Ahl at-Trab (Arabic: أهل التراب) are destructive beings said to live under the sands of the desert from the Muslim Tuareg folklore. They are rarely seen but are said to live underneath the uppermost layer of sand in the Saraha desert. It is said that these beings will drink dry the springs that the desert traveler needs for survival or trip up him or his camel as they pass. Some tribes say that these beings take the form of the columns of sand that appear in desert sandstorms.
