The treasure room had several corpses in it - three humans, and a goblin. The only one that had a dagger was the goblin, though, which meant the humans probably weren't responsible for the death of Backstabs' father. That didn't mean they were innocent, though. The fact that they were here meant that they were trying to raid the village.

 "There might be something around here that can help us find out what happened." Trey said. "Keep your eyes peeled."
He looked over at the human mage. He had a staff on him, which would probably be much more useful than the moldy stick that he was carrying around.
"I could make good use of this." He said as he began to pry the staff from the dead mage's hands.
