A very solid adventure with good direction and Warden notes to work with. Can see this being very easy for a first time Warden to run.
+ Great idea with dividing the adventure up into pacing stages than just locations and stat blocks
+ NPCs have a nice bit of quirkiness to give them some identity
+ Fun take on the undead horror, giving them more intelligent capabilities
