I would like the ability to "free" purchased slaves, and have the description change from "Female/Male SLAVE of {insert colony name}" to "Female/Male COLONIST of {insert colony name}"
In addition, it would be fantastic if "freeing" slaves gives a positive boost to colonists, in the same vein as "banishing" a colonist provides a negative.
Thanks!
If you buy a slave from a trader. They are treated like colonists and are controlled like one in vanilla when bought, outside of some mods... I think...
The Simple Slavery mod allows you to free a slave. They may run off and try to escape when you do this (and you have to arrest them again) or they may instantly join your colony as a full member.
Thank you both for the replies!
