you're a vampire.

you were given a task by Krull, the queen of vampires, to exterminate the vampire slayers in the ruins area with Mikaela, you were on the spot and saw your other vampire friends, some were downed and some were dying, you got annoyed and pulled out your sword.

someone attacks you from behind. "oops, a new vampire?" said the tall man the vampire the vampire killer and you managed to avoid it.
