Focus (Fabula Nova Crystallis)

Focus is the term for the missions given to the l'Cie by the fal'Cie. Each l'Cie is given a Focus that is a mission unknown to them, and if he or she fails to complete it, the l'Cie will turn into a monster known as a Cie'th. But the reward for completing a Focus is not much better, for the l'Cie will be turned into a crystal though is still preferred over the alternative of becoming mindless beasts that may attack their former friends. Therefore, that is why most Cocoon citizens consider it a 'curse' to become a l'Cie.Focuses are given to the l'Cie through visions and they must interpret these visions to know what the mission requires them to accomplish. In some cases, after completing the focus, the l'Cie brand may get burnt out after becoming a crystal, thus they can have the benefits of l'Cie power without having to complete a Focus, free from the fear of becoming a Cie'th or Crystal.

At the Pulse fal'Cie, Serah is shown becoming a crystal as she completed her Focus by luring more people to Anima to become l'Cie.

Furthermore, fal'Cie also possess their own Focus, one of which is not to destroy Cocoon. But some found a loophole to have l'Cie carry out the deed for them.
