Yes, Elrond eventually realized Halbrand was Sauron in The Rings of Power after finding a genealogy scroll proving Halbrand wasn't the true King of the Southlands, though he pieced it together just as the Elven Rings were being made, learning the full extent of the deception from Galadriel. He understood Halbrand was a deceiver, but the actual name "Sauron" and the terrifying scope of his return dawned on him (and others) as he witnessed the completion of the rings.
They specifically chose to not have her tell anyone, Elrond knows by the discovery of the scroll that Halbrand was not as he seems, but he has no reason to jump from that to "He's totally Sauron". Remember, only Galadriel thought he still existed.
Isildur took up the hilt-shard of Narsil, Elendil's sword, and cut the One Ring from the hand of Sauron. Despite the urging of Elrond and Círdan, Gil-galad's lieutenants, Isildur did not throw the Ring into the fires of Mount Doom.
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.
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.
The movie the Battle of Five Armies expanded on Tolkien's canon by saying that the white gems Thranduil wanted back from the dwarves were originally intended for her, but that she was captured and taken and tortured to death by Gundabad orcs before the order was completed.
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.
As a Maia, Gandalf was an angelic being in human form, in service to the Creator (Eru Ilúvatar) and the Creator's 'Secret Fire'. He took on the specific form of an old man as a sign of his humility. His role was to advise but never to attempt to match Sauron's strength.
Sauron needed Gandalf out of the picture permanently, as he was the only enemy with the knowledge, leadership and determination to thwart him. His biggest mistake was ego. He succeeded by trickery, by his ability to deceive others. He conquered so much land that his ability to control became out of reach .
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.
Why does Gandalf say he is Saruman when he comes back as 'Gandalf The White'? It was just a figure of speech, one might almost say; he was Saruman in the sense that he is now the head of the order or that he would be the good Saruman.
He did not trust Gollum, for he divined something indomitable in him, which could not be overcome, even by the Shadow of Fear, except by destroying him.
He was briefly considered to be a member of the Fellowship of the Ring, but was later ruled out: his power would be of no use in a mission of secrecy to Mordor.
For example, the Necromancer is never seen in the novel, but in The Hobbit: An Unexpected Journey film, the Wizard Radagast the Brown enters the fortress Dol Guldur and sees the Necromancer.
It was a secret that Gandalf was the bearer of that ring. Only Círdan knew he had it because he gave it to him when he sailed over as the last Istari. Seamus Tate Saruman knew that Gandalf had it; Tolkien notes that it was one of the things that first made Saruman envious of Gandalf.
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.
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.)
Instead, we have to consider that Sauron, the original owner, is not human, but has a quasi-divine status. Therefore ownership of the Ring is subject to Divine Law. With this precedent in mind, many of the ambiguities clear up nicely. After numerous transfers by violence and trickery, Frodo is the true owner.
'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.
Answer and Explanation:
There are three Elven rings of power, and they are worn by Elrond, Galadriel, and Cirdan. All three are powerful rulers in the Elven Kingdom. Thranduil, as the King of the Woodland Realm, is not considered important enough to possess a ring.
He attacks the Orcs in rage, and is later confronted by Bolg. He saves Tauriel from being attacked by Bolg, but is mortally wounded during the fight. Kíli dies with Tauriel by his side. Bolg is eventually killed by Legolas while Azog is killed by Thorin himself avenging the brothers.
She was captured and tormented, receiving a poisoned wound. Her sons rescued her and she was physically healed by Elrond, but never fully recovered in mind or spirit, and no longer wished to stay in Middle-earth. She left for the Grey Havens and passed over the Great Sea the following year.
