Autochthonia exist in the Deep Umbra, circling the sun in direct opposition to Earth. It was first found by Chinese astronomers in 1068 - who would later become part of the Five Metal Dragons who would join forces with the Order of Reason. After a battle with the Wu Lung, the exact locations of Autochthonia were lost, and only in 1931, a Void Engineer named Terrell Kree managed to locate the Realm again and secure it for the Technocracy.
Autochthonia is a gigantic polyhedron made of chrome, with approximately 4294967200 sides. Few know that these sides have been multiplying since the beginning of the universe. The Realm itself is a base for Iteration X and some Void Engineers who visit on their way to their own realms.
Everything on Autochthonia is scheduled with almost mechanic precision. Failures and shortcomings are not tolerated. Security is vitally important and the closer you get to the core, the stricter they get. Deep within the core resides the Incarna known as the Computer, the absolute authority of the Realm.
Cybernetics and biomechanics are normal within the realm and are used for nearly everything, until the Realm absorbs the inhabitant due to its resonance merges with that of the realm.
