Arwen was a character in J.R.R. Tolkien's Middle-earth legendarium, and she played a significant role in the Lord of the Rings trilogy.

According to Tolkien's mythology, Arwen was the daughter of Elrond, the half-elven lord of Rivendell, and Celebrían, the daughter of Galadriel and Celeborn. Arwen's brothers were Elladan and Elrohir. She was also a distant relative of Lúthien, one of the greatest figures in Elven history.

As a Half-elven, Arwen chose between mortal life and eternal life as an immortal elf. She chose to become mortal and marry Aragorn, the human king of Gondor. Their love was a central theme in the Lord of the Rings trilogy and was based on the deep and enduring love shared by Lúthien and Beren, two characters from earlier in Tolkien's mythology.

Arwen gives Aragorn the Evenstar pendant as a token of her love and commitment to him

Arwen played a small but essential role in the Lord of the Rings trilogy. She met Aragorn while he was travelling in Rivendell, and they fell in love. She later helped Frodo and the other hobbits escape from the Nazgul by summoning a flood to sweep them away.

Arwen gives Aragorn the Evenstar pendant as a token of her love and commitment to him. This occurs after Aragorn has proven himself as a brave and capable leader and after the two have become betrothed. The Evenstar pendant is a beautiful and valuable piece of jewellery that Arwen inherited from her mother. Aragorn wears the pendant as a symbol of his love for Arwen and a reminder of her and their shared future together.

Despite her love for Aragorn, Arwen was torn between her duty to her people and her desire to be with him. In the end, she chose to be with him and became mortal. Arwen and Aragorn were married, and they had a son, Eldarion.

Arwen is an elf, Aragorn is a human, and Aragorn is a distant relative and eventual heir to the throne of Gondor. The two characters fall in love and become betrothed, but their relationship is tested by the challenges and dangers they face. Despite her love for Aragorn, Arwen was torn between her duty to her people and her desire to be with him. In the end, she chooses to be with him and becomes mortal. Their love for each other remained strong, and they were eventually married in a ceremony attended by friends and family from both the human and elven worlds.

Arwen lived a long and happy life with Aragorn and eventually passed away, leaving behind a legacy as one of the most significant figures in Middle-earth history.

After his parents' death, Eldarion becomes the King of Gondor and Arnor, ruling over the reunited kingdoms for many years.
