A Sithri ceremonial sword from the Golden Age of the Sith which occurred more than 160,000 years prior to the battle of Yavin. During this period the Great Sith Empire faced off against the First Republic, and the predecessors of the Jedi- the Jai, with trade being centered around Rakis station, which served as a neutral ground for two radically opposed ideologies to meet. This ceremonial sword was presumably owned by Lord Oroslan Nevetto, the brother of Vitzesh Nevetto, and uncle to Lau'Ren Sadir. Oroslan preferred fighting with Sith Swords, forgoing the lightsabers of the era.
This particular example was merely used for ritual sacrifice and ceremonial purposes. Unlike most of the others of Nevetto line, Oroslan managed to survive the battle of Andar, and served as regent for several years over what little remained of the Nabataean Territories.
