The inclusion of Darth Vader’s castle on Mustafar – the planet where the Dark Lord formerly known as Anakin Skywalker became a quadruple-amputee, got his skin burned off, and had to be rescued so he could be put on life support – was an unexpected surprise in Rogue One: A Star Wars Story. But its brief appearance in that movie might not be the last time we see it on film, according to Lucasfilm’s Vice President/Executive Creative Director Doug Chiang.
Doug Chiang, who did concept art for The Phantom Menace, Attack of the Clones, and The Force Awakens, recently talked about why they chose to revisit Mustafar in Rogue One. As it turns out, it’s because the place is simply so important to Darth Vader:
It’s interesting, we did a lot of history exploration… For us, it was really figuring out that Vader built his castle on an existing structure, which was this ancient lava dam. And he built it here for a very specific reason. It was to come back here to meditate, to rejuvenate, to reconnect with himself. And it became a very spiritual place, and it was all centered around his bacta tank.
As mentioned above, the planet holds a great degree of significance to Darth Vader due to his past there, which is why they included it as a part of the character’s introduction. Chiang also noted that there was a lot to the castle that we have yet to see, and that we might yet get a look at in another movie:
…We’ve done quite a bit of exploration of what’s on the inside of [the castle] as well, and hopefully that’ll be seen in some other film.
It’s worth keeping in mind that there was a rumor not too long ago that suggested that a return to Mustafar – and more specifically, Darth Vader’s castle – was on the cards. It would not be too surprising to see Kylo Ren visit the planet as a way of connecting with his idol.
