Reachmen are a race of humans closely related to Bretons. Despite their shared lineage, the Reachmen do not consider themselves Bretons, and the Bretons share this sentiment in turn. The Reachmen have their own distinct culture and society apart from the Bretons, and have lived primarily in the Reach for centuries. The Bretons of High Rock and Orcs of Orsinium often clash with the Reachmen, who claim the Western Reach and the Wrothgarian Mountains. The Nords, who have territorial claims in the Reach, have also had run-ins with the Reachmen. The Eastern Reach of Skyrim is controlled by the Reachmen, being independent from both Svargrim and Jorunn.
