In the Star Wars galaxy, no location is more fearsome or intimidating than Darth Vader's castle on the planet Mustafar. Originally teased in Star Wars Rebels, Darth Vader's castle made its live-action debut in Rogue One: A Star Wars Story. It's proven to be one of the most compelling new locations in Star Wars, appearing in everything from comics to VR games. Vader's castle may have appeared on-screen many times, but its origins are actually told in the Darth Vader (2017) comic book series by Charles Soule and Giuseppe Camuncoli.

There's something so wonderfully intimidating about Vader's dark castle, constructed near the very same lava flows where Obi-Wan defeated Anakin in Star Wars: Episode III - Revenge of the Sith. It's become far more than just a lair for Darth Vader; it now stands as a symbol of its might. Mustafar even appeared in Star Wars: The Rise of Skywalker, with Kylo Ren seeking Darth Vader's Wayfinder on the planet. Here's everything to know (so far) about Darth Vader's fortress on the lava world of Mustafar.

Why Darth Vader Built His Castle On Mustafar

Shortly after the events of Revenge of the Sith, Darth Vader was tasked to fulfill critical training now that he was officially a Sith Lord. This included finding and killing a Jedi master, claiming his lightsaber as his own. As was tradition for the Sith, Vader poured all of his pain, suffering, and rage into the lightsaber's living kyber crystal, bleediing it to create a true Sith lightsaber. Palpatine told Vader to do this on Mustafar, a planet rich in the dark side of the Force.

This vergence was probably the reason Palpatine had the Separatists sent to Mustafar before ordering Vader to kill them - unaware his new apprentice would soon fall in battle with Obi-Wan Kenobi there. Vader's subsequent meditations on Mustafar convinced him the vergence was truly powerful, and he dreamed of using its power to resurrect Pé. Although Darth Sidious originally offered Vader planets such as Naboo or Tatooine to call his own, Darth Vader demanded (and was given) the planet Mustafar instead.

Fortress Vader’s Origin, Design & Ancient Sith Powers Explained

Darth Vader used the spirit of the ancient Darth Vader did try to bring his Pé back (but was ultimately unsuccessful).

Fortress Vader was still where Darth Vader was at his most powerful.

However, Fortress Vader was still where Darth Vader was at his most powerful. Granted, it was also where he could be his most vulnerable. Featuring medical facilities and a large tank full of healing bacta, the Dark Lord was able to remove his helmet, armor, and life- systems to briefly alleviate his damaged body and tissue. When Vader was away serving his master, the fortress was looked after by his attendant Vaneé and guarded by a personal garrison of black-armored Lava Troopers, with breathing apparatuses mirroring the Dark Lord himself,

Where Else Darth Vader’s Castle Has Appeared In Star Wars Movies & Shows

Although Fortress Vader made its first debut in Rogue One, the castle has been featured in other Star Wars projects as well. Beyond the comics and novels, Fortress Vader has most recently been seen in Obi-Wan Kenobi. Initially suspended within his bacta tank, Vader donned his cybernetics and armor before receiving a report from the Inquisitor Third Sister, providing a look at the throne room. Fortress Vader was also included among several different vistas in 2021's Star Wars Biomes released on Disney+, a short feature that showed the castle and the surrounding lava-covered region.

The canonical VR experience Vader Immortal was also set within Fortress Vader, revealing even more secrets like the fact that Vader's castle was not only built atop a locus of dark side energy but also an ancient fortress belonging to Lady Corvax, a Force-sensitive who's actions turned Mustafar into its present hellscape, rather than the world lush with life it was centuries before. Mustafar and the ruins of Fortress Vader were also briefly visited by Kylo Ren and the First Order at the beginning of Star Wars: The Rise of Skywalker.

Kylo Ren & The Legacy Of Vader’s Castle

Even after Darth Vader's death in Return of the Jedi, his legacy was still felt on Mustafar. Although Fortress Vader fell to ruin during the New Republic Era, the world was visited by Kylo Ren shortly after he became Supreme Leader of the First Order. Idolizing his grandfather's darkness like Darth Vader (and ignoring his redemption as Anakin Skywalker), Kylo battled several Mustafarians to claim the Sith Wayfinder that led him to the secret Sith world of Exegol and Darth Sidious. This was the very same Wayfinder Vader found on Mustafar decades earlier, as seen in the comics.

Mustafar's Fortress Vader has a long and dark history that spans many years across the Star Wars timeline. As much more secrets about the castle continue to be revealed with new stories, such as the currently ongoing comic where the Knights of Ren broke into the castle and battled with Vader in between episodes of the original trilogy. Without a doubt, it's a structure that's as dark and intimidating as the Dark Lord of the Sith himself.
