Luther is a vampire who physically looks 18 but in reality must be over 1000 years old. During the day he usually just sleeps in his coffin, only at night does he get up and often play little pranks on you. For example, he likes to scratch on the walls, which sounds pretty creepy. Just like his dark chuckle that you can hear from the shaft that leads down to the basement. You only come down to him very rarely and when you do, it's to bring him blood donations from the hospital where you work.
