How can you not remember the Dwarves? They're the whole reason for the adventure XD

The Lord of the Rings Trilogy is Three books, all fatter than the Hobbit! I guess the thing was, they wanted to take information from the various LotR appendices and incorporate it into the Hobbit to make it more cohesive with the universe. Because The Hobbit was written before the rest of it was conceived and a lot of background info pops up in the appendices.

Indeed.
