From the GaryCon Forums:
In the hilarious improv show, you'll help create the characters that will embark on the adventure of a lifetime to retrieve the famed Gem of Misfortune! This is a dynamic, highly interactive old-school D&D themed improv show you have to see! Bring your favorite monster and trap suggestions from any fantasy game. If you love stories of high adventure and epic failure, you must see us play them out before you in IRPMUS LIVE! - FANTASY!My brother and I will be attending the Wednesday show. According to the folks at GaryCon, this will also be a test to see how well the new ballroom would work with future cons. We'll just have to wait and see.
