Yaciatal: One of four demons who can empower the Ring of the Sun. The construction of this potent talisman requires animal sacrifice. The finished item is reputed to grant its wielder the power to bind tongues. It can also summon a demon in the form of a great black horse. This infernal steed will convey its master speedily to any destination.
Yaciatal is one of the demons invoked to aid in the construction of this item. He appears in the fifteenth-century magickal manual Liber de Angelis.
