In the Second Age, the Dark Lord Sauron attempts to conquer Middle-earth using his One Ring. In battle against Sauron, Prince Isildur cuts the Ring from Sauron's hand, destroying his physical form. However, Sauron's life force is bound to the Ring, allowing him to survive while the Ring also survives. Isildur, corrupted by the Ring's power, refuses to destroy it. When Isildur is killed by Orcs, the Ring is lost in a river for 2,500 years. The Ring is found by Gollum, who possesses it for five hundred years until it is found by the Hobbit Bilbo Baggins. Sixty years later, Bilbo leaves the Ring to his nephew, Frodo Baggins. Upon learning the Ring belonged to Sauron, the Wizard Gandalf the Grey warns Frodo that Sauron's forces will come for him, and has Frodo leave the shire accompanied by his friend Samwise Gamgee. Gandalf rides to Isengard to meet with the head of his order, Saruman the White, who reveals that Sauron's servants, the Nazgûl, have been sent to capture the Ring. Saruman reveals himself to be in service to Sauron and imprisons Gandalf atop his tower. Saruman commands Sauron's Orcs to construct weapons of war and produce a new breed of Orc fighters: the Uruk-hai
