You have repelled an attack on Zudrugund by the Grishgúk uruks, but Nár's curious behaviour before the attack causes Corunir concern.
'Before the attack, Nár became very excited, and no amount of calming words from Frithgeir could settle him. He moved from shelf to shelf in a certain section of the library, and in his agitated state, I could not even get his attention!
'I will point out to you the shelves. Perhaps, this time, you will find some relevant information that will help us get to the bottom of our mysterious dwarf!
'The shelves are on the upper level, on the north side of the library.'
The book-shelves that so agitated Nár are on the upper level, on the north side of the library in Zudrugund.
Corunir has noted the book-shelves that Nár spent so much time at in the moments before the attack and wants you to search them for information that might be of use.
Nár is in Zudrugund.
You have searched the book-shelves pointed out to you by Corunir, and should speak to Nár to see if he can shed any light at all on what you found there.
Corunir is in Zudrugund.
You have spoken with Nár, but yet again he has provided very little with which you can piece together a solution.
Halbarad is among the huts on the western side of Lhanuch.
You have defended Zudrugund from the uruks, and Corunir now wants you to report of your success to Halbarad.
