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.
Legolas was the son of Thranduil, King of the Woodland Realm of Northern Mirkwood, who appeared as "the Elvenking" in The Hobbit. Thranduil, one of the Sindar or "Grey Elves", ruled over the Silvan Elves or "Wood-elves" of Mirkwood.
The actor is suffering from Legolas Syndrome — where you accidentally get cast into a role that suits you far more than your real-life looks, leaving you with a tricky predicament after the wrap party.
Legolas was a Sinda Elf, the prince of the Woodland Realm of Mirkwood. His grandfather Oropher was of the Sindar of Doriath, and his father Thranduil was king of Mirkwood (Greenwood the Great).
This means that Thranduil had a stronger claim to kingship, and that although both Elrond and Galadriel could have claimed this title too, they both decided against it and were happy to be labeled guardians and protectors of their lands, rather than authoritarian rulers.
Arwen is one of the half-elven who lived during the Third Age; her father was Elrond half-elven, lord of the Elvish sanctuary of Rivendell, while her mother was the Elf Celebrian, daughter of the Elf-queen Galadriel, ruler of Lothlórien.
Legolas's Family Tree
Yet, since Tolkien does give family trees for other important Elves in the book, such as Galadriel and Elrond, it's clear that Galadriel is not Legolas's mother. (Besides, she is one of the Noldor, not a Silvan or Sindar Elf.)
Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in canon. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring.
In the films, Bloom wore contacts to make his eyes blue, probably to distinguish him from the Silvan elves of Mirkwood, Legolas, the son of Thranduil, is a Sindarin, often treated as nobility by elves of less distinguished lineage.
That said, the people behind the “official movie guide” for The Lord of the Rings list Legolas as being born in the year 87 of the Third Age of Middle-earth, which makes him some 2,931 years old around the time of the War of the Ring, which happened over 3,000 years into the Third Age of Middle-earth.
Legolas tells Gimli that his final count is 42 Uruks.
He Has Incredible Eye-Sight
One such power is his incredible eye-sight, something that all Elves are gifted with. In The Two Towers, Legolas is able to track the Orcs while being 20 kilometers away from them, as well as know that "The White Wizard" is coming long before Aragorn and Gimli can.
Aragorn is not half Elf, although he is a descendant of Elros, who is half Elf (and the brother of Elrond, the half-Elf who raised him), which explains why Aragorn's life span is unusually long.
He Abandoned Romance For Friendship
While he became averse to falling in love, the son of Thranduil did not become loveless. Legolas traded romance for strong, loving companionship among friends.
Legolas never marries. The closest he gets is spending the rest of his life, as far as we know, with Gimli; they travel around Middle Earth for decades together, and eventually Gimli is given special dispensation to travel to the Undying Lands with his "friend" Legolas—the only dwarf ever to do so.
However, Tauriel also has a "softer side", and her character arc includes a love story. Though she and Legolas first met as children, and their relationship is significant, her romantic arc is not with him, as she develops a mutual attraction to the dwarf Kíli.
No, Thranduil does not have a ring of power in The Hobbit. 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.
Lord of the Rings film trilogy
Luthien Thranduiliel is the second child of the King Thranduil of Mirkwood and his wife Calathiel . She is the little sister of Legolas, born in mid TA 240 in Woodland Realm of Mirkwood.
Arwen isn't necessarily dying because of the Ring, but now that she is mortal, she is dying through the slow decaying of time. Arwen also faces the same fate as all those in Middle Earth should the Ring Bearer fail his mission. So in that way, her fate is tied to the Ring.
They are both elvish nobles, as Legolas is the son of King Thranduil and Arwen is the daughter of Elrond.
