Thurindol wishes to learn more about the creatures that bore the caverns below the Slag-hills.
'You say there is an insect in the tunnels that even the Orcs dislike. I wonder if we could use this knowledge to our advantage.
'If you happen to find yourself in the section of the cavern in which these maggots have taken up residence, perhaps you would be able to to collect their poisons.
'In studying the poison, we may be able to learn more of the creation of these caverns.'
Maggot larvae can be found within the caverns of Skoironk.
You should collect poisonous goo from the maggot larvae in Skoironk.
Thurindol can be found at a small Ranger outpost hidden in the Slag-hills.
You should speak with Thurindol.
