The Tomb of Freedon Nadd was a mausoleum that served as the final resting place for the physical remains of King Ommin and Queen Amanoa of Onderon, as well as their Sith ancestor, the Dark Lord Freedon Nadd. The original tomb, which consisted of nothing more than Nadd's sarcophagus within a hollowed section beneath the royal palace of Iziz, was cleansed of its potency with the end of the planet Onderon's Beast Wars. After the final defeat of Freedon Nadd's worshipers in 3998 BBY, Jedi Master Arca Jeth ordered the construction of a new tomb on the nearby jungle moon Dxun to contain Nadd's remains and their residual dark side energies. Entombed alongside the Dark Lord were Queen Amanoa and King Ommin, with whom died the last vestiges of Nadd's Sith dynasty.
