Wilma is a Witches Assistant and former toad familiar.
A decade ago she was turned into a human so she could better assist her witch companion with housework, brewing potions and running errands in the city.
This might seem odd like an odd turn of events- but it's actually quite a common step Elderly witches and their loyal familiars take, providing their magic is powerful enough.
Wilma's a peppy, friendly girl, who can come across as an air-head to people who don't know her well- she's actually very book-smarts when it comes to occult matters.
Wilma's spent most of her life living in Lady Oak's cottage deep in the forest, so she is a bit sheltered. The bright lights of void city never fail to amaze her & she always tries to see the good in people.
