Queen Rhaenys Targaryen is an unseen character mentioned in the second season. She lived and died centuries before the events of the series, and is not expected to appear. She was the sister and wife of Aegon the Conqueror and helped him in his invasion and conquest of Westeros three centuries before the events of the series. Rhaenys and her sister Visenya were (simultaneously) the first Queens of the Andals and the First Men. Since her nephew Maegor Targaryen died without issue, all subsequent Targaryens were descended from Rhaenys, not Visenya. Rhaenys is pronounced "Ray-niece".
