Vampires and Werecreatures.... but mostly Vampires. I'm still hoping for the ability to turn at lest one NPC into a vampire follower. If you could turn 7-10 and have a coven that would be great, but vampires should look normal save some paleness unless they choose to use there powers, then they should look like the old Nosferatue movie. No to gimped vamp faces.
PLEASE DONT MAKE THEM LOOK LIKE NOSFERATUE!!!!!!!!! That is a horrible looking Vampire,looks so stupid.
this would be a cool way to look if you use your powers

and the more you feed the more vampirish you should look, and you should die if you go to long without feeding, unlike in Oblivion where the less you feed the more powerful you are (That makes absolutly no sense!). That would eb cool if you could get some of the powers the Blood Omen dude gets to.
that are just the cyrodill vampires every province has its own clan
i recomend you read this

I have heard of the vampires of Skyrim! I can just imagine a man walking on the ice and all of a sudden a cold icy hand comes up and pulls him through, or mabye behind him a mist comes up fromt he ice and a vampire forms from the mist. it sounds very cool. I love that book to, i remember the first time I read it, I was mezmerized.
