 In "The Hobbit", Thorin, a Dwarf-King in exile and twelve other Dwarves visited Bilbo Baggins in his home in the Shire.This was on the wizard Gandalf's advice to hire Bilbo as a burglar, to help them steal their treasure back from the dragon Smaug.Smaug had attacked the Dwarves's mountain, Erebor (the Lonely Mountain) about 150 years before, and had taken both the Dwarves' mountain and their treasure.
