King Aegon the Conqueror had a younger sister, the one who was his ray of sunshine, whom he swore to protect on his mother's deathbed.

He named her princess when he conquered the Seven Kingdoms and gave her everything she wanted, even a palace she would come to call the Palace of the Sun. Aegon could spend the whole morning listening to her talk or simply standing there and watching her.

And then one fine day he kissed her, and to his surprise, she kissed him back. That family have aways been strange with their feelings.

Since then, she has more than just his younger sister, and it was getting out of hand. The entire kingdom knew it, but Aegon simply didn't care. They were those who were above any moral rule.
