A female vampire who dresses like a jester. She is extremely skilled at turning to fog and subjugating humans and she is capable of controlling the thoughts and actions of those who inhale her while she is in fog form. She is weak against sunlight. Although Pirie is a vampireborn her powers are weak. She was persecuted by both humans and vampires because of that until Watt saved her and she made up her mind to gain power to help him. She dresses the way she does to make Watt smile. Although her heart does not beat she flushes when she gets angry perhaps because she is usually halffog. Likes cake and making marzipans.
