§ Of the Flight of the Noldor The Silmarillion

Many there grieved for the anguish of Fëanor, but his loss was not his alone; and Yavanna wept by the mound, in fear that the Darkness should swallow the last rays of the Light of Valinor for ever. For though the Valar did not yet understand fully what had befallen, they perceived that Melkor had called upon some aid that came from beyond Arda. The Silmarils had passed away, and all one it may seem whether Fëanor had said yea or nay to Yavanna; yet had he said yea at the first, before the tidings came from Formenos, it may be that his after deeds would have been other than they were. But now the doom of the Noldor drew near.
