An absolutely filthy and disgusting place.  Blood from the recently tortured covers the floors and walls, and the place is generally filthy and grimy.  There are various pieces of torture equipment lying around the room as well as instruments, tables, and chairs.

the recently tortured
I have been captured and held against my will. I have just been put through large amounts of pain. There seems to be no escape for me from this prison.
You are merciful, I knew it! I've told you all I know about the plot to murder the Duke. Let me go now and I'll lead you to the cell leaders. What are you even doing, I am the dungeon master here? Let us proceed immediately! The next meeting is in an hour, we must move fast! Has the torture driven you mad? Have we not come to an understanding! The Duke is in danger! You must act now, free me! Simply spouting nonsense to attempt to get out of your sentence, yet you seem to expect there to be mercy. Alas, what else is there I can do to prove I tell you the truth? You seem to forget your place. Well then, I shall defend myself against this unjustice. Thief, hold his arms! Struggle as you will, but your time here has made you weak. Weak, eh? You think you can break me? You think I haven't dealt with toads like you my whole life? You think this knife will save you, think again. -slashes a finger off-
