[from the back of the book]
This new adventure campaign is set in 1927 from Berlin via Breslau and Danzig to East Prussia. As escaped test subjects for blasphemous human experiments, the investigators turn the tables and the hunted become hunters. While their bodies and souls slowly transform into something strange, the trail leads east ... to the borderland.
They will meet unscrupulous business people, cold-blooded professional criminals, reactionary officers and mad medical doctors. They have to fight back against mutated humans and cruel Mythos creatures. In the struggle for their own humanity, they are confronted with the fate of Königsberg. Can they destroy the new governor of the Black Goat or do they have to see the end of the world?
Grenzland leads the players in six varied and closely interlinked episodes into an area that will be the scene of cthuloid horrors for the first time: East Prussia!
