Ringwraiths

The nine Ringwraiths, or Nazgul, were once great kings of men in Middle-earth during the Second Age. But during the latter half of the Second Age Sauron had seduced them with promises of glory and gave to them nine rings of power. Being blinded by their greed they took them without question.

Though their rings had given them much power over those they ruled, when Sauron forged the One Ring they became his slaves. They eventually became shadows of their former selves and became trapped between the worlds of the living and the dead, no man could kill them. The Ringwraiths were known as the Dark Lord's most loyal and deadly servants.

The leader of the nine was called the Witchking of Angmar, it was believed that when he was still human he was also a sorcerer. He became the captain of Sauron's armies in war. During the latter half of the Third Age he led the other Ringwraiths in the two year siege of Minas Ithil, one of Gondor's chief cities. After the city had been taken he made his lair and renamed it Minas Morgul.

He is also known as the orchestrator of the fall of Arnor.

During the War of the Ring it was the Witchking that commanded the assault on Minas Tirith. But when the Roherrim had interviened in the siege, Eowyen, the niece of King Theoden, had killed the Witcking in single combat. And with his death, Sauron's army had lost order and was defeated in the Battle of the Pelennor Fields.

The remainder of the Ringwraiths were destroyed when the One Ring was cast into Mount Doom.
