From publisher blurb:
NOW IT'S TIME TO GO REALLY OLD SCHOOL!
Have you unleashed the mighty power of Divinities and Cults in your game yet?
Divinities and Cults: Volume III covers the gods and goddesses of both the Mesopotamian and Egyptian Pantheons, as well as a number of Evil Cults. Like Volumes I & II, this work provides detailed tenets, special cleric considerations, magical side-effects, numerous divine tests, and custom spell lists for all 19 of them. What is more, optional rules and random tables abound, organized by divinity of course. This excellent book is compatible with the various Old School Editions and their 'Retro-clones', especially Labyrinth Lord!
