When Ozma first meets Dorothy, Oz's greatest heroine, in Ozma of Oz, they immediately like each other and become best friends; in the canonical Oz books by Baum, Dorothy and Ozma are each other's closest relationship. In The Emerald City of Oz Ozma arranges, at Dorothy's request, for Dorothy and her family to move into the palace, and Ozma declares her an official princess of Oz and her "constant companion". In The Lost Princess of Oz the first page mentions that Ozma loves Dorothy very much and by page two says that Dorothy is the only one privileged to enter Ozma's rooms without an invitation. In turn, Dorothy often represents Ozma when some task takes the latter away from the Emerald City.
