Finding the man who spoke out about the true thief was easy enough, as he was still there playing with his dog. The pup found you first and alerted him of your arrival. "Hoi. Much luck with that kobold?" As you ask about the adventurer who had her items stolen, he would point you in the direction of a larger training area. "Aye, I vaguely remember seeing her. Some noble lass if I had to guess. She had the airs of someone who's just doing this work for the adventure and not the money. Last I remember she was talking to the leader of this camp and trying to organize some search for the thief. As for the thief, I honestly don't know where he went aside from outta the camp. I don't remember seeing him leave with anyone though... In hindsight, he might've just been a bandit."
