'Much of Mazog's ramblings in the depths of Rushdurinul could have been empty bluster, the boasting and threats of a caged animal. But one thing he said troubles me more than any other: the revelation that the reward he seeks is the rule of another kingdom. Long have the Orcs and the dwarves battled in the caverns beneath the Misty Mountains, and the lineage of Mazog has been at the forefront of that conflict.
'If Mazog, son of Azog and brother of Bolg, has decided to abandon rule of Moria, it can only be because he feels Moria will no longer be fit to rule. What great evil must his ally Gorothul have set into motion in the depths that could so devastate that vast kingdom and make it unfit even for the rule of Orcs?
'Return to Gwathrendath in the Foundations of Stone and speak with Lenglammel and Forglinn there. They have spent a great deal of time in the depths and may know something about what we might be facing.'
Issuriel worries that the words of Mazog may reveal a hidden threat to the Elves of Lothlorien and the Dwarves of Moria.
Lenglammel and Forglinn can be found in Gwathrendath, the Elf-outpost in the depths of the Foundations of Stone, in Moria.
Issuriel believes that Gorothul may have set into motion some evil that might ravage Moria in such a way that even Mazog is seeking another kingdom to rule.
Broin is in the Peaceful Path, located off Durin's Way.
The Elves in Gwathrendath agree with Issuriel's assessment that Gorothul set some evil into motion before leaving for Dol Guldur. Broin should be notified of this, for it concerns the Iron Garrison and may affect his plans for the rescue of Bori.
