Looking for a reference or where to go
I have been reading through the manual of the planes and I'm wondering in Greyhawk or ADND mythos/cosmology - where do the evil gods live and what are the relationships to the Arch Devils and Demon Princes?
Do Lawful evil gods live in hell, but next door to Asmodeus? Who is more powerful?
Does an Arch Devil worship or report to an evil god?
For my campaign, I will probably have the Arch Devils and Demon Princes be the evil gods, but I want to understand how Gary or ADND was thinking these were supposed to work together?
Gary wrote a little about this in Dragons #64, 71, 92, and 96 (but 64 and 96 are most on-target, I think). The Gord novels also offer some insight too; see Krista Siren's page at https://greyhawkonline.com/gordmain/ for summary details.
Changing up the gods and their home planes, and defining their relationships with devils, demons, et al, is important to putting your own stamp on the setting, and definitely worth thinking about.
