An enemy, Ender Wiggin," whispered the old man. "I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher.

Even though some of the oldest trees here came from warriors of two different tribes, fallen in battle. We become one tribe because we say we're one tribe." Ender marveled at his mind, this small raman [member of another sentient species]. How few humans were able to grasp this idea, or let it extend beyond the narrow confines of their tribe, their family, their nation.
