"There is a certain kind of pain that can change you. Even the strongest sword, when placed in a raging fire, will soften and bend and change its form... Trust me on this one. I know this from personal experience. I hope that you never will, but, since you're a person, and therefore prone to making horrible, soul-splitting mistakes, you probably will one day know what this kind of guilt and shame feels like. And when that time comes, I hope you have the strength...to take advantage of the fire and reshape your own sword."
