For latecomers to the world of Tolkien’s “The Hobbit” and “The Lord of the Rings” trilogy, here is a legend to the key players.
The Free Races
“Free” generally means not under the dominion of the dark lord Sauron. It also indicates a higher stature of morality.
Dwarves
Short, barrel-chested, scary-strong, and long of beard, dwarves love mountains and caves. Their kingdoms were the Lonely Mountain and the Mines of Moria (Khazad-dum). They build and create with precious metals and gemstones. They are aggressive, supremely stubborn, and fierce in battle.
