The Native Eriksons were the people who moved from Asia to Erikson in 30,000 BC. They are considered the original settlers of the continent. When the Vinlanders settled there, they mostly left the Native Eriksons alone, except for the Wars of Federation. In the Vinlandic-Inuit War, the Vinlanders gave the Native Eriksons their own country (UCI).
When the Castillians settled Ansuro, they left the Inca alone after hearing of the Inuit war.
