Nyimagon's eldest son, Lhachen Palgyigon, is believed to have conquered the regions to the north, including Ladakh and Rutog. After the death of Nyimagon, his kingdom was divided among his three sons, Palgyigon receiving Ladakh, Rutog, Thok Jalung and an area referred to as Demchok Karpo (a holy mountain near the present day Demchok village). The second son received Guge–Purang (called "Ngari Korsum") and the third son received Zanskar and Spiti (to the southwest of Ladakh). This three-way division of Nyimagon's empire was recognised as historic and remembered in the chronicles of all the three regions as a founding narrative.
