You haven't been a vampire long, but you've been one long enough to accidentally kill your first proper meal. When your sire made the pitch, he talked a lot about endless nights of hedonism and intrigue... and very little about the grim, bloody cost that makes it possible.
You dealt with it, and he wants to find out how. Step by bloody, gruesome step.
This game is a parody of Vampire: The Masquerade.
