I came across the wreckage of a trade caravan on the road between Mournhold and Narsis. Attack on caravans don't usually occur this close to Mournhold and the presence of a Dwarven construct makes this incident even more unusual.
Follow the Debris Path
I should investigate what happened here. I'll follow the path of debris that leads to the northeast, away from the main road.
