[Eomer of the Rohirrim]

In Khazad-dum, Durin was killed by the Balrog who had decided to settle there. The year later, his son Nain was killed, also by that very Balrog.

What exactly were the Dwarves up to over the course of this year? Was it a year of terror for the whole community. Or was Nain perhaps one of the last Dwarves to remain in Moria, overseeing the exodus?

Thoughts? Because I can't imagine the Dwarves hanging about Moria with a Balrog lurking round the corner.
