I really think this should be a "gathering" class in-game. Lore junkies are rampant in Final Fantasy, moreso than any other game that's ever existed. To be able to collect data and lore on each of the astral and umbral eras as well as much of the info on this site would be immensely helpful to make it "official". Even the clarification about dragon speak was really awesome. I genuinely think people would go crazy learning about all of the lore of this game through items and quests.

Remember how this was done in Final Fantasy Tactics? Brilliant, absolutely brilliant.
