GALADRIEL: It began with the forging of the Great Rings. Three were given to the elves, immortal, wisest and fairest of all beings; seven to the dwarf lords, great miners and craftsmen of the mountain halls; and nine, nine rings were given to the race of men, who, above all else, desire power.
Galadriel's introduction lays it all out for us. Each race has its own distinct characteristics, both in terms of lifestyle and personality. (If you want to get down to the brass tacks, head over to our Type of Being section under Characterization, where we do a quick and dirty break down of each stereotype.)
