The Wonderful Wizard of Oz except the Good Witch of the North from Baum's books, NOT GLINDA.

In Baum's books, Glinda rules the South, where her color is red or pink, and the blue land of the Munchkins is ruled by The Good Witch of the North. It is she who Dorothy meets after landing in Oz in the book. (Her white hair would not have worked in technicolor and they would not have cast a little old lady.)

[She should look more like an old version of Frozen's Elsa (but with wings) than like Glinda.]

[The Good Witch of the North doesn't have a name in the book. Baum called her Locasta in one project late in life and in official Oz books after Baum's Death she's called Tattypoo. In The Wiz (Movie) she's Miss One. ]
