Halruaa

Surrounded by mountain ranges on three sides and the Great Sea along the south, the great delta-plain of Halruaa was almost totally insulated from its neighbours.
The great delta of Halruaa stretches approximately 500 miles (804 km) from east to west, and more than 350 miles (560 km) from its southern border of the Great Sea to its northern foothills. It is divided into sections by three rivers that meet at Lake Halruaa. The vast majority of the land consists of flat, windswept plains, broken only by broad rivers or other notable landmarks. Common fauna in the region include rothé and aurochs.
The plain is bordered by mountain ranges on its north, east, and west sides, known as the Walls of Halruaa, that act as natural barriers to the plain. The range to the north is known as the Nathaghals (the North Wall), the range to the east as the Muaraghals (the East Wall), and to the west, the Lhairghals (West Wall). There is a narrow land of hill grasslands in the Nathaghals called the High Aluar, and this is the only non-mountainous land entrance to Halruaa. It can be accessed through the mountains at Talath Pass in the west, or Azhal Pass in the east.
All the major rivers in the region start from the Walls of Halruaa, and drain into Lake Halruaa.

Climate for Halruaa

Halruaa is a warm and humid land, with daytime temperatures of up to 37°C in the summer, to between 20°-26° in winter. The climate is cooler and more comfortable in the highlands than in the lowlands. Some mountains even have snowcaps. Because of its mountain ranges, moisture rolling in off the sea can produce sudden and frequent thunderstorms.
