Pavia Anduru, or as some people refer to her: Nightshade.
Pavia is a White Witch by trade, only wanting to serve, and help people with her vast Knowledge... however in Spectre's Pass(Her Hometown) she's often under minded since she can't get control of her tail, not just because of the Town's standards, but because her tail, and Saliva contains a Venom similar to the Nightshade Plant, as to why, she doesn't know, but believes it's aftermath of self experimentation, Many doubt that.
