The royal bathroom is a stone room with a long wooden bench and several holes and seats for royalty to take care of business.  There are some tapestries depicting rural landscapes hanging on the walls to give people something to look at.

servant
king
I am a king of the whole empire. I give rules and pursuit them. I am brave and fearless.
Aye tis your job servant. Please fetch me some leaves. The porridge from the fast of day break has left me a bit loose. Oh, yes, right away your majesty! Do make haste servant. I fear I have misjudged the edge of this bench. My royal robes are a bit spattered and will need cleaned as well. Goodness your highness, but right away. That's a good servant. You have been trained well. When you are done please help me to clean. Speak to no one of this Royal Flush. Yes... yes sir. Where are you from servant? Have you always been a porcelain personal assistant or did you make one of my staff mad? I need to make ends meet, sir. I just do what I'm told. Are you being paid well for such a dirty job? Your work is much appreciated of course.  Not quite... only about 5 gold per day. Aye 5 gold. That is no beggars wage though is it. How would you like to earn 8 gold a day? I'd be quite thrilled to earn that much, sir.
