The Silmarillion

Now while the city of Gondolin was building in secret, Finrod Felagund wrought in the deep places of Nargothrond; but Galadriel his sister dwelt, as has been told, in Thingol's realm in Doriath. And at times Melian and Galadriel would speak together of Valinor and the bliss of old; but beyond the dark hour of the death of the Trees Galadriel would not go, but ever fell silent. And on a time Melian said: 'There is some woe that lies upon you and your kin. That I can see in you, but all else is hidden from me; for by no vision or thought can I perceive anything that passed or passes in the West: a shadow lies over all the land of Aman, and reaches far out over the sea. Why will you not tell me more?'

'For that woe is past,' said Galadriel; 'and I would take what joy is here left, untroubled by memory. And maybe there is woe enough yet to come, though still hope may seem bright.'

Then Melian looked in her eyes, and said: 'I believe not that the Noldor came forth as messengers of the Valar, as was said at first: not though they came in the very hour of our need. For they speak never of the Valar, nor have their high lords brought any message to Thingol, whether from Manwe, or Ulmo, or even from Olwe the King's brother, and his own folk that went over the sea. For what cause, Galadriel, were the high people of the Noldor driven forth as exiles from Aman? Or what evil lies on the sons of Feanor that they are so haughty and so fell? Do I not strike near the truth?' "Near,' said Galadriel; 'save that we were not driven forth, but came of our own will, and against that of the Valar. And through great peril and in despite of the Valar for this purpose we came: to take vengeance upon Morgoth, and regain what he stole.'

Then Galadriel spoke to Melian of the Silmarils, and of the slaying of King Finwe at Formenos: but still she said no word of the Oath, nor of the Kinslaying, nor of the burning of the ships at Losgar. But Melian said: 'Now much you tell me, and yet more I perceive. A darkness you would cast over the long road from Tirion, but I see evil there, which Thingol should learn for his guidance.'

'Maybe,' said Galadriel; 'but not of me.'

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 Feanor, 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! Feanor they have slain, and many another, as I guess; but first of all the deaths they have brought and yet shall bring was Finwe your friend. Morgoth slew him, ere he fled from Aman.'

Then Thingol was silent, being filled with grief and foreboding; but at length he said: 'Now at last I understand the coming of the Noldor out of the West, at which I wondered much before. Not to our aid did they come (save by chance); for those that remain in Middle-earth the Valar will leave to their own devices, until the uttermost need. For vengeance and redress of their loss the Noldor came. Yet all the more sure shall they be as allies against Morgoth, with whom it is not now to be thought that they shall ever make treaty.'

But Melian said: 'Truly for these causes they came; but for others also. Beware of the sons of Feanor! The shadow of the wrath of the Valar lies upon them; and they have done evil, I perceive, both in Aman and to their own kin. A grief but lulled to sleep lies between the princes of the Noldor.'

And Thingol answered: 'What is that to me? Of Feanor I have heard but report, which makes him great indeed.

Of his sons I hear little to my pleasure; yet they are likely to prove the deadliest foes of our foe.'

Their swords and their counsels shall have two edges,' I said Melian; and afterwards they spoke no more of this matter.

It was not long before whispered tales began to pass among the Sindar concerning the deeds of the Noldor ere they came to Beleriand. Certain it is whence they came, and the evil truth was enhanced and poisoned by lies; but the Sindar were yet unwary and trustful of words, and (as may well be thought) Morgoth chose them for this first assault of his malice, for they knew him not. And Cirdan, hearing these dark tales, was troubled; for he was wise, and perceived swiftly that true or false they were put about at this time through malice, though the malice he deemed was that of the princes of the Noldor, because of the jealousy of their houses. Therefore he sent messengers to Thingol to tell all that he had heard.

It chanced that at that time the sons of Finarfin were again the guests of Thingol, for they wished to see their sister Galadriel. Then Thingol, being greatly moved, spoke in anger to Finrod, saying: 'Ill have you done to me, kinsman, to conceal so great matters from me. For now I have learned of all the evil deeds of the Noldor.'

But Finrod answered: 'What ill have I done yon, lord? Or what evil deed have the Noldor done in all your realm to grieve you? Neither against your kinship nor against any of your people have they thought evil or done evil.'

'I marvel at you, son of Earwen,' said Thingol, 'that you would come to the board of your kinsman thus redhanded from the slaying of your mothers kin, and yet say naught in defence, nor yet seek any pardon!'

Then Finrod was greatly troubled, but he was silent, for he could not defend himself, save by bringing charges against the other princes of the Noldor; and that he was loath to do before Thingol. But in Angrod's heart the memory of the words of Caranthir welled up again in bitterness, and he cried: 'Lord, I know not what lies you have heard, nor whence; but we came not red-handed. Guiltless we came forth, save maybe of folly, to listen to the words of fell Feanor, and become as if besotted with wine, and as briefly. No evil did we do on our road, but suffered ourselves great wrong; and forgave it. For this we are named tale-bearers to you and treasonable to the Noldor: untruly as you know, for we have of our loyalty been silent before you, and thus earned your anger. But now these charges are no longer to be borne, and the truth yon shall know.'

Then Angrod spoke bitterly against the sons of Feanor, telling of the blood at Alqualonde, and the Doom of Mandos, and the burning of the ships at Losgar. And he cried: 'Wherefore should we that endured the Grinding Ice bear the name of kinslayers and traitors?'

'Yet the shadow of Mandos lies on you also,' said Melian. But Thingol was long silent ere he spoke. 'Go now!' he said. 'For my heart is hot within me. Later you may return, if you will; for I will not shut my doors for ever against you, my kindred, that were ensnared in an evil that you did not aid. With Fingolfin and his people also I will keep friendship, for they have bitterly atoned for such ill as they did. And in our hatred of the Power that wrought all this woe our griefs shall be lost. But hear my words! Never again in my ears shall be heard the tongue of those who slew my kin in  Alqualonde! Nor in all my realm shall it be openly spoken, while my power endures. All the Sindar shall hear my command that they shall neither speak with the tongue of the Noldor nor answer to it. And all such as use it shall be held slayers of kin and betrayers of kin unrepentant.'
