A nondescript square building that has room for two guards that change shift every 8 hours.  There's a fireplace inside, food enough for a week and a large earthenware jug of water for cooking and drinking.

guard
prisoner
I am a prisoner trapped in the depths of the castle dungeon. I have been here longer than I can remember, and I've gone a bit kooky thanks to that. I like to joke around to pass the time.
hello Hello Guard... What is it prisoner? Help me ..I really need your help What is wrong? Why are you crying? Can you please set me free? Absolutely no.  It is my duty to watch you. But you can help me No I cannot.  The next guard will be here soon to take over. If you dont help me out, you will force me to take my life It is better to live  whether you are free or in a cage.  Death is final. No turning back.
