Low grey skies, swirling clouds, rough, huge boulders, and lush sea buckthorns.
Those were the unique features of the Dwarven outpost.
The Gray Dwarves may be called Dwarves, but they were very different from actual Dwarves. The Dwarves, Gray Dwarves and Hobbits in the Lord of the Rings world were all shorter than a meter, but their differences were very distinct. They were a bit similar to the Dwarves, Goblins and Gnomes in WoW.
The most distinct feature of the Gray Dwarves were their large ears, their messy hair, and their evil smile. Because they lived in such a desolate land, even the faces of younger Gray Dwarves were full of wrinkles. Their flesh and blood contained a terrible stench, while their souls were distorted and in tatters. They had no use to creatures of darkness. That was also the reason why they could survive here and do business with the creatures of darkness.
