The old world that was God's that ruled over humanity is now in the past. That means that the souls from the living and dead get reborn, and that means that some can get another chance to live again. After when Serah and the others landed, they eventually knew that not all went to the same place. It's now up to Serah, Snow, Vanille, and Serah to find the rest of her friends. And there would be help from the new souls, the people that had already had a life. So would this mean that the world was already occupied? Did Bhinvelsa lie?
