Fans know from the later Lord of the Rings and The Hobbit tales, that Galadriel eventually finds, falls in love with, and marries Celeborn, the elf who accompanies her down the stairs when the fellowship first arrives in Lothlorien.
Sauron did desire Galadriel... He desired to make her his puppet-Queen. He didn't have any romantic feeling for her. He didn't want to marry her or have romance with her.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
Tauriel truly threw a wrench in Legolas' life when he fell in love with her. She was brave, fierce, and a protective leader of the guard. He was meant to be the dutiful son of King Thranduil, but in loving her, he became a stubborn, masterful archer instead. He loved exploration and adventure over his duties.
Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him. Thranduil, in fact, makes it clear that he does not consider her to be a suitable match for his son and warns her not to give Legolas false hope.
In his notes, Tolkien remarks that Sauron saw Galadriel as his equal. Add that to the fact that she's untrusting of Sauron (yes, even when he's in his Annatar guise) and an unwavering, single-minded force, and it's more likely than not that Sauron feared Galadriel — or the potential she held to upend his plans.
Sauron seemed to genuinely feel a connection to her, and part of that came from sensing the darkness inside of Galadriel. In that regard, his offer was really a seduction to the dark side.
Through her great-grandmother, Idril, Arwen was a descendant of King Turgon of the Noldor. Through her mother, she was the granddaughter of the Elf-queen Galadriel of Lothlórien. Through both of her parents, Arwen was a direct descendant of the ancient Elven House of Finwë.
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.
The majority of her powers come from her Ring of Power, Nenya, the Ring of Water. The ring, also known by the names the White Ring and the Ring of Adamant, is one of the three Rings of Power given to the Elves of Middle-earth in the Second Age.
Although this relationship may have happened with Galadriel's meeting or not, it's clear Gimli's love for her expedited his ease in befriending Legolas.
As previously stated, Gandalf is a Maia and is therefore superior to Elves regarding power. Still, this isn't to say that an elf couldn't develop enough skill and power to defeat a Maia. As a bearer of one of the Three Elven Rings (Nenya), Galadriel would have an edge against Maiar like Saruman and Radagast.
For most of his manifestation as a wizard, Gandalf's cloak is grey, hence the names Gandalf the Grey and Greyhame, from Old English hame, "cover, skin". Mithrandir is a name in Sindarin meaning "the Grey Pilgrim" or "the Grey Wanderer".
She tells Gil-galad that, "Evil does not sleep; it waits." In The Rings of Power, Galadriel's conviction came across as arrogance and anger. In Lord of the Rings, Galadriel was not shown as a warrior, which makes the comparison with the character depicted in The Rings of Power jarring and difficult to reconcile.
Bloodlines are very important in Tolkien's stories, and it makes a lot of sense that Sauron would fear the great-grandson of the man who cut off his hand. Aragorn carried the blood of Numenor with him. His genetic connection to the heroes of the Second Age established him as a dangerous opponent of Sauron.
For those that haven't read Tolkien's work, it's easy to see why many audiences suspect Gandalf and Galadriel are in love. After all, many of their interactions in The Hobbit trilogy practically scream romance. However, their relationship remains purely platonic in Tolkien's source material.
It is possible that Legolas was related to some of the Elves of Lothlorien, but not to Galadriel. All elves are related they all come the same little lake called Cuivienen.
The Third Age. At the beginning of the Third Age, Elrond married Celebrían, daughter of Galadriel. They had three children: twin sons, Elladan and Elrohir, and a daughter, Arwen.
However, a specific scene in The Lord of the Rings has led fans to theorize that Frodo and Legolas didn't talk, not because of time, but because the hobbit didn't know Legolas' name (and was too embarrassed to ask).
Aragorn and Legolas are long-time companions and best friends since Legolas' father Thranduil sent him to live among the Rangers of the North. Aragorn and Legolas grew close, up to the point where Aragorn revealed his true identity to Legolas. Throughout his journeys, Aragorn and Legolas are as close as brothers.
