Arvernien

The northern coastlands of the Bay of Balar, lying between Cape Balar to the west and the Mouths of Sirion to the east. The inland part of this region was famed for the white birchwoods of Nimbrethil.

Arvernien was the most southerly habitable part of the mainland of Beleriand, and thus the furthest from Morgoth's influence. This became important late in the First Age, when refugees from Doriath and Gondolin gathered there, especially in the east at the Mouths of Sirion. Eärendil became the lord of these people, and it was from the birchwoods of Arvernien that he gathered the timbers to make his ship Vingilot.
