One of the interesting things about The Lord of the Rings is how the story spans across Middle-earth, which gives an opportunity to explore so many areas of this world that Tolkien has created. Different races with different customs and histories are introduced, and each becomes important in the story in a different way. The Elves, for example, are one of the oldest peoples of Middle-earth, and they have established multiple kingdoms throughout the land. There are different kinds of Elves as well, including some that are incredibly powerful and can wield magic.
