'You know the saying: Only and idiot looks directly at the sun. Now, just so you know, only the king of the land of the greatest idiots looks directly at the calerus in daylight.'

- Valkhor, local guide of Lumen, to a group of newcomers

Nestled at the border of the South Calerus, the town of Lumen sprung up many decades ago when the Empire decided to try and emulate the successful crystal harvesting operations of the Kalani people of the east. To date, the settlement is indeed the most successful such operation outside of Sargot Kala.

The Imperial word calerus has come to describe the many crystal forests that now dot the continent of Xeryn. The vast majority of these forests can be found in the east, in the province of Sargot Kala but some have grown in the central region of the Empire. Some caleri can be visited in the game, such as Loom, or the twin caleri simply called North Calerus and South Calerus.

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.
