Ever most vigilant was Mithrandir, and he it was that most doubted the darkness in Mirkwood, for though many deemed that it was wrought by the Ringwraiths, he feared that it was indeed the first shadow of Sauron returning; and he went to Dol Guldur, and the Sorcerer fled from him, and there was a watchful peace for a long while. But at length the Shadow returned and its power increased; and in that time was first made the Council of the Wise that is called the White Council, and therein were Elrond and Galadriel and Cirdan, and other lords of the Eldar, and with them were Mithrandir and Curunir. And Curunir (that was Saruman the White) was chosen to be their chief, for he had most studied the devices of Sauron of old. Galadriel indeed had wished that Mithrandir should be the Lead of the Council, and Saruman begrudged them that, for his pride and desire of mastery was grown great; but Mithrandir refused the office, since he would have no ties and no allegiance, save to those who sent him, and he would abide in no place nor be subject to any summons. But Saruman now began to study the lore of the Rings of Power, their making and their history.
Now the Shadow grew ever greater, and the hearts of Elrond and Mithrandir darkened. Therefore on a time Mithrandir at great peril went again to Dol Guldur and the pits of the Sorcerer, and he discovered the truth of his fears, and escaped. And returning to Elrond he said: 'True, alas, is our guess. This is not one of the Ulairi, as many have long supposed. It is Sauron himself who has taken shape again and now grows apace; and he is gathering again all the Rings to his hand; and he seeks ever for news of the One, and of the Heirs of Isildur, if they live still on earth.'
And Elrond answered: 'In the hour that Isildur took the Ring and would not surrender it, this doom was wrought, that Sauron should return.'
'Yet the One was lost,' said Mithrandir, 'and while it still lies hid, we can master the Enemy, if we gather our strength and tarry not too long.'
Then the White Council was summoned; and Mithrandir urged them to swift deeds, but Curunir spoke against him, and counselled them to wait yet and to watch. 'For I believe not,' said he, 'that the One will ever be found again in Middle-earth. Into Anduin it fell, and long ago, I deem, it was rolled to the Sea. There it shall lie until the end, when all this world is broken and the deeps are removed.'
Therefore naught was done at that time, though Elrond's heart misgave him, and he said to Mithrandir: 'Nonetheless I forbode that the One will yet be found, and then war will arise again, and in that war this Age will be ended. Indeed in a second darkness it will end, unless some strange chance deliver us that my eyes cannot see.' 'Many are the strange chances of fee world,' said Mithrandir, 'and help oft shall come from the hands of the weak when the Wise falter.'
Thus the Wise were troubled, but none as yet perceived that Curunir had turned to dark thoughts and was already a traitor in heart: for he desired that he and no other should find the Great Ring, so that he might wield it himself and order all the world to his will Too long he had studied the ways of. Sauron in hope to defeat him, and now he envied him as a rival rather than hated his works. And he deemed that the Ring, which was Sauron's, would seek for its master as he became manifest once more; but if he were driven out again, then it would lie hid. Therefore he was willing to play with peril and let Sauron be for a time, hoping by his craft to forestall both his friends and the Enemy, when the Ring should appear.
He set a watch upon the Gladden Fields; but soon he discovered that the servants of Dol Guldur were searching all the ways of the River in that region. Then he perceived that Sauron also had learned of the manner of Isildur's end, and he grew afraid and withdrew to Isengard and fortified it; and ever he probed deeper into the lore of the Rings of Power and the art of their forging. But he spoke of none of this to the Council, hoping still that he might be the first to hear news of the Ring. He gathered a great host of spies, and many of these were birds; for Radagast lent him his aid, divining naught of his treachery, and deeming that this was but part of the watch upon the Enemy.
But ever the shadow in Mirkwood grew deeper, and to Dol Guldur evil things repaired out of all the dark places of the world; and they were united again under one will, and their malice was directed against the Elves and the survivors of Numenor. Therefore at last the Council was again summoned and the lore of the Rings was much debated; but Mithrandir spoke to the Council, saying: 'It is not needed that the Ring should be found, for while it abides on earth and is not unmade, still the power that it holds will live, and Sauron will grow and have hope. The might of the Elves and the Elf-friends is less now than of old. Soon he will be too strong for you, even without the Great Ring; for he rules the Nine, and of the Seven he has recovered three. We must strike.'
To this Curunir now assented, desiring that Sauron should be thrust from Dol Guldur, which was nigh to the River, and should have leisure to search there no longer. Therefore, for the last time, he aided the Council, and they put forth their strength; and they assailed Dol Guldur, and drove Sauron from his hold, and Mirkwood for a brief while was made wholesome again.
But their stroke was too late. For the Dark Lord had foreseen it, and he had long prepared all his movements; and the Ulairi, his Nine Servants, had gone before him to make ready for his coming. Therefore his flight was but a feint, and he soon returned, and ere the Wise could prevent him he re-entered his kingdom in Mordor and reared once again the dark towers of Barad-dur. And in that year the White Council met for the last time, and Curunir withdrew to Isengard, and took counsel with none save himself.
Orcs were mustering, and far to the east and the south the wild peoples were arming. Then in the midst of gathering fear and the rumour of war the foreboding of Elrond was proved true, and the One Ring was indeed found again, by a chance more strange than even Mithrandir had foreseen; and it was hidden from Curunir and from Sauron.
For it had been taken from Anduin long ere they sought for it, being found by one of the small fisher-folk that dwelt by the River, ere the Kings failed in Condor; and by its finder it was brought beyond search into dark hiding under the roots of the mountains. There it dwelt, until even in the year of the assault upon Dol Guldur it was found again, by a wayfarer, fleeing into the depths of the earth from the pursuit of the Orcs, and passed into a far distant country, even to the land of the Periannath, the Little People, the Halflings, who dwelt in the west of Eriador. And ere that day they had been held of small account by Elves and by Men, and neither Sauron nor any of the Wise save Mithrandir had in all their counsels given thought to them.
