A Haruspex is a faerie who deals in mystic matters, practicing the arts of haruspexy. Unlike the Mimas, who are spiritual leaders, a Haruspex deals with the dark arts and have a connection to the ancient ways of the fae. They are practioners of magic, are powerful seers and have a deep knowledge of mystical rites. Haruspexes also make potions.[1]
Aoife Tsigani was the most prominent Haruspex in The Burgue, maintaining The Apothecary on Carnival Row.[1]
