as the Ringwraiths. He built a stronghold called Barad-dûr and secretly forged the One Ring in the fires of Mount Doom to control the other rings and their bearers. Celebrimbor, a grandson of Fëanor, forged three mighty rings on his own: Vilya, possessed first by the Elven king Gil-galad, then by Elrond; Nenya, wielded by Galadriel; and Narya, given by Celebrimbor to Círdan, who gave it to Gandalf. As soon as Sauron put on the One Ring, the Elves realized that they had been betrayed and removed the Three (Sauron eventually obtained the Seven and the Nine. While he was unable to suborn the Dwarf ringbearers, he had more success with the Men who bore the Nine; they became the Nazgûl or Ringwraiths). Sauron then made war on the elves and nearly destroyed them utterly during the Dark Years, but when it seemed defeat was imminent, the Númenóreans joined the battle and completely crushed the forces of Sauron. Sauron never forgot the ruin brought on his armies by the Númenóreans, and made it his goal to destroy them. Towards the end of the age, the Númenóreans became increasingly haughty. Now they sought to dominate other men and to establish kingdoms. Centuries after Tar-Minastir's engagement, when Sauron had largely recovered, Ar-Pharazôn, the last and most powerful of the Kings of Númenor, humbled Sauron – his armies deserting in the face of Númenor's might – and brought him to Númenor as a hostage, although this was Sauron's goal. At this time still beautiful in appearance, Sauron gained Ar-Pharazôn's trust and became high priest in the cult of Melkor. At this time, the Faithful (who still worshipped the one god, Eru Ilúvatar), were persecuted openly by those called the King's Men, and were sacrificed in the name of Melkor. Eventually, Sauron convinced Ar-Pharazôn to invade Aman, promising him that he would thus obtain immortality. Amandil, chief of the Faithful, sailed westward to warn the Valar. His son Elendil and grandsons Isildur and Anárion prepared to flee eastwards, taking with them a seedling of the White Tree of Númenor before Sauron destroyed it, and the palantíri, gifts of the elves. When the King's forces set foot on Aman, the Valar laid down their guardianship of the world and called on Ilúvatar to intervene. The world was changed into a sphere and the continent of Aman was removed, although a sailing route from Middle-earth to
