Of Wrath and Blood is a classic 1920's Call of Cthulhu adventure. It was designed as a sequel to Chaosium’s classic introductory adventure, The Haunting, but it is also fully playable as a stand-alone adventure. This scenario was written as a submission into the October 2010 “And Theeeennn?” contest presented by www.yog-sothoth.com, a popular Call of Cthulhu RPG fan website. At the time of its submission, this adventure was titled The Haunted, but the author has changed the title for this current publication. This adventure was awarded Second Prize in the “And Theeeennn?” contest.
