The EWOE does exist, and I know what it is. It was actually a lucky guess, but hey, I had it confirmed both in Gardner's writings and by some real Wiccans. Yay me. Also, it's not oathbound, but I'm not spreading it around since it's such a good test for whether or not you're talking to a fluff. Yes, I realize I sound like a fluff myself for being all "I know something and I'm not going to tell you what it is... nyeah nyeah" about it, but it's in Gardner's writings, you can look it up yourself if you're that curious. ^_^
As a sidenote, we might be seeing some fluffballs in here pretty soon, as I've been directing them to this thread. Get your ignorance-seeking tactical weapons out, minions!
