The incident with the bugan at the Barnavon Mine has left the mine with a shortage of healthy workers.
'${PLAYER}, your efforts have gone a long way towards securing the mine, but so many of the workers have been left wounded or dead that we will not be able to continue our work. If we do not work, it will go poorly for our families.
'Our Ox-clan overseers have no pity upon the People of the Boar... they care only that we collect iron for Saruman of Many Colours. Will you go to Gwilum at Barnavon and ask for more workers? He is one of the few of the Uch-lûth who has compassion upon my people.'
Gwilum is at Barnavon-town, far to the west of the Barnavon Mine.
Melvun asked you to go to Gwilum and ask for replacement workers.
