The nation of Almoren lay in the area that is now known as Cairhien, and bordered on what is now known as the Spine of the World. Almoren also bordered on the lands that were held by Tar Valon and the Aes Sedai of the White Tower.
Cities, Towns and Villages
The capital city of Almoren was Al'cair'rahienallen, which bears some resemblance to the name of the modern-day capital of Cairhien. During the construction of this city, the Ogier built a Waygate here. The only other city that we know of from Almoren is Jennshain.
Formation, Government, and Nobility
The nation of Almoren was formed sometime after Breaking of the World. The ruler who signed the Compact on behalf of Almoren was King Coerid Nosar. Other than this, of the government we know only sometime before the Trolloc Wars, Almoren was ruled by a Queen whose name we do not know.
Before the Trolloc Wars
The Trolloc Wars
Nothing is known of Almoren's participation in the Trolloc Wars, except for the fact that, of course, the nation stood against the Shadow.
After the Trolloc Wars
The nation of Almoren fell to the Shadow sometime during the Wars. We don't know the date, only the fact that Almoren did not survive.
