Ooh, where to begin? A subpar dungeon crawl. Monsters with "neener-neener" tactics and abilities and a final encounter which is simply overwhelming due to the boss creature's à la carte menu of "you die" abilities.
If this were in print it wouldn't be worth the paper it'd be printed on.
This is by far the best Pathfinder Society scenario I've played: not only is the scenario evocative it also oozes with atmosphere. Nearly perfect save for one particularly deadly combat and loads of fun to play.
