From publisher blurb:
To End The Risingis an OSRIC(tm) module designed for 6-10 adventures of levels 1-3.
The shores of Lake Selmar, and the village of Prallis, are normally tranquil – except during the Rising. Every five years, a host of fearsome monsters emerges from the lake to lay waste to the village. The locals have endured this terror for decades, but now innocent travellers have been attacked. Can the party put an end to the Rising, forever?
