I've not listened to everything yet. I'm only on page 2. Still, Samad- Taim is very interested in slave affairs. His caveat for helping them is simply, some of them are criminals. Those to him, should remain slaves, not worked to death, not beaten or maltreated, over much, but they should remain as slaves. The rest, should be treated as the typical bondservant, working to pay off their bond. He however id not a man that fights the system directly, but rather wants to move the system, from within the system to bring about change. Don't fight the current, but use the current for you. He has a plan, that will change the face of how slaves are handled in the nation, but it will require knowing the right people, which at the moment he doesn't. Still, given that he periodically purchases slaves for various functions for the school (secretly to receive magical training, to serve as assistants, and helpers, etc), it wont seem strange for him to periodically tour slave holding facilities, nor will it be strange for him to occasionally talk to the slaves, and lend a little magical healing from time to time. That is of course, this meets with your approval.
