Aerotheurgy is a set of ancient elven magical practices that involve levitation and the manipulation of airborne objects. Most notably, skilled aerotheurges were responsible for raising and flying the aeroliths. Many of the Kingdom of Eita's greatest monuments were constructed through significant use of aerotheurgy.
Today, the details of the practice of aerotheurgy are almost entirely forgotten. Even in the era of the aeroliths, the reclusive and cloistered master aerotheurges were extremely reticent to allow their knowledge to spread beyond their chosen apprentices. Interest in the secrets of aerotheurgy began to falter over time, especially as the practitioners of this magic spent almost all their lives in the depths of the cities ensuring they remained in the air. Apprentices became fewer in number, and the masters of the magical art were not replaced. The aging aerotheurges of the four remaining aeroliths are the only individuals alive who retain knowledge about this form of magic.
Despite attempts by well-trained and educated mages around the world, only fragments of the theoretical underpinnings behind aerotheurgy have been independently rediscovered, most notably by the scholars of Sharruma.
