We are introduced to the Powers and their leader Verchiel, a cruel, relentless angel who feels it is his sacred mission in the name of the most Holy to eradicate the Fallen and their offspring from the face of the Earth. He especially wants to eliminate the Nephilim spoken of in the Prophecy who is supposed to redeem the Fallen, forgive them of their sins against the Creator and send them back home to Heaven. Eventually, Aaron meets Verchiel for the first time. Zeke and Camael come to the rescue, but not before Verchiel kills Aaron's adoptive parents and takes his brother Stevie captive. Enraged, Aaron's angelic nature takes over and he battles with Verchiel.
