Liana Idian was a female Selkath from Manaan, a completely water-covered world renowned for its Kolto production. Apprenticed to Olren Baran, Idian joined the Army of Light to fight against the Brotherhood of Darkness at the end of the New Sith Wars. Idian, unlike her master, survived the war, and went on to become a Jedi Master herself, before being killed twenty-six years after the end of the New Sith Wars by Darth Zannah and her apprentice Darth Cognus, whom Idian had recently discovered to be the only surviving Sith Lords.
