The three Elven Rings (Narya, Nenya, Vilya) weren't directly corrupted because Celebrimbor forged them alone, without Sauron's direct hand or presence, after learning his craft, keeping them "unsullied" from his touch, though they remained linked to the One Ring's power, hence the Elves removed them when Sauron claimed the One. Their purpose was preservation, not domination, allowing Elves to resist evil and maintain beauty, but their power faded when the One Ring was destroyed, as they drew their ultimate strength from it.
By lingering behind, she chose mortality so she could rejoin him. She died a year after him of heartbreak if I recall correctly. She chose a mortal life to be with Aragorn, as such she could no longer travel to or set foot upon Valinor. Gimli, Bilbo, Frodo, and Sam were the only mortals ever granted passage to Valinor.
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.
Aragorn resisted the Ring because of character, training, destiny, and practical judgment--each reinforcing the others rather than a single moment of self-control.
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.
Because of their contribution to destroying the One Ring, saving Middle Earth and averting Sauron's eventual war on the Valar, they are granted the privilege of seeing the Undying Lands.
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.
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.
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.
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.
Elrond chose the fate of the Elves and therefore the choice was presented to his children. The reason why Eldarion and his sisters (the children of Aragorn and Arwen) were born mortal was because Arwen chose mortality and therefore that fate was passed on to the rest of their line.
And after Aragorn's death, Legolas built a ship in Ithilien and sailed down the Anduin River, passing beyond the sea. It's said that Gimli joined him on that journey. With their departure, the tale of the Fellowship of the Ring came to an end. Some say the two had many adventures together in the Undying Lands.
"In sorrow we must go, but not in despair. Behold! we are not bound for ever to the circles of the world, and beyond them is more than memory".
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.
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.
Melkor is the most powerful of the Valar but he turns to darkness and is renamed Morgoth, the primary antagonist of Arda. All evil in the world of Middle-earth ultimately stems from him. One of the Maiar of Aulë betrays his kind and becomes Morgoth's principal lieutenant and successor, Sauron.
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.
The Ent who figures most prominently in the book is Treebeard, who is called the oldest creature in Middle-earth.
Gandalf the Grey's light up staff by noble collection (the staff used in The Hobbit, an Unexpected Journey) came in three pieces and had a plastic like finish. Due to the technical elements some design elements were markedly different to the United Cutlery and Wētā versions of the staff.
After its conclusion, many Northmen emigrated to Gondor, and that is how Gondor's blood became "mingled". (LOTR Appendix A) So yes, Aragorn's blood can be considered "purer Númenorean".
One of the things I like most and am proud of in this world is that Viggo Mortensen was offered to play Aragorn again in The Hobbit trilogy, but he declined because he said Aragorn did not appear in the book.
I would rather share one lifetime with you than face all the ages of this world alone.
