The confused man who walked into Father Langley's confessional that afternoon brought more than his sins. He carried a case holding the most terrible of secrets. In his shadow tread a team of assassins charged with destroying all who discover the contents. It is up to the priest's handyman, Mordecai, a trained and disenchanted death dealer but the kind of soldier the cleric needs right now to find a resolution.
But there is an evil presence in the world beyond those known by the players and whilst Father Langley and Mordecai fight their own battle, another unseen and more esoteric war is going on between the forces of Good and Evil.
