Interesting very interesting, I pestered my fiancee with this question because me and a few co-workers were debating LOL!
At work is boiled down to whether he was a Zombie or a Undead, if he was undead then it was basically through some kind demonic possession, but then I argues what about the Resident Evil theory, like say a virus or something like that, or maybe some kind of parasite.
As for the Dracula I dunno, I think his was due to a ritual and blood sacrifice
My fiance contends that she loves me, but who cares, and I said if she got bitten by Dracula she would care.

Ok Gotcha, see that is what I thought, what the hell does High-borne mean in relation to this, are Vampires a cast system or something?
That would explain a lot about why Nightelves have Vampire teeth
WAIT...
Nightborne don't have the vampire teeth but Nightelves do, WTF!
