Fresh Horror Delivered to your doorstep EVERY MONTH!

In Yig Snake Granddaddy, the new Cthulhu Mythos 5e campaign, evil serpent folk seek to bring back prehistoric times, complete with pterodactyls, dinosaurs, and other monstrous beings.

In Land Out of Time, the first act of four, your player characters adventure into the wilds of Yilan, a primeval wilderness infested with carnivorous slime molds, gigantic crocodiles, and other lost horrors. The heroes encounter an evil serpent wizard, who prepares for an evil ritual beyond belief.

Betrayed, marooned, and hunted by super-intelligent enemies, can the heroes even survive, yet alone prevail?

Each act is 75+ full color pages in hardcover...

...with new monsters to fight...

...and new locations to explore!

Your subscription includes FREE character sheets to help keep track of the action. This beautifully laid out PDF can be printed as often as you like and will be a great enhancement to your friends' Cthulhu-based adventures.
