From the introduction:
This is an adventure I wrote in 1988 when I was a teenager. So, it’s about as Old Skoool as it gets… not in an OSR sense, but in a “I’ve made a dungeon who wants to play” kind of way.
If you’re looking for understandable/sensible dungeon ecology, themes, plot, and balanced encounters etc., then (go back to the tavern) you’ve signed up for the wrong adventure!
The scenario is implemented and published as an interactive XSLX workbook for Microsoft Excel.
