Description

The last dragon belonging to House Targaryen died young in 153 AC, during the later part of the reign of King Aegon III, who was called the Dragonbane. Her death marked the extinction of dragons in Westeros and beyond, until Daenerys Targaryen managed to hatch three dragons around a century and a half later

The last dragon had been a green female, who lived in King's Landing. She was sickly, small, misshapen, and stunted, with withered wings. Her name is not known.

The last dragon was born to House Targaryen during the reign of King Aegon III Targaryen. Although she was sickly, she laid a clutch of five eggs, which never hatched. The last dragon died in 153 AC in King's Landing. Ser Arlan of Pennytree had seen the last dragon, the previous year, as well as her dragon eggs, which he described as 'hard as stone, but beautiful'. Some rumors claimed that Aegon III poisoned her, as he had been afraid of dragons since the day he had seen his uncle's dragon devour his mother.

In the final years of the Targaryen dynasty, nineteen dragon skulls hung the walls of the throne room. Two of these were no bigger than a mastiff's skull, and oddly misshapen, and both had been born on Dragonstone. Due to the description of the skulls, one of them might have been the skull of the last Targaryen dragon. It is thought by some that magic had begun to leave the world the day the last dragon died.
