Orbanians derived from a Mesoamerican culture from Earth. Omeyocans transported them to Orban thousands of years ago via Crystal skull, where the people adapted to living in a non-tropical environment. At a one time the Goa'uld attempted to conquer Orban, but the Orbanians fought back and drove them away from Orban. In 1950, the Orbanians developed nanite technology. They began using nanites in their newborn children to increase their ability to learn large amounts of information, achieving adult levels of intelligence and maturity before even reaching puberty. The children who received the nanites became known as the Urrone.
