The "Three Rings of Power" are significant artifacts in J.R.R. Tolkien's legendarium, specifically within the context of Middle-earth. Crafted by the Elven smiths of Eregion, these rings were designed to enhance the abilities of their bearers and to preserve the beauty of the world. They are known as Narya, Nenya, and Vilya, each associated with different powers and responsibilities. Unlike the other rings, the Three were not tainted by the influence of Sauron, who forged the One Ring to control all others. The rings were held by key characters: Gandalf possessed Narya, Galadriel held Nenya, and Elrond wore Vilya, each using their ring to protect and nurture their realms.
