From the introduction:
Theatre of the Damned is a short scenario best suited for characters in their first or second careers, but it can be easily modified to suit any group. It takes a day of PCs time and can be finished in one session. The scenario is placed in Nuln but with very minor modifications any larger Imperial, or Bretonnian, town could be used.
Theatre of the Damned consists of three acts. First, some background to the scenario and a brief synopsis are given, followed by the actual adventure. These are followed by descriptions of all the key NPCs, and a map.
