Fueled by their rage wraiths come from varying backgrounds and deaths that were unjust such as accused of crimes they didn't commit which resulted in their death, victims of those in power like servants who were treated so terribly eventually dying from mistreatment. A few have dark occult history when they were alive and were sacrificed in some way. The list is vast of their cause for needing vengeance. The injustice they felt at the moment of their death transformed them into fearsome spirits. They are skilled in vengeance, retribution, and protection, curses, helping to open the third eye, communication with the dead, the ability to slow or speed time in the mind. This can seem like a time shift to their human companion in order to focus on a project or one's self. Though it does not physically alter time this illusionary magic still produces that effect. House rules are needed as well as telling them who to not strike in retribution.
