Thurindol believes that there are even more enemies beneath the Slag-hills and asks of you to investigate.
'I tell you, ${PLAYER}, I have wondered whether I were going mad. I would track an Orc Captain climbing the nearby eastern hills, only to lose track of him. Then, as if by some sorcery, I would espy him far west, where I should surely have seen him pass.
'The riddle has evaded me until now. The maggot-holes must communicate in tunnels deep beneath these midden-heaps, and access fundaments beneath the Towers of the Teeth, as well. It is the only answer!
'Will you investigate? Find a way into Carchost and discover what pathways lie below.
