 At the start of the Fourth Age, Gimli led a group of colonists from the Lonely Mountain to the Glittering Caves, beneath Hornburg in Rohan, where he established another Dwarf kingdom and ruled there for more than a century.After the death of Aragorn in the year 120 of the Fourth Age, he sailed to the Undying Lands with Legolas.It is told that a few centuries into the Fourth Age, Durin VII – a descendant (some sources say the son) of Thorin III Stonehelm – at last led Durin's Folk back to recolonize Khazad-dûm, where they remained "until the world grew old and the Dwarves failed and the days of Durin's race were ended".
