What is "agaliarept"

In the Grimoirium Verum, Agaliarept is purported to be one of two demons directly under Lucifer; Satanachia being the other. The Grimoirium Verum also states that Agalierept and Tarihimal are the rulers of Elelogap, who in turn governs matters connected with water. The Grand Grimoire holds that Agaliarept is a general with the power to uncover secrets and reveal mysteries, and commands the second legion (including Guer, Gusoyn, and Boris).
