History
Frank Baum who was a member of the Men of Letters traveled on a case, and his daughter Dorothy snuck along with him. Dorothy got trapped in Oz and fought the Wicked Witch of the West with three freedom fighters who were later cursed by her to become the Scarecrow, Tin Man and Cowardly Lion. The Tin Man and Dorothy both died during the adventures, but while Dorothy was resurrected, the Tin Man was not and Dorothy kept his head to honor him.
After the Witch came to Earth, L. Frank Baum wrote the books off of Dorothy's adventures to give her clues on how to deal with the Witch. The Witch tried to find the key that was int he possession of the me of Letetrs, which opens a portal to Oz, so that she could complete her war.
After the Witch was killed in 2013 by Charlie Bradbury, Dorothy and Charlie returned to the realm to free it from the Witch's forces and to find Dorothy's dog Toto.
