Chaos Magic
This mini-supplement for Esoterica introduces Chaos magic, a post-modern Western magical practice rooted in occult traditions and developed in the 1970s. It explains how Chaos magic fits into the game’s Secret World and provides guidance for creating Adepts who follow this path. The supplement also includes examples of Chaos-flavored Mysteries and Soul Jars, along with ideas for incorporating its philosophies and practices into Esoterica games.
