Studies of the Aerial Sphere

A Drankorian cosmological monograph series, written during the Drankorian Era, by members of the Occulta Ludum

Studies of the Aerial Sphere is a monograph series on travel in the Elemental Plane of Air, published by the Drankorian scholarly society known as the Occulta Ludum. Only three of a reported ten volumes survive in full, but the surviving volumes preserve first-hand accounts of falling, flight, wind currents, and navigation in the plane.
