Born and raised in the woods by her parents in order to escape slavery, Arlene spent most of her days practicing her magical abilities. Sometime after her parents passed away, she found employment as a maid to Theodore Griffin and his family, though they keep up the charade that she is their slave.
While a loyal friend and confident, Arlene is not above putting her safety above others. She is willing to do whatever it takes to make sure she comes out on top when things go wrong. She has a grudge against humans for forcing her fellow witches into submission as she believes witches are the superior beings.
- In The Devils of Salem it is hinted that Arlene practices Dark Magic.
