Jay is one of my favorite writers of D&D modules. He always creates intriguing, fast-paced, compelling stories, NPCs, and combats.
One of my favorite elements is that the PCs are given different specific tasks in addition to the overall goal... and some of those tasks compete with one another. It's so fun watching the players slowly figure out that they are at odds and letting them figure out how they are going to prioritize and work together. Its an added layer of depth that you don't always see in these kinds of modules, and it's really well done.
There's a ton to work with in this mod, and it's open-ended enough that the PCs' activities have a significant impact on the outcome (something else you don't always see in mods like this). I've seen or heard about several different sessions of this adventure, and every single one has turned out incredibly different. I really love that; it gives the players the feeling that they are actually having an impact on the events, not that they are being railroaded to a set conclusion.
Get this module. You won't be disappointed.
