Thumper (Horkos) Marjorie Splitfoot Forge is a Gardnerian High Priest, an initiate of the Minoan Brotherhood, a Discordian Episkopos, a recovering alcoholic, and a notary public from Houston, Texas. His first book, Virgo Witch: Divining the Details, co-authored with Ivo Dominguez, Jr., was released by Llewellyn Publications in November 2023 (and is available for here). His latest book, The Chaos Apple: Magic and Discordianism for the Postmodern Witch, will be released by Llewellyn in November 2025.

By day, he manages a leather and fetishwear shop, and by night, he dabbles in chaos magic, offers geomantic and lithomantic readings, and blogs irreverently. His essays have previously appeared in The Gorgon’s Guide to Magical Resistance (Revelore Press, 2022) and Modern Witchcraft with the Greek Gods: History, Insights & Magickal Practice (Llewellyn Publications, 2022).
