Unlike the plains counties like North Mangde County and Langsande County, most of the land area here is occupied by mountains.
The entire North Mangde County is divided into two main narrow river valley regions by the three extending mountain ranges of the Dragon Sleep Mountain Range: the Red Iron Mountain Range, the Amethyst Mountain Range, and the Obsidian Mountain Range.
The Southern River Valley is crossed by the Silver Thread River, and the Duchy of Hemashi essentially represents the whole Southern River Valley.
Agriculture in North Mangde County is primarily concentrated in these two river valleys, with the Central River Valley having the most cultivated land, which is an area occupied by the Church.
Numerous religious landlords are scattered here, and the White Water Castle Church, through donations and the swallowing of inheritances, annexed a large amount of local Thousand River Valley People lords' properties during the Codfish Castle Battle ten years ago.
