The scenario Sabre River involves an expedition to the Tower of Terror. The module includes a dungeon inside an active volcano, an underground river trip, and a new monster called the sabreclaw.
A mysterious curse has hit a barony in the realm of Norworld: The waters of the Sabre River have been tainted, bringing death or evilness to all who drink from them. The player characters are charged to seek out the source of this curse, in the company of Cutter, a young boy who is strangely immune to the effects of the curse. In fact, Cutter plays a more vital role in the restoring of Sabre River than one would expect.
