I do watch a lot of Supernatural. It's one of my favorite shows. But, it is fiction. And yes, the the sarcasm I made at the beginning of my last post was drawn from there.
I first read about them in Dion Fortune's book Sane Occultism. She states:
"Cases also occur wherein people volunteer to assist in some difficult and dangerous occult undertaking, such as the hunting of a black magician." (Page 179)
In another work, Psychic Self-Defense, she states:
"In addition to the Occult Police, who function solely on the Inner Planes, there also exist certain groups of occultists who have banded themselves together for the purpose of combating Black Occultism. I suppose they give themselves different names, but I do not know what these are; I have always heard them referred to generically as the Hunting Lodges. Upon various occasions I have skirmished on their flanks and looked on at some lively forays."
I have also read about them in the works of Dolores Ashcroft-Nowicki, but unfortunately those books are in my storage room and not available to me at the moment. I'll be happy to post them when I get them out.
As far as what I have read, I have studied the works of the Grand Grimoire, the Grimoire of Honorius, and the Theurgia Goetia, as well as several of the more modern works. But most of the new works are just reworks of the older ones.
I don't want to go through the list of things I have done, books I have read and what not. While I do enjoy works of fiction (Never liked Charmed much, although it does get the blood flowing. Lol!) I can insure you that I don't draw upon any fiction when discussing such things.
