Miradelgûn is a diverse region of forests, grassy plains, swampy canyon valleys, and highlands. It is bordered to the north by Cinazan and west by Grashakh. The south and eastern tracts of the region end at the Sands of Hell. The blistering sands of this desert snake along the south and then up the west.
In the southeastern corner of the region is a bay that was unnaturally formed from the anger of a god. In the Horgon Era, the god Poseidon was angered when a sect of Talos worshipers defeated his storm giant clergy at Hleirim. This anger resulted in the sinking of the city and the flooding of a section of the Sands of Hell. This flood of ocean water resulted in the creation of the bay Klo'nah Lomok. Today, this bay is commercial route for those seeking to reach the ports of the Toomrur Hegemony and the Mezrack mountain holds of Rethmorg.
Miradelgûn is largely a wild area with few major settlements. The two largest civilized areas are the lands under control of the Toomrur Hegemony and Rethmorg. With little success, the Khazarkar Empire and the Orchish Empire have tried to expand into this region.
The subterranean region directly beneath Miradelgûn is called Miryeril.
