The Rietic Mountains are a mountain range on the eastern half of Soltenna, spanning 2,000 km (1,200 mi) across four countries: Kadya, Lugida, Liosol and Yerlan. It was formed from around 90 million years ago partly through collision between the West Soltennan and Rietic tectonic plates and in other parts through subduction between Soltennan and Akulanen plates. The border between Kadya and both Lugida and Yerlan follow parts of the mountain range. At 5,480 metres (17,980 ft) above sea level, Mount Lenthir is the highest mountain in the Rietic Mountains.

Etymology

The word Rietic derives from the Ancient Riyan word rhéitwi "jade" through its Lithian rendition riet. Historically more expensive and rarer than gold, jade was a recurring element in imperial regalia during dynastic era Soltenna. The Rietic Mountains had been a famed source of jade at the time, hence the name. The Rietic ethnolinguistic group takes its name from the mountain range.

Orogeny and geology

The Rietic orogeny began with the collision between the West Soltennan Plate and the Rietic Plate approximately 90 million years ago. Initially both plates collided to form a faultline along its convergent boundary. The Rietic Plate would slide southwards along with the larger Mirarian Plate. As the Akulanen Plate broke off from the Baredinan Plate, it began to move northwest at high velocity against the Rietic Plate while opening the Gulf of Sharkunen. Rocks along the Rietic faultline were in turn forced upward and the boundary ceased to become a faultline, starting the process of mountain formation in the area.

Both the Rietic and the Akulanen Plate would continue to move northwards and fold towards each other. This made the Rietic Plate's slightly mountainous landscape. Ultimately the plate would merge with the Soltennan Plate.

Approximately 65 million years ago the Akulanen Plate started to subduct under the Rietic Plate. During this time volcanic and tectonic activity on the area increased. Volcanism would form most of the southern Rietic Mountains including Mount Lenthir and the Xynden Islands. Much of tectonic activity along both boundaries have subsided, however the southern parts remain to be active and in recent times have caused a number of major earthquakes, such as in 872 and in 1730 off the coast of Kenasha and Raushire respectively.
