Dragons were the heaviest of all the servants of Morgoth; they were also his last servants. There were two kind of Dragons: the Fire-Dragons and the Cold-Dragons. Fire-Dragons breathed fire and were initially wingless. Cold-Dragons had wings and were able to fly; they had less power of fire than Fire-Dragons.

Dragons are cunning and clever creatures with razor sharp minds. How precisely they were bred, and of what, is nowhere told; we suspect they were made by sorcery and fire. In the early tales, it is said that the serpents had hearts of fire and bodies of steel.

Dragons had sharp and keen eyes, an exceptional sense of smell, and a suberb memory. If they once sensed a smell, it was never forgotten. And, no matter how great a treasure they had stolen and were guarding they knew the exact amount to the penny. They would furthermore know if just the tiniest jewel were missing from the treasure.
