Fortress Vader

Fortress Vader, also known as Darth Vader's castle, was a stronghold located on the volcanic world of Mustafar. Once the site of a Sith temple, the fortress was built above a Sith cave that still remained, as well as the ancient Corvax Fortress located underneath. Existing by the time of reign of the Galactic Empire, the Sith cave contained a dark side locus.

The castle was designed by the preserved consciousness of the ancient Sith Lord and artist Darth Momin, whose haunted mask possessed an Imperial lieutenant and made him create the fortress's blueprints. Momin meant for it to channel the Force energies from the dark side locus under the castle and open the door to the dark side. The Sith Lord Darth Vader allowed Momin's design to be built using Imperial resources in his possession. Although Vader failed to open the door with the first design, after a trial and error process involving eight more designs, a perfect design was finally built with the ninth. It was able to open the door to the dark side, but when Vader was distracted by a Mustafarian uprising, Momin opened it for himself and resurrected his original body.

Despite Vader's intervention, the army of Mustafarians were able to wipe out the Imperial garrison. Vader retreated to the castle and used its power to do the same to the Mustafarians. Momin then confronted Vader and was able to badly damage Vader in their brief duel. Vader crushed him using a stone slab. With Momin, the Mustafarians, and the Imperial garrison dead, Vader was left alone to open the door to the dark side himself. Vader's spirit entered the portal in search of his dead wife, Padmé Amidala. He returned unsuccessful and used the fortress' power to destroy the portal. He then contacted his master, Darth Sidious, to confirm his planned return to Coruscant. Later, an Imperial Inspector got driven insane by lava fumes by Vader, creating Vader`s servant Vaneé. Ever since then, Vaneé became a devoted servant to Darth Vader.

The castle came to serve as Vader's personal residence and from time to time, he rested inside a bacta tank. On one occasion, his stasis was cut short by Director Orson Krennic of the Death Star project. The two discussed the project at hand. Vader also conversed with Admiral Kendal Ozzel and General Maximilian Veers there about the over stretching efforts to defeat the Rebel Alliance. After Vader`s death, Vaneé attempted to resurrect his master, after hearing the seeming ghost of his master, but it turned out to be a hallucination. Vaneé would be trapped by his own nightmares for a time before escaping and continuing lurking beneath the castle. Fortress Vader would later fall into disrepair, and by the time of the First Order-Resistance War, the rotting castle would be guarded by the Alazmec of Winsit. Vader's grandson, First Order Supreme Leader Kylo Ren, would eventually visit the castle grounds in search of Vader's Sith wayfinder.
