Ozma
Ozma is the daughter of the mad king Pastoria and thus the hereditary ruler of Oz. She spent most of her childhood under an enchantment, raised by the witch Mombi, as a boy named Tip. That enchantment was broken shortly before her thirteenth birthday and she was shortly installed in the throne. Despite having lacking any childhood training, she took to the role of Queen quite easily and has lead her kingdom through a myriad of trials and tragedies with wisdom and poise.
