The nation of Aridhol was located in what is now largely unclaimed territory, near the northern half of the Mountains of Mist. To the north was Jaramide, with Aramaelle to the northeast, Coremanda to the southeast, Manetheren to the south, and Safer to the west.
Cities, Towns, and Villages
Other cities in Aridhol included Abor'maseleine and Cyrendemar'naille.
Formation, Government, and Nobility
Like the other nations in its time, Aridhol was formed sometime after the Breaking of the World.
Before the Trolloc Wars
Nothing is known of Aridhol before the Trolloc Wars.
The Trolloc Wars
Like the other nations of the Compact, Aridhol stood against the Shadow.
During the Trolloc Wars, Aridhol fell from within. It was a shadow that consumed it, but a shadow that was not of the Dark One. A man called Mordeth arrived at Aridhol and became an advisor to king Balwen, feeding him and his people the illusions that to win, they must be more cruel than the Shadow and less trusting (LoC, Ch. 21). In the end, the people of Aridhol became so suspicious and hateful that they turned on each other, breeding an evil that later became a mist roaming around the abandoned city. When soldiers from Manetheren came to the walls of Aridhol, they found no living thing in the city, only the deadly Mashadar (TEotW, Ch. 19).
After the Trolloc Wars
By the end of the Trolloc Wars, the nation of Aridhol had been destroyed.
