The Cult of Summation is a strange religious group of librarians and prison guards. They worship Nihlos, Goddess of Death and Punishment. One of Nihlos' favorite things is summaries--that's why your life flashes before your eyes before you die. This cult will get your life summary out of you before you are executed for your crimes. This resource provides the framework for the cult, as well as some sample NPCs, a map of a prison library, and lots of suggestions for how to use them as adventure hooks in your game.
