Mark L. Chance has written an excellent adventure featuring one of my hand drawn maps. “The Tombs of the Whispering Worms” is a descent into madness for Swords & Wizardry or other old school fantasy games. The adventure was recently featured on TSRs blogsite Multiverse, and is available as a free pdf download.
Here’s an image of page 1 (linked to the pdf) and a high resolution unnumbered image of the original map. Hope you enjoy the whispering worms!
