A role-playing game with the potential for the characters to become horrible and unspeakable Gods, using their weird forms of black magic to enter the human universe and change it forever! This is a Lovecraft inspired RPG where the players have a lot of control over the story and their characters. Contains a Color Sphere of Influence system that determines a character's personality, style, and spell domain. More than a dozen alien, demonic races - unique in the scifi/fantasy/horror genre. Innovative and dynamic mechanics for motivating characters to do evil and dark acts... also a new system called Story Alteration where players can directly influence the adventure's path.
