Your friends cannot be trusted, your knowledge means nothing, and everything you hold dear turns to dust. The Final Revelation collects for the first time the Purist adventures for Trail of Cthulhu written by award winning RPG writer Graham Walmsley. With a framing scenario by Scott Dorward, The Final Revelation gives your Trail of Cthulhu Investigators the opportunity to play through a Purist campaign set in the United Kingdom of the 1930s where there is no escape, no comfort and no salvation when faced with the Mythos. Your Investigators are powerless and insignificant; your only choices death, insanity or a quiet life with a shattered mind. The Final Revelation contains five Purist adventures for Trail of Cthulhu – The Final Revelation, The Dying of St Margaret’s, The Watchers in the Sky, The Dance in the Blood and The Rending Box.
