A One-Round Living Greyhawk Gran March Regional Adventure
From the introduction:
Many civilians have disappeared along the roads leading to Orlane while other travelers claim to have narrowly escaped goblinoid attacks in these areas. Military command does not have the resources at this time to launch an investigation into these attacks. Indeed, the military forces in the area have had no recent encounters with goblins.
This scenario is intended for characters of levels 3 - 10.
