Secrets of the Subterranean Mansion

Publisher's blurb:

A mysterious old building has been rediscovered. Rumors of treasure, magic, and monsters abound. But who will be brave enough to uncover the Secrets of the Subterranean Mansion?

This adventure is a dungeon crawl featuring a large amount of exploration and combat with relatively few social encounters. The adventure itself barely has a story, but it does have the potential for a climatic (or anti-climatic) finale depending on how the players decide to play their characters.
