Gravity manipulation is the physical modification of gravity by something or someone. Zenolians and Harbians are the most renowned for using gravity manipulation, as they both use it to large scales. The Zenolians first invented gravity manipulation to help construct buildings such as Abaddon and Aetherwrath. Since they are in a stable environment, they do not have to use gravity manipulation for anything else. Harbians, however, discovered gravity manipulation many millenia later and quickly used it to keep the Harbitros Nebula's inner-orbits stable.
