The Silmarillion

But the land of Aman and Eressëa of the Eldar were taken away and removed beyond the reach of Men for ever. And Andor, the Land of Gift, Númenor of the Kings, Elenna of the Star of Eärendil, was utterly destroyed. For it was nigh to the east of the great rift, and its foundations were overturned, and it fell and went down into darkness, and is no more. And there is not now upon Earth any place abiding where the memory of a time without evil is preserved. For Ilúvatar cast back the Great Seas west of Middle-earth, and the Empty Lands east of it, and new lands and new seas were made; and the world was diminished, for Valinor and Eressëa were taken from it into the realm of hidden things.

In an hour unlocked for by Men this doom befell, on the nine and thirtieth day since the passing of the fleets. Then suddenly fire burst from the Meneltarma, and there came a mighty wind and a tumult of the earth, and the sky reeled, and the hills slid, and Númenor went down into the sea, with all its children and its wives and its maidens and its ladies proud; and all its gardens and its halls and its towers, its tombs and its riches, and its jewels and its webs and its things painted and carven, and its lore: they vanished for ever. And last of all the mounting wave, green and cold and plumed with foam, climbing over the land, took to its bosom Tar-Míriel the Queen, fairer than silver or ivory or pearls. Too late she strove to ascend the steep ways of the Meneltarma to the holy place; for the waters overtook her, and her cry was lost in the roaring of the wind.

But whether or no it were that Amandil came indeed to Valinor and Manwë hearkened to his prayer, by grace of the Valar Elendil and his sons and their people were spared from the ruin of that day. For Elendil had remained in Romenna, refusing the summons of the King when he set forth to war; and avoiding the soldiers of Sauron that came to seize him and drag him to the fires of the Temple, he went aboard his ship and stood off from the shore, waiting on the time. There he was protected by the land from the great draught of the sea that drew all towards the abyss, and afterwards he was sheltered from the first fury of the storm. But when the devouring wave rolled over the land and Númenor toppled to its fall, then he would have been overwhelmed and would have deemed it the lesser grief to perish, for no wrench of death could be more bitter than the loss and agony of that day; but the great wind took him, wilder than any wind that Men had known, roaring from the west, and it swept his ships far away; and it rent their sails and snapped their masts, hunting the unhappy men like straws upon the water.

Nine ships there were: four for Elendil, and for Isildur three, and for Anárion two; and they fled before the black gale out of the twilight of doom into the darkness of the world. And the deeps rose beneath them in towering anger, and waves like unto mountains moving with great caps of writhen snow bore them up amid the wreckage of the clouds, and after many days cast them away upon the shores of Middle-earth. And all the coasts and seaward regions of the western world suffered great change and ruin in that time; for the seas invaded the lands, and shores foundered, and ancient isles were drowned, and new isles were uplifted; and hills crumbled and rivers were turned into strange courses.

Elendil and his sons after founded kingdoms in Middle-earth; and though their lore and craft was but an echo of that which had been ere Sauron came to Númenor, yet very great it seemed to the wild men of the world. And much is said in other lore of the deeds of the heirs of Elendil in the age that came after, and of their strife with Sauron that not yet was ended.

For Sauron himself was filled with great fear at the wrath of the Valar, and the doom that Eru laid upon sea and land. It was greater far than aught he had looked for, hoping only for the death of the Númenóreans and the defeat of their proud king. And Sauron, sitting in his black seat in the midst of the Temple, had laughed when he heard the trumpets of Ar-Pharazôn sounding for battle; and again he had laughed when he heard the thunder of the storm; and a third time, even as he laughed at his own thought, thinking what he would do now in the world, being rid of the Edain for ever, he was taken in the midst of his mirth, and his seat and his temple fell into the abyss. But Sauron was not of mortal flesh, and though he was robbed now of that shape in which he had wrought so great an evil, so that he could never again appear fair to the eyes of Men, yet his spirit arose out of the deep and passed as a shadow and a black wind over the sea, and came back to Middle-earth and to Mordor that was his home. There he took up again his great Ring in Barad-dûr, and dwelt there, dark and silent, until he wrought himself a new guise, an image of malice and hatred made visible; and the Eye of Sauron the Terrible few could endure.
