Khazad-dum after the end of Sauron
 

After the Dwarves defeated Azog and the orcs at the battle at moria, thrain wanted to re-enter Moria, but it was said that they would not, for the world must change and some power other than theirs must first come to moria before Durin's folk could again walk there. Just wondering if that is sort of a accidental Prohpesy of Gandalf slaying the balrog? or was there another war of which I am not aware of, in which they entered moria after the fall of sauron and finished off the remaining orcs? you are the father of our folk, and we have bled for you, and will again.....but we will not enter moria

I've always wondered that myself. The history of Dwarves doesn't speak of their return, but I don't see why they wouldn't, especially with mithril to be had. And they had a suspiciously large quantity of mithril to rebuild the gates of Minas Tirith with...

I only posted to add that in the accompaying table of the Dwarves of Erebor to the aformentioned text Dúrin the Last is the Son of Thórin Stonehelm and the grandson of Dáin Ironfeet.
