Rosch ' s voice - over talks about how the Sanctum announced the Purge as a relocation to Pulse , though it was a ruse to hide its true nature as the method of taking everyone in the town and exterminating them in an uninhabited place on Cocoon ' s outskirts where the massacre would go unseen by the rest of Cocoon . As footage ranging from Lake Bresha to the " Palamecia " plays , Rosch ' s voice - over reveals the ' confirmed ' assumption that the l ' Cie sought to " bring harm to Cocoon " , the army tracking Lightning and Hope on their journey from the Vile Peaks to Palumpolum , and the all - out military effort to kill the four l ' Cie in Palumpolum to prevent another Purge from taking place .
