What all lore did they [censored] up? I don't see the vampires as that messed up, and I've read all the in-game books about it, etc.
the only vampires with the ability to blend in with human society are the order (cyrodillic vampires, who, as the name suggests, are not in skyrim accoring to all knowledge), and the skyrim vampires are said to be beastial, paranoid, cruel, ice-dwelling monsters (a book from oblivion told about them being paranoid and living under ice [which they can reach through and grab their next meal] and all vampires are beasial and cruel [all but The Order]), that is pretty [censored] up lore if i do say so myself. they did not even get The Order right (which should not even exist in skyrim) according to the lore (these vampires are nobles, lord, and kings, not random bandits in the skyrim country side)
