You had not led a good life. When your eyes finally closed on that sick bed in King's Landing, you almost welcomed the Seven Hells as a change from the monotony of your life after the Greyjoy Rebellion. When your eyes opened again and you were staring at the room you lived in while you fostered with Jon Arryn, you were stunned. It appears as though the gods have seen fit to give you another life. Which gods, you know not, but you know you cannot fail. You have seen what the price of losing Lyanna was once already.
