When she was heir to the Alderaanian throne, Breha Organa was severely injured in a fall while completing her Challenge of the Body. She would have died if not for the royal guards supervising from a distance. This led to the replacement of her heart and lungs with cybernetic pulmonodes. Breha's daughter Leia Organa, for her Challenge of the Body, asked her mother to accompany her on her climb.
Years later while on the planet Madurs during her honeymoon, Leia remembered her mother's fall as Leia recognised that the more she was celebrated the more people would seek her flaws, exploit them and use them to topple her image.
