Sullivan County

Sullivan County is one of Picketralia's ten counties, and the second to least most populous, with a population estimate of only 5 people. It is bounded to the north by the Birch River to the west by Picketralia's national border, to the east by the Stimpton Delta and to the south by Hayes County. It is named for the Sullivan River, which runs near to the county. It does not have any towns or settlements, and it's population comes entirely from Outpost Island, a Picketralian military installation.

It was established in 1373 under the Counties Act. It's county seat is Stimpton, as there are no actual towns within the county.
