In the context of the movies, I believe what Jackson was going for is that Arwen sacrificed her immortality for
Arwen isn't necessarily dying because of the Ring, but now that she is mortal, she is dying through the slow decaying of time. Arwen also faces the same fate as all those in Middle Earth should the Ring Bearer fail his mission. So in that way, her fate is tied to the Ring.
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.
Once an elf engages in reciprocated love with someone, that's it. If he cannot be with that person he will lose the will to live, die, and become a forever-shade in the Halls of Mandos. Elves do not move on.
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.
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.
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.
Puberty and full height are attained at around their fiftieth to one hundredth year, when they stop aging physically.
One year after Aragorn's death, Arwen dies at the age of 2,901.
Arwen chooses to be a mortal like her uncle Elros. So yes, she will die eventually. But as she is descended from half elven people, her life may yet be much longer than Aragorn's which will suck according to Elrond.
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.
Her constitution already severely weakened by loneliness and despair, combined with physical injuries, Éowyn then succumbed to the Black Breath. Théoden, not knowing that she was nearby, told Merry with his dying words that she had been "dearer than daughter" to him.
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.
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.
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".
Never. That was the point. She was smitten with him and he refused as he was pledged to another. Unlike many other medieval stories, he never cheated, and she had to finally realize that he was never going to give in and she had to find one who was her equal and willing in Faramir.
Legolas Was 2,931 Years Old (in the Films)
Tolkien actually never specified an age for the bow-toting Silvan Elf.
Gandalf's age is impossible to determine, but he's likely existed for at least 10,000 years, making him much older than Legolas.
All those who are familiar with old editions of The Lord of the Rings know that originally Aragorn lived to the age of 190 years. Arvegil, the king mentioned in the line in question, did live to be 190 years old so the line in question was correct in the original text.
That said, the people behind the “official movie guide” for The Lord of the Rings list Legolas as being born in the year 87 of the Third Age of Middle-earth, which makes him some 2,931 years old around the time of the War of the Ring, which happened over 3,000 years into the Third Age of Middle-earth.
An elf typically claims adulthood and an adult name around the age of 100 and can live to be 750 years old. What this says to me is that if you want an elf that looks like a 20 year old human and acts like a 20 year old human, you play a 20 year old elf.
He is thought to be over 10,000 years old by the time the War of the Ring takes place, and in all those many long years, he is credited with saving the entire elven race, selflessly putting his own wants and desires aside for the good of all, and of being a vessel through which the divine could communicate with the ...
Arwen was her granddaughter
Galadriel and Celeborn had a daughter named Celebrian, who married Elrond and became the mother of Arwen (as well as her brothers, Elladan and Elrohir).
Because Arwen has forfeiten her elven privilege to board the ships to the west a long time ago. When Arwen died, she died as a human foregoing her Elven self.
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.
