A chance encounter with what Aaron thinks is a homeless bum turns out to be a Fallen Angel by the name of Ezekiel ("Zeke"). It was Zeke who sensed Aaron's true nature and told him what he really was: a Nephilim, the offspring of an angel and a mortal woman. Zeke warns Aaron that the Powers will hunt him down and kill him, that he must learn how to use his divine gifts and flee immediately. Aaron, of course, thinks the man is insane. Nevertheless, Aaron goes to his local library and looks up information on Nephilim. He begins to wonder if it could be true. Another angel, Camael, appears at his high school and tells him that he is the chosen one that the angels have been waiting for: the one spoken of in the Prophecy. Camael tells Aaron that he has come to protect him from the Powers and help him fulfill his destiny.
