After the One Ring was destroyed, Galadriel, having passed her ultimate test by refusing it, eventually sailed West from the Grey Havens to the Undying Lands (Valinor) with other great Elves like Elrond, as the power of the Three Elven Rings faded, marking the end of the Elves' time in Middle-earth. She chose to leave Middle-earth to find healing and peace in Valinor, a privilege earned after centuries of resisting the Ring's temptation and fulfilling her purpose in Middle-earth.
Galadriel turns "dark" and scary to show what she would become if she claimed the One Ring, a symbolic and not literal transformation.
It's possible that Gollum's prolonged search for the ring allowed it to maintain a significant power over him, suspending his aging process. In contrast, Bilbo's exposure to the ring's influence waned after he willingly (mostly) relinquished it, allowing his aging to resume more noticeably.
Frodo sails to the Undying Lands because the Ring's wounds--physical, psychological, and spiritual--left him unable to find full healing in Middle-earth. The voyage is a merciful, honored cure offered by the Valar and Elves, fitting both the character's sacrifices and the mythic structure of Tolkien's world.
But that's actually the answer: Eru Said So . The Undying Lands are a place for immortal beings (Eldar), and mortals are forbidden from entering.
They get to choose between a truly mortal life, or an elven life (including their afterlives since Men don't get resurrected in Valinor), so when she chose a mortal life to stay in Middle Earth , she permanently chose the destiny of Men as well.
Just comparing Galadriel to Elrond in The Lord of the Rings and The Hobbit films, Galadriel is portrayed as much more powerful in terms of magical abilities.
Tolkien's description of Gollum conforms to a Catholic – and Thomistic – account of envy, which is a “sadness of the soul”; and it is Gollum's unbearable sadness and his unquenchable desire for the one Ring that marks his character.
It's not the years; it's the mileage. Gandalf isn't a Maia in the same way Sauron is. He was sent to middle earth as an old man, so his body is much more real than Sauron's “raiment”. He can't use his power to the same extent, he can't change his forms at will.
Because he was a ring-bearer. It was a special honor granted to him, because he bore the one ring all the way to Mount Doom. He needed healing for his wound from the Morgul blade, and the severe psychological trauma he had from bearing the one ring, that only the undying lands could provide.
In the books Bilbo hadn't even come close to catching up with his biological age until after the Ring was destroyed. (And since Gollum was destroyed with the Ring, there wasn't any chance for his age to catch up with him.)
'The Fellowship of the Ring' (2001)
If Gandalf had stayed dead after his sacrifice in The Fellowship of the Ring, then his demise would be the saddest in the trilogy, but since he came back, the saddest single death scene of all three movies goes to Boromir's.
A group of UCL medical students, led by Dr. Liz Sampson, concludes that Gollum was actually suffering from schizoid personality disorder.
The main reason is just that The Hobbit was written first and Legolas was not conceived until LOTR was being written. There was a character named Legolas Greenleaf in the older versions of The Fall of Gondolin but that's a case of a different character having the same name as a later one.
Why was Sauron afraid of Aragorn potentially possessing the Ring? Gandalf explains it in the Return of the King (during the council after the battle of the Pelennor fields) that Sauron would never think somebody would want to destroy the One Ring.
In Valinor, Gandalf, a Maia, was named Olórin, one of the people of the Vala Manwë, and the wisest of the Maiar. He was closely associated with two other Valar: Irmo, in whose gardens he lived, and Nienna, the patron of mercy, who gave him tutelage.
Gollum is a hobbit that is featured in The Lord of The Rings, where his story his primarily focused on his possessive love of the One Ring. The power of the ring causes an unusual extension of life and in Gollum's case caused him to live to around 500 years old.
The Ent who figures most prominently in the book is Treebeard, who is called the oldest creature in Middle-earth.
The Posttraumatic Stress Disorder of Frodo Baggins
J.R.R. Tolkien in The Lord of the Rings accurately portrayed the signs and symptoms of what is currently labeled Post Traumatic Stress Disorder. Frodo's condition logically follows his experiences of less than a year in the War of the Ring.
Literature's greatest villain and by far the most well-known in The Lord of the Rings, Sauron was actually following in the footsteps of an evil that may have been greater than him.
Merry and Pippin both died decades BEFORE Aragorn died. Merry and Pippin died in FA 63, while Aragorn died in FA 120 - and it was after this that Legolas and Gimli sailed to the Undying Lands. All of this is made patently clear in Tolkien's own timelines.
To clarify: Tolkien is fairly clear that Fëanor had the greatest potential of any elf, ever.
Legolas is introduced at the Council of Elrond in Rivendell, where he came as a messenger from his father to discuss Gollum's escape from their guard.
Arwen married Aragorn in the year 3019 of the Third Age, when he was 88 years old and she was 2,778 years old. The last year of the Third Age was 3021. Aragorn ruled until the year 120 of the Fourth Age, when he was 210 years old.
