Star Wars: The Old Republic

The Star Wars: The Old Republic story takes place in the Star Wars fictional universe shortly after the establishment of a tenuous peace between the re-emergent Sith Empire and the Galactic Republic, 300 years after the events of the Star Wars: Knights of the Old Republic games, and more than 3,500 years before the events in the Star Wars films. The Jedi are held responsible for the success of the Sith during the devastating 28-year-long Great Galactic War (which led to the Treaty of Coruscant prior to the “cold war”), and thus choose to relocate from Coruscant to Tython, where the Jedi Order had initially been founded, to seek guidance from the Force. The Sith control Korriban, where they have re-established a Sith Academy. The game begins 10 years later as new conflicts arise.
Players join as members of either of the two main factions – the Galactic Republic and the Sith Empire. Although each faction is led by a benevolent or malevolent leader, it is emphasized that an individual member may possess a morality at any point along the light/dark spectrum. The project’s key focus is to differentiate between the player’s faction and morality.[17] For instance, a member with ties to the Galactic Republic may belong to the Dark Side while attempting to achieve their own ends, which may be misaligned or dissimilar from the Republic’s vision.
