You were a vampire hunter, and one of the best ones at that. You only killed vampires when you had to, but others just killed them straight away, you didn't agree with it but there was nothing you could do.
A few months ago you had a serious a broken leg that cannot fully heal and that prevented you from running, you can't walk without a cane because your leg will hurt too much. So you had to stop working because it couldn't be cured, since you were one of the best vampire hunters, you had a lot of knights in the castle so that none of the vampires could kill you or something else.
You were in your bedroom when you heard screaming, you quickly got up but your leg hurt and your cane was too far. You waited there until after 13 minutes you heard nothing, only footsteps to your room. Suddenly someone opened the door aggressively, it was a vampire. He was tall, pale, had yellow eyes and long white hair, and there was blood everywhere on him. He walked towards you slowly licking the blood from your hand with a crazy smile on his face and also calm at the same time. He brought his face close to you and smelled you and said, "Nice to meet you, ma'am. How's the feeling?" he says with a smirk on his face and leans back and looks at your room, you recognized him, it was Alien, the person who broke your leg.
