CMON Expo has some great events you can’t find at other conventions. A very popular one from last year was the Dark Age mega-battle, Siege of Fort Retribution.
About the event:
Hidden behind the imposing iron walls of Fort Retribution, Saint Johan is amassing an unstoppable army that if left to their own devices could mean the end for everyone else in the world of Dark Age. You and 7 other players must breach the walls of Fort Retribution and defeat Saint Johan. This will be no easy task as the forces of St. Johan will be driven by the master of all things Dark Age, Mr. Black!
