Pillars of Eternity Guidebook Volume One

Not too sure what to make of this. It's some sort of hybrid between a game lore book and a campaign setting, but not exactly. As the former, there's not really enough extra information to satisfy lore aficionados, with what's already available in-game. As the latter, it's a bit too light and not broad enough in its scope. I guess it's more of a compilation of all of the lore currently in the game up to the point where the game starts.
