Dragon (A Song of Ice And Fire)
From Concordances and Characters
The dragon is the symbol of the Targaryens, but the creatures themselves are generally considered to be extinct. Their bones are highly prized. Full-grown dragons were large enough to eat a horse in one gulp. Like most dragons, they have fiery breath and can fly.
They were first brought to the Seven Kingdoms by the Targaryens, three thousand years ago; a century and a half ago, the last misshappen hatchlings on Dragonstone died after living only a short time.
Dragon's eggs are still sometimes found, hard as rock, patterned in rich colours, with scaly surfaces.
