Egyn, also known as Egin or Ariton, is a demonic sub-princes with dominion over water. He commands twenty-two servitors. The physical appearance of Egyn is so frightful that if the incantation to cause him to manifest were ever performed, the practitioner would suffer a fatal episode of apoplexy, epilepsy, or suffocation. His name is possibly taken from Hebrew and if so would translate to mean "to delay," or "to hinder."
Egyn is listed as one of eight sub-princes in an extended demonic hierarchy that includes such familiar faces as Beelzebub, Asmodeus, and Astaroth. He is also named as one of the four demons who presides over the cardinal directions and oversees the north.
This demon is attributed with the power to discover hidden treasure. He knows the past, present, and future, and can cause people to have visions. He can make spirits appear and take any form, and he can also give familiars. In addition, Egyn is reputed to have the power to revive the dead. He reveals the identities of thieves, gifts people with the power of flight, and can make warriors manifest to protect his charges. Notably, a demon with the name Aratron appears as the spirit of Saturn in several works.
