Grashakh is roughly at he heart of the Brucrumus continent. The region's terrain is on the average, higher than all neighboring regions. Many waterways begin here and end in another region. The region's west is a wall of mountains called the Giant Steps. In the Titan Era, these peaks were home to a frost giant empire of such might that only other Titan Empires could contest it.
Between the area's ten mountainous parts are vast grasslands, one pitted with cavities plunging into the Underdark, dreary cold swamps, great lakes, fast rivers, and deep forests. Except for the Vigath-Mazgob Canal, all the region's great waterways flow south.
In the Second Epoch, orcs under an ageless leader marched north into this region. In what became known as the Arduous March, they carved out a new living space. These orcs, so different than your normal orcs, are the Githirmil. Most of them are citizen-soldiers of the Orchish Empire.
Beneath Grashakh is the Underdark region Imgangreth.
