The game takes place in the fictional floating world of Cocoon, whose government, the Sanctum, is ordering a purge of civilians who have supposedly come into contact with Pulse, the much-feared world below.
“We were all born and raised on Cocoon. But three years ago, our home basically fell out of the sky. We couldn’t rely on the broken fal'Cie anymore, so most of us made the decision to move to Pulse. Our leader, Snow, suggested we live somewhere near the ocean. We used to live in a seaside town on Cocoon, so it was like we were rebuilding our home.”
