Yep. Vampires find Werewolves (and other Lycanthropes) to be a delicacy, with their mix of human and beast blood. I do believe it was one of the books in Daggerfall that said it.
Precisely. "Vampires of Iliac Bay"
Couldn't vampires just feed on regular people? But anyway maybe Skyrim could be alittle unique and werewolves could work together with vampires.
Vampires feed on anything warm-blooded. Their preference is regular people though. I cannot see the vampires of Skyrim working with anynone for that long. We only know of the Volkihar, the vampires from Eastern Skyrim. We do not know if there are vampires in western Skyrim. But I know for a fact that the Volkihar is mentioned to be highy cruel and paranoid. They never venture into the world of men except to feed. I don't think they have any political plots of plans for "Tamriel domination". But we don't know that for sure until we see them or hear more about them.
I would enjoy seeing a werewolf tribe. Only twice was werewolves and Lycanthropes shown to work in packs. One mission in Daggerfall had vampires try to clear out a fort of Lycanthropes who had a leader(The alpha). And in Bloodmoon were werewolves were led by a single divine intevention(Hircine). Vampire's have problems with each other. Just about every province that has more than one vampire clan has them battling each other out. We saw this in Illiac Bay and Morrowind. We did not see this extensevely in Cyrodiil because the Order vampires wiped every other vampire clan off the face of Cyrodiil. Because they are just that badass. We did, however, see Janus Hassildor send the player to go and wipe out a barbaric group of vampires in Bloodcrust cavern. This is how the Cyrodilic clan operates. Notice he never actualy did it himself but he sent someone to do his dirty work. Read "Manifesto Cyrodiil Vampyrum" for more information on tenets of this clan. And the book itself suggestes the Cyrodilic vampires made Cyrodiil their home
as of the Third Era.Meaning they wiped out the rival clan that era or simply moved in and destroyed every competing vampire tribe. So since the Empire is crumbling, we may see them move to Skyrim to try and take over. Because they
"Ousted all other competitors, much like the Imperials themselves had done".
