Three days in chains in the dungeon of his own castle is long enough to start asking the dark for an ending. The men who killed his family are upstairs, drinking his wine. Down here, a vampiress has been listening, and she has a better idea: his soul in exchange for exactly what he asked for, and then some. He takes it. Three nights later he wakes up, and the next man to come down the stairs is about to have a very bad night.
You play the lord, now undead and newly interested in revenge. Two trails lead out of the castle: the vampiress who made him, who stays one step ahead and visibly enjoys it, and the leader of the band that raided it. Each town between him and them is a stage with more than one way through, and the game does not tell you how many.
In development.
