The players talked about it. Two PCs - the instigator Alissa and the ex-pirate Xander - did it. (We already knew Xander was a ruthless individual. He didn't quit piracy because of moral qualms!)Maybe I'm not understanding the last part. Your account says that the players talked it over and it was decided that the pinnace should be blown up. Why are the murders just on her for those deaths? Wasn't it a group decision?
