B'Gorr runs the most well known and possibly largest black market in the galaxy known as the Black Bazaar. One could find anything they wanted there for the right price. B'Gorr and his crew treat their clients quite well, probably having better customer service than legal markets. They don't make quite an effort to hide their activities as they know that even government and military official are among their clients. Should anyone decide to shut them down, they would be met with substantial opposition.

Also, a bit of a comparison between the alien crime boss's size and most other species. He is quite large.
