Technically he can understand trolls and other mythical Norse monsters but that's not very relevant right now. "It's based on belief. The more your deeds become legend the more powerful you get. I don't know if it's possible to lose power if your deeds don't get repeated, since most of the pantheons don't have a lot of active worshipers." Something to ask at the conference of Scions when he gets back home.

Heavenly Courts... oh. He's heard of the Celestial Bureaucracy from a few people but it's probably different for this guy. "Logistics doesn't bother me all too much. I was usually the person who ended up arranging decedent pickups. Or sometimes driving them myself if I wasn't at school. Or handling billing for coffins, or scheduling viewings... but being a god is probably more complicated than even that." Not to mention that even if he did hit godhood he wouldn't outrank the older gods anyway.
