From publisher blurb:
Adventure At Goldmarsh provides you with two resources.
First is the adventure itself (Adventure at Goldmarsh), one wherein the party must stop another band of adventurers from waking an ancient power. This adventure starts with an investigation followed by a trip through a marsh, an exploration of a ruin and culminates in a battle in the past.
The second is a complete village (Goldmarsh) for the party to explore and interact with. The village is completely system-free and can provide many adventures just from the descriptions therein.
Simple stats are provided for OSR retroclone type systems, and as such, this module works best for characters around 5th level. However, it is very easy to import stats from your favorite game system and run it at any level.
