Tar-Palantír was the twenty-fourth and penultimate King of Númenor. Though his father Ar-Gimilzôr despised the elves and the Valar, his mother Inzilbêth taught him the ways of the Faithful in secret. Gimilzôr thus would rather have had his second son Gimilkhâd inherit, but he could not change the laws of the kingdom to exclude Inziladûn, nor convince him to cede the crown to his brother.
When Tar-Palantír took the scepter, he returned as best he could to the ways of the Valar, taking his name in Quenya and nurturing the White Tree, for he foresaw that its death would spell the end of the line of kings. Yet the King’s Men were still a powerful force in Númenor, led by Gimilkhâd himself, and this attempt to repent from wickedness was met with great backlash from his people and little sympathy from the Valar. Filled with sorrow, Tar-Palantír began to spend more time in the tower of Tar-Minastir, gazing West in the vain hope of catching a glimpse of Tol Eressëa or an elven ship.
Late in his life, Palantír fell in love with a maiden of his court named Nimirrôth. Though her parents were not of the Faithful, neither were they of the King’s Men, and they loved the old stories of the elves, naming her in their memory. Nimirrôth was flattered by the attention of the king’s heir, but her love was focused ever on his brother Gimilkhâd. Yet Gimilkhâd had already wed the leader of the King’s Women, Zôrzimril, and was indifferent to her.
Nimirrôth thus agreed to be Tar-Palantír’s queen, taking the name Tári-Eldafallië which her husband gave her. Though she still loved Gimilkhâd, she bore Palantír a daughter, Míriel, a year before Gimilkhâd and Zôrzimril had a son, Pharazôn. After her husband was crowned King, Nimirrôth broke down and confessed her feelings to Gimilkhâd, and though he did not love her he saw an opportunity here to manipulate the Queen of Númenor into his favor. They began an affair, and Nimirrôth, who had before cared little for politics, soon became a secret supporter of the King’s Men.
Gimilkhâd died before his plans could come to fruition, but Nimirrôth, Zôrzimril, and Pharazôn would work together in his name to bring down the Faithful once and for all. Pharazôn had gone to Middle-earth as a conqueror and warrior against Sauron, but returned Elenna to take up his father’s mantle as the leader of the King’s Men. When Tar-Palantír died, Míriel should have inherited the scepter and become the fourth Ruling Queen of Númenor, but she found herself betrayed by her mother and forced into marriage with her cousin, who took the throne as Ar-Pharazôn and renamed her Ar-Zimraphêl, using the prefix Ar rather than Arî to emphasize his right to rule as the husband of the last king’s heir.
Ar-Pharazôn soon returned to Middle-earth with a great force to humble Sauron and claim the kingship of all Men. When Sauron perceived that he could not defeat the Númenóreans in battle, he feigned humility and allowed Pharazôn to take him as a servant to Númenor where he quickly became chief advisor to the king, known as Zigûr to the people. He corrupted Pharazôn’s heart even further by encouraging him to worship Melkor, Lord of Darkness.
When Isildur of Andúnië stole a fruit from the White Tree, Pharazôn was angered and at the advice of Zigûr he tore the tree down and burned it in a great temple he had constructed to Melkor. He sacrificed many of the Faithful upon the flames in the hope that Melkor would grant him and his supporters immortality, and this practice spread to Middle-earth. Yet age still crept upon Pharazôn, younger than it had any of his predecessors, and he became ever more desperate to escape death.
Zigûr steered the king toward building a great armament to attack Aman itself, preaching that only after conquering Valinor and defeating the Valar could he achieve his goal. At last Ar-Pharazôn set sail, but upon setting foot in the city of Tirion the Valar called upon Eru Ilúvatar for aid. Seeing the wickedness and pride of the Númenóreans, Eru broke the world and made it round, preventing Men from ever again reaching Valinor. In the destruction, Pharazôn’s fleet was destroyed and buried in the underground Caves of the Forgotten, where he and his soldiers await the Dagor Dagorath where they will face Morgoth in order to repent for their sins.
At this time, Númenor was drowned beneath the sea with all its people save those Faithful who had escaped in nine ships led by Elendil of Andúnië and his sons. Zigûr was consumed by the storm and perished laughing, and though he would return to menace Middle-earth once more, he was diminished ever after and could no longer take a fair form.
As the waves rose, Tar-Míriel ascended the peak of the Meneltarma, the highest point on Elenna, and was thus the last Númenórean to take breath upon its soil before she, too, was drowned in the bosom of the vengeful sea.
