 It contains detailed information on the societies, cultures, myths, and deities of several non-human pantheons, including those of the elves, dwarves, gnomes, halflings, orcs, goblins, dragons, giants, drow, and many other creatures.Keith Eisenbeis suggests the book can be thematically divided in two, with the first encompassing typical player character races, and the second detailing "gods of the major intelligent societal creatures".The introduction sets out the theme of the book — non-human deities — and provides notes on using deities in a campaign, their common abilities, and how they are arranged in four tiers of power from Demigod up to Greater God.
