As long as we're discussing backgrounds.
Scorpius' family were minor nobles about twelve generations back, when they were forced to flee due to political infighting (his human side that is) at some point they ended up in Baccarat with little coin to their name. This is when the orc blood mixed in. The stories of his family were still passed on to him as a child but he has no idea that they're about him, they seemed to just be stories that were always told.
Being quite athletic, and enterprising Scorpius fell into pirating very naturally after doing any sort of work that came his way. He's really not a bad guy, but growing up in Baccarat it was always survival of the quickest or biggest. Taking what you need is a way of life. It's not wrong, because there's no other option.
