Fёanor and the Noldor returned to Middle-earth and fought a war against Morgoth that lasted for centuries, during which Fёanor was slain. One Silmaril was recovered by Beren and Lúthien, and brought back by Eärendil the Mariner. Eventually, the Valar took pity on the people of Middle-earth and came themselves to destroy Morgoth. In the ensuing battle, Morgoth’s fortress of Thangorodrim at Angband was destroyed and the Great Enemy defeated. The Silmarils were recovered, but two were lost forever, one beneath the earth and one in the sea. The one that had been recovered by Beren and Lúthien was placed in the sky by Elbereth as a symbol of hope for the people of Middle-earth. At the beginning of the Second Age the Noldorin Elves were allowed to return to Valinor, but many chose to remain for a time in Middle-earth, becoming known as High Elves (see bookmark for page 104).
Note: Fёanor also created the palantírs, or seeing-stones, that will appear later in Lord of the Rings, and perfected the Tengwar script used by the elves (see bookmark for page 66).
