Idril Celebrindal was the only child of Turgon, whose wife Elenwë perished in the crossing of the Helcaraxë. Together with Angrod's son Orodreth she was one of the two Ñoldor in the third generation to come into exile. Idril was loved in secret by her cousin Maeglin, the son of Eöl the Dark Elf and Aredhel, Turgon's sister, but she scorned his advances because of his dark character, as well as the fact that they were too closely related.
When Tuor, son of Huor arrived in Gondolin, Idril fell in love with him. Because Turgon had grown to love Tuor as a son (as he had his father before), he allowed Idril and Tuor to wed, thus bringing about the second union of Men and Elves, after Beren and Lúthien.
Being far-sighted she sensed danger, she encouraged Tuor to prepare a secret passage under the city so that if the city was attacked survivors could safely escape the city. After the Fall of Gondolin, Idril and Tuor became leaders of the exiles at the Mouths of Sirion in the West Beleriand in the region of Arvernien, where they also received Elwing daughter of Dior son of Beren and Lúthien.
When Tuor grew old he and Idril departed in his ship for the West. It is believed by the elves and the Dúnedain that Idril and Tuor safely arrived in Valinor, bypassing the Ban of the Valar, and that Tuor was reckoned in the kindred of the Elves, so that both she and her husband now live in Valinor.
The name Idril was a Sindarized form of her Quenya name Itarillë (or Itarildë), which means "sparkling brilliance". Celebrindal was also a Sindarin word attached to her name which meant "silver-foot" due to the fact that she always walked in her barefeet.
