Dark Sun: The Scorched World of Athas
Great Alluvial Sand Wastes
A wide belt of dunes stretches hundreds of miles from Urik all the way south past Altaruk, paralleling the Ringing Mountains. Over the ages, sand washed from the mouths of mountain canyons has accumulated into a vast desert known as the Great Alluvial Sand Wastes. This region walls off Tyr and the foothills of the Ringing Mountains from the rest of the Tablelands (and the Tyr Region in general). Although the terrain is difficult to travel, it is not especially harsh, and tiny wells and oases lie scattered across its golden expanse.
