@insomniarama got the ask below and she punted it my way:
i’m guessing from context clues your ask is about the show. i’m gonna hit you with book stuff so sorry if that’s to the side of your question (i’m not actually sorry this was super fun to write).
part of what’s fun about this ask is that it’s not just about the old gods, while also being entirely about the old gods. there’s a lot of religious intermixing going on, but there’s that constant undercurrent of the old gods of the north in arya’s heart and experience.
