Revan is a human Jedi who led the Republic to victory in the Mandalorian Wars, returned as a Dark Lord of the Sith at the head of an invasion, and was captured, mind-wiped and rebuilt by the Jedi Council as a blank-slate operative. Revan belongs to the Old Republic era, and was introduced in BioWare's Star Wars: Knights of the Old Republic (2003).
The twist
The game's structure is the character. You play an amnesiac Republic soldier and spend twenty hours discovering that you are the enemy you have been hunting — and then you choose what to do about it. Because the player also chose the character's gender, alignment and face, no single canonical Revan was ever fully fixed, and the Legends material afterwards had to work around that gap.
Homeworld and identity
The world Deralia appears in the game as part of Revan's implanted false identity, not as a verified birthplace, so this dossier records no homeworld. That ambiguity is the point: Revan is a person assembled out of other people's decisions about who they should be.
In print
Drew Karpyshyn — lead writer on the original game — later wrote the novel The Old Republic: Revan (Del Rey, 2011), which fixes the character's post-game history and ties it into the Star Wars: The Old Republic MMO. It is divisive precisely because it resolves things many readers preferred unresolved.
Legends only
The entire Old Republic period, roughly four thousand years before the films, is Star Wars Legends — Tales of the Jedi is where the shelf invented it. Current canon has never dramatised it and the era slug used on this site for that period is a publishing label, not a shared continuity. Read it as its own self-contained shelf.
