Dúnachar
The sword formerly wielded by Golodir was renamed Dúnachar, Avenger of the West by Elrond after it was reforged from the remains of Golodir's old sword. The old sword was forged long ago by the Elves of Rivendell and was an heirloom of Golodir's family.
The sword first appears in the Vol. 1, Book 8 quest [49] Chapter 3: Forging the Sword.
