Bail Organa, the Viceroy of Alderaan, penned a letter to Breha, his wife and Queen, soon after being given the baby daughter of the late Padmé Amidala. He explained that, despite the tragic passing of Amidala, an extraordinary event had transpired that would forever alter their destiny—alluding to Leia, the infant they were going to adopt. A duplicate of this correspondence endured the destruction of Alderaan at the hands of the Galactic Empire. It was subsequently archived within the Breha Organa Collection at the Alderaan Memorial situated on Coruscant. This very copy was later incorporated into Leia Organa's life story, composed by an archive droid amidst the conflict involving the Resistance and the First Order.
The canon reference work, Princess Leia: Royal Rebel by Calliope Glass, initially presented the letter in 2016.
