From the introduction:
This project was inspired by the re-release of the core books of the Advanced version of the world’s most famous FRPG. At the time of the announcement, I was thrilled that these books were to be re-released; however, I personally would have preferred if the entire library had been made available in various forms. I was subsequently challenged to re-imagine one entry in the library rather than simply wait for that library to see the light of day. This module is my answer to that challenge — a re-imagined version of the first module in the classic A-series.
While this is written for the retro-clone Labyrinth Lord™ using the Advanced Edition Companion™ expansion and inspiration from The Realms of Crawling Chaos™, it is still easily used with the re-released core books with little to no conversion for those who are interested.
