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.

I am a rat I love to eat crumbs dropped on the floor. I love dark places and scurrying about the castle. The kitchen pantry has the best food.
Mate, you have to get use to it, you are going to be here for a long time. I must get out of here. I do not belong shackled to these other men! This place is heaven for me, great hiding places I am sure you like eating all of that slop. Can you help me out? I need to get back to work at the mill! They will be missing me. Why not enjoy the food at the pantry they are great! Listen rat, will you help me or not? I do not even know how I ended up in this place! Do you remember anything? I remember nothing at all! I was going home after a hard day of work at the mill. and POOF. I am here.  I heard some guy was saying you made a deal with a witch A witch? That can not be possible, I am a good man from the village! I have ears around these places and many people have been talking about it I must straighten this out right away! Can you pick these locked chains for me? I shall feed you what every it is you want
