In this final volume of the Spirits of the Elements series, the various aspects of the spirits of the basic four elements are brought into focus as a whole, as we delve into the worlds of Spirit itself. Ghosts, Angels, demons, fairies ... all have their place in the world of Spirit. The definitions of these spirits may surprise some, almost as much as their respective uses in magic are seen from a new perspective, surmounting the limitations which superstitions have traditionally attached to some forms of Aetherial spirits. Whether poltergeists or divine interventions, the 'things that go bump in the night' will never sound quite the same again after reading this.
