"Upon it sat a shape, black-mantled, huge and threatening. A crown of steel he bore, but between rim and robe naught was there to see, save only a deadly gleam of eyes: the Lord of the Nazgûl... now he was come again, bringing ruin, turning hope to despair, and victory to death. A great black mace he wielded. "
