Metopotamia

Metopotamia or "Land of Prosperity" is the name given for northeastern Scorpia. It corresponds to the Dorsair District of the country and is a massive valley protected by the Dur Mountains. It is considered the cradle of Leatixan civilization as the first early societies formed in the region. Ancient Age civilizations such as Metopotmia, Impera, Castile, and Duria all occupied these regions for well over a few hundred years, rapidly developing and creating a vast series of roads and cities.

The Metopotmians dominated the first few hundred years, until around -4894 when the Durians successfully sacked the central Metopotmian city of Asilia. From that point forward, Dur would continue to heavily control the region until their exile in -4881 when the Castilians removed them out of the region. From -4881 to -4728, Metopotamia lived under relative peace with strong Castiliean rule. It wasn't until Dur invaded that year did the region become controlled by the Durian Empire all the way to the +100s.

Metopotamia was home to the First Great Revival and the Second Great Civilization movements from around -5000 to -4700. These movements inspired an advance in Leatixan society, as well as promoting concepts that would be continued to develop under the Durian rule. Some of the most important stages of development such as mass agriculture, channeling rivers, development of sea capable vessels, and many other critical inventions were created in Metopotamia. Advancements in astronomy, chemistry, and mathematics also came out of the region, especially in Retin and Metopotmia.

Etymology
The term Metopotamia comes from the Durian root words of Meto for Prosperity and Amia: lands. Its first usage is seen in late -4700s writings by Durian military officials. The term has been used to describe not only the defined region, but also its mountains and parts of the New Lands. In modern usage the term is kept to only the area inside of the Retin Mountains.

Metopotamia can be divided into three district regions, split by the Hiu, Cader, and Xzen rivers. The Cader river is by far the largest of the three, dividing Southern and Northern Metopotamia. The Hiu bisects the Southern regions, creating a fertile valley first populated by the Ventils. In the northeast, the Xzen river divided the Imper subregion to the Castil region. Here, the Castilieans and Impers formed, developing a strong and dynamic society.
