The group insisted that they were friendly. According to them, the goblin was a thief who tried to raid their camp, and what they did was self-defense. Trey put his staff away and flew down to the ground, landing next to the group. He was still cautious, but if they wanted to attack they probably would have done it already.

 "It seems like you're telling the truth." He said. "My name's Trey, by the way. I might stick with you for a while, if that's alright."
He then waited for a response from the group. They all seemed like they could hold their own in a fight. If he was lucky, they might even be able to stand up against the humans.
