Andrick does the same thing in his dialogue too. It's weird. He says that there's a goblin camp to the south of where you meet him and Ed and Brynna, but the goblin camp is west.
It's as if they originally intended the map to be flipped so what is currently west was once south.
If that's true, then the document Meerna's journal states that expedition 42 was to the northern quadrant. If south is west then north is east. Wouldn't that potentially mean expedition 42 is Decrepit Village?
Arandur was found at expedition 42, and if you search the map, you'll eventually find an arandur ring. So, it would make sense that "the northern quadrant" is actually "the Eastern quadrant" and arandur can be found in the collapsed mine shaft on the east side of the village. Also, talk to a duergar corpse and ask if he had anything valuable. He says no but mentions that the gnomes were digging in the rubble on the north side. So, north = east, and again, it fits. The gnomes were surely digging in the mineshaft because you can find their bodies there with duergar dead also.
So either they need to fix the game map or the texts/dialogues... Or so it seems.
