The little fishing town of Saltmarsh is threatened! Why are lizard men gathering force nearby and why have they been buying large quantities of weapons? A party of bold adventures must answer these questions or the people of Saltmarsh will never live in peace!

Danger at Dunwater is the second part in a series of three modules designed and developed in the United Kingdom for beginning adventurers with the AD&D rules. Its plot follows direct from that of the first part (Module U1 - The Sinister Secret of Saltmarsh). This adventure can be played by 6-10 characters of level 1-4. This module contains large- scale maps, full background information and detailed encounter descriptions for the players and DM.
