Vampire means a lot of different things in different places. In my world, for instance, we've got three different kinds, all with different strengths and weaknesses and feeding preferences - include a whole Court that feeds on emotion/life force rather than blood. There are some who can only go out at night, and some who can turn into bats, and some who are competent sorcerors, and some who are violently allergic to garlic, and some who are driven back by symbols of faith, and some who think crucifixes are lovely, and...well, you get the idea. Different vampires in different worlds. So I guess what I was really asking is what kind of vampire are you?
And now I have another question, which is: what do you mean by vegetarian?
