Daenerys was born on the Targaryen island refuge of Dragonstone eight months after her father's death. Her mother died giving birth to her, and a great storm raged at the moment of her birth, destroying what was left of the Targaryen fleet anchored at Dragonstone, giving rise to the nickname "Stormborn". The infant Daenerys and her brother Viserys were spirited into exile across the Narrow Sea by Ser Willem Darry, a loyal retainer of their family, before the castle garrison could hand them over to Robert Baratheon.
