The wide seaward land to the west of the Blue Mountains is the Elven realm of Lindon. The region is what remains of the great country of Beleriand, destroyed almost entirely in wars that only the long-lived Elves remember.
It was for a while the greatest nation of the Elves in Middle-earth. Gil-galad, the last king of the Noldor, dwelt there, as did Celeborn and Galadriel, before they went to Lórien.
In time, Celebrimbor led many of the High Elves away east, to found Eregion, after hearing of the discovery of mithril in the mines of Moria.
The land of Lindon comprises Forlindon and Harlindon, the coastlands to the north and south of the Gulf of Lhûn.
No Men cross into Lindon, but Dwarves still maintain some remote halls in the Blue Mountains, both north and south of the Gulf of Lhûn.
Those are the sea-side lands from which Aredhel hails.
