Your at your "home" again shall we say. This part of the game is just, depressing. Here you find out many things that are crucial to the story. The fiends here are like mini-bosses. So make sure you're ready. Go inside the dome and travel through as watching the ghostly images on your way. You'll see many of Jecht , Braska, and Auron and then one of Seymour and his mother. Then be prepared for a cloister of trials.
