"The three of us." I tapped my chest, pointed to Omega, and continued, "Myself, my broher, and Chaos are from a seperate dimension, parallel to yours but... different. There, the reigning power is a being, immensely powerful, known as The Author. He... created us, dreamt us into being." I smiled somewhat apologetically, saying, "It is rather hard to explain to one who is not familiar with the laws of my home." Omega glowered at me for revealing such secrets, though he said, "If you're going to say it, tell the whole story."
I sighed and said, "I was getting to that, Omega. That is how Chaos is different from us, The Author did not willingly, or even knowingly, create him. You see, our lord and mast is everything Chaos is not. Kind, compassionate, loving and friendly. Evil and sadism do not exist in him. They were forced into his shadow self, a twisted duplicate of who he is. Chaos. That is why they cannot be killed, they depend on each other to be truly whole. No being is pure good or pure evil, they must have a spark of the other. They created each other."
