From the publisher: Welcome to the sourcebook for Department 13, Avalon Game’s science fiction/horror game. This sourcebook is based on the Infinite Futures game engine, which is Pathfinder compatible, but the source material can be used for any campaigns based in an alternative history where the Nazi regime has succeeded in global domination through arcane magics. Department 13 is set in the late 1950s to early 1960s, but can be readily altered for nearly any era.
