From publisher blurb:
Tillius Morganstein aka the Mad Mage has selected your group to investigate an ancient temple hidden below the peaceful waters of Lake Springwood. The wizard is too old to investigate the area himself and has enlisted your help. While he has studied the ancient texts dedicated to "Bulu" he cannot define what dangers may lurk or what treasures may await those brave enough to delve into the submerged halls but surely the rewards will be great!
This adventure is suitable for adventure groups of level 4-6.
This adventure setting was designed for 1st/2nd Edition AD&D for the Filbar Campaign, however it is easily adaptable to most any game and system. Save yourself some time and utilize it for a one shot adventure or a continuing campaign!
