Mithrandir has studied the artifact that Ayorzén stole from the vault of Durthang and believes that if it might be cleansed of its corruption it could be empowered with a force for Good.
'The origin of this artifact is no mystery, Player, for its shape and the runes upon it state as clearly as possible from where it came. This key opens a door in Moria, in Khazad-dûm.
'But which door and where? That will be the real mystery. Perhaps the best place to start is with the Iron Garrison. Look for dwarves in the Twenty-first Hall that proclaim themselves lock-masters, and they will no doubt have a catalogue of locks to which this key may fit. Unlocking the door may cleanse the key of its corruption.'0/1

'If you are seeking the master of locks himself, you have found him! I am Greith, and I have taken it upon myself to open every last one of the hidden chambers of Khazad-dûm! Progress is slow, for now, but it would be slower for any other! Have you discovered a door that needs opening?'
You tell Greith that you have the opposite problem: a key but no door.
'Ah, then you truly have come to the right dwarf, for I know of several such doors that might be opened by this key you carry. But what is wrong with it? It causes a sickness to rise in me, and I feel a terrible dread in its presence! This is very unusual for a dwarf, and upsetting. If the key is possessed of such corruption, what evils might lie behind the door it opens?
'We will worry about that when we stand in the threshold... if even then! For now, let us try the key in doors to the south-west of here. A series of staircases descend, and there are locked doors on many of the levels. This strange key may unlock one of them.'0/1
