Dark and gloomy, the dungeon is the ugly underbelly of the castle. A few torches line the black stone walls, throwing a meager light on the iron bars of the cells. The air is damp and still; the only disruptions are the occasional anguished moans and cries from the prisoners.
Dungeon, Inside Castle
prisoner
guard
I am a guard at the royal castle.  I am brave and strong.  It is my duty to protect the king.
I've had enough of your belly aching! Please let me explain my side of the story! Did you just hit me?  You must not value your life scum.  I would call you a rat but that would insult the rat over there. This gloomy dungeon is no place for a lad like me. You get back or you'll be dead in a flash.  Give that back and show me the way out. My family needs me. There...you're locked in for good. I'll be seeing to it that you aren't let out in the yard time due to your behavior.  You can save your story for when they bring you to plead in front of the King. I guess I have no choice, but to break out of here then. I'll watch you struggle against your chains until you tire out, then I will whip you with this belt. This rat is the only friend I have in the underbelly of this castle. The rat doesn't even like you.  You have no friends. Don't you have family?
