Black Grass Valley Is a meeting grounds for the demons. It's an open valley with three rocks placed in the middle, One large and two small. The stones were placed their by the demons and they act as chairs for the leaders. Demons dont come here often and humans dont dare tread on these territories.
The valley itself is green, not black and its defined by its grassy stretch and how it is completly surrounded by dense forestry. It lies somewhere in the middle of all the territories.
