Oz

Oz is a realm and land. It is seperated in five different sections: Emerald City, the North, the East, the South and the West. Each section has it's own ruler but the Wizard of Oz is king in Emerald City and the most powerful of all rulers. Once upon a time, the Wizard had to be from the noble house of Oz but after Queen Ozma died, that rule changed.

Witches
Oz traditionally had no rulers over all the land but during Queen Ozma's reign, Glinda selected three other witches and herself to form the Sisterhood of Witches. Every witch now rules one part of the country:
 * Glinda (The Witch of Love) rules the South.
 * Oriënta (The Witch of Courage) rules the East.
 * Sapienta (The Witch of Wisdom) rules the North.
 * Zelena (The Witch of Innocence) rules The West.
