Glóin further explained the writings found on the sheaf of papers you recovered, which entailed a visitation by emissaries from Angmar.
'As I mentioned before, the papers spoke of visitors from the North, and at first I expected that they were Angmarim, like the ones we have seen crawling through the hills. It seems that the Angmarim here are not dealing with goblins at all, but rather great Uruks have come to Goblin-town to press the goblins into service.
'Vighar Roadwalker has a list of names that the Elves discovered among the papers. Speak with him, and perhaps he can offer you rewards for some of the goblins mentioned therein.
'I also would have you seek out the place where these visiting Uruks have been sent in Goblin-town and discover their whole purpose.'
Goblin-town lies to the north-east of Glóin's camp.
Glóin sent you back to Goblin-town to find the orders carried by the Uruks from Angmar to the goblins of Goblin-town. You will need to locate the place within Goblin-town where the Uruks have gathered.
Gloín awaits you at his camp just outside of Goblin-town.
You should bring the papers you recovered to Glóin so that he may evaluate them.
