The Massassi (/məˈsæ.si:/) were an ancient offshoot of the Sith species, initially mutated by the experiments of Naga Sadow and later driven to extinction by Exar Kun. A century before the Battle of Yavin, the Sith Lord and alchemist Khrado Ragnos used his powers and cloning techniques to revive the ancient race, growing himself an army which in later years would pass to his apprentice Tak Sakaros, and then to Tak's daughter Rin.
