It befell in the days of Denethor, when he was steward of all Gondor, that there was a mighty Power in Mordor that held war against him long time. And the Power was called the Dark Lord Sauron. And so by means Denethor sent for his Palantir, and he strove with the Dark Lord.
In the meanwhile came in a good old man, and an ancient, clothed all in white, and there was no one knew whence he came. And with him he brought a young Ranger, both on foot, without sword or shield, save a scabbard hanging by his side.
Then the old man said unto Denethor, 'Sir, I bring here a young Ranger, the which is of kings' lineage, and of the kindred of Elendil of Numenor, whereby the marvels of this city, and of strange realms, shall be fully accomplished.'
