Mögr has asked you to continue your exploration of Zelem-melek to gain a more thorough understanding of this dangerous sector of Moria, beginning with the Wide Halls below.
'I must return to the Twenty-first Hall, but I must ask that you continue your thorough exploration of Zelem-melek. I imagine that you will find many objects of interest lurking in the forgotten halls.
'If you ever return to the Twenty-first Hall, do let me know what you find....'
The Wide Halls are at the bottom of the Great Hall of Durin.
You should begin your exploration of Zelem-melek in the Wide Halls.
The greater passages of Zelem-melek can be found by heading west along the lower hall.
You should head west from where you planted the banners.
You have begun your exploration of Zelem-melek.
