Gloin tells me you have been working with him to discover why the goblins of Goblin-town have become so bold. I thought you would like to know that he informed me of a good number of leaders within Goblin-town that need to be found and disposed of to weaken the goblins' resolve.
I do not know where within the depths you will find these leaders, but when you do, you should deal with them expediently.
Goblin-town is far to the northwest of this camp, and you will find these goblin-leaders throughout the place.
