The ancient kings who became spectres
The Nazgul are creatures that we find in a recurring way in the Lord of the Rings, the famous cinematographic and literary work of heroic fantasy. The story tells of the struggle between Sauron, the terrible lord of Mordor, and the alliance of free peoples to prevent him from taking over Middle Earth. Thousands of years ago, Sauron created rings of power and gave them to the greatest kings of the major races: nine for men, seven for dwarves and three for elves. But he also created a ring that would control them all. While the elves resisted, the men were corrupted by its power and the nine kings became Nazgul, creatures not truly alive but not dead either, and responsive only to the power of the ring. When, thousands of years later, Sauron regains his strength, he sends them in search of the ring.
