Trader Massacre is a Silver Quest in Fable: The Lost Chapters that becomes available after you complete the Find the Bandit Seeress quest. Although they seem mutually exclusive, you can still do the Trader Rescue quest. A war is going on between the bandits of Oakvale forest and the traders. In this quest, you have to help some bandits kill all Guards and traders in Barrow Fields; after that is done, you are given a choice to kill the last trader or spare him.
