Abridged History of the 10th Age
The Gnaefborg range is flung out from the Estbjar Mountains and protectively encircles the Feindal. Unlike the main mountains however, the Gnaefborgs have no mines throughout. Instead, there are several large fortresses that serve as lookouts and keep the mountain peaks clear of orcs and trolls. There are a few settlements that supply the Gnaefborg Fortresses in the mountains, but the region is otherwise uninhabited. The branch of the Deep Road that runs through the Gnaefborgs is called the Road of the Knife and is one of the only stretches of Deep Road that is still in perfect repair.
