Balrog vs 200 000 dwarves ?

Dimrill Dale)? Certainly he was lurking within Moria and well aware of what was happening outside - Dain saw it after slaying Azog just inside Moria's East Gate. I suspect that, while very powerful, the balrog was, ultimately, incarnate and could be slain, especially against a large, organized army. He was not by any means invinceable.

Yet Dáin claimed that "The world must change and some other power than ours must come before Durin's Folk walk again in Moria." I don't doubt that the Balrog was an incarnate being which could be slain (indeed clearly it was: Gandalf killed it), but apparently the Dwarves lacked the means to defeat it. If I was to suggest why it didn't aid the Orcs in the Battle of Azanulbizar my main suspicion would be that it simply didn't care about the outcome of the battle. I don't believe that the Orcs of Moria were the minions of the Balrog, they just happened to share Moria with it. Azog claimed to be king and master of Moria and made no mention of the Balrog. If the Orcs of the Mountains owed allegiance to anyone beyond their own rulers it was Sauron alone: "in many places in Middle-earth, after the fall of Thangorodrim and during the concealment of Sauron, the Orcs recovering from their helplessness had set up petty realms of their own and had become accustomed to independence. Nonetheless Sauron in time managed to unite them all in unreasoning hatred of the Elves and of Men who associated with them." (Morgoth's Ring) I would theorise that the Balrog never intervened in the battle because it didn't care about the outcome, having no stake in Azog's victory and knowing that the Dwarves could not defeat it. Evidently Balrogs could be killed, but the evidence would suggest it could only be slain by an opponent of comparable power which the Dwarves lacked. The most puzzling thing about Durin's Bane is probably why it was content to remain in Moria in any event.
