The Silmarillion - J. R. R. Tolkien [174]
It is said that the towers of Emyn Beraid were not built indeed by the Exiles of Númenor, but were raised by Gilgalad for Elendil, his friend; and the Seeing Stone of Emyn Beraid was set in Elostirion, the tallest of the towers. Thither Elendil would repair, and thence he would gaze out over the sundering seas, when the yearning of exile was upon him; and it is believed that thus he would at whiles see far away even the Tower of Avallónë upon Eressëa, where the Master-stone abode, and yet abides. These stones were gifts of the Eldar to Amandil, father of Elendil, for the comfort of the Faithful of Númenor in their dark days, when the Elves might come no longer to that land under the shadow of Sauron. They were called the Palantíri, those that watch from afar; but all those that were brought to Middle-earth long ago were lost.
Thus the Exiles of Númenor established their realms in Arnor and in Gondor; but ere many years had passed it became manifest that their enemy, Sauron, had also returned. He came in secret, as has been told, to his ancient kingdom of Mordor beyond the Ephel Dúath, the Mountains of Shadow, and that country marched with Gondor upon the east. There above the valley of Gorgoroth was built his fortress vast and strong, Barad-dûr, the Dark Tower; and there was a fiery mountain in that land that the Elves named Orod-ruin. Indeed for that reason Sauron had set there his dwelling long before, for he used the fire that welled there from the heart of the earth in his sorceries and in his forging; and in the midst of the Land of Mordor he had fashioned the Ruling Ring. There now he brooded in the dark, until he had wrought for himself a new shape; and it was terrible, for his fair semblance had departed for ever when he was cast into the abyss at the drowning of Númenor. He took up again the great Ring and clothed himself in power; and the malice of the Eye of Sauron few even of the great among Elves and Men could endure.
Now Sauron prepared war against the Eldar and the Men of Westernesse, and the fires of the Mountain were wakened again. Wherefore seeing the smoke of Orodruin from afar, and perceiving that Sauron had returned, the Númenóreans named that mountain anew Amon Amarth, which is Mount Doom. And Sauron gathered to him great strength of his servants out of the east and the south; and among them were not a few of the high race of Númenor. For in the days of the sojourn of Sauron in that land the hearts of well nigh all its people had been turned towards darkness. Therefore many of those who sailed east in that time and made fortresses and dwellings upon the coasts were already bent to his will, and they served him still gladly in Middle-earth. But because of the power of Gil-galad these renegades, lords both mighty and evil, for the most part took up their abodes in the southlands far away; yet two there were, Herumor and Fuinur, who rose to power among the Haradrim, a great and cruel people that dwelt in the wide lands south of Mordor beyond the mouths of Anduin.
When therefore Sauron saw his time he came with great force against the new realm of Gondor, and he took Minas Ithil, and he destroyed the White Tree of Isildur that grew there. But Isildur escaped, and taking with him a seedling of the Tree he went with his wife and his sons by ship down the River, and they sailed from the mouths
