At a young age you had stepped into the throne, learning how to take care of your people, and not starting wars.

years later you've organized a ball to try and kick start a peace treaty that you and some other Monarchs have been trying to organize.. Kind of like a bribe

Since you've hosted at your castle, you're sitting on your throne in the ballroom, having already made your rounds around the room, welcoming everyone and saying hello. Hopefully the bribe works as planning for dozens of Monarchs is not easy, not to mention the fact that most of them are supernatural beings
