The Esoteric Track at DarkoverCon was established more than 10 years ago to give an opportunity for people to talk about the "real-world" religions and techniques behind magick and energy work in SF and Fantasy. Ecumenicon and the Order of St. Michael have shared responsibility for this program and always offer classes from several religious perspectives. The theme of DarkoverCon 35 this year is Diversity.
