looking at the list of variants, not all of them match the core domains or the subdomains from the APG. Why not? i can understand creating some new ones for players to use in there own 'worlds' but at a minimum the domains from the PFCRB and APG should be covered. theres a battle variant but not a war. is there eratta out there that covers this?
Instead of looking at the domains, take a look at the deities' portfolios (similar, but not quite the same).
Cayden Cailean, for example, has freedom, ale, wine, and bravery as his portfolio. See page 43 of the Pathfinder Core Rulebook.
