted, designed, and explored beyond even the narrative needs of Rogue One itself. "We were building worlds, so we always had to keep in mind the broad strokes and the big picture, in case they were needed for the story," said [Doug] Chiang.

The above concept art came from the Art of Star Wars: The Force Awakens book. While it was assumed that it was an early concept for what became Maz's castle, it now seems as if they adopted it for Rogue One.

We first see Vader's attendant Vanee visiting Vader as he meditates within a rejuvenation chamber — this is a call back to when we first saw Luke Skywalker submerged in a Bacta Tank to recover from his wounds in Empire Strikes Back. The concept art above was posted by IO9.

Concept artist Christian Alzmann talks about the idea behind the Bacta tank in the Art of Rogue One Book that "this is where Vader stays, because it's the only place he feels comfortable."

"The idea is that he would have a massive cylindrical machine in the center of his room — and in the center of that machine is a one-person bacta tank that looks out through a window onto the lava fields of Mustafar. It's both a meditation and a healing chamber. There's a lava river underneath, bottom-lighting the room earily. These arms would come down to pull apart the chamber the way you might seperate a pill capsule, and the bacta would leak out on the hot grills to create steam — partially because steam is so atmospheric and awesome, and partially because you don't really want to see a naked Vader. But there would be hints and glimpses of his twisted body breaking through the steam. And then, at the end, you might barely read a silouette of the helmet as it comes down."

Original screenwriter Gary Whitta says the original idea was that Vader "would need to sometimes remove all of his armor to completely replenish his depleted body, but that his private place wasn't actually an Imperial location–but we pictured it as this really dreadful place with Albert Speer-like brutalist architecture."

Whitta also says the image of Vader in the take makes you realize that "he's this crippled, broken, tragic figure." Whitta says that when Lucasfilm head Kathleen Kennedy saw the concept art for the bacta tank, she "really responded to the idea that Vader would choose for himself such a hellish kind of chamber."
