Once the Anchient Kingdom of Arnor had fallen, it was divided into three states of the Dunedain of the North. Because of a disagreement of the three brothers of King Eärendur. Each brother recived one peice. These soon became independant states, which were Cardolan, Arthedain, and Rhudaur. The contention between the three kingdoms was largely over the line of Isildur which, in the kingdoms of Cardolan and Rhudaur, diminished quickly.
However the Line held in Arthedain, which held dominion over Weathertop (Amon Sul) and this area now known as the Lone Lands. About T.A. 1272 Orcs began to trouble the region and The Which King had established a new kingdom to the North, Angmar. During this time Argeleb I, king of Arthedain, claimed lordship over the three kingdoms as he was the remaining of the bloodline of Isildur. Rhudaur resisted this new reign and allied with Angmar. They fought for control of Weathertop and the Weather Hills became the site of many battles and warfare between the three kingdoms. After the death of Argeleb I, Cardolan was ravaged and Rhudaur was occupied by Angmar.
As the war raged on the Kingdom of Arthedain was pushed back until the battle of Fornhost in TA 1975. These lands had been barren ever since. But remnants of castles and defenses remain ruined here. They are often found to be home to new masters now. Though much less organized the ruins and fortresses house wild animals as well as brigands and outcasts.
The traveler would be wise to stay to the side of the road yet not stray so far. There is danger in both. The ruins are rarely unoccupied so camping in a group of rocks is more safe than gathering by the old stones. Fires should be kept low and out of sight. The wild animals range from cats and wolves to much worse.
A well prepared traveller would have brought provisions with them as there is little to pind in the way of food here, save for the local bobcats. Berries and nuts are scarce in the dry land so make sure to packwellandplan ahead.
Furthermore, plan the trail through these lands, make for the fastest trip. Travel by day as the road grows even darker at night. A safe stop lies at the beginning of the road at The Forsaken Inn and the last safe house remains Ost Guruth. After this make no hesitation until you reach the Trollshaws.
