From publisher blurb:
This is the first in the Galligron Series of adventures. These adventures are designed to be truly modular. While they are all connected, each can be used separately; dropped into your home campaign with little trouble.
This first adventure is for 1st level characters, and may take them to 4th level by its completion.
The village of Sableford has a problem with goblins, and they have sent out a call for able bodied adventurers. The goblins are only the tip of the iceberg, however, as the adventurers soon discover.
This is a classic dungeon crawl that will challenge even the most experienced players.
