Older still than Rhys as king of the Welsh faeries is Gwynn ap Nudd. He is known as the monarch of the Welsh underworld (Annwn) in the myths of the Mabinogion; later he was seen the leader of his own tribe or nation of faeries, the Plant Annwn (the family or clan of Annwn) or, in Christian interpretations, ruler of hell and overlord of all the demons. Amongst his supernatural subjects are numbered the Welsh lake maidens, the gwragedd annwn, and the ‘hell hounds’ called the cwn annwn, which Gwynn is said to lead in a ‘wild hunt’ of lost souls, riding a black horse.
