The Mirror of Galadriel is a mystical basin found in the realm of Lothlórien, a forest inhabited by the Elves in J.R.R. Tolkien's *The Lord of the Rings*. It is a reflective pool that allows those who gaze into it to see visions of the past, present, and possible futures. The mirror is a gift from Galadriel, the Lady of Lothlórien, who uses it to guide and warn those who seek her counsel. When characters like Frodo and Sam look into the mirror, they witness significant events and potential outcomes related to their quest against the dark lord Sauron. The visions can be both enlightening and troubling, revealing the weight of their journey and the choices they must make. The mirror symbolizes the power of foresight and the burden of knowledge in the fight against evil.
