Mother Amma needs help finding a mysterious crystal.
'Welcome to Annâk-khurfu, ${PLAYER}! It is good to see that you are still doing your share!'
You greet her in turn and ask why she has left Erebor.
'Not due to any amount of disgrace, regardless of what that Zhélruka liar suggested. There is no overwhelming request for necklaces and baubles at the moment, and it was well past time for Authi to try his hand at running the family business. I have turned my skills towards the mending of armour and the boosting of morale of those on the front lines.'
She leans in, lowering her voice and grinning.
'Also, the depths of Gundabad surely hold gemstones of the finest quality, hidden deep in the bedrock where the enemy could never hope to find them.
'Now then, I have heard tell of strange, fell crystals in the enemy camp Zarkul-sulûn. Bring me back any crystals you find and let us see what truth there is to these rumours.'
Zarkul-sulûn can be found in southern Elderslade.
You should look for strange crystals for Mother Amma.
