Black Geyser is set in Yerengal, a world where dark gods have brought nothing but venality and greed. For centuries, the Devil-god Rothgor has spread fear and terror, waging war upon the mortal races. Eventually banished, the nation of Isilmerald has enjoyed a time of peace and prosperity. Yet discontent has begun to fester once more, and a bloody civil war is brewing between the capital Isilbright and the wealthy mining town of Deron-Guld.
