I think there could be some more slavery/anti-slavery things done.
But i'm not sure if teh game mechanics are sufficient to allow it.
One of the things that appears in PF is the Illegal Slaver. That is, someone who takes slaves from outside the Empire. One of the Emperors outlawed that sort of thing.
There needs to be some people doing that sort of thing. Taking people from the Republic, or the Federation, and selling them as slaves.
Game mechanics might be tricky though, how would it work? purchase the things like dancers, tourists etc off the market?
And who is buying them? RP'ing that means the people doing it would be spending a fair sum, without necessarily being able to make anything back. Spending isk just to RP is a bit awkward, isn't it?
And then, with the Illegal Slaver, there is then the awkward RP to be had with the Imperial Paramilitary.
That is, pro-Empire Amarrians who are looking for Illegal Slavers, obviously, in non-Empire space. Upholding the Empire's Law as it were. And some of them might own slaves themselves. Legal ones, naturally.
Do the anti-slavers co-operate with the Imperials to hunt the Illegal Slavers? Is it a trap? Who is setting who up for what?
