The Lord of the Rings is the epic story of a fellowship of heroes questing to destroy the Dark Lord Sauron, a vengeful spirit intent on conquering the land of Middle Earth. Burdened with the titular Ring, an artifact of great power tied to the fate of Sauron's soul, the party journeys across Middle Earth on a harrowing path. The story deals with filial love, pastoralism versus industrialism, and the nature of bravery and justice.
