Hobbits are a fictional race of people in the novels of J. R. R. Tolkien. About half average human height, Tolkien presented hobbits as a variety of humanity, or close relatives thereof. Occasionally known as halflings in Tolkien's writings, they live barefooted, and traditionally dwell in homely underground houses which have windows, built into the sides of hills, though others live in houses. Their feet have naturally tough leathery soles (so they do not need shoes) and are covered on top with curly hair.

Hobbits first appeared in the 1937 children's novel The Hobbit, whose titular Hobbit is the protagonist Bilbo Baggins, who is thrown into an unexpected adventure involving a dragon. In its sequel, The Lord of the Rings, the hobbits Frodo Baggins, Sam Gamgee, Pippin Took, and Merry Brandybuck are primary characters who all play key roles in fighting to save their world ("Middle-earth") from evil. In The Hobbit, hobbits live together in a small town called Hobbiton, which in The Lord of the Rings is identified as being part of a larger rural region called the Shire, the homeland of the hobbits in the northwest of Middle-earth. Some also live in a region east of the Shire, Bree-land, where they co-exist with Men.

Valinor (Quenya: Land of the Valar), the Blessed Realm, or the Undying Lands is a fictional location in J. R. R. Tolkien's legendarium, the home of the immortal Valar and Maiar on the continent of Aman, far to the west of Middle-earth; he used the name Aman mainly to mean Valinor. It includes Eldamar, the land of the Elves, who as immortals are permitted to live in Valinor.

The name "the Undying Lands" does not mean that the land itself causes mortals to live forever. Generally, only immortal beings are allowed to reside there. Exceptions are made for the surviving bearers of the One Ring: Bilbo and Frodo Baggins and Sam Gamgee, who dwell there for a time, and the dwarf Gimli.

In J. R. R. Tolkien's epic fantasy novel The Lord of the Rings, the Battle of the Morannon or the Battle of the Black Gate is the final confrontation in the War of the Ring. Gondor and its allies send a small army ostensibly to challenge Sauron at the entrance to his land of Mordor; he supposes that they have with them the One Ring and mean to use it to defeat him. In fact, the Ring is being carried by the hobbits Frodo Baggins and Sam Gamgee into Mordor to destroy it in Mount Doom, and the army is moving to distract Sauron from them. Before the battle, a nameless leader, the "Mouth of Sauron", taunts the leaders of the army with the personal effects of Frodo and Sam. Battle is joined, but just as it seems the army of Gondor will be overwhelmed, the Ring is destroyed, and the forces of Sauron lose heart. Mount Doom erupts, and Sauron's tower, Barad-dûr, collapses, along with the Black Gate. The army of Gondor returns home victorious, the War of the Ring won.
