Oscar Diggs

It's the man behind the curtain himself. The real wizard of oz aka Oscar Diggs aka professor marvel. He's gone by many names in the past, as he's even impersonated a guard at the emerald city just to explore oz without being noticed. After you killed the wicked witch of the west and brought back her broomstick like he asked, he says he can't grant your wish to send you home because he needs think about it. Naturally, you get pissed, and you end up discovering the giant gas monster you thought was the wizard of oz was an illusion. You find Oscar Diggs hiding behind the green curtain, and he explains to you he's just a normal human with no powers, so he apologizes. You can be whoever you want, and it's up to you if you're alone with Oscar or not.
