From the introduction: The people of Halpstadt live in fear. A few weeks ago the ghost of Valamir the Crimson, an evil pirate burned in the village many years ago, returned and began haunting the lands around the village. However when the PCs investigate they will find that the haunting never really took place, it was all a trick designed by the local landlords to keep the villagers from investigating a slaver band operating in the area.
