The Mountain-Elves (Av."Iridlai") or Oroneldi were an Avar tribe originally native to the Mountains of Mirkwood. They were remnants of the Windan. They tended to stay away from their telerin brethren and only grudgingly accepted the rule of the Sindarin exiles in Mirkwood, though they later largely intermingled with the other , nandorin Mirkwood-Elves as their mountain homes became more and more unsafe and Orcs and Trolls subject to Dol Guldur started to occupy their former homes.
Notes[]
J. R. R. Tolkien never explicitly mentions the Mountain-elves but relatives of the Wood-elves living somewhere in the hills or mountains are refered to briefly in The Hobbit.
