I've been skimming this thread so excuse me if this has already been mentioned, but has the nature of tempering been discussed? From the cutscene, I was unsure of whether Ifrit's tempering was of a sacrificial nature, or if one could choose to worship him if they were not an Amal'jah.
Also, Odin's roaming nature is another topic I'd like to discuss.
ALSO, could the tribe of deeper Noscea yet have a patron primal?
