Swerthir is fascinated by the Vault of Durin to the south, but worries about separating from his party.
'According to my map, ${PLAYER}, the Vault of Durin lies directly south of here. The problem is that my party refuses to explore it. They wish to head straight to the Dolven-view and not veer off the path.
'I should dearly like to know what lies in the Vault, but I dare not separate from my group. Will you go look, my good ${RACE}?'
The Vault of Durin lies directly south of the little encampment in Lamab-dûm, in the Great Delving.
You should find the Vault of Durin and see if it is as promising as its name sounds.
Swerthir is at the small dwarf-encampment in Lamab-dûm in the Great Delving.
You should return to Swerthir and tell him what you have learned about the current state of the Vault of Durin.
