Tolkien Calendar: The Great Years

Then Treebeard said farewell to each of them in turn, and he bowed three times slowly and with great reverence to Celeborn and Galadriel. 'It is long, long since we met by stock and stone. A vanimar, vanimálion nostari!' he said. 'It is sad that we should meet only thus at the ending. For the world is changing: I feel it in the water, I feel it in the earth, and I smell it in the air. I do not think we shall meet again.'

...The travelers now rode with more speed, and they made their way towards the Gap of Rohan; and Aragorn took leave of them at last close to that very plave where Pippin had looked into the Stone of Orthanc. The Hobbits were grieved at this parting; for Aragorn had never failed them and he had been their guide through many perils.

... 'And remember, dear friends of the Shire, that my realm lies also in the North, and I shall come there one day.'

Then Aragorn took leave of Celeborn and Galadriel; and the Lady said to him: 'Elfstone, through darkness you have come to your hope, and now have all your desire. Use well the days!'

But Celeborn said: 'Kinsman, farewell! May your doom be other than mine, and your treasure remain with you to the end!'

With that they parted, and it was the time of sunset; and when after a while they turned and looked back, they saw the King of the West sitting upon his horse with his knights about him; and the falling Sun shone upon them and made all their harness to gleam like red gold, and the white mantle of Aragorn was turned to flame. Then Aragorn took the green stone and held it up, and there came a green fire from his hand.
