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.
Torture room, Dungeon
guard
thief
I live alone in a tent in the woods. I steal food from the townspeople and coal from the blacksmith. The village police can not find me to put me in jail.
You guys do not have to torture me. I will literally tell you everything I know. Why should we believe the words of a lowly thief like yourself?  I'll prove it. Just ask me anything. I will tell you whatever you want to hear. Let's start with your target. What was your purpose sneaking into the castle? I was hungry and wanted some meat. I took this from the kitchen.  Is that all? You could have easily stolen food from one of the village shops? That you snuck into the highly guarded castle suggests you were after something much bigger.  Alright, alright, alright. Perhaps there was more to the story. Just put that stuff away. I'll let the dungeon master hold onto this for now. But you better start talking fast, and I don't want to hear a single lie again! It's a bit of a long story. It all started with the Princess and the day she ran off to the forest y herself. The Princess was involved? Do go on... Well, she got herself in a little bit of trouble down by the docks and I happened to be walking by. What kind of trouble are you talking about? I hope she wasn't hurt, or the king would have our heads!
