To be honest, I don't know, if I have the correct wording. I play LARP with my major Char for multiple years in Germany. These events are called "Conventions", where staring from around 60 up to 3.500 players come together, following a plot (story?). My character is full equiped, including background story etc. I am looking for similar events or "Cons" in the area of Chicago. Please let me know, when I am totally wrong here ...
