Index
All in all an extremely classy book. There's more info here than you can absorb in a straight reading. Personally I will use it as a resource guide for my existing pantheon(s) rather than directly integrating it into my campaign. Don't let the $40 sticker price scare you - you get what you pay for.
More to come if there's any interest.
