|Gimli as portrayed by John Rhys-Davies in Peter Jackson's film adaptation|
Gimli (b. TA 2879) was the son of Glóin (brother of Óin) and a descendant of Borin (of Durin’s Line). In 3018, he went to Imladris, where he was chosen to represent the Dwarves in the Company of the Ring.
Among the many notable deeds of Gimli, he was most famed for his relationship with the Elves, with whom Dwarves did not generally get along. He was the first Dwarf to enter Lórien since Durin’s Day; upon laying eyes on Galadriel, he devoted himself to her, and throughout the course of his journey, befriended the Elf Legolas, earning him the title of Elf-friend.
When the Fellowship was broken at Parth Galen, Gimli traveled with Aragorn and Legolas to Rohan and fought with them in the Battle of the Hornburg. The trio later traveled the Paths of the Dead and arrived in Minas Tirith to fight in the Battle of the Pelennor Fields.
Following the War of the Ring, Gimli brought a group of Dwarves from Erebor to Rohan and became the Lord of the Glittering Caves. He forged new gates of mithril and steel for Minas Tirith and remained friendly with the other members of the Fellowship. After King Elessar’s passing in FO 120, Gimli sailed with Legolas over the Sea (the only Dwarf to ever do so).
