- "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.
 Portrayal in adaptations
- Speaking about dragons, Thranduil tells to Thorin that he knows dragonfire, as in the past he has fought "the serpents of the North". Saying this, his cheek decomposes, as if some old wound is returning. This is erroneous, as Cold-drakes do not breathe fire.
2018: The Lord of the Rings Online:
- Cold-drakes appear throughout the northern lands of Middle-earth, particularly in the Ered Mithrin where they serve "Hrímil Frost-Heart", a dragon who consumed one of the dwarven Rings of Power. Hrímil's mightiest spawn, the Cold-drake "Vethúg Wintermind", was the one to slay King Dáin I and his son Frór in Thikil-gundu, "The Steel Keep" (otherwise known as Dáin's Halls).
