Arwen’s necklace, known as the Evenstar, has a special significance in the Tolkien universe. It was once gifted to Arwen by her father, the elf lord Elrond, as a symbol of his love and affection for her. While the necklace has powerful enchantments and is said to glow with the light of the Evenstar, it does not have the power to keep Arwen immortal.
Arwen’s immortality comes from her elven heritage. She is a Half-Elf, born to an elven father and a mortal mother. According to the lore, Half-Elves have the ability to choose between mortality and immortality. If they choose to stay immortal, they must leave Middle-earth and sail to the Undying Lands, where they will live forever.
Arwen initially chooses to remain immortal for the love of Aragorn, a mortal man she had fallen in love with. However, after many years of waiting for Aragorn and watching the world around her change, Arwen ultimately decides to choose mortality and give up her immortality. The decision is a difficult one, and it means that she will only have a limited lifespan, but she chooses to be with Aragorn and live out her days as a human.
While the Evenstar necklace is an important symbol of Arwen’s love and her elven heritage, it is not the source of her immortality. Rather, it is her elven blood that gives her the power of immortality, and her own choice to give it up that ultimately leads to her death.
Why did Aragorn not take the army of the dead to Mordor?
Aragorn did not take the army of the dead to Mordor for a few reasons. Firstly, it was not a feasible solution for the long term. The army of the dead was cursed to remain in a spirit form until they fulfilled their oath to fight for Gondor. Once that oath was fulfilled by aiding in the Battle of Pelennor Fields, they were released from their curse and could finally pass on to the afterlife. It was not within Aragorn’s power to keep them bound to his will, nor would it be ethical to do so.
Secondly, the army of the dead was not invincible. Yes, they could not be killed by mortal weapons, but they could be immobilized or captured by other means. Their spiritual form also meant that they could not interact with the physical world as effectively as a flesh and blood army, which would be necessary to fight the armies of orcs and other creatures that Sauron commanded.
Finally, taking the army of the dead to Mordor would have been a hollow victory. The goal was not simply to defeat Sauron, but to do so in a way that preserved the humanity and free will of Middle Earth. By using the army of the dead, Aragorn would have been perpetuating a cycle of violence and subjugation rather than achieving a truly meaningful and lasting victory.
Aragorn recognized that defeating Sauron required a multifaceted approach that included diplomacy, intelligence gathering, and strategic alliances. By marshaling the forces of Gondor, Rohan, and other allies, he was able to achieve a victory that was not only powerful but also sustainable.
