As happens every year, the coach paves the way in the dark of night through the mountains to the Devil's Castle – but this time the signs are more ominous than ever before! Fateful events can influence both the dangerous journey and the machinations of the passengers. An additional mysterious stranger boards the coach and all gasp... Which of the two secret societies will prevail on the next trip to the Devil's Castle – or will the traitor triumph in the end? In Die dunkle Prophezeiung, an expansion for The Castle of the Devil (aka Die Kutschfahrt zur Teufelsburg or Coachride to Devil's castle), the coach driver now takes on a significant role, a traitor sits among those in the carriage, and unimaginable events will have everyone guessing and second-guessing what to do next.
