Based on the d20 role-playing system, Knights is set some thousands of years before any of the movies, at a time when Jedi are plentiful. The ever-present war between the dark and light sides of the Force is the centrepiece of the story, focusing on a pair of Jedi, Revan and Malak, who fell to the dark side after a mysterious journey to an unexplored corner of the galaxy. Players also get an insight into the training process of both the Jedi Academy and the Sith.
