Massive dust & sandstorms are reoccurring elements in both fantasy and science fiction worlds, though they can be found in other world types as well. When designing such storms, consider how long they last and how intense they may be. The people who live near such storms may have found ways to protect themselves from the worst of these weather events, utilizing subterranean spaces, bunkers, or fortified indoor habitats. They may have gear that allow them to survive or navigate the storm. Normal equipment may fail under such conditions and long-distance communication may be disrupted.
