Desert (range)

Deserts are regions where little precipitation produces hostile living conditions for plant and animal life. The lack of vegetation exposes the unprotected surface, intensifying weathering processes through wind and temperature changes from day to night. Resulting fragments are scattered, collecting into dust storms, level sheets of sand or piled high in billowing sand dunes. In other parts, small particles are blown away, leavking shattered mosaics of smooth or sharp stones, forming pavements a hundred miles wide.

Plants and animals living in the desert need special adaptations to survive. Many of the monsters that dwell in the desert are the sort that have no need of food, or which may travel hundreds of miles in a day, in order to obtain it. Humanoids surviving in the desert cluster around areas where water can be drawn up from below ground or collects on the surface. This water is often harsh to taste and smell, but will nevertheless sustain life.

The desert is productive in some degree, as the exposed rock reveals places where valuable minerals such as ores, salt, rare minerals and gems can be obtained. Additionally, plants growing in the desert provide rare materials such as incense and natural resins, both of which cannot be found anywhere else. These goods are exported out of the desert by caravans of camels. As deserts are large geographic obstructions between civilizations, tenuous trade routes are forged, enabling goods from one climate or culture can be exchanged with another.

Some arid lands that are thought of deserts are more properly thought of as barrens, as these regions possess short grasses and extensive areas of scrub brush.
