A new trailer for Final Fantasy XIII-2 has been released, and provides more insight into what the story will entail. It seems the events at the conclusion of Final Fantasy XIII opened a rift to another world, which is where Lightning ends up. The rest of the cast will travel back and forth between their world and this new one, it seems. I'm really digging some of the new character designs. And Caius looks like a cool antagonist - from this trailer alone, I'm sold on this sequel.
