I don't even know her past. xD What I have on her bio right now is a bunch of bullshit that never happened. It's just her excuse to not talk about stuff that happened.
I'm still trying to put the bits and pieces together.
The song is about a specific event. What I have so far on her past is that she was actually born in a REALLLYYY Amish village. Like, they still did not allow dancing and stuff like that. And having the magical powers she did, as a little girl, she wasn't able to control them very well. So once the village found that she was practicing dark magic, they tried to get her executed and called her a witch, etc.. That's why she hates being called a which.
And then I have something about how she ran away with a man(later, her trainer) who visited the village one night and beckoned her away. I'm debating with myself about what makes that man so very shocking and different from other wizard trainers. I have a few ideas.
