religion, but no religious wars... have you ever heard anything more naive?

I believe that holy wars will not be promoted by the AoC directly, the good gods the 7 gods have would not fight directly among themselves. The rivalry that exists is between the pantheon VS others.
Unless a player wants to invent rivalries between good gods 🙃

As others have said, there is no excrutiating need for it to be included as a system. Most players will still be able to somehow roleplay into it some way or another.

However, some time ago, on a thread about ideas for node policies, I made a suggestion that Divine Nodes mayors/Popes, should have a choice to enact a policy which reduces or nullifies Corruption for killing players of a different religion that the primary one of said Node.

Of course said policy would only affect the immediate ZOI of that Node (and maybe its vassal Nodes? more infor and testing required on that one).

But, any Node can declare a Node War against another Node. So the active ruler of a Divine Node could just roleplay the reasoning for said war to be over religious shenanigans. Probably doesn't even have to be a war against a different deity's Node. Could even be roleplayed as a difference of opinions on the same deity's theology. Just ask the Catholic and the Cathars during the Albigensian Crusade.
