Slaves
Slaves are a variant of citizens, but with much less freedom and dependent on submission to keep them in line and continuously working for the player's settlement. Those who have committed a crime may be condemned to become a slave if a judge demands so. If the slaves are not submissive enough, they may run away. Defeated enemies can also become enslaved, as well as citizens living in a settlement that you have conquered. More specifically, when the player conquers a settlement, they can choose to show mercy, ransack the conquered settlement or completely annihilate it. The last two options allow the player to choose how many citizens will be enslaved. Choosing to annihilate the settlement will allow a higher number of citizens to be enslaved, but leaves the conquered settlement reduced to nothing.
Slaves do not count toward the number of "subjects" living in a settlement, so buying more slaves does not bring the player's settlement closer to leveling up. Only standard citizens/subjects count toward that. Slaves, like normal citizens, also have needs that need to be fulfilled to keep them submissive. Different races have different requirements for being satisfied and staying submissive.
The player can free all of their slaves at any time.
