I really like this because it allows you to expand on a concept that the game and show introduce, but never actually explain much.

I feel like the ambiguity allows people to establish their own lore to make things unique and fun for the individual party. I'll feel really weird if they suddenly release something that goes into the war, but the fact that there was one really makes me think about what could have happened during that time.
