...and as Tuor went he saw that the sun was sinking low into a great black cloud that came up over the rim of the darkening sea; and it grew cold and there was a stirring and murmur as of a storm to come. And Tuor stood upon the shore, and the sun was like a smoky fire behind the menace of the sky; and it seemed to him that a great wave rose far off and rolled towards the land... And the wave came towards him, and upon it lay a mist of shadow. Then suddenly as it drew near it curled, and broke, and rushed forward in long arms of foam; but where it had broken there stood dark against the rising storm a living shape of great height and majesty. A tall crown he wore like silver, from which his long hair fell down as foam glimmering.
