Human Major Race (Homo sapiens zhdotlas) inhabiting the Zhodani Consulate, a region far spinward of the Imperium. The Zhodani Consulate rules a sphere approximately 70 parsecs in diameter immediately to corespinward of the Imperium, believed to include in excess of 80% of all racial Zhodani. Much of the remainder inhabits the Zhodani client states, although other sub-species of humaniti are also to be found in the client states and the consulate.
They are a sub-species of humans that evolved at the edge of the galaxy. They keep tight control over their population through key use of psionics, which are discouraged by other human empires.
