Locate the caravan heading along the dirt pathways near the ponds, west of Marauder’s Bridge. Sounds of commotion from up ahead force you to interject in a fight between two caravaneers and a group of five bandits.

Despite their impoverished state, they share a reward with you as the quest concludes. Seven days later, the surviving merchant appears at Crow’s Perch, selling goods as a new merchant.
