The lavatory contains a long trough for which the knights can use for urination. Crude toilets are also included for defecation. The design is all stone walls with candles, and no privacy walls.

I am a king of the whole empire. I give rules and pursuit them. I am brave and fearless.
Wow, this lavoratory is filthy!  My apologies, Sire. Allow me to fetch a peasant to clean it. Thank you, knight. How are you today? I am very well. How are you today? Very well, just tired after all the negotiations.  Any favorable conclusions reached? Yes, we have gotten the tract of land that we wanted in the east, but we also want access to the port to the north. I assumed they declined your offers.  They have been resisting but we think that we can make the offer appealing enough. That is great to hear. May I ask who our heir is? The heir to the throne? That is quite sensitive info! I'm just wondering, sorry to have offended you.
