White Arts means the spell or spirit is purely good in its intentions; it is not capable of being bad. It is a positive, uplifting, and heart-warming energy. Dark Arts simply means it’s like a human being; capable of being good or bad. In the case of spirits they likely choose to do the right thing, as most humans do, but they have the freedom of choice. Black Arts means the entire intent of the spell or spirit is to be malicious & perform functions of harm to others.
