Pa'aal served as the primary satellite orbiting the planet N'zoth, which was located within the N'zoth system. It was considered a moon.
N'zoth's moon, Pa'aal, fell under the dominion of the Duskhan League. The Galactic Empire's construction of a base there, which then hosted the Black Sword Command, triggered an assault by the Yevethans. Following this attack, the Yevethans created a camp on the moon to imprison captured Imperials, forcing them into slave labor and holding them as prisoners of war.
