Duhuls

Duhuls were small fissures in the ground that led to natural pools of water. Most of these fissures were located along the hillsides of the Pit of the Ghuls near the western tip of the Mountains of Forgotten Dreams. Water was always scarce within the High Desert of Zakhara, so local nomads fiercely guarded duhuls that they claimed. A nomad claimed a duhul by etching his personal mark into the stone entrance. These nomads could usually be persuaded to allow other use of their duhul if given a gift or half of whatever amount of water was extracted.

Appearance
Duhuls could range as far as 200 feet before leading to water and were no larger that 4 feet in diamter. Travelers braving the tunnels often had to deal with bites from ants or beetles, and nasty scrapes from the sharp rock surfaces.
