Darth Mordius was a Human male Jedi Knight and later, a Sith Lord who lived during, and served in, the Mandalorian Wars and the Jedi Civil War. Mordius, born Kratis Mordrey, was one of the many Jedi who joined the Jedi Knight Revan and his friend Alek Squinquargesimus in defying the Jedi High Council and aiding the forces of the Galactic Republic, who were locked in a struggle with the armies of the Mandalorian Neo-Crusaders. Mordrey saw considerable action during the war and, by the time of the war's final battle, had been given command of a squadron of Interdictor-class cruisers.
