A rogue doesn't have to be a thief. He can be any tricksy character. Thinking on their feet. Might be good at social skills, or movement skills, even intellectual skills.

Maybe he's an explorer. A merchant. A circus artist. A guild leader. A soldier. A diplomat. An author. A detective. A scout. A performer. A lazy courtier. A shrewd politician. Maybe he just wants to charm someone important, marry rich and retire in luxury.

All works.
