Arkham Horror RPG - Adventure, Three Days to the Big Easy (Free RPG Day 2026)

Welcome to the world of Arkham Horror! In these pages you can find an adventure that plunges you into the middle of the United States at the height of the Roaring Twenties. America in the 1920s is known for jazz, a newly emancipated generation of women, a world scarred by the memory of war, the Prohibition of alcohol in the United States, and the rise of organized crime. However, in Arkham Horror, these elements have blended with supernatural horrors beyond your understanding. Scheming cults, terrible monsters, and immensely powerful ancient beings mix with mobsters, flappers, and G-men to create a setting ripe for mystery and adventure.

in this setting, the players take on the role of investigators, individuals who for a variety of reasons have become aware of the supernatural forces haunting the edges of reality.

Instead of retreating when confronted with these sanity-shattering terrors, they choose to stand and fight. Whether out of altruism and a heroic impulse, the burning desire for revenge, or a simple drive to survive, these doughty few must stretch their endurance, courage, and mental fortitude to the limit as they work to uncover and combat the plots of beings who seek to unleash terror across the world.

Although the core of Arkham Horror focuses on the city of Arkham, Massachusetts and its surroundings, the setting stretches far beyond New England. The alien minions of the Ancient Ones and their foul cults can be found in every corner of the globe. Anywhere one goes, they may stumble across some primordial menace, whether it's a gin joint in Morocco or a steamboat cruising down the Mississippi.
