The operations of magic and witchcraft deal with the hidden worlds of spirit and the powers innate within the natural world. The "Old One", who in folk tradition is often named "The Devil", embodies the rend in the veil between the worlds of the material and spiritual; the revealed and the hidden. It is through union with this entity that the witch awakened their powers and gained access to those residing within the hidden realms and the natural world.
From this wellspring of inspiration, The Devil's Dozen, a modern gramarye or black book of rites has been created and is offered by a present-day initiate of the Old Craft. Within its pages there are to be found thirteen rites of vision, sacred compact, dedication, initiation, consecration, empowerment, protection, illumination, union, transformation and devotion.
