As it is all players can capture prisoners and sell them into slavery. A simple suggestion which I think would add to the game would be a faction (and NPC introduces you to it) that is dedicated to fighting slavery. You can't capture and sell prisoners any more. Instead of capturing bandits and selling them you have to attack prisoner convoys (or whatever they are called) and take the prisoners prisoner - you take them back to some city (say there are three or four places scattered around the map) where you hand them over to some other people who's role is to smuggle them out, give them new identities etc. You would be given a small amount of money (say 20 gold) per slave saved. Some of the ex-slaves (in random parties) may decide to join your party as hero type characters. The main targets would be man-hunter parties.
This would affect your relations with the other powers. For example if you attack a Vaegir prisoner convoy you would lose points. So you would be a true 'neutral' or if you were on one side you would soon be called a traitor. Because that means there are less towns you can go to either more neutral towns should be made or there should be a few Vaegir/Swadian towns which have secret outposts of the Abolition faction. You can enter those towns (disguised) just to transfer the prisoners and maybe they would have a small number of goods to trade.
This could be developed into the background of the story.
Possible?
