§ Of the Silmarils and the Unrest of the Noldor The Silmarillion

Now the Valar were sitting in council before their gates, fearing the lengthening of the shadows, when the messengers came from Formenos. At once Oromë and Tulkas sprang up, but even as they set out in pursuit messengers came from Eldamar, telling that Melkor had fled through the Calacirya, and from the hill of Túna the Elves had seen him pass in wrath as a thundercloud. And they said that thence he had turned northward, for the Teleri in Alqualondë had seen his shadow going by their haven towards Araman.
