In ‘Ghosts of Mortis’ Dark Revan was set to appear alongside Darth Bane as guiders to the Son. Darth Revan was initially slated to appear in The Clone Wars. While the infamous Sith Lord hasn’t had a prominent role in the established canon, his presence is gradually seeping through. Revan was first introduced as a playable character in Star Wars: Knights of the Old Republic in 2003. Together with his apprentice, Darth Malek, they wreaked havoc across the Galaxy, lightsaber in hand and the Dark Side of the Force at their disposal. In Legends, Darth Revan was once a Jedi Knight who turned to the Dark Side and became a powerful Sith Lord.
