Thornscrapes
A line of high, rugged hills east of Farnfoss in the Confederation of Uth. The area around them is wilderness, and they themselves are covered in thick briars and brambles.
Local legends hold that a citadel once stood at the Thornscrapes' center, but fell into the earth centuries ago in some sort of magical cataclysm, and it is now called The Sunless Citadel. Monsters are said to infest these hills as well, and most people stay far away.
