"The Mirror of Galadriel was a silver basin of water used in the Elven realm of Lothlórien by Galadriel. The Mirror was used to grant the viewer things of the past, present, and possible future. It could show images that the viewer desired to see, or that of its own choice."
The more I learn about this fucked up world, the more I understand the symbolism in the books by JRR Tolkien and GRR Martin.
If I remember correctly from The Book of Enoch (might be wrong), Galadriel was the original name of the being forever after called Satan (a title that means The Enemy)
