Also known as Logic or the Unchanging Queen, Sorcha is the Queen of the High Court. She is intrinsically linked to the other world of Faerie and as a result she cannot leave it; anywhere in the mortal world that she attempts to go is consumed by Faerie. Frequently, Marr describes Sorcha and Bananach as the engine that drives magic- they oppose, but one cannot exist without the other. To destroy either- though it does not seem possible- would create a domino effect that would eradicate all faeries everywhere.
