"Hailing from sunny Transylvania, your first blood-related incident was when you stabbed a servant girl in the face with a pair of scissors for underperforming. Some of the red spray landed on your hands, and as you washed it off, you noticed that it left your skin fresh and young looking. From then on you were convinced that the blood of young girls was the secret to eternal youth.
Rather than killing girls outright by stabbing them or slitting their throats, you enjoy torturing them for weeks on end by pricking them with needles or prodding with sharp spikes - all to bathe in their blood. You've killed over six hundred women, all without raising a peep from the authorities."
