The Mirrorwide Flats are broad salt basins and dry lakebeds broken by low crust ridges and the occasional black rock island. The ground ranges from hard, polished salt you can cross at speed to soft crust that hides brine mud; after rare storms, shallow sheets of water turn the surface into a true mirror and strand anyone without raised wheels or wide feet. Winds drive white dust squalls that burn eyes and foul gears. Landmarks are scarce and heat haze doubles distances, so travel relies on cairns, sun-compass, and night stars.
Water is unreliable and usually unsafe without boiling; wells tap brackish pockets along the margins. Tiefling oath-roads skirt the basin edges and post “no drain” marks at the few seep springs. Rail lines cross on elevated berms with spaced refuges; breakdowns here are serious. Resources include salt, nitrates, and rare crust blooms used for reagents. Common hazards: mirage routes, crust collapse, corrosive dust in mechanisms, and sudden weather that turns a day’s march into a trap.
