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.

spider
I am a spider. I am large, black, and have eight hairy legs. I wait to trap insects in my web. I enjoy eating unwary prey. I live in a darkened wood near a remote village.
Too late for regrets now mate, we stuck here for the rest of our lives Aye, and how did you end up here?  I'm actually here by choice, i enjoy the darkness and i have more food to eat here Thats an odd choice. Surely there are warmer places in this Kingdom than this decrepit and chilly dungeon? I have less  people trying to kill me here than anywhere else in the kingdom I see.. Well this is of now use to me now. Maybe you might some use for the silver coins.  Well.. as you can see i don't buy anything, but i can help you get it to your loved ones. Got any? None. They all abandoned me one by one. Looks like I will die alone in this terrible dungeon.  You might actually get lucky, just be at your best behaviour anytime the guards are around and the king might pardon you I may have better luck trying to dig my way out of here. The King has no mercy for bandits and thieves.
