Belfalas (S."Coast of Bel") was the mountainous peninsula that gave the Bay of Belfalas its name. It was also the domain of the princely line of Edhelion of Dor-en-Ernil. Although Pelargir and Lebennin had always been the heart of southern Gondor, the neighboring lands of Belfalas and Dor-en-Ernil proved to be the only dwelling of the Dúnedain-in-Exile where the legacy of the Faithful never grew dim throughout all the long tribulations of the Third Age. The line of the prince outlived even the royal house, favored as it was by Uinen the Maia, and could even boast of a union between Elf and Mortal—the equal of that achieved by Aragorn Elessar and Arwen Undómiel.
