Now when it was known that Morgoth had escaped from Valinor and pursuit was unavailing, the Valar remained long seated in darkness in the Ring of Doom, and the Maiar and the Vanyar stood beside them and wept; but the Noldor for the most part returned to Tlrion and mourned for the darkening of their fair city. Through the dim ravine of the Calacirya fogs drifted in from the shadowy seas and mantled its towers, and the lamp of the Mindon burned pale in the gloom.
Then suddenly Feanor appeared in the city and called on all to come to the high court of the King upon the summit of Tuna; but the doom of banishment that had been laid upon him was not yet lifted, and he rebelled against the Valar. A great multitude gathered swiftly, therefore, to hear what he would say; and the hill and an the stairs and streets that climbed upon it were lit with the light of many torches that each one bore in hand. Feanor was a master of words, and his tongue had great power over hearts when he would use it; and that night he made a speech before the Noldor which they ever remembered. Fierce and few were his words, and filled with anger and pride; and hearing them the Noldor were stirred to madness. His wrath and his hate were given most to Morgoth, and yet well nigh all that he said came from the very lies of Morgoth himself; but he was distraught with grief for the slaying of his father, and with anguish for the rape of the Silmarils. He claimed now the kingship of all the Noldor, since Finwe was dead, and he scorned the decrees of the Valar.
'Why, O people of the Noldor,' he cried, 'why should we longer serve the jealous Valar, who cannot keep us nor even their own realm secure from their Enemy? And though he be now their foe, are not they and he of one kin? Vengeance calls me hence, but even were it otherwise I would not dwell longer in the same land with the kin of my father's slayer and of the thief of my treasure. Yet I am not the only valiant in this valiant people. And have ye not all lost your King? And what else have ye not lost, cooped here in a narrow land between the mountains and the sea?
. . . .
At length after long debate Feanor prevailed, and the greater part of the Noldor there assembled he set aflame with the desire of new things and strange countries. Therefore when Finarfin spoke yet again for heed and delay, a great shout went up: 'Nay, let us be gone!' And straightway Feanor and his sons began to prepare for the marching forth.
