Dwarves don’t play a huge role in Middle-Earth during the time of Frodo’s journey, but they do in the time of The Hobbit. Gimli is the only dwarf with a major role in Lord of the Rings. Dwarves were removed from their house in the Third Age. Their home was in the Misty Mountains. There, they were very prosperous due to the mountain’s gems and metals. They enjoy parties, and they aren’t very smart. They also enjoy fighting. Overall, dwarves can be fun, but serious when they need to.
