Thranduil wasn't given an Elven Ring of Power because the Noldorin Elves who forged them considered him of insufficient stature, lacking the pedigree and connection to their high-elf society, and his secluded, isolationist Sindarin/Silvan realm wasn't seen as central to Middle-earth's greater struggles, unlike realms of Elrond, Galadriel, or Círdan, though his cautious nature and focus on his own people also made him a less likely candidate for a powerful artifact.
Thranduil does not have a ring of power. If he had, Tolkien would have described the elves as having more. Concerning Gandalf and his research of the rings, he would have named anyone that had one to the reader.
They rejected it because even if he could momentarily contain the Ring, he would not be trusted to bear it into Mordor or to understand the strategic necessity of destroying it. He would not keep it secret nor use it in ways that advance the mission.
After the battle and Thorin's death, Thranduil took Orcrist, which was previously confiscated in Mirkwood, and laid it upon Thorin's tomb. The treasure was divided among Elves and Men, and Thranduil received the emeralds of Girion.
Thranduil's earliest appearances are during the War of the Last Alliance. He can be found during the Battle of Dagorlad and later is seen during the Siege of Barad-dûr. In the present time, Thranduil is first encountered fighting in Mirkwood during the last days of the War of the Ring.
The movie the Battle of Five Armies expanded on Tolkien's canon by saying that the white gems Thranduil wanted back from the dwarves were originally intended for her, but that she was captured and taken and tortured to death by Gundabad orcs before the order was completed.
Tolkien's description of Gollum conforms to a Catholic – and Thomistic – account of envy, which is a “sadness of the soul”; and it is Gollum's unbearable sadness and his unquenchable desire for the one Ring that marks his character.
He attacks the Orcs in rage, and is later confronted by Bolg. He saves Tauriel from being attacked by Bolg, but is mortally wounded during the fight. Kíli dies with Tauriel by his side. Bolg is eventually killed by Legolas while Azog is killed by Thorin himself avenging the brothers.
Gil-Galad and Thranduil would be around the same age since they both were born during the First Age. Behind them would be Elrond who was born near the end of the First Age.
He heard all about Thranduil from his dad and his buddies. Technically Legolas is a prince. so saying legolas son of Thranduil would let everyone know he is the elven prince. Which he didn't want to freely admit.
By lingering behind, she chose mortality so she could rejoin him. She died a year after him of heartbreak if I recall correctly. She chose a mortal life to be with Aragorn, as such she could no longer travel to or set foot upon Valinor. Gimli, Bilbo, Frodo, and Sam were the only mortals ever granted passage to Valinor.
Why was Sauron afraid of Aragorn potentially possessing the Ring? Gandalf explains it in the Return of the King (during the council after the battle of the Pelennor fields) that Sauron would never think somebody would want to destroy the One Ring.
It's possible that Gollum's prolonged search for the ring allowed it to maintain a significant power over him, suspending his aging process. In contrast, Bilbo's exposure to the ring's influence waned after he willingly (mostly) relinquished it, allowing his aging to resume more noticeably.
Elrond is a descendent of all 3 High-elves clans. He is also a far descendent (1/16) of Melian, a Maia (An angel/god magical being). He would probably be way more powerful than Thranduil in many ways, especially with Vilya on his finger !
Sauron's rise to power in the Second Age is portrayed in the Amazon prequel series The Lord of the Rings: The Rings of Power. He first appears disguised as the non-canonical human character Halbrand, and then in the second season as Annatar (a canonical alias of Sauron), both played by Charlie Vickers.
Everyone is going to have a different answer but, for elves, I assume this: The human equivalent is x5 up to 'mid-twenties' bracket. So, a '16yo' is 80 years while a '24yo' is 120 years. After that, the aging process essentially stops.
“Thranduil developed feelings over 2 years (12 in human) into their marriage but she 'rejected his love for her' and ran away while he was at war, leaving infant Legolas alone, and that when Thranduil found out he finished the war and quickly returned home, and ordered her to be found, but she was captured and tortured ...
IIRC Cirdan is the oldest known elf. It's possible (though unlikely) that he might have not been the oldest elf of his people despite being their leader.
Are Fili and Kili half-elves? Fili and Kili are not half-elf. They are the maternal nephews of Thorin Oakenshield, the dwarf, and are themselves dwarves of the line of Durin, the Longbeards.
Behind the scenes
Tauriel is a non-canonical character invented for Peter Jackson's The Hobbit film trilogy, and not mentioned by J.R.R. Tolkien.
The Posttraumatic Stress Disorder of Frodo Baggins
J.R.R. Tolkien in The Lord of the Rings accurately portrayed the signs and symptoms of what is currently labeled Post Traumatic Stress Disorder. Frodo's condition logically follows his experiences of less than a year in the War of the Ring.
Peter Jackson, the director of The Lord of the Rings film trilogy, made the decision to cut Tom Bombadil's character from the movies, primarily for narrative reasons. According to Jackson, Bombadil's scenes in the book, while intriguing, did not significantly advance the main plot of the story.
The clearest same-sex relationship in the novel, in the eyes of scholars, is that of the ringbearer Frodo Baggins and his servant, originally his gardener, Sam. Tolkien described their relationship as like that of an officer in the British Army and his military servant or batman.
