Anyway, the Sanctum discovered the fal'Cie that had branded Serah. They shipped everyone in Bodhum off to Hanging Edge to be killed. Called it the 'Purge', pretended they were relocating people to Pulse. I tried to get Serah back to the fal'Cie, but it stole her away when they were taking it, too... Lightning was part of the GC at the time. She quit, made them Purge her. Then she broke out of their train, all to get to the fal'Cie that branded her sister.
