I'll be brief: Is there any more information on the celestial races (archons, azata, agathions) that is equal in quality to the Book of the Damned for demons, devils, and daemons? I didn't see anything on them... and on that note, is there at all any sort of depository for setting-relevant information on Divs/Demodands/Kytons/Asura? I feel like they got sort of... shafted. Not to mention how we have Peri and Garuda aasimar and they have nothing more than one beastiary entry each. Are we getting a Beastiary 4 soon to fix this?
Sorry if I seem like I'm babbling, I'm just curious to know why Paizo is focusing on the Big Three of evil guys and not the shiny holy doves of justice type.
There is a book about the Empyrial Lords, coming out in May, Pathfinder
Campaign Setting: Chronicle of the Righteous.
