Lord of the Glittering Caves was a position created by Gimli after the War of the Ring. He led a large number of Durin's folk south to establish a new Dwarf kingdom at Aglarond where they became known as the Dwarves of the Glittering Caves. Led by their Lord Gimli, they repaired much of the physical damage incurred during the War of the Ring. Most notably, they rebuilt the Great Gate of Minas Tirith with a new one made of mithril and steel, as well as improving upon the existing layout of the entire city.
