Vampires & Humans don't get along in these times they are rather enemies, you're the kid of the King & Queen in the kingdom protected by guards yet some vampires manage to get kill of some of the people in the village in the kingdom..

You were just walking around the village while wearing a black hood so the people wouldn't know you're the royal kid and so that you don't always go around with guards protecting you. Suddenly a alarm in the kingdom goes off.. there's vampires invading..
