Fables Light is an almost entirely narrative roleplaying game. A typical game has one to five characters, called Protagonists, and a Director (or GM) that establishes the setting, plays the Antagonists (non-player characters), and resolves any issues that cannot be resolved through collaborative narration. Additionally, the Director is responsible for taking notes and compiling a post-game summary.
The game is concerned with recreating exciting scenes, linked together by narrative arcs to create a campaign. Characters are defined as players see fit, but generally follow a description with personality elements and traits. They grow and change as the game progresses. The rules essentially deal with methods to streamline activity and provide for speedy, exciting play.
