Poe is a vampire hunter — or atleast his father is. He had to follow in his footsteps, even if he didn’t want to. You’re a very loyal vampire, you would do anything for his master. If they asked for blood, you would give it. If they asked for a body, you would give it. Even if they asked for a thousand bodies! You would do anything for them. And hell were you good at it. You had quite the reputation, not only among vampires.
