The Fellowship of the Ring
They had climbed on to a narrow saddle between two higher points, and the land fell steeply away again, only a short distance ahead. Frodo threw himself down, and lay on the ground shivering. His left arm was lifeless, and his side and shoulder felt as if icy claws were laid upon them. The trees and rocks about him seemed shadowy and dim.
"We cannot go much further," said Merry to Strider. "I am afraid this has been too much for Frodo. […]
"What is the matter with my master?" asked Sam in a low voice, looking appealing at Strider. "His wound was small, and it is already closed. There's nothing to be seen but a cold white mark on his shoulder."
"Frodo has been touched by the weapons of the Enemy," said Strider, "and there is some poison or evil at work that is beyond my skill to drive out. But do not give up hope, Sam!" (1.12.41-2, 44-5)
To the east the outflung arm of the mountains marched to a sudden end, and far lands could be descried beyond them, wide and vague. To the south the Misty Mountains receded endlessly as far as sight could reach. Less than a mile away, and a little below them, for they still stood high up on the west side of the dale, there lay a mere. It was long and oval, shaped like a great spear-head thrust deep into the northern glen; but its southern end was beyond the shadows under the sunlit sky. Yet its waters were dark: a deep blue like clear evening sky seen from a lamplit room. Its face was still and unruffled. About it lay a smooth sward, shelving down on all side to its bare unbroken rim.
"There lies the Mirrormere, deep Kheled-zâram!" said Gimli sadly. "I remember that [Gandalf] said: 'May you have joy of the sight! But we cannot linger there.' Now long shall I journey ere I have joy again. It is I that must hasten away, and he that must remain." (2.7.7)
All of them, it seemed, had fared alike: each had felt that he was offered a choice between a shadow full of fear that lay ahead, and something that he greatly desired: clear before his mind it lay, and to get it he had only to turn aside from the road and leave the Quest and the war against Sauron to others [...]
"Well, have a care!" said Boromir. "I do not feel too sure of this Elvish lady and her purposes."
"Speak no evil of the Lady Galadriel!" said Aragorn sternly. "You know not what you say. There is in her and in this land no evil, unless a man bring it hither himself. Then let him beware!" (2.7.40, 45-6)
