Really? How fascinating. You'll excuse me if I don't know what a vampire is. And you must accept my apologies, but I've always found human literature and myths to be a triteful dry and boring. Every story has to have a morally appeasing theme. There's no honor, no call to duty, no loyalty to the state. It's not a wonder the people of Earth are so placated. They've locked their demons in a closet and forgotten about them entirely.
I, on the other hand, am a Cardassian.
And if that doesn't strike fear into the hearts of humanoids then I must really be losing my touch...
