[The Mouth of Sauron]

With Durin's Bane killed by Gandalf and presumably only a few Orcs left in Moria after Sauron's downfall, did the Dwarves re-take Khazad-Dum ?

The suggestion in the LOTR appendices is that Durin the Deathless re-appeared and if so surely Moria would have been his kingdom ? Also remember Gimli in Dimrill Dale : "there lies the crown of Durin till he wakes".
