Magic Forums

So, I?ve ran into a type of spirit that I cannot identify. They look like demons, except they?re white cloaked instead of black. In my experience and based on what I?ve read about people?s experience of them on Reddit, they?re evil. However, no one on there knows what they are. I can?t find them in my encyclopedia of spirits or with a Google search. I?m at a complete loss but would love to know just for the sake of interest, and I?d love to experiment with working with them.
