The history of Desdursy was very old, and they were recognized for being the first people of Tyran speech that dropped out the nomadism and settled on the eastern shore of the Gulf of Ûtum after realizing the significant amount of natural resources that the land offered. In addition, the Desdursy differed from their other cousins of Tyr offspring, because through their veins ran Númenórean blood of the Udahir, a people descended from the Númenóreans who had explored the waters and lands of northern Endor during the Second Age.
