Trader Massacre Quest Overview
Like the Trader Rescue side quest, this is unlocked after completing the Find The Bandit Seeress main story quest. But unlike the Trader Escort mission, you are basically required to do the exact opposite and aid the bandits and butcher all the good folk that stand in your way.
If you decide to take this quest over the other then you must head off to the Barrow Fields and commence the massacre of traders, civilians, guards, pretty much anyone that isn’t a bandit because they will be helping you along the way. This is quite a quick side quest so don’t expect to be slaying hapless victims all night.
When you’ve finished with all the bloodshed a cutscene will play showing that there is a single trader remaining, and you’ll have the choice of either letting him go free or striking him down for good. Seeing as how you’ve butchered so many, why stop now?
Whatever your decison, you will receive 5,000 Gold and 400 Renown upon completion of the quest.
