In our ongoing Warhammer FRP gaming group (full session videos on YouTube), the party is currently attending the annual Carnival celebration in Middenheim. Part of the Enemy Within campaign material is a great amount of events and details around the calendar of events for the 10 day festival, along with the notable NPCs that are present at each of the locations. Although the source book provides some basic information on each such encounter, for obvious reasons the writers could not fully develop all the details around all the scenes, as the book would have been far too large.
Thus, on the second day of the festival, there is a note of the local production of the Opera, the Barbarian of Vessille, which attracts a number of the notables from the storyline. For whatever reason, the group gravitated towards this particular show, but all of the basic material just gave a short summary of the actual play, with the focus instead being on other Carnival events. Since this had become a focal point for the group, I opted to spend some time to flesh out the details and build up the atmosphere. Thus, the full context of the production was written up, and the group experienced the story during our last session.
For your entertainment, I present my expanded notes on the Opera. These were presented in three acts, with a 15-minute intermission between acts, so that the group could interact with the NPCs of the location and follow along with their own subplots. In particular, there were group concerns about a terrorist attack, and several of the players were acting on those suspicions, while others were unaware and simply trying to reach certain politicians or nobility.
