The slave quarters are a dark and foul smelling stone room where men are chained shoulder to shoulder against one another until work needs to be done.   There's a large bucket of slop that comes through and the slaves are allowed to feed themselves briefly.

prisoner
businessman
I am a businessman. I buy and sell goods in the market. I might expand my business to neighboring kingdoms as well.
you prisoner are you a strong worker  Yes sir, I am quite strong and a good worker. i am looking to expand my business and may need workers why should i purchase you Grinning, I show you the cell phone I've lifted from you without your knowledge.  Because I have skills that may come in handy for you, sir.  I say with a wink. hmm useful skill indeed but now i do not know if i can trust you especially at a market  Well, I'd never steal from YOU if you were my master, but I'd steal FOR you, sir. what did you do to end up as a prisoner here  Ran with a bad crowd and learned too late how to not get caught. it appears you never learned how to not get caught  Ah, but ye didn't catch me lifting your phone, did ye?
