The Worst Witch
Mildred "Millie" Hubble is the protagonist of the series. She is a good-hearted, but bungling young witch-in-training, who never seems to get anything right. She is friends with Maud Spellbody and Enid Nightshade and has a strong rivalry with Ethel Hallow. It is Miss Hardbroom, her potions teacher, who calls her "The Worst Witch".
Good Witch of the North
In 2000, Dave Hardenbrook published "The Unknown Witches of Oz", with Locasta, the Good Witch of the North, as the main protagonist. Dave Hardenbrook wished to reconcile L. Frank Baum's original version of the character with Ruth Plumly Thompson's version. In Hardenbrook's novel, Locasta and Queen Orin were "switched" by Mombi, the same way Mombi "switched" herself with the maid Jellia Jamb in L. Frank Baum's novel, "The Marvelous Land of Oz". Locasta, the true Good Witch of the North, was lost in the Great Outside World, while the enchanted Queen Orin took her title under the name of Tattypoo. Hardenbrook's novel outlines Locasta's return to the Land of Oz.
