It's very rare that you come across a module as well put together as this. It offers a dynamic, almost sandbox-ish story that has a real opportunity to get your players invested in what is going on around them.
The obstacles presented in this story have a unique openness in how they can be handled. Often, the enemy they face is overwhelming, so the player have to out-think, or be selective in how they fight. This creates some truly dynamic encounters, and opens up great RP opportunities.
