Magical evocation is one of the most fascinating yet misunderstood practices in the occult world. The idea of calling forth a spirit from another plane to visible appearance, and of consequently commanding it to perform some deed, has fascinated occultists since at least the beginning of written history, and most likely before. But why the fascination? Ask anyone who has read a grimoire such as the Goetia or the Necronomicon and they'll tell you why. These books promise great power and wealth to the would-be evoker.
