In the first few years of the 21st Century, the Legacy of Kain was a big action-adventure video game franchise. A high-concept gothic horror story that mixed complex vampire mythology with time travel, heady philosophy, and even aliens (sort-of), the five games in the series are still cited as some of the most ambitious projects in the entire industry. However, the increasingly convoluted--though impressively consistent--plot, along with at least one lackluster title, Blood Omen 2, kept the franchise from bringing in many new players. As such, it declined in popularity about as quickly as it rose, and poor sales for the fifth entry, Defiance, caused the cancellation of a planned sixth (and allegedly final) game, The Dark Prophecy, back in 2004. Since then, it has been largely assumed that the legacy is dead.
Still, the rumor mill has been stirring lately with the possibility that the franchise may be born again, like Raziel from his Sarafan crypt.
