Nephew of King Theoden of Rohan, Eomer is a captain in the King's cavalry. A skilled horseman and warrior, he led the forces of his people in battle against the Uruk's of Isengard in the Battle of Helm's Deep, routing the Uruk-hai, who had surrounded his Lord, and driving them into the forest and their doom. When Theoden chooses to rally to the defense of Gondor and ride to Minas Tirith, Eomer accompanies him, hurling his spear and swinging his sword against the forces of Mordor in the battle to protect the White City and the hope of all Middle-earth.
