Walsh

Walsh is the current Wizard of Oz and thusby ruler of Emerald City. He is young and sometimes insecure about his job.

History
He was born and raised in Emerald City as the son of Queen Ozma's proudest knight, who died in war. When Queen Ozma died, there were no royal succesors to become Wizard of Oz and ruler of Emerald City. The Sisterhood of Witches took care of this and elected Walsh, still in his 20s to be the new (and first non-royal) Wizard of Oz.
