It does bother me that the Bosmer race were ( are ) written to have been know to cannibals. I am hopping that it wasn't the whole the race of wood elves or that it was fasleiy written by historians.
Nah, that's definitely a thing, but usually only in Valenwood itself, since it's not allowed by their religion to eat Valenwood plant matter. Although according to TESO devs it's considered a very private, personal and spiritual matter. They only eat people in public during the Wild Hunt, and when they do that they aren't even completely Bosmer anymore.
And I'm glad they're this way. It's more interesting, and the worst thing a fantasy can be is boring.
