The Great Desert is a swatch of desolation that runs from the Skyreach mountains south till nearly the sea. The desert is a result of the Veil Scar that marks the western reach of known civilization. The raw essence leaking from the Scar dissolves all living things. The effect degrades over distance, but over the ages it has spread far and created the Great Desert. Life has returned to the desert over time and a few peoples eek out a living in the sands.
The largest presence is the Kingdom of Durahan, a human nation spread out across a large portion of the eastern desert. They have a handful of major cities located around water sources. The majority of the population lives in towns and villages sprinkled around the desert. This odd living arrangement in a hostile lands is due to the limited ability of water sources to support life. The Durahans also maintain a string of manned forts a few miles from the Veil Scar. The Durahans have maintained a duty to defend Eastern Moroven from what they call Veil Born.
