In that time the last of the Noldor set sail from the Havens and left Middle-earth for ever. And latest of all the Keepers of the Three Rings rode to the Sea, and Master Elrond took there the ship that Círdan had made ready. In the twilight of autumn it sailed out of Mithlond, until the seas of the Bent World fell away beneath it, and the winds of the round sky troubled it no more, and borne upon the high airs above the mists of the world it passed into the Ancient West, and an end was come for the Eldar of story and of song.

Then Gil-galad and Elendil passed into Mordor and encompassed the stronghold of Sauron; and they laid siege to it for seven years, and suffered grievous loss by fire and by the darts and bolts of the Enemy, and Sauron sent many sorties against them.

It was in Eregion that the counsels of Sauron were most gladly received, for in that land the Noldor desired ever to increase the skill and subtlety of their works. Moreover they were not at peace in their hearts, since they had refused to return into the West, and they desired both to stay in Middle-earth, which indeed they loved, and yet to enjoy the bliss of those that had departed. Therefore they hearkened to Sauron, and they learned of him many things, for his knowledge was great. In those days the smiths of Ost-in-Edhil surpassed all that they had contrived before; and they took thought, and they made Rings of Power.

Thus in after days, what by the voyages of ships, what by lore and star-craft, the kings of Men knew that the world was indeed made round, and yet the Eldar were permitted still to depart and to come to the Ancient West and to Avallónë, if they would. Therefore the loremasters of Men said that a Straight Road must still be, for those that were permitted to find it. And they taught that, while the new world fell away, the old road and the path of the memory of the West still went on, as it were a mighty bridge invisible that passed through the air of breath and of flight (which were bent now as the world was bent), and traversed Ilmen which flesh unaided cannot endure, until it came to Tol Eressëa, the Lonely Isle, and maybe even beyond, to Valinor, where the Valar still dwell and watch the unfolding of the story of the world. And tales and rumours arose along the shores of the sea concerning mariners and men forlorn upon the water who, by some fate or grace or favour of the Valar, had entered in upon the Straight Way and seen the face of the world sink below them, and so had come to the lamplit quays of Avallónë, or verily to the last beaches on the margin of Aman, and there had looked upon the White Mountain, dreadful and beautiful, before they died.

Akallabêth

And men saw his sails coming up out of the sunset, dyed as with scarlet and gleaming with red and gold, and fear fell upon the dwellers by the coasts, and they fled far away. But the fleet came at last to that place that was called Umbar, where was the mighty haven of the Númenóreans that no hand had wrought. Empty and silent were all the lands about when the King of the Sea marched upon Middle-earth. For seven days he journeyed with banner and trumpet, and he came to a hill, and he went up, and he set there his pavilion and his throne; and he sat him down in the midst of the land, and the tents of his host were ranged all about him, blue, golden, and white, as a field of tall flowers. Then he sent forth heralds, and he commanded Sauron to come before him and swear to him fealty.

Akallabêth

Then the Edain set sail upon the deep waters, following the Star; and the Valar laid a peace upon the sea for many days, and sent sunlight and a sailing wind, so that the waters glittered before the eyes of the Edain like rippling glass, and the foam flew like snow before the stems of their ships. But so bright was Rothinzil that even at morning Men could see it glimmering in the West, and in the cloudless night it shone alone, for no other star could stand beside it. And setting their course towards it the Edain came at last over leagues of sea and saw afar the land that was prepared for them, Andor, the Land of Gift, shimmering in a golden haze.
Akallabêth

Softly in the gloom they heard the birds
Singing afar in Nargothrond,
The sighting of the Sea beyond,
Beyond the western world, on sand,
On sand of pearls on Elvenland.
Then in the doom gathered; darkness growing
In Valinor, the red blood flowing
Beside the Sea, where the Noldor slew
The Foamriders, and stealing drew
Their white ships with their white sails
From lamplit havens. The wind wails,
The wolf howls. The ravens flee.
The ice mutters in the mouths of the Sea.
The captives sad in Angband mourn.
Thunder rumbles, the fires burn--
And Finrod fell before the throne.

"Of Beren and Lúthien"

Now the forest of Dorthonion rose southward into mountainous moors; and in the east of those highlands there lay a lake, Tarn Aeluin, with wild heaths about it, and all that land was pathless and untamed, for even in the days of the Long Peace none had dwelt there. But the waters of Tarn Aeluin were held in reverence, for they were clear and blue by day and by night were a mirror for the stars; and it was said that Melian herself had hallowed that water in the days of old. Thither Barahir and his outlaws withdrew, and there made their lair, and Morgoth could not discover it.

In that wood in ages past Melian walked in the twilight of Middle-earth when the trees were young, and enchantment lay upon it still. But now the trees of Nan Elmoth were the tallest and darkest in all Beleriand, and there the sun never came; and there Eöl dwelt, who was named the Dark Elf. Of old he was of the kin of Thingol, but he was restless and ill at ease in Doriath, and when the Girdle of Melian was set about the Forest of Region where he dwelt he fled thence to Nan Elmoth. There he lived in deep shadow, loving the night and the twilight under the stars.
"Of Maeglin"

But as the host of Fingolfin marched into Mithrim the Sun rose flaming in the West; and Fingolfin unfurled his blue and silver banners, and blew his horns, and flowers sprang beneath his marching feet, and the ages of the stars were ended.
