A pretty wacky setting, but on the good side. Reminds me of Narcosa, that was also really weird and unusual.
As to the content we have a mix and match of classes, short descriptions of places and some tidbits of information of the titular Chaos Gods. Gamewise this is a semi-solid accessory, I would rather call it that. It's fun to use some elements of this setting in conjunction with elements from Narcosa and poof you've got some incredibly weird (but not gory) piece of setting. Drug dealing gnomes, hazy halflings with chaotic mellow alignment (yeah), totalled trolls and stoned snakes.
What's not to love?
