Description
The Lonely Mountain of Erebor was once the home of the Dwarves of Durin until the dragon Smaug sacked the city.
In "The Hobbit", Bilbo Baggins joined Gandalf and Thorin along with his dwarf kinfolk to reclaim their home and the riches that lay beneath the mountain.
The mountain is the location of The Battle of the Five Armies where the dwarves, lake-men, elves, goblins, and wargs battle for the endless supply of riches that are locked away beneath the mountain.
