Subsequently captured by the Jedi, Revan had his memory erased and was given a false identity, as part of the Jedi's plan to have Revan rejoin their ranks and help defeat Malak and his Empire. During a battle, Revan was betrayed and left for dead by his friend and Sith Apprentice, Darth Malak, who sought to usurp him.

After turning to the dark side and becoming a Sith Lord, he took on the name Darth Revan and formed a Sith Empire to conquer the galaxy, contending with the Republic's armies. Within the game's narrative, Revan is a former Jedi hero who lived during the Old Republic Era (roughly 4,000 years before the original Star Wars film trilogy). Players may choose Revan's gender, appearance, and what path he follows throughout the game, but canonically the character is male and follows the light side of the Force. Revan ( / ˈ r ɛ v ə n/) is a fictional character in the Star Wars franchise, created for BioWare's 2003 role-playing video game Star Wars: Knights of the Old Republic.
