"At the doors of the Houses many were already gathered to see Aragorn, and they followed after him; and at last when he had supped, men came and prayed that he would heal their kinsmen or their friends whose lives were in peril through hurt or wound, or who lay under the Black Shadow. And Aragorn arose and went out, and he sent for the sons of Elrond, and together they laboured far into the night. And word went through the City: 'The King is come again indeed.' And they named him Elf-stone, because of the green stone that he wore, and so the name which it was foretold at his birth that he should bear was chosen for him by his own people.

And when he could labour no more, he cast his cloak about him, and he slipped out of the City, and he went to his tent just ere dawn and slept for a little. And in the morning the banner of Dol Amroth, a white ship like a a swan upon blue water, floated from the Tower, and men looked up and wondered if the coming of the King had been but a dream."
