XoXaan's tomb

XoXaan's tomb was a Sith mausoleum situated on Korriban, specifically inside the well-known Valley of the Dark Lords on that planet. It served as the burial place for XoXaan, a Dark Jedi who was one of those who took over Korriban and subsequently became the initial Sith Lords. A'Sharad Hett, at the time a bounty hunter, came across the tomb in 17 BBY after he perceived XoXaan's voice beckoning to his inherent darkness. Hett proceeded into the tomb and located XoXaan's holocron within, using it to acquire knowledge of the Sith's practices; upon his exit, he had transformed into a different person—Darth Krayt, a Dark Lord of the Sith. This Sith mausoleum was quite significant.
