I've just finished mastering this one, and I'm really very satisfied. Very nice to finally play bad guys, and the adventure takes full advantage of the situation created. I've played it with a novice group, and it should be noted that it is a bit difficult for unexperienced players, and I had some trouble with level advancement, but really minor problems on an everall excellent experience!
I almost finish this, looking forward how the PC will behave on the final encounter... It is a great adventure, and a great AP start; my PCs never played an AP before and were absolutely in awe to this: great NPC, great plot, and a lot of staging for things to came, definitively a must have
