The third member of the Shadow Council; a preternatural. This advisor to Queen Victoria is meant to break the stalemate between the potentate and the dewan. He or she represents the voice of the modern age, as opposed to the other two older, set-in-their-ways advisors.
It is also implied that the muhjah would oversee any and all affairs related to preternaturals within the kingdom, as the potentate oversees vampires and the dewan does werewolves. However, this aspect does not appear in the books, as only five preternaturals exist within Britain, they become physically ill in the presence of one another, and prefer to keep a low profile.
