The Orocarni was a mountain range in the far east made by the Valar before Arda was marred and the symmetry was lost in the wars against Melkor.
On the western slopes of the Orocarni grew the Wild Wood, and near a great waterfall of a river that flowed into the Inland Sea of Helcar the bay of Cuiviénen lay, where the Elves woke.
At their northern edge the Orocarni connected with the Ered Engrin, forming a situation much as the Ered Luin in the far west.
Four of the seven Fathers of the Dwarves awoke in the range. The northern end of the Orocarni was home to the Ironfists and Stiffbeards, and in the southern end of the range awoke the Blacklocks and the Stonefoots.
