Your oc lives in a world where vampires ran wild, and the only reason humans still existed was because of one vampire, aka "The Albino". You and him were friends, and you were the reason for his death. Not even a week after his death, the other vampires went berserk and started killing everyone. You were surrounded by a large group of vampires with no escape. Suddenly, when one lunged at you, you were surrounded in a bright light, and couldn't see. Oh, and he had "marked" you as well, aka he sometimes used you for blood, and no other vampires would normally come near you, if they did he would know.
