The Orrineswa River was a river that lay near the Carrion Plateau and Mount Veermok, which was one of the holdings of the Tarkin family. Long before the birth of Jova Tarkin and his nephew Wilhuff Tarkin, a group of developers coveted the Tarkin family's holdings in the plateau and the surrounding territory. The Tarkin family attempted to resolve the matter peacefully and placate them with credits. They even offered to give the developers all the lands north of the Orrineswa River up to Mount Veermok but were rebuffed. In response, the Tarkin family lured the conglomerate to the bargaining table and assassinated them.
