The first question:
About Arwen’s mother Celebrian.
Original records:
Arwen’s mother Celebrian was attacked by orcs at the Redhorn Gate in 2509 and suffered torture and trauma. Although she was later rescued by her sons and Elrond healed her trauma, Celebrían was still haunted by horrific memories and finally decided to leave Middle-earth the following year.
Second question:
Frodo, his cousin Bilbo, Gandalf and the elves went to Aman, which is also known as the "Land of the Immortal". "Land", "Blessed Land", "End of the West", Frodo as a mortal could not have this privilege, but his experience as a holder of the Lord of the Rings allowed him to obtain this privilege. Another theory is that Arwen, Aragon's wife, gave Frodo the right to go to Aman.
The main purpose of Frodo going there was to heal his wounds. The wounds he suffered from the sword of the Ringwraith King, the stings of Shelob the great spider, and the wounds he suffered from wearing the Lord of the Rings were all unparalleled in Middle-earth. People can be completely healed, even Lord Elrond, the best healer in Middle-earth, is unable to do anything. In the movie, Frodo mentioned that these injuries occur every year, so he must leave Middle-earth and go to "Blessed" with the elves. The land of Aman can only be cured by asking the Valar there for medical treatment.
Aman is home to 14 Valar (mighty ones, builders, perfecters and managers of the world) who are worshiped as gods by elves and humans, as well as many Maya under the Valla. The light elves also live here, which can be compared to the paradise of our world. It is located on the other side of the sea. After the sinking of Numenor, it can only be reached by taking an elven ship along the "straight channel". This is also the home of the elves. Most of the elves cannot bear the increasing decay and aging of Middle-earth, so they can only live in Aman, the "land of everlasting spring" where beautiful things can last forever. Frodo is a hobbit and does not have the right to eternal life. He cannot live forever in Aman, but there he can enjoy a long life and spend the rest of his life in peace and tranquility.
