Devils vs Demons
There is actually a difference between Devils & demons.
Demons are lowly creatures that live in the darkest places of the Unconscious Sea. They are the stuff of nightmares & rule over fear. These creatures are tamed through the spells & rites of Therionick Sorcery & the Witches Sabbat. They have many bestial & atavistic aspects because they are embodiments of primal instincts. Through discipline & training they become Familiars. These are not to be confused with Devils.
Devils are the Lords of the Earth. They are embodiments of different aspects of Nature (and human nature), in which the Bucca (Satan) & the Fairy Queen (Lilith) is their King & Queen. These go by many names throughout different cultures but are initially the same. Most people call them Fairies.
