We've managed to take back the mine, but several goblins remain entrenched in parts of it. I suspect they're making new weapons out of the remaining resources.
Go and deal with those Nightmare Goblin Laborers and Foremen once and for all. Destroy all of their tools and take back the broken chisels and smashed magic stones. That way they'll be left with nothing to use for their nefarious purposes!
Well. That's it! Off you go, now--shoo! Marie gives you a decidedly firm push in the right direction.
How am I supposed to carry out my investigation with all these distractions, ay? I'd really like to know!
Oh yes, SOMEone said they'd bring me goblin tools and ore, but what's this? Your hands are empty, Marie says with more than a hint of sarcasm.
I thought I was pretty clear--one, destroy the Nightmare Goblin Laborers' mining chisels; two, smash the Nightmare Goblin Foreman's magic stone; three, report back to me!
And yet, here you are, skipping the first two steps and going straight to three. You can do better than that!
Saermon puts you to shame when it comes to following instructions, and THAT'S saying something.
