If there was one bad thing to say about this adventure, it's that it was too good!
The DM has to work hard to get the full value of this module because there is so much going on at the same time. The reward is well worth the effort though, as your players will light up at the feeling of being immersed in a city where things are going on all around them whether they are looking or not.
This story-driven adventure is a nice change from an event driven dungeon where sometimes you get the feel that the monsters were "in stasis" waiting for PC's to show up and deal with them.
This adventure is full of plots, side-plots, plot-twists, rumors, and red-herrings and it is a lot of fun for the group to try and separate fact from wives tale, important from meaningless, to slowly uncover the trail that leads to what is really going on.
