Cardin is a doctor trained in some of the finest Coruscant academies, raised (many years ago) by a wealthy family. He was teenager during the clone wars, aspiring to join the war when he came of age. The war ended before he could come of age, and he instead went to medical school.
He fell in with the wrong crowd, and its gone downhill since. That was ages ago now... he has since had a survivable career being a thug doc, hutt surgeon, and so much more. Usually barely cutting it, if that, and he has successfully survived multiple attempts at retaliation when he pronounces friends of thugs dead. (Sorry but, Blaster Turrets are rare to come back from.)
Bounty - 20 -
Cardin has made some enemies in his line of work. Early in his days of trying to scrape together as many credits as he could; he made a deal with the Black Suns. To infiltrate and poison a certain member of a Hutt Kajidic.
Cardin has white hair, above shoulder length. Depending on the night before, he can clean up well, or look quite disheveled. Although, he rarely seems to lose his keen mind, even if inebriated.
