The Great War
The Demigor Mountains are the Southern Mountains of the Long Cross. While the mountains themselves are cold and harsh, under the mountains are expansive roads and mines where the Dwarves of Demigor thrive.
The treasures of the mountains flow within the Dwarves walls and cities and mining it has become a way of life. Of course with mining, the dangers of creatures from below is a constant threat. While the Dwarves hold the Elves on one front, they fight monsters and beasts from the other.
