In Tolkien's mythology, the Elves, or the *Quendi* as they are known in their own tongue, are the firstborn of the Children of Ilúvatar, predating the race of Men. They hold a unique and central role within the legendarium, characterized by their immortality, profound connection to nature, and inherent wisdom. Unlike Men, Elves are bound to the world, or Arda, for as long as it exists, their spirits only departing their bodies temporarily upon death, until they are summoned to the Halls of Mandos in Valinor. The Elves are depicted as the primary bearers of knowledge, culture, and art, which they continuously refine and preserve. This is reflected in their creation of the three Silmarils, the most hallowed jewels in Middle-earth, and their involvement in the crafting of the Rings of Power. The dichotomy between the Elves' desire to preserve beauty and their inevitable decline as the dominion of Men approaches is a central theme in Tolkien's works, symbolizing the tension between the transience of life and the yearning for the eternal.
Fëanor, the creator of the Silmarils
Inventor of the Silmarils, the most valuable jewels on earth, and inventor of the Balantiri, the stones of vision, and other inventions, a clever, sharp-tempered, selfish character, and considered a bad brother. At the end of his great life, his father, King Finwë, was killed and the Silmarils were stolen by the Dark Lord Morgoth. Fëanor sailed with his sons and his people to Middle-earth to take revenge on Morgoth. In his anger, he went with a few guards to the stronghold of the Dark Lord Angband. At its gates, the Balrogs descended upon him and killed his guards. He remained alone, fighting them bravely until Gothmog, Lord of the Balrog, managed to bring Fëanor down with a fatal wound. After the fighting was over, the sons of Fëanor came and found Fëanor of the earth and took him away. After that, Fëanor died and his fiery spirit burned his body and he evaporated.
Fingon the Brave
He was one of the kings of the Noldor and was called the Brave for his skill in battle. He was the son of Fingolfin of House Finwy and he led the largest horde in the Noldor journey from Aman to Middle-earth. During the War of Countless Tears he fought with many Balrogs, among them the Lord of the Balrogs, Gothmog. After the fight, Fingon was killed by Gothmog after one of the Balrogs came from behind Fingon and surrounded him with sound. Fingon could not move and Gothmog came and struck him with his black axe and killed him.
Glorfindel
He was one of the most powerful elves born in the House of the Golden Flower in the city of Gondolin. He fought in many great battles during the age, including the Battle of Gondolin in the year 510 of the First Age. He fought the forces of Morgoth bravely with his fellow warriors from the House of the Golden Flower. After the battle was lost to the Gondolin, they began to try to withdraw. As they were withdrawing, one of the Balrogs blocked their path, but Glorfindel stood before him and faced him, giving the others the opportunity to withdraw. He defended himself and fought the Balrog bravely. At the last moment, he managed to wound the Balrog in the stomach, which caused the Balrog to retreat towards the rocky slope, but the Balrog grabbed Glorfindel by the hair, and the two fell deep into the abyss and died. Glorfindel's spirit traveled to the halls of Mandos, but because of his noble deeds and saving many of the Elves, he was revived shortly after and returned to Middle-earth as a messenger. To the Valar who gave him powers close to the Maiar and his next role in Middle-earth was more battles and he even fought the Warlock King and the Nazgûl.
Gil-galad
After the fall of Gondolin, he was made High King of the Noldor. After the destruction of Beleriand during the War of Wrath, Gil-galad founded the kingdom of Lindon in the far northwest of Middle-earth, roughly between the Blue Mountains and the Great Sea. He was the last king of the Noldor and was recognized as High King of all the Elves in the West. Many of the Noldor and Sindar Elves joined him. Gil-galad was one of the three Elven Rings of Power, the Ring of Velia. Gil-galad and Elendil, the leader of the Men of Númenor, joined forces and formed the Last Alliance of Elves and Men. During the Battle of the Last Alliance, when the forces of the Alliance were able to advance their siege, which lasted 7 years, Sauron had no choice but to join the battle himself. He fought with Elendil and Gil-galad. Gil-galad and Elendil were defeated, and Sauron was then defeated by Isildur when the Ring was cut from him.
