From the campaign:
This is the third expansion to the Castle of the Mad Archmage megadungeon adventure. In this adventure, the characters are catapulted to a parallel dimension called Musicland where musical instruments are alive, people speak in musical notes, and the King of Instruments produces melodies that embody the Platonic ideal of music itself.
Not only will the adventurers need to navigate this strange and deadly place, but they will need to figure out a way home, as well. But where there is great peril, there is always promise of great reward, and treasures both mundane and magical await those who enter Musicland.
This Kickstarter will be used to fund art and editing for the adventure. In addition to the PDF version, there will be a limited edition hand-produced print version in a very limited numbered edition of 100 numbered and signed copies, exclusive to this Kickstarter, which will never, ever, be produced again. This is a truly unique opportunity to get a bit of OSR gaming history.
The original Castle of the Mad Archmage has more than thirteen levels and over 1,500 keyed encounters of perils, monsters, traps, and treasure to bedevil your players. There are levels of warring humanoids, the deadly Arena, ancient artifacts, lost temples, portals to other worlds, and the ultimate secret of the dungeons... the Mad Archmage himself. And now it's getting even bigger!
