Strange Aeons is the nineteenth Pathfinder Adventure Path campaign and ran from August 2016 to February 2017. Announced at Gen Con 2015, it features Lovecraftian elements, including elder gods, mental illness, and the Necronomicon. The first issue was written by F. Wesley Schneider.

The Adventure Path includes dozens of Lovecraftian creatures under a special agreement with Chaosium Inc., and numerous connections to Horror Adventures.

“In a distant land polluted by an alien menace from beyond the stars, a great cancer grows within the earth. As its tendrils reach out through the dreams of those who learn and study its existence, a sinister cult grows more active in preparing the way for a devastation that will destroy more than the minds of would-be heroes. Can the adventurers reclaim lost memories in time to stop the advance of a cataclysmic contagion that could threaten all of Golarion? Can they resist the mind-shattering truths revealed by the Yellow Sign, and the monstrous force it symbolizes? The Strange Aeons Adventure Path pits the heroes against the cosmic horrors of the Cthulhu Mythos, with new monsters, mind-shattering terrors, and explorations far beyond the known lands of Golarion.”
