[LOTR] How did the dwarves thrive as a people after the one ring was destroyed?
gpt
Very well, thank you. The 7 had been either lost in dragonfire or gathered by Sauron, so unlike the Elves, none of the great Dwarven kingdoms suffered any direct consequences due to the destruction of the One.

After Dáin II Ironfoot was killed in the early stages of the Siege of Erebor during the War of the Ring, the Dwarves of Erebor were led to victory by his son, Thorin III Stonehelm. Thorin III had a descendant, Durin VII, also known as Durin the Last, who was held to be the last of the line of Durin. Durin VII led the Dwarves back to Khazad-dûm several centuries into the Fourth Age; with Durin's Bane defeated by Gandalf, they were able to reclaim Khazad-dûm. There they remained for a long, long time.
