The Eastern Province is one of the five provinces of the United Island, located in the eastern region of the country. It is the third largest province by area. The borders of the Eastern Province were drawn up on December 19, 2016, when the United Island was founded during the First Continental Congress. Horseland serves as the provincial capital.


Most of the Eastern Province is covered by the Great Eastern Plains, a vast expanse of flat grassland with a few meandering rivers throughout. The province is bounded to the east by the Federal District, to the west by the Delta and Forest provinces along the Euphrates River, and the Ocean to the north and south. A large peninsula extends from the mainland in the south, which contains tribal land belonging to the NPC villagers of Brownfeather.
