I do like Lanakov's idea of a slaver-focused Outcast faction, as well. The last truly interesting "villains you love to hate" slaver group-- Ah, really screwed up and made a very big mistake by referencing something unacceptable, even in RP, and was instantly nuked from orbit by the admins. It's too bad since they were good RP'ers, it's just that they decided to push Rule 1.1 too far.
But yes, slavers are typically your classic sort of villain that even other pirates may hate out of sheer principle. It may also be an opportunity to play off a seemingly-"good-guy" slaver in which the character may come off as an agreeable sort, it's just that-- Well, they happen to own slaves. Now, whether they happen to be willing or unwilling, that would be another thing to play with.
Food for thought!
