This appears to describe a real physical eye with a terrible stare. The films insist that Sauron is too weak to take a physical form, and imply that he can only serve as watchful eye over
The War of the Last Alliance lasted many years, but Sauron was defeated. J. R. R. Tolkien described the Eye of Sauron in a metaphorical sense, as it was not an actual eye but rather a symbol of Sauron's influence over Middle Earth.
Although it is unknown what he truly looked like under his armor after the fall of Númenor, it his stated that after he no longer had the ability to use his fair form, Sauron resembled a being or pure darkness, horror, and malice.
The Great Eye is the image the Dark Lord uses to brand himself and his armies, projecting an aura of omniscience. As propaganda, the Eye of Sauron is the most potent symbol in Middle-earth — and its effectiveness is built on the genuine power of Sauron's gaze, literal and otherwise.
When Sauron was defeated by Prince Isildur of Gondor, his finger was severed, as was the One Ring. He also lost his physical form and from then on manifested as The Eye of Sauron.
Sauron was initially able to shift his appearance, but when he became a servant of Morgoth, he took on a sinister form that Tolkien described in his letters as slightly bigger than human stature yet not giant. This version of Sauron had daunting eyes and appeared as malice and hatred incarnate.
Sauron did have a physical body, at least in the books. Peter Jackson chose to put the eye over Mordor to create a sense of danger and urgency. In the books he has a body by, at most, The Two Towers. "Yes, He has only four fingers on the Black Hand, but they are enough,” said Gollum, shuddering.
Unlike Isildur, Frodo ultimately decides to cast the One Ring into the fiery volcano of Mount Doom and destroy Sauron for good. With nothing to retain his lifespan, Sauron is destroyed and vanquished from Middle-earth for eternity.
In The Book of Lost Tales, it is said that Orcs were "bred from the heats and slimes of the earth" through the sorcery of Morgoth. Again, Tolkien later changed this, as Morgoth could not create life on his own. This led to the most popular theory that Orcs were created from corrupted Elves.
Sauron does survive in some form after the destruction of the Ring. However, since he put so much of his own power into the Ring, he only exists as an evil spirit and cannot do anything. Instead of having control over all the people of Middle Earth, Sauron barely has control over his own fate.
Gandalf, like all the five wizards of Middle-earth, was a Maia, an angelic spirit of the same order as Sauron.
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.
Sauron began his days as Mairon (“the admirable”), a powerful Maia—spirits who came to Arda to help the Valar shape the world. (Other Maia include Gandalf and Saruman.) He was a pure and orderly being in the beginning, who studied the craft of forging. But he grew selfish, and eventually aligned himself with Morgoth.
Sauron was originally a Maia called Mairon, but he could take on a fair visage and call himself Annatar or Halbrand. He is not an elf or human, but an extremely powerful being and the main antagonist of J.R.R. Tolkien's The Lord of the Rings.
Superhuman Strength
Sauron draws much of his power from his Maiar heritage. The Maiar also have superhuman strength, much stronger than any of the other beings born of Middle-earth. Because of this, Sauron is able to wield a large mace and take down several men in one blow.
With the angle no help, and no depth perception, Sauron would have had no way of determining distance with any precision past somewhere between ten and fifty miles. If you trace a line between where the hobbits were when they were spotted and the Dark Tower, it continues through Gondor.
Since Tolkien said that Orcs were generally just seen as soldiers, then any female Orcs could have been soldiers as well. Much in the same way that female Dwarves aren't seen in The Lord of the Rings, but it is known that they still exist, the same could be true for Orc women.
Ulmo was also the Vala connected to Elves and Men in Middle-earth, and was the one who aided them the most. The Nazgûl, as servants of Sauron, feared the power of Ulmo, and believed that some of his power might still flow through the waters of Middle-earth, hence why they avoided it as much as they could.
The first Dark Lord Melkor took hostage some Elves from Cuiviénen. He tortured them, beat them, and broke their bodies into the first deformed and twisted beings known as Orcs. Tolkien confirmed that female Orcs did exist.
Immortality: As one of the Ainur, Mairon/Sauron was functionally immortal; failing that, seemingly very long-lived having existed with and without a physical form for the better part of several thousand years, Sauron was created before the physical realm of Arda and Middle-earth was established thus his age is ...
Under his rule, the Dwarves prospered well into the Fourth Age. He was succeeded by his son, Durin VII the Last, who led the Dwarves of Erebor back to Khazad-dûm to restore it to its former glory. The Dwarves remained there until the “world grew old and the days of Durin's race ended”.
Sauron's deepest fear was that Aragorn would use the Ring against him. With its powers of domination, Aragorn could comfortably take over the entirety of Sauron's dark army. Though this would eventually corrupt Aragorn, it would allow him to destroy Sauron and take his place.
During the Third Age, the term Easterling referred to various nations and tribes of Men living in uncharted lands east of the Sea of Rhûn and Mordor, who were usually subservient to Sauron (for one of their leaders was the second greatest of the Nazgûl, Khamûl) and frequently attacked Gondor and the lands bordering ...
The usual description is something like "a dark Lord, great and terrible." It's short on specifics, save that Isildur described his hand as being black but burning like fire, and that in the Third Age he only had nine fingers.
