Pulse & Cocoon/ XIII

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.
