Iron Hills

The Iron Hills are a range of mountains in the north of J. R. R. Tolkien's fictional world of Middle-earth, east of the Lonely Mountain, that are home to a Dwarf mining community. In The Hobbit, the Dwarf warrior Dáin II Ironfoot of the Iron Hills led an army to the defence of Thorin Oakenshield which then joined in the Battle of Five Armies. The Iron Hills are remnants of the Iron Mountains (Middle-earth) where Morgoth dwelt.
