Rhaegar was born during the Tragedy of Summerhall, a horrible event at the Targaryen pleasure palace that claimed many lives, including those of King Aegon V and his Lord Commander of the Kingsguard, famed knight Ser Duncan the Tall.
And make no mistake, this was no small sacrifice: to protect Lyanna with such an impressive trio it meant taking away sworn, loyal, and skilled guards from beside him in the war, away from his father, and away from his actual wife and two children.
It’s believed Rhaegar sent those three Kingsguard members to protect the woman he loved and their unborn child, who really would fulfill the prophecy of the prince that was promised, because he would be born of ice (Stark) and fire (Targaryen).
Rhaegar’s life, full of so much promise and hope, was short, and his love for Lyanna Stark resulted in his death and the deaths of thousands of others, but the child he left behind might not just extend his bloodline, his son might just save everyone.
