On release back in 1981, the initial setting of Call of Cthulhu focused upon the "classic" 1920's-era of the early twentieth century - the time of H.P. Lovecraft. It did not take long for players to realize the potential of the game -that it could adapt easily to other time periods.

Over the last thirty-plus years, players have been confronting the Cthulhu Mythos in all manner of historical settings: be it the Dark Ages, Imperial Rome, the Dreamlands, Victorian Gaslight-era, or even the far future! The minions of the Great Old Ones can always be found, lurking in the shadows.

The latest edition of Call of Cthulhu includes investigator occupations, equipment, and weapons for both the 1920's and modern-day settings, allowing for games to be set either time-frame. In due course, other published settings will be updated to the latest edition of the rules; however, Cthulhu Through The Ages has been created to help players adopt the latest rule set for the wide range of settings published by Chaosium.

Here you will find straight-forward guidance and era-specific rules for investigator creation for seven different settings. Also offered are updated rules for combat and a sprinkling of other topics like scenario seeds, setting-specific monsters, and investigator organizations.
