Black Streams: Cults of Ruin
A free fantasy roleplaying supplement detailing five sinister cults and their foul beliefs, including the devotees of the Black Emperor, the slaves of the Hell Kings, and other strange faiths. It provides guidelines for incorporating these sects and secret cabals into a campaign, whether using the Sunset Isles setting or adapting the material for another world. The supplement also introduces the Azure Inquisitor, a Labyrinth Lord-compatible character class devoted to uncovering and destroying vile cults.
