Adventure at Goldmarsh - This is an adventure for 5th level characters from Lupus Rex games. 39 pages, $4. Sounds interesting:
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.Ryubix - Already mentioned, a 20th level haunted manor adventure. 90-something pages, $10.
