I think it's especially interesting that in XIV there will also be saints as well as gods. It seems a bit more Roman-Catholic that way, but could add some depth to those that choose to RP religious elements in to their characters. While I'm waiting on more lore before I decide how much/if any religion my character will have, I could definitely see her referring to saints in passing, or swearing by a particular saint's name.
