Agaliarept: This demon appears in the Grand Grimoire and is named as a general of Hell. He is purported to command the Second Legion of Spirits for the glory of the emperor Lucifer and his Prime Minister, Lucifuge Rofocale. Agaliarept is a keeper of mysteries, and he is credited with the power to reveal any arcane or sublime secrets to the dutiful practitioner. Buer, Guison, and Botis, three beings traditionally included among the seventy-two demons of the Goetia, supposedly answer directly to him.
