Galadriel is tempted by the thought of the power of the ring but she knows she would be risking her soul in many ways. We see a glimmer of the darkness that would taint her otherwise power of light. She says “In place of a dark lord, you would have a queen! Not dark, but beautiful and terrible as the dawn!
Galadriel and Elrond were not part of that struggle. Another reason is that they both knew that their time was coming to an end. They had lived for centuries, far longer than any other mortal beings, and their powers were waning. They could no longer have fought a war even if they had wanted to.
Frodo even offers her the one ring. Galadriel admits she has long awaited the chance to seize the powerful token. But, she says, if she took it, she would become corrupted herself and rule over Middle-earth as a beautiful but tyrannical queen.
Another aspect that the series explores is the decision to forge three rings. As Galadriel, Celebrimbor, and Elrond (Robert Aramayo) discuss after the process has already started, it is a way of preventing the concentration of power in a single being's hands. "One will always corrupt.
It is implied that if Galadriel were to wield the One Ring, she would be as powerful as Sauron himself—but with her wisdom, Galadriel recognizes the danger in such power, and she is able to resist the temptation.
Portrayal of Galadriel in The Rings of Power is divisive among the fandom. Her character is criticized for many different reasons, from her self-righteousness and abrasive personality, to her inability to detect the very evil she is hunting right under her nose.
Sauron feared her
Among Tolkien's commentaries and notes, however, is the statement that Sauron himself saw her as his equal, and was consequently worried about what she might (and could) do if she so chose.
She already feels an outcast after Gil-galad tried to send her back to the Undying Lands, and she fears that if she reveals what she has done, it will be the final nail in the coffin. Instead, when Elrond pulls her from the river Glanduin, and she races back inside to Celebrimbor's forge, she chooses to stay silent.
Sauron intended it to be the most powerful of all Rings, able to rule and control those who wore the others. Since the other Rings were powerful on their own, Sauron was obliged to place much of his own power into the One to achieve his purpose. Creating the Ring simultaneously strengthened and weakened Sauron.
Sauron is immortal and elusive, and even without the Ring he can breed armies of orcs and fortify places like Mordor and Dol Guldur. Galadriel most likely couldn't fight her way to Barad-Dur, and even if she did and destroyed Sauron in his physical form he would eventually create a new one.
Sauron wants Galadriel to become his queen because she's useful, says Vickers. As he's already shown, Sauron can accomplish his objectives much more quickly when he has a highly regarded Elf warrior to get him into places like Numenor and Eregion (where Celebrimbor lives).
Galadriel realized the truth too late, and was foolish enough to confront Sauron directly. He used his dark magic to enter her mind, using visions and hallucinations to tempt her to his side.
Elrond Didn't Have the Strength to Stop Isildur
He knew that the Ring needed to be destroyed, but actually doing it would have been different. A passage in Unfinished Tales says that Gil-galad, Círdan and Galadriel "failed to find the strength" to destroy their uncorrupted Rings of Power.
Thus, Galadriel's dark form in Jackson's The Lord of the Rings personified what would have occurred had the Lady of Lothlorien given in to temptation and taken the One Ring for herself. She would have succumbed to evil because the Ring was indomitable, even with her power.
While Sauron's One Ring is built around domination, the elven rings are built around preservation. As Elrond says at the council in Rivendell, "those who made them did not desire strength or domination or hoarded wealth, but understanding, making, and healing, to preserve all things unstained.
After Morgoth's defeat at the end of the First Age, elves like Galadriel were pardoned and offered a return to the land they abandoned. Galadriel refused, partly because she believed her people had no reason to need pardoning, but more because she always wanted to witness Middle-earth and rule a kingdom there.
The first is that Bilbo is a hobbit, and as such, is particularly difficult to manipulate or corrupt. Hobbits have a natural resistance to the influence of the ring, because they are fully content in their simple lives and have no desires for power or war.
In the spiritual world, beings are invisible to those in the physical world. This is why Isildur, Bilbo, and Frodo become invisible when they wear the Ring—because they are no longer in the physical world. As Olsen said, Sauron does not have a real body, so he is not affected in the same way.
Sauron's goal was to use the One Ring to influence and control the minds of those who wielded the lesser rings. It also possessed all the same powers as the other rings, but to a greater degree. Whoever possessed the ring could also read the minds of other ring-bearers, as well as turn invisible.
Elrond discovered the scroll that revealed that Halbrand couldn't be King of the Southlanders, so it's likely that he realized that Halbrand was Sauron and that he escaped. Knowing that Sauron is on the loose, he could warn the dwarves of the growing evil and encourage them to forge their own rings.
Though neither is someone you'd wish to annoy, Galadriel is generally considered more powerful than Elrond in Lord of the Rings. Not only is she older than her Rivendell counterpart, but Galadriel witnessed the light from Valinor's Two Trees, giving her a mystic quality.
Tolkien suggested that Sauron did not discover where the Three were hidden, though he guessed that they were given to Gil-galad and Galadriel. In the published The Lord of the Rings, Gil-galad received only Vilya, while Círdan was the direct recipient of Narya from Celebrimbor.
Aragorn was an immensely threatening figure regardless of his ancestry. He's one of the greatest warriors in all of Middle-earth, he was trained in Elvish ways by Elrond, and he held a banner all men would flock to. Sauron believed that Aragorn was the only man who could wield the Ring against him and win the war.
Her brash, bloodthirsty need for revenge against the Dark Lord Sauron has been steeped in her desire to avenge the brutal death of her brother Finrod (Will Fletcher), and while that's completely understandable for any fantasy character, Galadriel has a long and complex history that many fans feel is being ignored.
Sauron was first afraid of the idea of Aragorn, as a pretender come to claim his ring. Then after their contest for the control of the Orthanc Palantir, Sauron was genuinely afraid of Aragorn, the man. Even though he was 'just' a man Aragorn was the focal point of all things that opposed Sauron.
