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.
Royal Bathroom, Inside Castle

servant
I am a servant in a large house. I clean dishes and help the rich people get dressed. I live under the house in a cozy little room and I have lots to eat. My job is pretty good.
Sire, This is my job, my duty.  I have done this my whole life, and I can tell you, without a doubt, there are far worse than this. Tell me not such lies! I have seen combat the likes of which you and the landed gentry alike cannot fathom! I know full well the horrid stench of a mutilated corpse long after the body has expelled its last gas and waste. I tell you now, this... fowl beast in odor form is only slightly more palatable that that. Sire, prior to working in the position of helping Your Majesty, I worked for a Lord in the South.  For years, he rose such a stink that the cooks complained while making pie.   Tell me not of my enemies of the Southlands! Come closer to the latrines! Something has either died here, or the pipes are simply not functioning as they should!  I am sorry Sire.  I never meant to insult you, for it was the Lord that I was complaining about.  I have heard word that eating more vegetables may help with the stench.  Please, allow me to check the pipes. Get on with it! I should not have to repeat myself! Nor should I linger in a place with such a repellent smell! Please Sire, I will need to take a look under, er, you.  Perhaps the guard can fetch some potpourri?  You order ME to fetch YOU potpourri?! How... DARE YOU! I am the King of the Noble North Empire! I carved this empire out of blood and conquest! Guard! Bring this whelp to the dungeon that he might know his place! Guard?! Guard?....g-guard? Sire!  I am not speaking clearly!  I am sorry for being so imbecilic!!  Please Your Majesty! Guard? Why do you not rise at my command? Guard?  Sire!  What would you wish me to do?  Shall I fetch the Royal Physician? I... think I know where the stench is coming from. Do not fetch the physician. Fetch the Royal Mortician.
