The Remnant Holdouts sought to unite their countries and nations with the Resistance Pockets of the Remnant that was also scattered across the world.
The Remnant Holdouts later reunited with the Resistance and became the Ultranationalist Union of Republics after the United Republic Civil War had ended.
The Remnant Holdouts were built in Southern Africa, a small pocket of Western Africa and one country in East Africa along with the island of Japan, a country neighbor to China and another island in the Chinese sea.
