This song is about a man who travels through time and sees the end of the world. On his way back to Earth to warn the human race, he goes through a magnetic storm and is turned to iron. Nobody believes him about the end of the world and he gets mad, taking his rage out on the human race, thus bringing about the end of the world that he saw. Sabbath bassist and lyricist Geezer Butler explained in NME that after Ozzy Osbourne put the idea in his head: "I was walking down the street one day and thought... 'what if there were a bloody great bloke made out of metal walking about?"' (thanks, James - Nottingham, England)
