Eaerlann

Eaerlann was a powerful elven kingdom of wood and moon elves in the valley of the Delimbiyr River and the eastern High Forest that lasted for around six thousand years. Together with Sharrven it supressed the spread of evil in Silvanuede and maintained the peace.

In 882 DR the combination of the demonic invasion of Ascalhorn, the contined assult of the Orc hordes and the weaking of the kingdom by the elves leaving for Evermeet resulted in the kingdom's collapse.

Ecology
The Eaerlann made their homes by hollowing out the trees and connecting them with rope bridges. Because of this, many of their settlements have not withstood the effects of time and are no longer present.
