Quenya word meaning 'fire-serpent', dragon. 137, 294-304, 308
Quenya word meaning 'fire-serpent', dragon.
The fire-drakes; dragons who breathed fire. Glaurung, Father of Dragons, was the first of these. He first appeared in the middle of the First Age, but the urulÃ³ki certainly survived the downfall of their master, Morgoth.
Ancalagon apparently belonged to this kind, and Smaug, the great fire-breathing dragon that sacked Erebor, seems to have been the last of the great urulÃ³ki. Other lesser types apparently survived to the end of the Third Age and beyond.
