Uma, or Uma Prime, is a city-state of the Esmeraldan Empire located in what was once Western Africa, on the Ivory Coast. The city is the capital of Datu. It is sometimes referred to as Uma Prime to distinguish it from the rest of the Uman/Datun region.
The city is subterranean and built four kilometers below the Earth's surface, just above the Earth's mantle, and exists entirely underground.
The city was founded by the survivors of the Advenan War in 4437. It was forced to join the Esmeraldan Empire in 4998 following a short military occupation.
