Beneath the long slopes of Mount Taras in bygone days Turgon had dwelt in the halls of Vinyamar, eldest of all the works of stone that the Noldor built in the lands of their exile. There it still stood, desolate but enduring, high upon great terraces that looked towards the sea. (...) Tuor went up the wide stairs, now half-hidden in thrift and campion, and he passed under the mighty lintel and entered the shadows of the house of Turgon; and he came at last to a high-pillared hall. (...) Then Tuor marvelling saw that on the wall behind the throne were hung a shield and a great hauberk, and a helm and a long sword in a sheath. The hauberk shone as it were wrought of silver untarnished, and the sunbeam gilded it with sparks of gold. But the shield was of a shape strange to Tuor's eyes, for it was long and tapering; and its field was blue, in the midst of which was wrought an emblem of a white swan's wing. Then Tuor spoke, and his voice rang as a challenge in the roof: 'By this token I will take these arms unto myself, and upon myself whatsoever doom they bear.'
Now Tuor felt his feet drawn to the sea-strand, and he went down by long stairs to a wide shore upon the north side of Taras-ness (...). And Tuor stood upon the shore, and the sun was like a smoky fire behind the menace of the sky; and it seemed to him that a great wave rose far off and rolled towards the land, but wonder held him, and he remained there unmoved. And the wave came towards him, and upon it lay a mist of shadow. Then suddenly as it drew near it curled, and broke, and rushed forward in long arms of foam; but where it had broken there stood dark against the rising storm a living shape of great height and majesty. Then Tuor bowed in reverence, for it seemed to him that he beheld a mighty king. A tall crown he wore like silver, from which his long hair fell down as foam glimmering in the dusk. (...) And thereupon Ulmo lifted up a mighty horn, and blew upon it a single great note, to which the roaring of the storm was but a wind-flaw upon a lake. And as he heard that note, and was encompassed by it, and filled with it, it seemed to Tuor that the coasts of Middle-earth vanished, and he surveyed all the waters of the world in a great vision: from the veins of the lands to the mouths of the rivers, and from the strands and estuaries out into the deep.
He awoke at length in the grey light, and arose, and left the high seat (...). And Tuor looked down from the lowest terrace and saw, leaning against its wall among the stones and the sea-wrack, an Elf, clad in a grey cloak sodden with the sea. Silent he sat, gazing beyond the ruin of the beaches out over the long ridges of the waves. All was still, and there was no sound save the roaring of the surf below. As Tuor stood and looked at the silent grey figure he remembered the words of Ulmo, and a name untaught came to his lips, and he called aloud: "Welcome, Voronwë! I await you." The Unfinished Tales (Of Tuor and his Coming to Gondolin)
Rían, daughter of Belegund, was the wife of Huor, son of Galdor; and she was wedded to him two months before he went with Húrin his brother to the Nirnaeth Arnoediad. When no tidings came of her lord she fled into the wild; but she was aided by the Grey-elves of Mithrim, and when her son Tuor was born they fostered him. Then Rían departed from Hithlum, and going to the Haudh-en-Ndengin she laid herself down upon it and died."
"Tuor was taken to foster by Annael of the Grey-elves, who yet lived in those hills. Now when Tuor was sixteen years old the Elves were minded to leave the caves of Androth where they dwelt, and to make their way secretly to the Havens of Sirion in the distant south; but they were assailed by Orcs and Easterlings before they made good their escape, and Tuor was taken captive and enslaved by Lorgan, chief of the Easterlings of Hithlum. For three years he endured that thraldom, but at the end of that time he escaped; and returning to the caves of Androth he dwelt there alone, and did such great hurt to the Easterlings that Lorgan set a price upon his head. The Silmarillion (chapter 21 & 23)
But when Tuor had lived thus in solitude as an outlaw for four years, Ulmo set it in his heart to depart from the land of his fathers, for he had chosen Tuor as the instrument of his designs; and leaving once more the caves of Androth he went westwards across Dor-lómin. But even as dim dusk came on the third day of his journey, Tuor found before him a wall of rock, and there was an opening therein like a great arch; and the stream passed in and was lost. Then Tuor was dismayed, and he said: "So my hope has cheated me! The sign in the hills has led me only to dark end in the midst of the land of my enemies." But even as the light of the coming sun shone pale in the far mists of Mithrim, Tuor heard voices, and looking down he saw in amazement two Elves that waded in the shallow water. So he found Annon-in-Gelydh, the Gate of the Noldor, which the people of Turgon built when they dwelt in Nevrast long years before.
