Nökkvi was horrified to discover that the Nameless have been feeding on dwarf-corpses and feels an end must be put to their desecration.
'Bellows and anvil, this is unacceptable!
'The bodies of our brethren cannot continue to feed these creatures. We will put a stop to it, or may my beard wither!
'The first step is to ensure the respectful treatment of those bodies. We must allow them to return to the stone of our beloved Khazad-dûm. Please, go inter them, then return to me.'
You found dwarf-corpses in the place called Mazam-dûm, on the eastern side of the lake in the Foundations of Stone.
Nökkvi has asked you to bury the dwarf-corpses you found.
Nökkvi is at the Shadowed Refuge in the Foundations of Stone.
You should return to Nökkvi to tell him of the burials you performed.
