Lit only by scattered torches, The dungeon lies far underneath the castle.  Bandits and Thieves who find themselves there are met with cold stone walls and floors, with chains and bars restricting movement.  Guards patrol the corridors, keeping an eye out for any escape attempt or misdeed.  The only comforts afforded in the Dungeon are the piles of hay for sleeping.
Dungeon, Inside Castle

thief
I steal from people to gain wealth. I don't care about others. I am angry and mean.
Any way I can get out of here? HAHAHAHAHA! That's a good one! Welcome to the kings dungeon, thief. It does not hurt to try. It does actually. If I report that you're misbehaving, not reforming, or anything else of that nature, you get your sentence extended. So don't annoy me. I will do my best, it was just a simple question though. No simple questions here. Do your time, don't bother us guards, and you might just make it out of here. Annoy us and you'll be here longer. Annoy us enough, and well, you might get to meet my little friend here. Seriously though just one more question, is there any sort of work I could do around here to maybe lessen the sentence? I mean I do still have a family I would like to see. Shut your mouth thief! You're here to reform, and you won't see the light of day until you do! Fine, I will stop speaking. I was just trying to offer to change my ways, the last thing I wanted was to end up here. Maybe you should have thought about that before you stole. Well of course I thought of it, sometimes desperation makes people do bad things. And you think that excuses what you did?
