A good long dungeon crawl with classic Gygax puzzles. The artwork inside is great, don't let the cover art fool you. The dungeon is linear, like much most '80s RPG modules - none of that "let the players go where they want" atmosphere in these games. This was one of the best modules back in the day, coming out at the end of a decade of gaming modules. In the original shrinkwrap in mint condition. Collectable for any RPG collector.
