from the introduction: The Sins Of our Fathers is a complete scenario written for Warhammer Fantasy Roleplay for characters just starting their advanced careers. This adventure can be used as part of an existing campaign or if you prefer, simply as a one off. Originally the scenario was conceived as a possible extension to the River encounter ‘The Maria Borger’ from the ‘River Encounters’ supplement to ‘Death on the Reik’. This connection assumes that Graf Orlock escaped from the players clutches during that encounter. This is handled by having Orlock turn etherial in his coffin and materialize to fight the PC’s before they stake him through the heart in the course of their investigations onboard the Maria Borger. You should arrange for his escape before he is destroyed in the fight. The adventure can still be used without this encounter having been played out but works far better and adds greater weight to this scenario as a pre-cursor. This sets Orlock up as a nemesis character for the PC’s. Some distance should be put between running the river encounter and this adventure to allow the dust to settle. When their attention is elsewhere you can start this adventure allowing them to reaquaint themselves with their previous advesary...
