Rķan, daughter of Belegund, was the wife of Huor, son of Galdor; and she was wedded to him two months before he went with Hśrin 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 Rķan 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)
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, Voronwė! I await you." The Unfinished Tales (Of Tuor and his Coming to Gondolin)
At last, in the year when Eärendil was seven years old, Morgoth was ready, and he loosed upon Gondolin his Balrogs, and his Orcs, and his wolves; and with them came dragons of the brood of Glaurung, and they were become now many and terrible. Of the deeds of desperate valour there done, by the chieftains of the noble houses and their warriors, and not least by Tuor, much is told in The Fall of Gondolin: of the battle of Ecthelion of the Fountain with Gothmog Lord of Balrogs in the very square of the King, where each slew the other, and of the defence of the tower of Turgon by the people of his household, until the tower was overthrown; and mighty was its fall and the fall of Turgon in its ruin.
Tuor sought to rescue Idril from the sack of the city, but Maeglin had laid hands on her, and on Eärendil; and Tuor fought with Maeglin on the walls, and cast him far out, and his body as it fell smote the rocky slopes of Amon Gwareth thrice ere it pitched into the flames below. Then Tuor and Idril led such remnants of the people of Gondolin as they could gather in the confusion of the burning down the secret way which Idril had prepared.
There was a dreadful pass, Cirith Thoronath it was named, the Eagles' Cleft, where beneath the shadow of the highest peaks a narrow path wound its way; on the right hand it was walled by a precipice, and on the left a dreadful fall leapt into emptiness. Along that narrow way their march was strung, when they were ambushed by Orcs, for Morgoth had set watchers all about the encircling hills; and a Balrog was with them. Then dreadful was their plight, and hardly would they have been saved by the valour of yellow-haired Glorfindel, chief of the House of the Golden Flower of Gondolin, had not Thorondor come timely to their aid.
Many are the songs that have been sung of the duel of Glorfindel with the Balrog upon a pinnacle of rock in that high place; and both fell to ruin in the abyss. (...) Then Thorondor bore up Glorfindel's body out of the abyss, and they buried him in a mound of stones beside the pass; and a green turf came there, and yellow flowers bloomed upon it amid the barrenness of stone, until the world was changed. The Silmarillion (chapter 23)
Then Tuor looked down upon the fair vale of Tumladen, set as a green jewel amid the encircling hills; and he saw far off upon the rocky height of Amon Gwareth Gondolin the great, city of seven names, whose fame and glory is mightiest in song of all dwellings of the Elves in the Hither Lands.
Then Tuor stood before Turgon son of Fingolfin, High King of the Noldor, and upon the King's right hand there stood Maeglin his sister-son, but upon his left hand sat Idril Celebrindal his daughter; and all that heard the voice of Tuor marvelled, doubting that this were in truth a Man of mortal race, for his words were the words of the Lord of Waters that came to him in that hour. And he gave warning to Turgon that the Curse of Mandos now hastened to its fulfilment, when all the works of the Noldor should perish; and he bade him depart, and abandon the fair and mighty city that he had built, and go down Sirion to the sea. But Turgon was become proud, and Gondolin as beautiful as a memory of Elven Tirion, and he trusted still in its secret and impregnable strength, though even a Vala should gainsay it (...) Maeglin spoke ever against Tuor in the councils of the King, and his words seemed the more weighty in that they went with Turgon's heart; and at the last he rejected the bidding of Ulmo and refused his counsel.
And Tuor remained in Gondolin, for its bliss and its beauty and the wisdom of its people held him enthralled; and he became mighty in stature and in mind, and learned deeply of the lore of the exiled Elves. Then the heart of Idril was turned to him, and his to her; and Maeglin's secret hatred grew ever greater, for he desired above all things to possess her, the only heir of the King of Gondolin.
The Silmarillion (chapter 23)
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.
