So, I'm very interested in religion-oriented characters, so I've been eagerly reading up the material on the setting deities (such as "Inner Sea Gods"). However, I've found myself a little confused as to what seems to be a rules inconsistency.
Mainly I noticed some discrepancy between material in Inner Sea Gods and Pathfinder Player Companion: Champions of Purity with regards to subdomains. Champions of Purity introduced a number of subdomains and associated deities. For example, the Revelry subdomain it associated with Cayden Cailean, and the Cooperation subdomain with Erastil. These subdomains (but not others, such as Redemption and Imagination) reappear in Inner Sea Gods, but they aren't part of those deities' portfolios...
Am I overthinking this? Sorry if this seems like a dumb question.
