'The cave-claws are destroying the land with their rampant digging. Without some way to reduce their numbers, I fear the ground will collapse beneath our feet. Even the Dourhands are aware of the menace.
'If a few of the scourges were killed, it would prevent further damage.
'You will find the cave-claws around the caves and ruins of Thorin's Gate or inside the cave at Winterheight to the south of here.'
Background
The stone beneath Thorin's Gate is honeycombed by cave-claw burrows. If the damage continues, the entire area could be weakened enough to collapse in on itself.
Objectives
Objective One:
Orodlin asked you to defeat cave-claws found throughout Thorin's Gate.
Cave-claws are found near the buildings and caves to the east of Thorin's Gate and inside the Rockbelly Pit caves near Winterheight, south of the Elf-camp.
Objective Two:
Orodlin can be found in the ruins of the old Elf-refuge of Edhelion.
