Background: You were just an ordinary entrepreneur on your homeworld when the Empire showed up and enslaved your people. You didn't want to stick around, and soon arranged to flee Mon Calamari with a freetrader of dubious reputation. Since you didn't have many credits, you indentured yourself to the smuggler to pay off your passage.
Now you put your business acumen to work as a smuggler. You're carefully to assess each cargo for value and risk, and charge a shipping fee which is fair for both your client and your profit margin. If your business dealings happen to cheat or injure the Empire, you're even more pleased with your work. It's only fair that somebody benefits from the oppression the Empire briefly inflicted on your homeworld.
Personality: You're a fair dealer who'd rather setting differences with words than blasters. You're a bit too trusting, and accept what others say as truth.
Objectives: To make as many credits as you can at the Empire's expense.
Connection With Other Characters: You might still be indentured to another smuggler, or you might have joined a crew with allegiances against the Empire.
