Huor's son, Tuor, became involved in the fate of the hidden Noldorin kingdom of Gondolin. He married Idril, daughter of Turgon, Lord of Gondolin (the second union between Elves and Men). When Gondolin fell, betrayed from within by the king's traitorous nephew Maeglin, Tuor saved many of its inhabitants. All the Elvish kingdoms in Beleriand eventually 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 the Silmaril of Beren and Lúthien; the jewel enabled Eärendil to cross the sea to Aman to seek help from the Valar. The Valar obliged, attacking and defeating Melkor and completely 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 surviving sons, Maedhros and Maglor. However, because of all the evil deeds the brothers had committed in their quest to gain the Silmarils, they were no longer counted worthy to receive them, so 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 grief.
