<P> Schematically, Oz is much like the United States, with the Emerald City taking the place of Chicago: to the East, mixed forest and farmland; to the West, treeless plains and fields of wheat; to the South, warmth and lush growth, and red earth . </P> <P> Ruth Plumly Thompson took a different direction with her Oz books, introducing European elements such as the title character of The Yellow Knight of Oz, a knight straight out of Arthurian Legend . </P> <P> At the time of The Wonderful Wizard of Oz, the lands in the North, South, East and West of Oz are each ruled by a Witch . The Witches of the North and South are good, while the Witches of the East and West are wicked . Glinda (the Good Witch of the South) is later revealed to be the most powerful of the four, although later Oz books reveal that the Wicked Witch of the West was so powerful, even Glinda feared her . After Dorothy's house crushes the Wicked Witch of the East, thereby liberating the Munchkins from bondage, the Good Witch of the North tells Dorothy that she (the Witch of the North) is not as powerful as the Wicked Witch of the East had been, or she would have freed the Munchkins herself . </P> <P> During the first scene in Oz in The Wonderful Wizard of Oz, the Good Witch of the North (Locasta or Tattypoo) explains to Dorothy that Oz still has witches and wizards, not being civilized, and goes on to explain that witches and wizards can be both good and evil, unlike the evil witches that Dorothy had been told of . That book contained only the four witches (besides the humbug wizard), but despite Ozma's prohibition on magic, many more magicians feature in later works . </P>
