There are no vampires left, as they ran out of tasty virgins to feast on.
Oh, they are still around, though misunderstood. They could always go out in the day, they just preferred the night. And they don't drink blood. They prey on underage children, usually at night. Some of the children become infected with hate, ignorance, and racism. They in turn grow up to infect yet more.
Recently, they have grown in numbers to the point where they are running for political office. They also control several large media outlets.
Now, where is that kit?
