The Mighty Fall

I'm an angel...well I was, before the angels fell. But what's an angel without it's wings? I never really knew how good I had it, having no emotions, that is, before the fall, and now the flow of human emotion is very hard to bear. My name is Selaphiel, and my best friend was Ezekiel. He died in the fall, and I heard rumors about who had caused the angels to plummet to the Earth, who caused my beautiful wings to burn off of my back. His name was Castiel. He was a rebel angel, I'd heard of him before. I seek revenge against the angel that damned the rest of us. I will defeat Castiel and try my hardest to get the angels back to Heaven.
