Thlayli, there does not need to be unity between the multiple races, within a race though, there could possibly be unity.
You don't understand at all.
I'm saying that 25 different creation myths with 25 different gods seriously implies that within the setting the gods are not real. Since not
all of the monotheistic faiths can be correct that their god was the one that created the universe. And if the gods aren't real, they don't really matter.
By acknowledging some of each others gods in some fashion, we acknowledge some vague, but related divine tapestry which created the universe. The gods
are real, not simply stories, but we differ on the interpretations. I'm obviously not calling for true theological unity between all players mythologies, not at all. What I am
hoping for is more efforts at cooperation.
And why, exactly, should there be unity among races but not between races? That's an extremely arbitrary thing for you to argue. Men and elves believing in the same god, or elves worshiping different gods, is interesting.
Also, most players have looked to one god, because that's easy and familiar. By embracing a pantheon, I can reach out to other players and have connections to their mythoses, even if that connection is "Oh my, the god you worship isn't good at all, he's a bloodthirsty monster!" because that creates an interesting story.
Do you understand how that could be useful or important to the setting?
