J.R.R. Tolkien, Adaptations 

adventure follows Bilbo Baggins, who is swept into an epic quest to reclaim Erebor with the help of Gandalf the Grey and 13 Dwarves led by the legendary warrior, Thorin Oakenshield. Their journey will take them through treacherous lands swarming with Goblins, Orcs and deadly Wargs, as well as a mysterious and sinister figure known only as the Necromancer. Although their goal lies to the East and the wastelands of the Lonely Mountain, first they must escape the Goblin tunnels, where Bilbo meets the creature that will change his life forever...Gollum. Here, alone with Gollum, on the shores of an underground lake, the unassuming Bilbo Baggins not only discovers depths of ingenuity and courage, he also gains possession of Gollum's "precious" ring that holds unexpected and useful qualities...A simple, gold ring that is tied to the fate of all Middle-earth in ways Bilbo cannot begin to know.
