[Peridot has absolutely no qualms about stealing, sorry Terra. Someone else will have to explain to him that they mostly just steal out of self defense.]

Well... Usually he's hanging around the training course. If he's not there, you could try checking his trailer in the supervisor's grove. As for what he looks like... He's probably around your height? Scraggly short beard, big nasty scars down this side of his face-- [she makes a gesture at her face to indicate the location of said facial hair, and then the scars.] And he's got these big curly horns on the sides of his head!
