@Alectai How antagonistic will the new gods be of each other?
I could see a good argument why the new pantheon would work together in a more cohesive way (for one thing, you can't Protect something if there isn't something there to Protect in the first place, so Life spreading also means more Protecting).
But I'm unsure if the followers of one god are also able to offer prayers to another god when the need arises, without it starving the other.
