The Fellowship of the Ring
"You speak for me also. The Wise may have good reason to believe that the halfling's trove is indeed the Great Ring of long debate, unlikely though that may seem to those who know less. But may we not hear the proofs? And I would ask this also. What of Saruman? He is learned in the lore of the Rings, yet he is not among us. What is his counsel--of he knows the things that we have heard?"
"I know little of Iarwain save the name, but Glorfindel, I think, is right. Power to defy our Enemy is not in him, unless such power is in the earth itself. And yet we see that Sauron can torture and destroy the very hills. What power still remains lies with us, here in Imladris, or with Cirdan at the Havens, or in Lorien. But have they the strength, have we here the strength to withstand the Enemy, the coming of Sauron at the last, when all else is overthrown?"
"And that we shall not find on the roads to the Sea. If the return to Iarwain be thought too dangerous, then flight to the Sea is now fraught with gravest peril. My heart tells me that Sauron will expect us to take the western way, when he learns what has befallen. He soon will. The Nine have been unhorsed indeed but that is but a respite, ere they find new steeds and swifter. Only the waning might of Gondor stands between him and a march in power along the coasts into the North; and if he comes, assailingthe White Towers and the Havens, hereafter the Elves may have no escape from the lengthening shadows of Middle-earth."
"And yet its vigilance can no longer keep back the Nine. And other roads he may find that Gondor does not guard."
