- "Now the least mighty - yet they were very great beside the Men of those days - are cold as in the nature of snakes and serpents, and of them a many having wings go with the uttermost noise and speed..."
- ― Turambar and the Foalókë
As the millennia passed, their numbers grew, until they became a serious threat in the later centuries of the Third Age to the Dwarves that mined the Grey Mountains. In T.A. 2589, Dáin I, King of Durin's Folk, and his second son Frór were slain at the gates of their halls by a Cold-drake. The attacks of these fearsome creatures persuaded the Dwarves to migrate eastwards from the Grey Mountains, and it was soon afterward that their realms in the Iron Hills and at Erebor were established.
