Did you ever notice how in the Bible, when ever God needed to punish someone, or make an example, or whenever God needed a killing, he sent an angel? Did you ever wonder what a creature like that must be like? A whole existence spent praising your God, but always with one wing dipped in blood. Would you ever really want to see an angel?
I remember the First War. The way the sky burned, the faces of the angles destroyed. I saw a third of Heaven's legion banished and the creation of Hell. I stood with my brothers and watched Lucifer's Fall, but now my brothers are not brothers, and we have come here where we are mortal to steal the Dark Soul, not yet Lucifer's, to serve our Cause. I have always obeyed, but I never thought that War would happen again.
