This adventure had always been something of a Holy Grail for me. I was a huge fan of Tom Moldvay, I had heard this adventure took place in Glantri and it was full of horror elements. As time went on and I still never found a copy I began to hear more; that it was a crazy dungeon full of crazier NPCs. That it is was more of a thinking module and not a hack and slash one and finally it was heavily influenced by Clark Ashton Smith, whom I always felt was superior to Lovecraft in many respects.
I did finally get a copy, paid a lot for it and I also got a copy here.
The module lives up to the hype. It is not a particularly easy module to run and you better spend a lot of time with it. But for me at that time (the mid 90s when I finally got a copy) it became a great addition to my growing Ravenloft collection. It was not officially part of Ravenloft mind you, but so much of it feels the same that is would have been a crime not to bring them together.
This is one of the last of the truly classic modules.
