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.

I need a new cushion for this throne! All this chatter in court is giving me a headache!  That Lord that just walked past offended my nose with his odor.  I need to find my chambermaid.
Hello duke. What are you doing in these headquarters? Hello my queen, as part of my duties, I am having a look about. What goes on here? I needed a break from my throne. I'm not sure what's more dreadful, the cushion or the odors. Ah yes, the duties of royalty are no doubt exhausting. Might I inquire about these maps? Is there something afoot?  Someone left them here. I dream of using them one day to escape for a moment of quiet. It would be nice to escape and not be found for awhile don't you think? Without question, I too enjoy escaping the walls of my life at an occasional ball or two. But aside the maps, I also see weapons, and what is this small vial? What does it hold? It appears to hold poison but I've no idea who it's for! I don't mean to pry too deeply, but it seems as though you are shaken and unhappy, you are vital to the kingdom. Please, tell me truthfully, what goes on here? For without more information, I must alert the king. You silly man. You have no authority to tell the king anything about me, his wife. As you can see from these lists I'm not the only one with grievances against the king. You are quite delusional to think he would even care what you have to say Foolish woman, you dare to conspire against the king? Now tell me who has helped you plan this? Tell me now, or I will take matters into my own hands! Who said I was conspiring against the king? You're quite the imaginative little man I see. Perhaps I shall tell the king that I found you here, adding your grievances to the list? Once he finds out that you have attacked me it will be off with your head!  He knows of your treachery, your duplicitous ways. I too am charmed by your appeal, but I shall not defy the rightful king
