there is a glacier whitch i've fought her three times. if you ask the guy at the bar in icicle town he'll say something about a witch. after you beat her she'll drop the alexander materia. you fight her by touching the hot springs then you go to the part where u lay the markers and try to find a little hut. go in it and then leave and then find the cave and she'll be sittin there and u talk to her and she says not to touch her wuth those filthy hands that touched the hot springs. then u fight and beat her. she looks look like the chick with the frogs acceept blue.
