Aelora Targaryen

In 215 AC Prince Rhaegel Targaryen choked to death on a lamprey pie during a feast, leaving the succession open under his uncle, King Aerys I. Aerys, who had no children of his own, had spent his reign naming and discarding nephews as possible successors.

Rhaegel's son Aelor then became Prince of Dragonstone and heir to the throne, with his twin sister and wife Aelora at his side. Two years later, though, Aelor died in a strange accident that was never explained: the one who caused it was Aelora herself.

After Aelor's death, Aelora was proclaimed Princess of Dragonstone and Princess of the Seven Kingdoms, heir to the Iron Throne, though the loss of her brother and husband left her in a madness she never recovered from.

At a masked ball she was attacked by three men nicknamed the Rat, the Hawk, and the Pig. Soon after, Aelora took her own life.
