The Spider-nest  

'Aye my friend, I know of a place where the quality you seek can be obtained. It is an ancient armoury belonging to the line of my own kin. Upon the anvil within were crafted many fine weapons.

'Indeed, I only yesterday sent an expedition of my fellows to reclaim this hallowed chamber, so there should be no problem with your use of it -- save, of course, for the matter of fees and recompense.

'However, before you even consider going to the armoury, you need to bring me an infused adamant, which I can prepare to receive the quality. Alas, I cannot tell you where to find one.'

A long-disused armoury belonging to Fastarr's forebears contains an anvil that would be suitable to bestow the quality you seek for your weapon, and a dwarf-expedition has already been sent to secure it.

Objective 1

Fastarr has asked you to bring him an infused adamant which he can prepare for use in bestowing a quality upon your weapon. Unfortunately, he does not know where such a stone may be found.

Objective 2

Fastarr can be found at the Dolven-view camp in Moria.

Fastarr has bidden you to travel to the armoury of his forebears and rescue his kinsmen trapped within from the ravenous spiders who have captured them.

Objective 3

Fastarr can be found at the Dolven-view camp in Moria.

You should return to Fastarr to complete the enhancement of your weapon.
