The history of the Galaxy is a continuous war. Four thousand years before the conflict between the Empire and the Rebel Alliance, battles raged across many worlds. First came the Mandalorian Wars, which nearly destroyed the Republic, followed by a massive invasion by the Sith Empire. This assault was led by former Jedi, who had once fought under the banners of the Republic against the Mandalorians. Now they turned their might against their former mentors.
The story of the knights of the Old Republic, fighting against the powerful Sith, begins with a battle in orbit around the planet Taris, where the burden falls on a mere Republic soldier to rescue a Jedi who, by chance, is caught in a planetary blockade. Following the knight, the soldier descends onto Taris, where a new chapter of his life begins, filled with the most unexpected discoveries.
