In Dwimordene, in Lórien
Seldom have walked the feet of Men,
Few mortal eyes have seen the light
That lies there ever, long and bright.
Galadriel! Galadriel!
Clear is the water of your well;
White is the star in your white hand;
Unmarred, unstained is leaf and land
In Dwimordene, in Lórien

 When Frodo peers in, he is shown indirect signs of Gandalf, Minas Tirith, Lindon, and Sauron. All four prove to have great significance throughout the events of the novel – Sauron naturally as the chief antagonist, Gandalf when he returns as Gandalf the White, Minas Tirith as the location for the huge Battle of the Pelennor Fields, and Lindon as the location of the ship which ultimately takes both Frodo and Galadriel west to Valinor.
