Reward: 400 Renown, 5800 Gold.
After taking this quest to go Bowerstone North and talk to the female spy Tanya. She will give you some more information. Go north. You have to chase a trader convoy, and kill everyone except the guy with long moustache. Talk to him and escort him back to Bowerstone North. The only problem with this mission is the trader's health. He is fairly vulnerable and needs some protection (area attacks are good, as they attack many enemies at once), and preferably Heal Life.
