More than just waypoints in the shifting desert, seitches are the centers of economic and agricultural life in the valley. Carved into stone features that rise impressively out of the desert sands, Seitches gather and store moisture from the winds that blow from the west. These carefully crafted structures of immense size and complexity channel the wind into chambers to draw the moisture from the air. They also include complex waste distillation and reclamation systems. These caverns are maintained by the Hazir who dedicate themselves to the protection and health of the seitches.
The concentration of water makes the seitches centers of population. Small villages and towns are situated on and around seitches. Because of the water and shade growing foliage, seitches are waypoints for Nomads as they drive their herds accross the dunes.
The population of a seitch is lead by a head man or head woman. Typically the highest cast resident holds this position. The head person governs the day to day agricultural and economic life of the seitch. They do not have absolute power over the seitch. The Hazir is the final authority on the seitch. While primarily concerned with the health of the seitches water supply and plant life, they are also the spiritual leader of the the community since most seitch communities cannot support three specialized priests of the faith.
