'Suddenly the River swept round a bend, and the banks rose upon either side, and the light of Lórien was hidden. To that fair land Frodo never came again.
The travellers now turned their faces towards the journey; the sun was before them, and their eyes were dazzled, for all were filled with tears. Gimli wept openly.
'I have looked the last upon that which was fairest,' he said to Legolas his companion. 'Henceforward I will call nothing fair, unless it be her gift.' He put his hand to his breast.
'Tell me Legolas, why did I come on this Quest? Little did I know where the chief peril lay! Truly Elrond spoke, saying that we could not forsee what we might meet upon our road. Torment in the dark was the danger that I feared, and it did not hold me back. But I would not have come, had I known the danger of light and joy. Now I have taken my worst wound in this parting, even if I were to go this night straight to the Dark Lord. Alas for Gimli son of Glóin!'
'Nay!' said Legolas. 'Alas for us all! And for all that walk the world in these after-days. For such is the way of it: to find and lose, as it seems to those whose boat is on the running stream. But I count you blessed, Gimli son of Glóin: for your loss you suffer of your own free will, and you might have chosen otherwise. But you have not forsaken your companions, and the least reward that you shall have is that the memory of Lothlórien shall remain ever clear and unstained in your heart, and shall neither fade nor grow stale.'
