From publisher blurb:
A Mini-Dungeon adventure for 4 PCs of Level 2
For centuries this dungeon lay beneath the surface of a broad, shallow lake, the headwaters of a meandering river. The river’s source was no natural spring, however, but a set of decanters of endless water. Aeons of unnatural erosion have fi nally done their work, and a sinkhole has recently formed beneath the river. As several decanters fell into the depths below, the once mighty torrent has dwindled. The lake receded into a mere stream, causing severe drought downriver. Worse, the sinkhole has opened the way for dangers more fearsome than drought.
A massive network of underground passages now lies revealed, and the PCs must brave these depths if they are to recover the missing decanters and restore the broken river.
