"Then she did confesse that she gained her powers from a Devill which did come to her out of the baye on moonless nights. And upon examination, we did find the markes of evill upon her, for she bore scales like unto a fish about her bodie. And so was she hanged as a witche, and upon the scaffolde she did crie out “Ia! Ia! Cthulhu fhtagn!” and those who did witnesse this were sore afraide, but her Devill answered her not, and she did die in that place.”

– Fear-the-Lord Grimshaw, Witch Finder, 1645

England has descended into civil war. The earth is tainted by alchemical magick. Giant clockwork war machines lumber across the land. In the remote countryside, witches terrorise entire villages, while in the hallowed halls of great universities, natural philosophers uncover the secrets of nature.

War, plague and religious division make people’s lives a constant misery. But even greater threats exist. Witches whisper of the old gods. Royalist alchemists pore over John Dee’s forbidden translation of the Necronomicon, dreaming of powers that will allow them to win the war. Parliamentarian engineers consult with creatures from beyond the crystal spheres and build blasphemous mechanisms, unholy monuments to their alien overlords. Vast inter-dimensional beings seek entry into the world, while their human servants, corrupted, crazed and enslaved, follow the eldritch agendas of their hidden masters.
