Publication:The Treasure of the Hideous One
This adventure follows along relatively traditional paths. The group of player characters finds a message that indicates a long hidden treasure lies somewhere in a swampy region. An expedition led by an intrepid explorer attempted to find the treasure but came to an untimely end.
The group eventually fights their way through various enemies to secure the treasure and learn the fate of the original expedition. The module lists several possible treasures to choose as the final reward.
Despite the shortness of the adventure it requires a fairly advanced party because of the presence of Rosentos the Vampire.
