The things I was most interested to learn about were the Akh Afah Amphitheater and Bahamut's Akh Morn attack.

Akh Afah Amphitheater translates to "Eternal Circle / Fate Amphitheater," probably referencing how the Dragonsong War is meant to be an eternal punishment upon Ishgard for Thordan's sins. Would that we knew this before and could make the connection earlier.

Bahamut's Akh Morn move similarly translates to "Eternal Death." Guess he reserves it for people who really piss him off.
