The desert in the west of the Jagd Yensa. Fine sand beats in waves against the feet of the rolling dunes of this region which, together with the Ogir-Yensa Sandsea, is called the Great Yensan Sandsea. To the west of the Nam-Yensa lies the gorge known as the Valley of the Dead, so called because it has been the scene of many an ill-starred adventurer's demise.
