Khathog, the Priest of Darkness, was thoroughly evil. A cruel and implacable enemy, he was trained under the Witch-king and had returned to the Ered Tarthonion in order to revive the Dark Worship among his kinfolk. He travelled in isolated areas with his lesser priests and guards, sometimes leading rituals at the old sites of Sauronic worship. Of course, he never referred to his master by his true name, instead calling him the "Dark Prophet" or the "King of the World."
