The flair for the dramatic is the best part of this adventure: "WHO AM i TO JUDGE" and "ANNIE LOVES ME" scrawled all over the walls in blood. A nanobot swarm shrieking "Long live the new flesh!" The fact that the Warden is meant to be in-character as Annie throughout. Not the most original idea for an adventure but it's executed so well.
The diegetic Warden -- are there any guidelines for making this work effectively, especially when you start getting into the technical mechanical details like hit points and body saves and whatnot?
