For Exalted 2nd Edition comes the fourth in the books of Sorcery, this time covering a plethora of spirits and elementals for use in your campaign. The first half of the book focuses on the terrestrial gods of Creation, with an overview of their function and society and statistics for more than thirty common types and specific deities.
The second half does a similar job for elementals, detailing their courts and a range of types from tiny nature spirits to the immense badass that is the Kukla. There is also a whole chapter for divine charms, allowing you to invent your own spirits, as well as for your Eclipse Solar/Moonshadow Abyssal to steal.
This is one of the better sourcebooks, with plenty of different and interesting antagonists and allies that will enrich any campaign; there's plenty of fun to be had just with a succession of traditional 'sorting out corrupt local gods' adventures. Cliche, maybe, but fun.
