§ Of the Noldor in Beleriand The Silmarillion

And Melian spoke then no more of these matters with Galadriel; but she told to King Thingol all that she had heard of the Silmarils. 'This is a great matter,' she said, 'greater indeed than the Noldor themselves understand; for the Light of Aman and the fate of Arda lie locked now in these things, the work of Fëanor, who is gone. They shall not be recovered, I foretell, by any power of the Eldar; and the world shall be broken in battles that are to come, ere they are wrested from Morgoth. See now! Fëanor they have slain, and many another, as I guess; but first of all the deaths they have brought and yet shall bring was Finwë your friend. Morgoth slew him, ere he fled from Aman.'
