Aelora Targaryen

Daughter of the feeble-minded Prince Rhaegel Targaryen and Lady Alys Arryn, twin to her brother Prince Aelor, to whom she was wed in the Targaryen fashion, with a younger sister Daenora. When Rhaegel died in 215 AC her uncle King Aerys I named Aelor Prince of Dragonstone, though there were those at court who, mindful of Lord Brynden Rivers and the line of succession, whispered that Rhaegel's twins would not be long for the world. In 217 AC she caused Aelor's death by some grotesque mishap and was left mad with grief, after which Aerys recognized her as heir to the Iron Throne in her brother's stead. Some time later three men remembered only as the Rat, the Hawk, and the Pig set upon her at a masked ball, and Aelora took her own life soon after.
