Needing ideas to play out a masquerade ball with our group. I'd like this to be an interesting and fun event, but I'm low on ideas. Here's the way it's laid out. A noble woman is doing a sort of social experiment by inviting members of all social classes to the ball. There will be 2 hours of dancing and whatnot while masked, and then there will be a big unmasking of all the guests. I've already decided that there will be things like some of the guest being attracted to the wrong social class and being quite startled at the unmasking. Things such as spiked punch or food are a thought, but what would be the effects? Shall we have a disturbance at the ball? My only problem is, I don't want this to de-evolve into combat, but it still needs to be entertaining. Any ideas welcome!
