Into The Dung-eon - An O5R Adventure

From the publishers blurb:

"The city of Graygale is in trouble.

Its once-famed sewer system is on the verge of collapse and the authorities are struggling to find volunteers to clean up the mess. Luckily, the PCs are on hand to delve into the depths and flush out the problem.

The original idea came about in a post-gaming pub session in Oxford! The discussion considered how fantastic a mediaeval sewer would be with all the magic available to maintain it. This gave me the inspiration for an adventure where these magnificent waterworks had failed, and a group of ne'er-do-well adventurers would be ideal to fix it. I was also keen to create a mega-dungeon, which I think I have 'produced'."
