Deral-Khôr was the largest river of northern Bellakar and virtually separated Mardruak from Felaya.It had once been a far greater river running all across the Dune Sea from the southwestern Ered Harmal into the Belegaer but it had run dry for most of it's old course and only it's mouths and some smaller tributaries in the Hills of Bellakar continued to carry water.Still in the rare periods of rain all few centuries great floods would appear and revive the older river for a very short time.
