Fiyero

a handsome prince, fellow student, and love interest.

Fiyero is a Winkie prince. The Winkies inhabit one of the regions of Oz (as in Frank Baum's original). He begins as a carefree college-age hedonist who invites fellow students to party. He transforms as his romantic interests shift. . . .
