What about having one of those murder mystery balls? Where you could pick a theme say a Dustarian diplomat is murdered at a homecoming ball. And people come to roleplay and decide who is the suspect from a list. People could volunteer to play the role of the suspects and the person who dies. And others come there and talk to the suspects and generally roleplay the event that is happening in the game (feast/holiday/etc.). First person to guess who did it and has the evidence to proove it wins.
Only problem that I can see is it's hard to keep five or so people (suspects+killer+target) on for a long peroid of time.
