I like how tidbits of lore from the game keep proving relevant in some way, yet guys who are good at game mechanics and tactics seem to be as or more aware of that aspect of the game than everybody else, which is one of the few things that doesn't quite match my experience with MMOs - generally, people who do high-level content don't seem to concern themselves too much with the minutia of the lore.
With no resources like a wiki or some collector's edition book about it, I'd expect that knowledge about the subtleties of NPC society, mythology and whatnot to be better known by players not quite with Shiroe's focus, who might serve as counsel on those matters - then again, now Shiroe has that NPC scholar for that...
