1For the last four decades, the Order of Nine Angles has offered its initiates a traditional system of occult and sinister training that is designed to create Adepts. This system, if correctly followed, brings the initiate into contact with acausal energies and entities that are outside the realm of mundane experience. This is not an easy process, and not for the faint of heart. This volume presents several of the texts related to pathworking and sinister esotericism from the Hostia volumes, and adds to it the entire Sinister Tarot of ONA's Christos Beest.
