Will-O'-The-Wisps are minor agents of fate that help lead people to something of importance. A riddle, an epiphany, a place, a person, it varies depending on what is set for the person following them.
They consist of harmless light of a variety of colours and have no corporeal form. They can not be touched nor harmed and are unaffected by barriers. They are silent beings and communicate much in the way of pets.
