Gandalf and Sauron are both Maiar.
As soon as the Mystics realize the Stranger isn't Sauron, they label him an "Istar." With this label, and several other hints throughout the episode and the season, The Rings of Power has all but confirmed that the Stranger is everyone's favorite wizard: Gandalf the Grey.
Gandalf was one of the Maiar, a race of beings who assisted in the original creation of Arda (the location of Middle-Earth) and he was incredibly powerful. Originally Gandalf served as a divine emissary for the gods of creation, the Valar, and was tasked with defeating Sauron.
In early editions of The Guide to Middle Earth, Sauron is described as "probably of the Eldar elves".
Galadriel was the greatest and most powerful of all Elves in Middle Earth in the Third Age. Sauron the deceiver gave three Elves Rings of Power because he knew how strong they were, and he wanted to control them and have them on his side. Galadriel surpassed all other Elves in beauty, knowledge, and power.
Would Sauron be able to taint and subsequently command Elrond, Galadriel and Gandalf through the use of their own elven rings, like he does with the Ringwraiths? In theory, yes.
Historyedit. Balrogs, also called Valaraukar, were originally Ainur created by Ilúvatar, probably those who joined Melkor during his discordance in the Music of the Ainur. After entering into Eä, they were Maiar, lesser spirits at the service of the Valar.
To win the elves over, Sauron goes to Eregion disguised as Annatar, the Lord of Gifts. He helps Celebrimbor and the other smiths gain an even higher mastery of their crafts, but he leaves once they begin crafting the Rings of Power. The Three Rings of the elves are made last.
Gandalf was scared of this beast because he knew how powerful it was since it was a Maia like himself, but it was purely evil.
Nevertheless, Tolkien left clues that Bombadil is a Vala, a god of Middle-Earth, specifically Aulë, the archangelic demigod who created the dwarves. Robert Foster suggested in 1978 that Bombadil is one of the Maiar, angelic beings sent from Valinor.
Legolas was a nice little Elf princeling yet he was nothing next to the Elven king Gil-Galad. So no, Aragorn and Legolas could not defeat Sauron in hand-to-hand combat.
The Elves' fading is said to be a consequence of the darkness Morgoth brought to the realm. The Rings of Power borrows the basic elements of Elves fading away and Valinor offering the path to salvation, but embellishes the rest.
It begins after Sauron's master, the evil lord Morgoth, is defeated. Sauron may have gone into hiding, but he's still alive: the series will eventually show Sauron's creation of the titular rings of power—including the one ring to rule them all.
Legolas is a Sindarin Elf from the Woodland Realm of Northern Mirkwood. His father, Thranduil, is the King of the Silvan Elves living in that realm, making Legolas the Prince of Mirkwood.
Sauron was the most powerful of the Maiar—primordial spirits created to help the Valar first shape the World. His original name was Mairon, which means "the Admirable," and as an immortal spirit born before the world's creation, he was able to perceive the Creator Eru Ilúvatar directly.
Especially in Tolkien's The Lord of the Rings, orcs appear as a brutish, aggressive, ugly, and malevolent race of monsters, contrasting with the benevolent Elves. They are a corrupted race of elves, either bred that way by Morgoth, or turned savage in that manner, according to the Silmarillion.
Legolas was portrayed by Orlando Bloom. In the "official movie guide" for The Lord of the Rings, a birthdate for Legolas is set to 87 of the Third Age. This would make him 2931 years old at the time of the War of the Ring. This date for Legolas' birth was made up by the movie writers.
The movies only make them look alike because they're creatures not because they're twins. Dobby is a house-elf and Gollum is a misshaped human. Dobby's cute, Gollum's not, Dobby actually helps his lot.
Is a harfoot a hobbit? Sort of. Harfoots are ancestors to the hobbits you know from the films, like Frodo, Samwise, Merry and Pippin. There are in fact three ancestral breeds of hobbits: harfoots, stoors, and falllohides.
