Jorah is the son of Lord Commander Jeor Mormont of the Night Watch. He was exiled to Essos for smuggling slaves in the Seven Kingdoms. He originally worked as a spy to inform Robert Baratheon on the whereabouts of the Targeryans. However, Jorah developed an admiration for Daenerys and has supported her cause since.
