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.

I am a guard who watches for things at night. I live in a castle. I do not enjoy speaking with people.
How was the evening shift Captain? All quiet, praise the Maker.  I'm not sure if I could have managed another prison riot after how messy the last one was. Agreed captain, we were lucky to make it out of that one alive. I just don't understand why men like that think that cutting off another prisoner's fingers is *fun*?  Surely they realize their situation won't improve if they keep doing such atrocious acts Sir I assume they feel as if they have nothing to lose. The Queen herself has offered pardon and restitution for those who behave themselves.  They've a chance at another life, a chance out of their own misery, if they would just seize it. It's just not in their blood captain. Can I get you a drink captain? Aye, I could use something to part my thirst after a long night like that.  Thank you, lad. Absolutely sir. Here you go. Ah - very light and refreshing.  No aftertaste at all, this brew.  But enough about me - how are the wife and children settling in? I know this post isn't as cushy as where you were last stationed. Oh, they're holding up well sir. They are very easy going. Ah, she's a keeper then, that one.  Cherish a wife that will help you in this line of work, lad.  They're few and far between, let me tell you.
