A Middle Eastern ''Demon Spirit'' – ''Sila'' are a Class of Evil Being – relative to The Jinn and Ghoul. The term is also associated with the Western concept of a ''Hag'' (today). The Sila were potent ''Shapeshifters'', sought after by many practitioners of ''Dark Magic'' as a ''Revenge Tool''. The Sila most like to assume the guise of a Human Man or Woman. In this form, they try to get a Human to ''fall in love with them''. Once done, a Child is conceived (Hybrid). This ''Sila'' then is transported back to The Sila's ''dimension'' (thus ensuring a ''stable'' population for The Sila).
