Revan, renowned as the Revanchist, dreaded as the Sith Lord Darth Revan, and honored as the Prodigal Knight, is one of the central protagonists of the Star Wars Old Republic era.

He was an eminent Jedi Knight turned Dark Lord of the Sith until, stripped of his true persona, he returned to the crumbling Jedi Order and helped defeat the Sith Empire he had established. A human male, and acknowledged as a very gifted and powerful Force-sensitive pupil, he was trained as a Padawan by Kreia and a number of other Jedi Masters, both on Coruscant and at the Jedi Enclave on Dantooine.

Due to his actions, philosophies, and involvement in major pivotal events and conflicts of the Old Republic era, Revan is arguably one of the most important characters of the entire Star Wars franchise due to his influence in the Old Republic series as well as his posthumous influence on the philosophies of the Sith centuries later.

He was voiced by Rino Romano in Knights of the Old Republic (2003), and Jeff Bennett in The Old Republic (2011).
