Niljaraen has written a description of the Gordawir Mountains, mainly inhabited by trolls.
The primary inhabitants of the area are the Gordawir trolls. They originally entered the area as one tribe – the Hollow Log tribe – but they have since expanded and separated, so there are now various distinct tribes throughout the mountains. Yet after all this time they are secretive and have very little contact with other races. Harried by dragons when they first entered the mountains, they took to the deep caves and secluded valleys, largely unexplored by anyone else, and that remains the case to this day. Whether or not dragons still remain too is a question probably known only to the local trolls themselves.
