5 PCs, all 3rd level started the night. 1 made it home. All had a great time though.
This is a creepy, atmospheric site adventure. Officially written for 1e D&D, it easily converts to any system due to being mostly descriptions and events, rather than stat blocks. I ran it in Pathfinder and did most of the conversions on the fly.
It is combat light...as long as the players don't go poking around. If they go in determined to do what they came to do and make it out at no cost, they probably will. It is the curious, the stupid, and the morally inflexible who will not make it out alive.
Every trap has a logic behind it. Every encounter can be avoided. And most of my players, who do NOT take PC death well, all contacted me today to tell me how it was one of the best session of any campaign, any DM, they had ever had. The atmosphere of the first 3/4 of the adventure is just perfect. The players were getting up and pacing the room because they were to tense. They trusted NOTHING and kept waiting for the crud to hit the fan.
Certainly one of the best modules I've ran.
