Atlantis: Beloved Jewel is the third novel in the Atlantis trilogy begun in Atlantis: Precious Stone and continued in Atlantis: Cherished Gem. As the sequel terminated, the Atlanteans in their insular Lens had accidentally and prematurely propelled the themselves into the innovative Fifth Qabalistic World of Mazohir, thereby apparently having failed in their goal of inspiring the Terrans' awareness of the existence of the Lens with its cache of immortalizing AurLplasm. Additionally, they had departed the Fourth World of Assiyah sans having transported the Physical Cosmos with them into the luminous eternal realm of Mazohir. Thus, the Magnum Opus from the Diamond Temple at Avalyn in Mazohir is necessarily concerned with reparations, end-time, and the Act of Allural. Radical alterations, however, are required of the Diamond Class Aspirants as the new term commences at the Temple, changes that shatter their esoteric associations and their romantic and erotic involvements. Lynci, Tym, and their classmates find their friendships and relationships changed drastically by the unsettling new order. Yet, despite the disruptions, the newly initiated Intermediate Adepts are required to perform ever more arcane Magick, both Ascendant and Descendant, in their efforts to manifest AuL's desires for his dual Creations.
