From the witch herself:
I am Anaïs Blue. Seventeen years of age. Trapped in the body of a five-year-old. And a witch.
You see, we grow different to the rest of you guys. It kind of sucks but It’s not all bad.
At least I get to experiment on naturals like you.
If you were in London recently our paths may have crossed.
Then your world probably looked a little different for few hours. My caretaker told me I should apologise.
I’ve also been told I should explain myself. This story should help clear it up.
