From the introduction:
Welcome to The Lightless Beacon, this year’s Call of Cthulhu scenario for the first Greg Stafford Day—a day to celebrate the life and works of Greg and The Chaosium he founded way back in 1975. We hope you’ll be able to gather some friends and enjoy this scenario together.
The Lightless Beacon is set on Beacon Island, near Rockport, Massachusetts, on April 12th, 1926. It is intended as a short introductory scenario for novice Keepers, new players, or both! Experienced players and Keepers should also find something to enjoy here, too. Designed to be run in as little as one hour, this game is ideal for those who don’t have the time for a longer game session, or are just building up their confidence with the Call of Cthulhu RPG.
While The Lightless Beacon is presented as a standalone adventure and comes with four pre-generated investigators (enabling you to dive right in), it could also form the start of a new campaign, as it throws together complete strangers and plunges them into the world of the Cthulhu Mythos before they have a chance to catch their breath. There’s a mystery to solve, a threat to overcome, and a glimpse at the true horrors lurking in the darkness: all key themes of a good Call of Cthulhu adventure!
