Imperial Theosophy teaches us that our world was born from magicka, the creative force that informs and sustains all life. The sources of magic are the many and diverse heaves beyond the void, collectively known as the Aetherius.
Aetherius, ancestral seat of the Nine Divines and the other original spirits, is the plane of pure magicka. Whereas Oblivion may surround us every night, it is aetherial energy that infuses our daily existence, from highest to lowest, and gives all the races of men, mer, and beast common purpose. Its magic brings the rain to the fields, love to our hearths, and scientific principles to our technological industries. It gives us the very Sun itself. Finally, Aetherius is the home to the Aedra, those cornerstones of the Mundus whose aspects we see in the temple, in lordship, and the high walk of heroes.
Visit to Aetherius occur even less frequently than to Oblivion, for the void is a long expanse and only the stars offer portal for aetherial travel, or the judicious use of magic. The expeditions of the Reman Dynasty and the Sun Birds of Alinor are the most famous attempts in our histories, and it is a cosmic irony that both of them were eventually dissolved for the same reason: the untenable expenditures required to reach magic by magicka. Their only legacy is the Royal Imperial Mananauts of the Elder Council and the great Orrery at Firsthold, whose spheres are made up of genuine celestial mineral gathered by travelers during the Merethic Era.
