I was setting up to play Blackbyrne's BP1 adventure (The Hidden Current) and used this as its intended prequel module. This could easily be dropped into any early campaign as its a rather universal theme (the PCs start by browsing around a local market, when a bad guy unleashes monster into the crowd. Chaos and mayhem ensues.) Battlemap scale images are provided and some NPC backgrounds are included if the DM does want to use as a transition module. My PCs definitely enjoyed.
