I ran this module 5 times at GenCon, or rather I ran the framework of this module. As is, there are huge sections that are unusable. It feels like an adventure who's author knew where they wanted to go, but somewhere along the way it got chopped up, shuffled around, and over condensed. I had a lot of fun with my tables, but I'm not sure how much credit I can give to the module itself.
Other reviews already posted have voiced most of my frustrations, so I'll just notate 2 specific one's here:
(A) There is a murder that happens near the PCs. No agency is allowed for in the PCs noticing or interfering. Then they are blamed for the event. Then they must use half-hearted clues to prove their own innocence. It's a rough section that's only sufferable if you cut out half of it and do a rewrite.
(B) The first combat encounter is actually pretty fun! The last one leaves a lot to be desired. If your party is at the APL 8 that is recommended, they should blow through it. Additionally, the PCs have (hypothetically) spent the whole module investigating an assassin who has all the spells to make quick escapes, but only uses them once the PCs have a chance to see the creature. Heavy railroading and the potential to frustrate your characters. The final fight (to avoid spoilers) involves the assassin casting 2 high-level spells at once and instead of fighting the assassin, your party will end up fighting an odd assortment of creatures that do nothing for the story at hand.
When I saw that this adventure was taken down once from the Guild, I had high hopes that it was getting a rework. Several adjustments could lead to this being an interesting addition to the series. Unfortunately, the rerelease offered no improvement whatsoever. Do yourself a favor and hold off on this one till it gets redone.
I will also notate my frustration with our unheard feedback. These are new adventures. GenCon is a huge event and dozens of tables ran this module. In the future, please, please use that feedback before you open up these adventures to the world.
