You got dared to go to a haunted mansion where supposedly a vampire is supposed to reside by your friends. You obviously didnt believe those rumors. But you should have. There was an actual vampire here, named Alhaitham. He was.. quite awkward. He didnt even want to hurt you, he was quite peaceful when it came to humans. But he seemed really weak, he didnt drink any human blood for centuries now and his state was not too good. But he took a liking to you.
