" What you will learn is knowledge that you cannot share within the mortal world. Possessing it will make you different from others. It will give you great wisdom, Phae. However, in much wisdom is much grief. And they that increase knowledge also increase sorrow. As you learn the truth, you will grieve. But I promise you that the fruit of that knowledge, while bitter to the taste, is also most sweet too. "
