Arwen var Evenstar av hennes folk, det sista stora ljuset av Elves kapplöpning
Sagan om Arwen paralleller den av Lúthien, faktiskt Arwen betraktades som vacker som hennes föremon, som betraktades som den vackraste elfen i alla tider. Aragorns likhet betraktas av Aragorn, i Tale of Aragorn och Arwen 1So it was that Frodo saw her whom few mortals had yet seen; Arwen, daughter of Elrond, in whom it was said that the likeness of Lúthien had come on earth again; and she was called Undómiel, for she was the Evenstar of her people.

and his daughter Arwen Undómiel, who resembles Lúthien closely in looks and fate...

Arwen is not a 're-incarnation' of Lúthien (that in the view of this mythical history would be impossible, since Lúthien has died like a mortal and left the world of time) but a descendant very like her in looks, character, and fate.

for Lúthien was the most beautiful of all the Children of Ilúvatar.
The Silmarillion - Chapter 19: Of Beren and Luthien
Namnet Undomiel fick Arwen att reflektera hennes skönhet under tiden för avlivningen av älvorna i åldern. Arwen var en återspegling av Elvernas gamla ära i årens träd och första ålder vid en tidpunkt då den förstfödda hade börjat blekna och Människans tid hade börjat. Arwen var en del av den sjätte och sista unionen av barnen i Ilúvatar (efter Luthien & Beren, Idril & Tuor, Nimloth & Dior, Elwing & Eärendil och Mithrellas och Imrazór). För att försvara henne med Aragorn, förnyar Arwen den långa glömda alliansen mellan de två raserna av barnen. Deras förlovning representerar att facklan passerade, från den förstfödde som hade styrt mellanjorden i årtusenden till den andrafödda, vars tid var stigande. Dessutom är Arwen, ensam av de höga älvorna, kvar i Mellanöstern.
Evenstar är kvar i Middle Earth för en tid efter Människans ålder, men morgonen (Galadriel, det sista minnet av en långt bortglömd ålder) passerar för evigt över havet. Detta återspeglar igen Arvens öde som det sista lysande ljuset för den förstfödda i en värld av män."But first I will plead this excuse," said Éomer. "Had I seen her in other company, I would have said all that you could wish. But now I will put Queen Arwen Evenstar first, and I am ready to do battle on my own part with any who deny me. Shall I call for my sword?"
Then Gimli bowed low. "Nay, you are excused for my part, lord," he said. "You have chosen the Evening; but my love is given to the Morning. And my heart forebodes that soon it will pass away for ever."

1 For Aragorn had been singing a part of the Lay of Lúthien which tells of the meeting of Lúthien and Beren in the forest of Neldoreth. And behold! there Lúthien walked before his eyes in Rivendell, clad in a mantle of silver and blue, fair as the twilight in Elven-home; her dark hair strayed in a sudden wind, and her brows were bound with gems like stars.
For a moment Aragorn gazed in silence, but fearing that she would pass away and never be seen again, he called to her crying, Tinúviel, Tinúviel! even as Beren had done in the Elder Days long ago.
Then the maiden turned to him and smiled, and she said: “Who are you? And why do you call me by that name?”
And he answered: “Because I believed you to be indeed Lúthien Tinúviel, of whom I was singing. But if you are not she, then you walk in her likeness.”
“So many have said,” she answered gravely. “Yet her name is not mine. Though maybe my doom will be not unlike hers. But who are you?”
