The Hammer of Sauron
The Hammer of Sauron is the tertiary antagonist in Middle-earth: Shadow of Mordor. He was one of Sauron's Black Captains and was responsible, partly, for the murder of Talion and his family during the retaking of Mordor by the Dark Forces.
The Hammer of Sauron was once a man, a stretcher bearer for Gondor dedicated to retrieving the wounded. His life changed on the slopes of Mount Doom when he retrieved Sauron's mace after the Dark Lord fell.
