Inside the revolutionaries' headquarters, you will find a map of the castle and the surrounding town.  Also, you will find a long list of grievances against the King, both by his subjects and the Queen herself.  In addition, there are crates full of weapons and armor, as well as a small vial of poison.
hidden revolutionaries' headquarters, Inside Palace

duke
I am a royal duke in the kingdom. I have a lot of important duties, but I also get to enjoy some fun balls. I am very studious and polite.
My Queen, I have not seen your chambermaid, but I will help you if I can. What a dreadful place we are in. I belong on a soft cushion in a quiet, clean place. This sweaty armor disgusts me. Please take my cloak, it is freshly washed. Perhaps there's some reason you are here? I was looking for my chambermaid when I stumbled in here. What are you doing here? Um, I was looking for the decorations for the upcoming ball,and must have taken a wrong turn. Well, the King should really do something about cluttered rooms like this. Don't you think? I swear, sometimes he just doesn't do what needs to be done...Would you agree? Well, if I can speak my heart, there are some things that have been troubling me lately about the King. Oh thank goodness. I'm not the fighting type, but I was afraid I was going to have to stab you for finding this room. That would positively ruin my dress. Please, share your thoughts. Your husband, the King, has been ignoring the invaders who threathen our lands; I believe we must stop them . I've heard that you too have been questioning his decisions. Yes. I'm afraid he might begin to suspect. I can't find my chambermaid. She usually meets the revolutionaries for me, but now she's missing. Perhaps he seized her?! No, I would know if he had taken her. Perhaps she is dallying with the grooms. Some of us feel we must stop him soon. Would you be willing to aid our cause? Yes, but first I simply must find her. There are things I need in addition to being worried.
