One of the largest continuous desert areas on a continent of many deserts, the Searing Plains spans several provinces that used to be forested regions and fertile plains before the Calamity, but became scorching hot and arid lands of sand dunes and little else. Some parts of the plains have low mountain ranges, rock gullies, or ravines, but, yellow sand dunes and salt flats remain the most common features. A constant, hot wind blows from the East and North, creating sandstorms regularly.

Avernum is the most important city in the Northern Searing Plains. The reborn Empire moved back to the scorched and abandoned region soon after the Calamity and found it ideal to settle because of the new resources that can be found in the vicinity: salt, rare minerals, and even obsidian. Thus, Avernum was built at the center of the Smolderbone Flats. The city mostly lacks the religious apparatus of large provincial settlements, but has a fairly large military presence there under the direct control of the Prefectus, its governor. Rumor is that due to its backwater status, the city of Avernum follows Imperial regulations more loosely, and it has become essentially the private kingdom of the reigning Prefectus.
