Beren back his life and allowed Lúthien to renounce her immortality and live as a mortal in Middle-earth. Thus, after they died, they would share the same fate. The Noldor, emboldened by the couple's feat, attacked Melkor again, with a great army of Elves, Dwarves, and Men. But Melkor had secretly corrupted some of the Men, and the Elvish host was utterly defeated in the Fifth Battle. Húrin and Huor were brothers; Huor died in battle, but Melkor captured Húrin and cursed him to watch the downfall of his kin. Húrin's son, Túrin Turambar, was sent to Doriath, leaving his mother and unborn sister behind in his father's kingdom of Dor-lómin (which was overrun by the enemy). Túrin achieved many great deeds of valour, the greatest being the defeat of the dragon Glaurung. Despite his heroism, however, Túrin fell under the curse of Melkor, which led him to unwittingly murder his friend Beleg and marry and impregnate his sister Nienor Níniel, who had lost her memory through Glaurung's enchantment. Before their child was born, the dragon lifted the enchantment. Nienor took her own life, and Túrin threw himself upon his sword. Huor's son, Tuor, became involved in the fate of the hidden kingdom of Gondolin. He married Idril, daughter of Turgon, Lord of Gondolin (the second union between Elves and Men). When Gondolin fell, betrayed by the king's nephew Maeglin, Tuor saved many of its inhabitants. All the Elvish kingdoms in Beleriand fell, and the refugees fled to a haven by the sea created by Tuor. The son of Tuor and Idril Celebrindal, Eärendil the Half-elven, was betrothed to Elwing, herself descended from Beren and Lúthien. Elwing brought Eärendil Beren's Silmaril; the jewel enabled Eärendil to cross the sea to Aman to seek help from the Valar. They obliged, defeating Melkor and destroying Angband, though most of Beleriand sank into the sea, and expelled Melkor from Arda. This ended the First Age of Middle-earth. The last two Silmarils were seized by Fëanor's sons, Maedhros and Maglor. However, because of the evil way the brothers had gained the Silmarils, they were no longer worthy to receive them, and the Silmarils burnt their hands. In anguish, Maedhros killed himself by leaping into a fiery chasm with his Silmaril, while Maglor threw his jewel into the sea and spent the rest of his days wandering along the shores of the world, singing his
