I freally enjoyed this adventure, that is well designed, with great maps and with an interesting background. I swiftly adapted to the setting that I'm crrently using with minimum changes. The ruleset can be adapted on the fly quite easily as well.
I took the bones of the idea for this and moved it up to level 5 for my campaign - the maps are terrific for a claustrophobic feel and such an interesting environment. My players enjoyed it a great deal.
This was a great one shot adventure. It was easy to run with good descriptions and enough lore to make it feel real to my players and I. The only hiccup was my players being unsure with what to do at the end without enough information but this was also my first session ever as DM so I am sure any experienced DM could have easily resolved this. A+! Thanks for this great content.
