|Description||Probable capital city of the Dwarves of the Grey Mountains|

The Halls of Dáin were probably originally founded by the first exiled dwarves from Khazad-dûm who had fled the city because of the Balrog. However because there is no information on the halls, it can only be assumed that it was the capital of Durin's folk at the time.
In T.A. 2589 Dáin was killed by a great Cold-Drake along with his son Frór at the entrance to the city. A year later, most of Durin's folk abandoned the mountains, and left for Erebor and the Iron Hills.
