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. Thier land was bound by the eastern part of the High Forest, from Turnstone Pass, in the north to the Shining Falls in the south.

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. After the collapse some of the Elves of Eaerlann joined with Dwarves and Humans to form the Fallen Kingdom.

All that remians of the kingdom of Eaerlann is a crumbling old road and a ruined port

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.
