Who is Thorin?

Thorin Oakenshield

is the leader of the dwarves that accompany Bilbo to the cave of Smaug. Like most dwarves, he is focused on wealth, political ascendancy and historical lineage. He carries an old sword and he is heir to the throne established in Smaug's mountain. Unfortunately, Thorin's negative tendencies reveal themselves in his power-hungry maneuvers at the novel's end.
