Well, basically, you fly over to Wutai, a town on an island to the southwest. You enter with Yuffie in your party and she comes out and says something like, "I know this area pretty well." Shinra soldiers come and you have to fight them. But that greedy thief Yuffie has stolen every last bit of materia from you! So in this battle, you're materia-less. Well, Yuffie is nowhere to be found. So you must be detectives and find her. You go into a house and look behind a changing room type thing. Yuffie runs away. Then you look into a cement jar outside of the bar. She'll take you to her house and trap you in cages. Free yourselves by pulling the lever. Go to the place where the pagoda is. Ring the bell. Go into the door that just opened. Yuffie and Elena of the Turks is being kidnapped by Don Corneo's men. (Yes, you do meet the Turks ;) Go to the mountain and look for the Don. Don Corneo will sick his pet bird dragon thing on you, of coursed you'll win, well, then you save Yuffie and Elena, and then Yuffie gives you back your materia. She puts it on all wrong though. Major bummer. It takes kind of a while to get the order perfect, but oh well. Have fun
