I can handle anything but that goddamn statue, I don't care how bad it is lol

I genuinely think the series is fun and I like it, but when I recommend it I give like 20 warnings, and tell them to either skip book six, or just cut their losses after five.

The lore of the movie is different and obviously less developed than the book series, but as far as we know she was the first witch of the east, following Ozma being deposed as an infant by either the wizard or the witches working in tandem, depending on who is telling the story and which point in the series you pay attention to. The books contradict each other extensively, but one of the more consistent versions has Ozma as either a fairy left behind by the fairy queen Lurline or a direct descendant of the same, so there wouldn't have been a witch ruling in the east until maybe 10-12 years before Dorothy got there.
