Head southeast and go into the small house to find Barret and talk him into joining up with you again. Head back to where you first entered the prison and go north through the gate where the dead body is. From there head right through a gap in the fence and then up. Barret will have to battle Dyne alone.
Afterwards, Ester will take Cloud up to the Golden Saucer join the Chocobo Race. In the meeting room, pick up the Ramuh. In a little while Ester will return and the race will begin. If you don't win, you'll have to keep trying until you do. After you win, Dio will free all of you and give you a Buggy so you can cross the desert.
|Notes:||Once you have the Buggy you can cross not only the desert, but you also the shallow spots in rivers too. You'll still have to battle enemies while driving it however.|