Thence a dark tunnel led beneath the mountains, and issued into Cirith Ninniach, the Rainbow Cleft, through which a turbulent water ran towards the western sea. The sun rose behind his back and set before his face, and where the water foamed among the boulders or rushed over sudden falls, at morning and evening rainbows were woven across the stream. High hills now marched on either side, and fresh waters spilled from them into Cirith Ninniach over shimmering falls. Then he lifted up his voice, and plucked the strings of his harp, and above the noise of the water the sound of his song and the sweet thrilling of the harp were echoed in the stone and multiplied.
And Tuor came into Nevrast, and looking upon Belegaer the Great Sea he was enamoured of it, and the sound of it and the longing for it were ever in his heart and ear, and an unquiet was on him that took him at last into the depths of the realms of Ulmo. Then he dwelt in Nevrast alone, and the summer of that year passed, and the doom of Nargothrond drew near; but when the autumn came he saw seven great swans flying south, and he knew them for a sign that he had tarried overlong, and he followed their flight along the shores of the sea. The Silmarillion (chapter 23), The Unfinished Tales (Of Tuor and his Coming to Gondolin)
Thus led by Tuor son of Huor the remnant of Gondolin passed over the mountains, and came down into the Vale of Sirion; and fleeing southward by weary and dangerous marches they came at length to Nan-tathren, the Land of Willows, for the power of Ulmo yet ran in the great river, and it was about them. There they rested a while, and were healed of their hurts and weariness; but their sorrow could not be healed. And they made a feast in memory of Gondolin and of the Elves that had perished there, the maidens, and the wives, and the warriors of the King; and for Glorfindel the beloved many were the songs they sang, under the willows of Nan-tathren in the waning of the year. There Tuor made a song for Eärendil his son, concerning the coming of Ulmo the Lord of Waters to the shores of Nevrast aforetime; and the sea-longing woke in his heart, and in his son's also. Therefore Idril and Tuor departed from Nan-tathren, and went southwards down the river to the sea; and they dwelt there by the mouths of Sirion, and joined their people to the company of Elwing Dior's daughter, that had fled thither but a little while before.
In those days Tuor felt old age creep upon him, and ever a longing for the deeps of the Sea grew stronger in his heart. Therefore he built a great ship, and he named it Eärrámë, which is Sea-Wing; and with Idril Celebrindal he set sail into the sunset and the West, and came no more into any tale or song. But in after days it was sung that Tuor alone of mortal Men was numbered among the elder race, and was joined with the Noldor, whom he loved; and his fate is sundered from the fate of Men.
Bright Eärendil was then lord of the people that dwelt nigh to Sirion's mouths; and he took to wife Elwing the fair, and she bore to him Elrond and Elros, who are called the Half-elven. Yet Eärendil could not rest, and his voyages about the shores of the Hither Lands eased not his unquiet. Two purposes grew in his heart, blended as one in longing for the wide Sea: he sought to sail thereon, seeking after Tuor and Idril who returned not; and he thought to find perhaps the last shore, and bring ere he died the message of Elves and Men to the Valar in the West, that should move their hearts to pity for the sorrows of Middle-earth.
Great was the sorrow of Eärendil and Elwing for the ruin of the havens of Sirion, and the captivity of their sons, and they feared that they would be slain. (...) Yet Eärendil saw now no hope left in the lands of Middle-earth, and he turned again in despair and came not home, but sought back once more to Valinor with Elwing at his side.
