Taking nearly 600 years to build, this massive 696,731.46 km toroidal superstructure forms an artificial ring around the planet Jupiter. The interior of the torrid forms the downward floor while the exterior has large sections of clear Axial Alloy that lets in sunlight for crops and other bio-organic processes. The structure was sparsely populated, with less than 9 billion people, mostly clustering around a few large megacities. Designed and constructed during the 6thmillennium by the Status Forward AI Hive, it housed humanity for nearly 1,000 years.
