The Pelath-Ri Marches, situated on the world of Voss, were located to the north of the mountain city of Voss-Ka. A significant portion of this area was submerged in water long before the Galactic War, but the indigenous Voss people ultimately constructed the Err-Ka Dam along the Marches' northeastern boundary to control the flooding. This forested region contained scattered remnants of both Jedi and Sith origin. Later, when the Gormak natives launched an invasion into the area, they commenced a large scale deforestation effort, erecting massive constructions, which led to the creation of the Clear-Cut Forest and the Barrenwoods. Voss commandos operated from several locations within the Marches, including Kri-Ta Outpost, Outpost Overseer, and Pelath Point.
