Secret Hold of the Slaver Lords (OSR)

From publisher blurb:

Foul rumours of smuggling and piracy have ever-hung over the dismal village of Coldwater and its folk. But recently, lone travellers have been going missing in the village’s environs, and some whisper that the Slaver Lords’ scarlet sailed ships have been seen in the region. Who but the characters can uncover the truth of the matter, discover the slavers’ secret hold and rescue their doomed, helpless victims?

This Dungeon Backdrop is designed for the village of Coldwater in the Ashlar mini-campaign setting but can be easily inserted into almost any fantasy campaign.
