Oh man, I feel like there just isn't any content here. This dungeon requires three other supplements/resources to work and is chock full of encounters that do not seem to interact with each other. I feel like players exploring this place would never be able to learn its history or theme by investigation and environmental storytelling. 

Also, I thought the point of procedural-generation tables is to provide inspiration before writing an adventure, not to replace content in a "finished" product. Why is the module asking GMs to roll the treasures themselves? GMs can do that on their own. If they wanted to do that, they would have just written their own adventure with the help of those tables rather than actively seeking out a pre-written product. 

Points for being PWYW and the multi-level dungeon map, though.
