In the palace, during my imprisonment, I learned that Maven had been made by his mother, formed into the monster he became. There is nothing on earth that can change him or what she did. But Cal was made too. All of us were made by someone else, and all of us have some thread of steel that nothing and no one can cut. I thought Cal was immune to the corruptive temptation of power. How wrong I was. He was born to be a king. It's what he was made for. It's what he was made to want.
