Ephraim was an angel hailing from a special class. He fell to the earth from heaven due to a spell cast by Metatron. While on earth, he continued his work as a medical angel--healing the sick and, more importantly, bringing swift and virtually painless death to the gravely injured or emotionally despondent by smiting them. He came across Castiel, who Ephraim wanted to help by ending his pain once and for all.
