Argilon
Argilon: A demon said to serve the infernal ruler Astaroth. As a servant of Astaroth, Argilon wields all the same powers as his infernal master, including the ability to cause visions and to expound upon secret matters pertaining to the past, present, and future. Argilon's name appears in all four surviving manuscripts of the Sacred Magic of Abramelin the Mage.
