Hi want to discuss the character of Gimili
Gimli, son of Glóin, is a Dwarf from the line of Durin of the Dwarves of Erebor. His father, Glóin, was one of the 12 dwarves who set out with Thorin Oakenshield in his quest to reclaim the Lonely Mountain from the dragon Smaug, as told in the hobbit. Gimli was born in the year 2879, about 60 years before the death of Thorin in The Hobbit. He was still a rather young man (by Dwarf-standards) during the events of The Hobbit, and thus not present in that book.
Gimli rose to prominence, both among his people and in the wider world, during the events of the War of the Ring. He was one of the Nine Walkers who set out from Rivendell with Frodo on his quest to destroy the One Ring. He came to the Council of Elrond, along with his father, with the news that Sauron's servants had been visiting the Dwarves of the Lonely Mountain, asking questions about Bilbo and the Ring.
Gimli is 139 during the events of The Lord of the Rings.

He later became known as Elf-friend, the only Dwarf to be given such a name, due to his great friendship with Legolas and his respect, reverence, and deep affection for Lady Galadriel.
