Zul, is to, put it nicely, a greedy, evil bastard. She stole her first ship after a night as a courtesan. Her first night in that job, even. Since then, she didn't bother to fix it. So, it should be no surprise, in that it broke down after a few years and only was good enough for the scrapyard. Therefore, she was forced to borrow her ship in order to continue trading and exploring the galaxy!
She remains fairly moral for a trader though. Usually. She refuses to sell to the first order, hates slavery and is a nice person. Provided, you don't try to trade with her. Then... all methods are holy.
