The Plains of Dayreht
The Plains of Dayreht cover most of the World Above Mehnihs. There are three major zones within the Plains: the Plains of Dayreht themselves, the Forests of Shehlahd in the center of the Plains, and the Rahkah Foothills to the east. While the foothills are often folded into the Plains of Dayreht when others speak of the region, the Forests of Shehlahd are considered a completely separate beast. The Vanai Family-Clan of Wood Elves inhabits the Forests of Shehlahd while the Queendom of Schatzenburg parcels out the Plains of Dayreht to individual Duchesses.
The Kahzay Rahkah Mountains
The Kahzay Rahkah Mountains are the southernmost part of the World Above Mehnihs. As you can see, this is not a single mountain range, but multiple ranges split up with rampant biodiversity. Even within the mountains themselves, however, people consider the entire region the Kahzay Rahkah Mountains. The Minami No Okina Ie, the Great Houses of the South, of the Stone Elves, occupy these Mountains.
