This module does not contain a synopsis of the adventure, what the plot is, what the storyline is, nor who the main NPC's are. You have to read the 96(?) pages to learn who/what/where/when.
I searched YouTube for a review, to learn what the story was all about. The reviewer stated that there are problems with it, as it was started by Gygax, and finished by others, after Gygax was ousted from TSR.
To be honest, I will never run it. I have no interest in reading it, much less running it, after hearing the synopsis from a DM who slogged his way through it all. Sorry. It may be a "classic", but not in my book. Cheers!
