LOTS of stuff going on this chapter, very interesting.
Balsimico planning to kill Halkenberg with some poison, and Kacho is gaining access to the other prince's quarters. I don't know if Luzurus is the one who put some curse on the girl since his inner monologue is just about the letter, but he is overly cautious, so who knows.
A lot of dialogue and more strings being pulled in all directions. Tsereidnech is becoming more powerful, alliances are being formed, and there's a plan in place now to take out 7th Prince Luzurus.
I don't personally think it was him that put this curse on her, I think it might be someone else ? Also the evil spirits that took over Kacho seem to mean she won't last very long, so I wonder if she is going to wither away by the end or not. I kind of doubt it, I think she'll be fine.
