A Eunuch for Zamzer
This adventure is mildly inspired by "Zanzer's Dungeon" from the 1991 "New and Improved" Dungeons & Dragons box set, but it would more accurately be described as a parody. In 2008 I DMed this new version for some of the same friends that played the original in 1991.
This dungeon is intended to be played inside out, with the PCs starting in the prison and finding a way out, while trying to avoid becoming Zamzer's eunuch. It can also be used in the usual manner where the PCs enter on purpose to find treasure, rescue prisoners, or destroy a villain (in which case Zamzer may be the first encounter!)
