I always thought the Daedric lore was really well flushed out and amazingly detailed, especially in Skyrim.
haven't played ESO yet (is very cheep) but it looks pretty cool ^^
i also love the Bosmer, out of all the races, I think they're the most eerie. I mean, ritualistic cannibalism? They're like reverse vegetarians xD
its even better considering how nice and polite they are in the game
