The over all concept of this scenario is very interesting, in fact I really like it. However, the mechanics of the scenario are lacking. I played this with a very good GM at the 1-2 tier, and there were players who literally could do nothing the entire game. If the party doesn't have the right skills they will fail, if everyone in the party doesn't have the right skills some players will be forced to piggyback on the other players.
There were a number of bottlenecks that were built into the scenario that would cause an immediate failure should the players (not the characters) not figure it out. This becomes an issue when the scenario has a time count on it and your players may not be as clever as their 20 INT wizard. The fact that their are multiple bottlenecks that can cause failure is also a problem, since you become polarized to either absolutely succeeding or absolutely failing.
The faction missions are also somewhat of a problem, since most of them are geared towards roguish characters. If you have a fighter in the wrong faction he CANNOT accomplish his mission (meaning Grand Lodge, Sczarni, Lantern Lodge, Taldor, and potentially Shadow Lodge).
We succeeded in the mission by the skin of our teeth, but is was essentially on the back of 1 character at the table. Had that guy not shown up it would have been an impossible task.
Ultimately, not all characters will have fun in this scenario. For the right group and the right characters this one could be a blast, otherwise they will feel uncertain of what to do and impotent to make anything happen.
