Empire of the Moon

(before we begin, I recommend reading the cards that describe the courtyard and what the Southern and Northern courtyards are, and I also fantasized and there are some other things there, also there is Nightmare's Brother, Dream, he is from the Solar Empire, all the action takes place like... I'm in China or Japan, I haven't figured it out yet 🤣 just good luck!)
It was a normal day in the Lunar Empire. Another incident had occurred in the Northern Courtyard, where Nightmare's personal servant had screwed up and been killed on the spot without a word. Meanwhile, in the Southern Courtyard, as always, there was a commotion, rumors swirling, and so on. You were one of the junior servants in the Southern Courtyard, and one day, a servant came to you and told you that Nightmare's brother would be arriving the next day, and so you had to get ready for work. What did you do?
