While the sappers at Durin's Stone may have been stopped, they were still able to inflict severe damage upon the hallowed rock.
'You stopped the Orc-sappers, ${PLAYER}, but I fear you were too late. It is not your fault. I should have gone myself as soon as I saw them. Although Durin's Stone has been saved, severe damage has been done.
'While they were preparing to destroy the stone, they chipped off many pieces. It has been defaced and made the fool of. There is but one course of action for us to take: we must reclaim what is left.
'Head south again, back to Uruk-gashan and search for the broken off bits and pieces of Durin's Stone. Gather up what you find and bring the pieces back here. At the very least we can salvage those, and perhaps one day, make the stone whole again.'
Fragments of Durin's Stone can be found at Uruk-gashan, south of Mekhem-bizru.
