Alone Against the Frost is a solo horror adventure for one player, set during a research expedition to Canada’s Northwest Territories during the 1920s. Here, you choose your own path as you navigate through the story—your choices will determine whether you find success or failure!

What has Professor Harris’ research got to do with the strange green fog enveloping the town? Who are the menacing, dark-suited men that arrived on the ferry with your investigator? And, why is a Buddhist monk visiting Esbury, a town more used to entertaining New England’s wealthy elite?

Take on the role of an investigator traveling to a remote lakeside town where strange things are happening. Decide your path through the story, and the fate of the citizens of Esbury!

Cthulhu Dark Ages is a world lit only by fire. The ancient empires collapsed centuries ago, taking their culture and learning with them. It’s a dark world and people are right to be afraid of the dark. Apart from the Viking raiders, witches, and outlaws, there are the unquiet dead, ancient horrors, and other malevolent beings stalking the countryside. Dark entities, beyond good and evil, wait hidden in the recesses of time and the angles of space. A few brave souls try their best to resist the horrors and push them back from whence they came.
