I really like this concept. Slaving presents a challenge that anyone wanting to keep their reputation can't enjoy. And I agree with Badger on keeping it simple. It doesn't need a faction or a profession slot or anything like that. We just have to make sure you can't be both a Lawbringer and a Slaver.
Yeah. Same challenges and gameplay as slaver, but with the obvious disadvantages of your captives don't fight for you. I think that's a decent tradeoff. Maybe make it marginally less lucrative, maybe 30/40% less reward or something. I think people should be rewarded for being bad guys.
in this case... People should be rewarded for being bad-guys.
Does the Vortis Holding Centre operate as a slaver hub?
Since slavers are fucked over with buying/selling in klamath and modoc should the "lawmen" be unable to buy/sell in the den? I doubt metgzer would approve of someone selling to a lawman in 'HIS" town.
