Ring, Isildur, already beginning to succumb to its corruption, chose not to do so. As such, although Sauron's physical form was vanquished, his spirit, bound to the Ring, survived. Some time later, Isildur was attacked and killed by a band of orcs, and the Ring was lost in the river Anduin for over two thousand years. Meanwhile, during the Third Age, a still weakened Sauron covertly established a stronghold at Dol Guldur. In response to this undetermined evil, the Valar sent five Maiar to Middle-earth. Taking the form of wizards, they were led by Saruman. Unsure of the origin of the evil power in Dol Guldur, the wizard Gandalf was sent to investigate. However, Sauron hid from Gandalf, waiting for four hundred years before returning. Around the same time, the One Ring was found by a Hobbit named Sméagol, who became utterly corrupted by it, living in the caves of the Misty Mountains, and physically transforming into a creature known as Gollum.

Sixty years later, Gollum was captured by uruk-hai, and taken to Mordor, where he was tortured into revealing the owner and location of the Ring; Bilbo Baggins of the Shire. In the meantime, Bilbo had left the Shire to live in Rivendell, and upon the advice of Gandalf had (very reluctantly) given the Ring to his nephew, Frodo Baggins. With the information given him by Gollum, Sauron, still unable to take physical form, thus sent the Nazgûl to the Shire to retrieve the One Ring. Frodo, and his friends, Samwise Gamgee, Peregrin "Pippin" Took and Meriadoc "Merry" Brandybuck managed to escape the Shire and make it to Bree, where they encountered the ranger Aragorn, the last surviving descendant of
