Erebor
Thorin Oakenshield is a fictional character in J. R. R. Tolkien's 1937 novel "The Hobbit". Thorin is the leader of the Company of Dwarves who aim to reclaim the Lonely Mountain from Smaug the dragon. He is the son of Thráin II, grandson of Thrór, and becomes King of Durin's Folk during their exile from Erebor. Thorin's background is further elaborated in Appendix A of Tolkien's 1955 novel "The Return of the King", and in "Unfinished Tales".
