Lioko was a Sith Lord who lived during the Republic Dark Age. In c. 1032 BBY, Lioko's grandmother Vilia Calimondra ordered her grandchildren to attack the territories of the Quermian Sith Lord Ayanos Bactra, and Lioko captured a proportion of Bactra's holdings. After Odion recovered the Helm of Ieldis and attempted to destroy the galaxy by driving all life into a homicidal frenzy, Lioko contributed warships to an allied armada assembled by Vilia to stop Odion's nihilistic ambitions from succeeding.