Elrond
Elrond is a direct descendant of the Maia, which gives him some degree of sacred power. Later, Elrond became the bearer of one of the Elven Rings of Power, the Ring of Velia, given to him by Gil-galad. At the time of the Ring War, he was over 6,000 years old and was considered a highly experienced warrior. He was highly skilled in elven magic, including healing and vision. He was one of the greatest leaders of the Elves. Aragorn believed that Elrond had the ability to mentally resist Sauron. Elrond was in direct conflict with Sauron during the War of the Last Alliance and also in the attack on Dol-Guldor.
Galadriel
In the Third Age, she was described by Tolkien as the strongest and wisest of all the elves left in Middle-earth. Galadriel witnessed three ages of the sun in Middle-earth and was born in Valinor during the years of the trees before the sun and moon appeared. She is considered one of the oldest surviving elves in Middle-earth. Galadriel was of the Noldor, daughter of Finarfin, son of Finwy, king of the Noldor. Galadriel supported her uncle Fëanor during the exile of the Noldor. Galadriel also bore one of the three rings of power of the elves, the Ring of Ninya, which helped maintain and preserve their great power. Galadriel played a major role in repelling Sauron's attack on Dol-Guldor.
Fingolfin
He was the first High King of the Noldor in Beleriand and his brothers were Fëanor, Finarfin, Findis and Erimi. He was the strongest and bravest of them and had many heroic deeds. After defeating the Orcs in the Battle of Dagor Aglarib, Fingolfin maintained the siege of Angband for nearly 400 years, but the siege was ended by Morgoth's attack in the Battle of Dagor Bragolak. As a result, many of the Elves migrated. In the end, Fingolfin went to Angband alone and called Morgoth to come out to face him in a one-on-one duel. Imagine this: one of the Elves challenges Morgoth, who is one of the Valar and the Dark Lord and the most powerful being. Morgoth accepted the duel and put on his black armor and took his giant hammer Grond and came from the gate of Angband. Fingolfin drew his sword Ringil and began the duel. Fingolfin was able to avoid all of Morgoth's attacks and wounded him seven times, but after a while, Fingolfin began to tire. Morgoth struck him down three times, but once Fingolfin would rise and fight on. But as Mandos once said, no force of the Elves could defeat one Morgoth of the Valar. At last he fell backwards into one of the pits of the earth that had been dug by the blows of Morgoth's hammer. Then Morgoth stood on Fingolfin's neck and finished him off. In a last desperate attempt, Fingolfin managed to slash Morgoth's heel with a deep wound that left Morgoth lame and in pain in his foot forever.
Ecthelion
Lord of Gondolin and leader of the Fountain People who led a wing of Gondolin's forces during the Battle of Countless Tears which was a catastrophic battle for the elves, and his greatest achievement during the Battle of the Fall of Gondolin and it was said that his voice was terrifying when he was giving orders to draw swords and attack the enemy forces* and his name became feared among the enemy ranks* and it was also said that during the battle Ecthelion and the Fountain People killed more Orcs than in any battle in all the battles of the elves and Orcs combined, after that Ecthelion killed three of the Balrogs he went to the King's Fountain to drink from it and regain some strength but he was confronted by the Lord of the Balrogs Gothmog and the two fought but Ecthelion lost his sword and when Gothmog was about to kill him Ecthelion ran towards the Balrog and pulled the sharp part of his helmet to Gothmog's body and the two fell into the spring and drowned, which Ecthelion did in this battle He changed the future of Middle-earth because the equal of Gothmog in Middle-earth is Sauron so imagine if Gothmog had survived and stayed into the Third Age and allied with Sauron it would have been much worse.
