Thirteen centuries ago, a fal'Cie, preternatural being formed by the crystal residing inside it, created a floating, utopian city in the atmosphere of a planet known as Pulse. The fal'Cie willed that the city be completely isolated from the crude and brutal wilderness below, and commissioned machines to be the guardians of the citizens. Barriers were subsequently set up all around the city, and as such was the metropolis granted its befitting name: Cocoon.

Having lived secluded from the outside world for many years, the citizens of Cocoon are now becoming anxious of what Pulse really holds. Recent contact with those from the world below has caused people to question one another and their ways of life. Wised up to the word on the street, the Sanctum of Cocoon have decreed a new edict: Any individuals suspected to be in contact with the world of Pulse are to be banished from the city unconditionally and cast into the harsh environment of the planet below.

In tandem with the increasing uneasiness among the citizens of Cocoon, the believers of destiny are now painting the gloomiest of futures: the downfall of the entire world. Belief has it that the fal'Cie residing on Pulse has sought a woman to destroy the world and its inhabitants. This woman goes by the codename Lightning. The fal'Cie force Lightning and her companions to do its bidding, marking them as the l'Cie and giving them the power of the crystals. The l'Cie struggle against their destiny, but how can they rebel against beings worshipped by people as gods?
