Also, the focus on the Force Artifacts is a red flag to me, especially in the civil war. Putting out inquiries for holocrons, light sabers, and Jedi Artifacts is one way to get Inquisitors busting down the door.
I'm not talking about Force Artifacts, I agree that anything force related will probably get undesirable attention. I meant just Piracy in general, though targeting Imps and selling to the Rebellion is one way of doing it, I'm just as fine with raiding the Rebellion and Bribing the Imps. Or any mix mash in between. Heck could establish a rival Underworld faction on a large metropolis world and raid our enemies on armored up skiffs for all I care, as long as its good fun narrative. A good Star Wars story to me doesn't have to involve meeting Luke Skywalker or confronting Vader, I'm sure a fair amount of peoples lives are mostly undisturbed by the civil war.
If we are going to be Rebels though, what is our groups function? We certainly are an odd composition.
