The Water-wheels: To Stagnant Nala-dum  

'The impertinance of the Elves is forgivable because of the hope Celeborn has kindled with the intent of his well-meaning message. I wish that I could invest every pair of hands in the expedition to re-igniting the lost lore of Durin's Day as our Elf-neighbour describes.

'Alas that I cannot spare them, for I know that fell rumours hiss from the deep wells of Nalâ-dûm where the water-wheels once spun; long ago did Khazad-dûm hum with the murmur of great power surges leaping across the caves. Celeborn's message has put a warmth in my heart...there must be a way to solve this problem.

'Bludless, will you come to our aid again? I would ask you to travel to Nalâ-dûm with a small company and defeat whatever menace lurks there, for something has destroyed the works that once pumped life into these silent halls. If you find anything of value while you are there, I would give you a sturdy reward for such priceless knowledge.'

Haldir of Lórien has sent you to the aid of Hrólfur in Moria, a deed that may in turn provide some security for the Elves. Hrólfur and Haldir hope to see the legendary mirrors of Lumul-nar functioning as they did long ago, in Durin's day.

Lumul-nar is in Zirakzigil, north and slightly east of the Chamber of the Crossroads.

Hrólfur, at the bidding of the Elves, has asked you to investigate Lumul-nar to discover why the light-sources no longer throw their beams through the dark halls of Khazad-dûm.
