Búdan told you that there are others who may need your help in Angmar. There are tales of a hidden holding of the dwarves, east of Rammas Deluon. If the tale is indeed true, the dwarves have hidden themselves well, but Búdan fears it is only a matter of time before Angmar discovers them.
'There is much that we owe to you, ${PLAYER}. You have given us hope that one day we will throw off Angmar's yoke. There are others, though, in these lands that need such hope as well.
'There are tales and whispers that there are dwarves to the east of Rammas Deluon. If it is true, they have hidden there long and well, but as Angmar stretches forth its hand, they may soon find they can hide no longer.
'If you wish to discover if these tales are true, travel past Rammas Deluon and look for these lost dwarves. The dwarves' hall should be somewhere south of Duvuinen.'
The dwarf-holding lies to the east of Rammas Deluon and south of Duvuinen.
Búdan spoke to you of a hidden holding of the dwarves in Angmar and suggests that the dwarves could use your aid.
The leader of the dwarves is at Gabilshathûr.
