the Evenstar, a jewel which Arwen gives to her love
Princess Arwen Evenstar gave her beautiful necklace to Aragon to pledge her eternal love to him. This special gift from an immortal elf to a mortal man symbolized Arwen's decision to forsake her immortality to be with the person she truly loves.
Arwen's pendant, the Evanstar is not a source of immortality, though a casual viewing of the films without the books to back them up can lead to one mistakenly thinking it was a source of power for her.
The Evenstar necklace symbolized love. Arwen gave it to Aragorn as a reminder of how much she loves him. It shows that nothing, not even her own immortality, is more important than her love for him. The necklace can also be seen as a symbol of hope.
Arwen wore the Evenstar at the beginning of The Fellowship of the Ring, but gave it to Aragorn before he departed with the Fellowship. Although Elrond didn't exactly approve, they were lovers, so when Arwen gave Aragorn her Elvish necklace, it represented her commitment and never-ending love.
Because Arwen is Elrond's daughter and also Half-Elf, she too has the choice to be a mortal woman or an immortal Elf. In Arwen's mind, there is nothing that can separate her from Aragorn, as she would rather die happy with him than regret her decision to leave him for all of eternity.
Evenstar is an old term for the "evening star" of astronomy, denoting the planet Venus or (less commonly) the planet Mercury.
She has a vision of a child clothed in white running across her path. She watches as the boy runs with his arms outstretched to his father, an aged Aragorn, who picks him up with joy and kisses him. As the boy looks at her and she sees he is wearing the Evenstar, she knows the boy to be her child.
At this point Arwen has already given up her immortality, but now she grants the grace of the Eldar to Frodo, not giving him immortality since he is not one of the elves, but instead granting him a home in the undying lands when he does pass.
No, their children and other descendants will be mortal. Arwen gave up her immortality to marry Aragorn and thus could not pass it on.
Elrond has only Half-Elf, and he was once given the choice to be counted among Man or Elves. When he chose to be counted as Elven kind, he was then given immortality. Because Arwen is Elrond's daughter and also Half-Elf, she too has the choice to be a mortal woman or an immortal Elf.
According to 'The Tale of Aragorn and Arwen', from Appendix A of LotR, Aragorn II (Elessar) and Arwen had at least three children: one son, Eldarion, who succeeded his father as king, and at least two daughters, as there is a mention of unnamed 'daughters'.
However, he does not possess the ability to live forever, and he cannot choose to be mortal or immortal like Arwen, the half-Elf he loves and eventually claims as his wife. Because Aragorn is mortal and Arwen chose to remain in Gondor and become mortal, their son, Eldarion, is mortal as well, despite his Elven lineage.
In the year 121 of the Fourth Age, after Aragorn's death, Arwen died of a broken heart at Cerin Amroth in Lórien, and was buried there one year after the death of Aragorn, to whom she had been wedded for 122 years. She was 2901 years old.
When she refuses to go to the Grey Lands and returns back to Rivendell, she begins to die almost instantly. Elrond tells Aragorn her fate is now tied to the ring.
Arwen (voiceover): "The light of the Evenstar does not wax and wane. It is mine to give to whom I will. Like my heart. Go to sleep."
And after their marriage, both Aragorn and Arwen are mortal. Arwen, therefore, could not set foot in the Undying Lands without special permission. And she wouldn't be likely to go after it in the end. So unfortunately, she would not go there, unlike Legolas, after Aragorn's passing.
Arwen didn't want Aragorn to die, because if he died so would she. She said she wasn't tired of living yet. But instead, Aragorn chose to die and Arwen lived a year longer before dying herself.
Originally, Tolkien intended for Éowyn to marry Aragorn. Later, however, he decided against it because Aragorn was "too old and lordly and grim". He considered making Éowyn the twin sister of Éomund, and having her die "to avenge or save Théoden".
She appears in the novel The Lord of the Rings. Arwen is one of the half-elven who lived during the Third Age; her father was Elrond half-elven, lord of the Elvish sanctuary of Rivendell, while her mother was the Elf Celebrian, daughter of the Elf-queen Galadriel, ruler of Lothlórien.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
In the same text, Tolkien wrote that Eldarion had lived until the age of 125, most likely having passed away in Fo.
She was captured and tormented, receiving a poisoned wound. Her sons rescued her and she was physically healed by Elrond, but never fully recovered in mind or spirit, and no longer wished to stay in Middle-earth. She left for the Grey Havens and passed over the Great Sea the following year.
The answer lies in Elros, Eärendil's son, and Aragorn's distant ancestor. Elros is also Elrond's brother, which shows Arwen's much more direct connection to Aragorn's ancestry. Elros is also the first King of the Dúnedain, a great and ancient line of Men.
No. In the movie it only breaks in his dreams. You can see it around Aragorn's neck as they approach the black gate. Not the scene immediately after he drops the Seeing Stone when he's riding, but the next one where they arrive at the black gate.
