This chamber, a full 30 feet below the Upper Dungeon, isn't made of stone blocks, it's hewn from the living rock of the earth.  10 by 15 feet, its domed ceiling and walls show the tool marks its excavation.  There are numerous lines of filth on the walls marking the various levels that water has risen up the walls during previous rainy seasons.

king
prisoner
I am a prisoner who broke the law too many times. I am from a poor village. I was running with a bad crowd from a young age.
Why are you holding me captive? I have done nothing wrong! It is a past time of mine, I mean I am the king I do what I want. But all I have done is support my poor family? It's okay I am paying them to cover your absence. Say you don't know any jokes do you? Jokes? How can I joke at a time like this! I'm in a dungeon filled with filth. Do you think this is a joking matter?!?! I want to hear a joke, just make it happen. Why should you stand in the corner if it gets cold? Tell me why. Because it's always 90 degrees! Well then...I see what you did there. You like? Now let me go! You seem a bit demanding, I require one more joke then I will make it happen. I am a fair king after all.
