From publisher blurb:
Deities & Demons offers a comprehensive overview of the various divine and demonic powers commonly worshipped in Ashlar and its surrounds. Herein, gathered together for the first time, are details of humanity’s major and minor powers along with a first look at the dwarven, elven, gnome, halfling and orcish pantheons and the fell, ancient powers of Amon-Pyr and Dagon.
This lavishly illustrated supplement is designed for use with the Duchy of Ashlar and the Gloamhold Campaign Guide, and is also compatible with The Lonely Coast.
