Sintas
Few beings know what the infamous bounty hunter Boba Fett looks like under his battle-scarred Mandalorian Armor; fewer can claim to know the secrets of the man's past, or what emotions beat in his heart (assuming he actually has one; current odds in Cloud City are 2:1 he doesn't). The female bounty-hunter Sintas may be the only one alive who knows for sure.
She knows as much about the man as any wife knows about her husband, for in addition to being comrades-in-arms for a while long ago, they were wed and had a child. As with all things surrounding Fett, this is a closely-guarded secret, and he will go to any length to keep it that way.
Fett has worked alone almost exclusively since the two split. While their parting presumably was not amicable, Fett continues to be somewhat protective of Sintas, albeit in a detached fashion. A feared hunter in her own right, she rarely needs anyone's help to stand on her own. Nevertheless, she works less frequently now, usually only accepting jobs of interest or importance to her. It seems the thrill of the hunt only brings back painful emeories of "Bo".
Sintas is a strikingly beautiful Human in her mid 30's. A native of Kiffu, Sintas weras the symbolic facial markings of her people, which in her case are three straight lines on the lower half of each cheek. Her long black hair is tied at the back, and she generally wears practical and unassuming clothes. However, while she might appear innocuous enough, the two heavy blasters hanging from quick-draw holsters betray her deadly trade.
