Mightiest of the dragons of Morgoth
Ancalagon the Black
Winged Dragons
The greatest dragon that ever lived, black and winged, whom Morgoth loosed from Angband as his last weapon in the War of Wrath. Eärendil slew him from the deck of Vingilot after a day and a night of battle in the air, and his fall broke the towers of Thangorodrim.
