“ My Son,” Aegis stopped him in one of his tantrums. “Anger and rage are powerful. For you they are strength. They will make you stronger than many men, faster than your own horse, and they will show you things beyond your world. But you must control them. You must always be their leader. If ever, even for a moment, you let anger out of your control, it will rule you and betray you to those who would harm you. ”
