There was a roar and a great confusion of noise. Fires lept up and licked the roof. The throbbing grew to a great tumult, and the Mountain shook. Sam ran to Frodo and picked him up and carried him out to the door. And there upon the dark threshold of the Sammath Naur, high above the plains of Mordor, such wonder and terror came on him that he stood still forgetting all else, and gazed as one turned to stone. Fire belched from its riven summit. The skies burst into thunder seared with lightning. Down like lashing whips fell a torrent of black rain. And into the heart of the storm, with a cry that pierced all other sounds, tearing the clouds asunder, the Nazgûl came, shooting like flaming bolts, as caught in the fiery ruin of hill and sky they crackled, withered, and went out.
