From publisher blurb: “I threw on the current of the Crookes tube apparatus, and focussed toward that scene of immortal blasphemousness the strongest ether radiations which men's art can arouse ...” Cthulhu Eternal is a multi-era, setting agnostic ruleset which aims to support inventive game designers who have original ideas for Lovecraftian roleplaying games or scenarios. It draws upon the long line of D100 games of Cthulhu-themed investigation, offering a beautifully streamlined and elegant set of mechanics to support a diverse range of gaming styles. Different eras of human history each have their own flavor and character – due in part to the technology available, and in part due to social conventions of the day. Recognizing this, Cthulhu Eternal exists as a family of inter-related rules engines – each based on the same mechanics but tailored to the needs of a specific era. This version of Cthulhu Eternal is specially designed to support Lovecraftian games set in the “Jazz Age” – that is, world as it was in the early 20th Century (between the World Wars). This is an attractive option for a game setting as it was the then-contemporary world in which H.P. Lovecraft set many of his novellas and short fiction.
