The Great Orrery is the name given to the Orrery at Firsthold. Its spheres are made up of genuine celestial minerals gathered by the Sun Birds of Alinor who traveled to Aetherius during the Merethic Era. The Sun Birds were eventually dissolved due to the untenable expenditures required to reach magic by magicka.
