King of the Men of the White Mountains
The King of the Dead
Dead Men of Dunharrow
The King of the Dead was the ruler of the Men of the White Mountains who swore allegiance to Isildur on the Stone of Erech and then refused his call to war against Sauron. Cursed to find no rest until the oath was kept, he and his people haunted the Paths of the Dead for three thousand years, until Aragorn summoned them to Pelargir and released them.
