A 1920s campaign for Call of Cthulhu, written by one of the translators of the Polish edition and published in Polish only. Apart from a full campaign (that shares some common themes with Day of the Beast) it features a description of a world on the edge of Dreamlands and an extensive write up of a secret society (both featured prominently in the scenarios), and some expanded notes on alchemy in the world of Call of Cthulhu.
