Oh he will, trust me. I have a few tricks up my sleeve too. As for you: I would like you to intercept this salesman and find out what he knows. If he is walking the southern roads then ironically he will somehow end up at the central guard tower again, so be sure to scour the southern road leading there to find him. If you do find him, don't attack him. I think it would be best to try and get him to reveal his true identity without tipping him off. Come back here when you've gotten a hold of something interesting.
